*Since Camel {since}*

*{component-header}*

The Spring WS component allows you to integrate with
http://static.springsource.org/spring-ws/sites/1.5/[Spring Web
Services]. It offers both _client_-side support, for accessing web
services, and _server_-side support for creating your own contract-first
web services.

Maven users will need to add the following dependency to their `pom.xml`
for this component:

[source,xml]
------------------------------------------------------------
<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-spring-ws</artifactId>
    <version>x.x.x</version>
    <!-- use the same version as your Camel core version -->
</dependency>
------------------------------------------------------------

[NOTE]
====
*Dependencies*

This component ships with Spring-WS 2.0.x which (like
the rest of Camel) requires Spring 3.0.x. In order to run earlier versions of
`camel-spring-ws` on Spring 2.5.x you need to add the `spring-webmvc`
module from Spring 2.5.x. In order to run Spring-WS 1.5.9 on Spring
3.0.x you need to exclude the OXM module from Spring 3.0.x as this
module is also included in Spring-WS 1.5.9 (see
http://stackoverflow.com/questions/3313314/can-spring-ws-1-5-be-used-with-spring-3[this
post]).
====

== URI format

The URI scheme for this component is as follows

[source,java]
------------------------------------------
spring-ws:[mapping-type:]address[?options]
------------------------------------------

To expose a web service *mapping-type* needs to be set to any of the
following:

[width="100%",cols="10%,90%",options="header",]
|=======================================================================
|Mapping type |Description

|`rootqname` |Offers the option to map web service requests based on the qualified
name of the root element contained in the message.

|`soapaction` |Used to map web service requests based on the SOAP action specified in
the header of the message.

|`uri` |In order to map web service requests that target a specific URI.

|`xpathresult` |Used to map web service requests based on the evaluation of an XPath
`expression` against the incoming message. The result of the evaluation
should match the XPath result specified in the endpoint URI.

|`beanname` |Allows you to reference an
`org.apache.camel.component.spring.ws.bean.CamelEndpointDispatcher`
object in order to integrate with existing (legacy)
http://static.springsource.org/spring-ws/sites/1.5/reference/html/server.html#server-endpoint-mapping[endpoint
mappings] like `PayloadRootQNameEndpointMapping`,
`SoapActionEndpointMapping`, etc
|=======================================================================

As a consumer the *address* should contain a value relevant to the
specified mapping-type (e.g. a SOAP action, XPath expression). As a
producer the address should be set to the URI of the web service your
calling upon.

You can append query *options* to the URI in the following format,
`?option=value&option=value&...`

== Options


// component options: START
The Spring WebService component supports 4 options, which are listed below.



[width="100%",cols="2,5,^1,2",options="header"]
|===
| Name | Description | Default | Type
| *bridgeErrorHandler* (consumer) | Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored. | false | boolean
| *lazyStartProducer* (producer) | Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel's routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing. | false | boolean
| *autowiredEnabled* (advanced) | Whether autowiring is enabled. This is used for automatic autowiring options (the option must be marked as autowired) by looking up in the registry to find if there is a single instance of matching type, which then gets configured on the component. This can be used for automatic configuring JDBC data sources, JMS connection factories, AWS Clients, etc. | true | boolean
| *useGlobalSslContextParameters* (security) | Enable usage of global SSL context parameters. | false | boolean
|===
// component options: END



// endpoint options: START
The Spring WebService endpoint is configured using URI syntax:

| *endpointMapping* (consumer) | Reference to an instance of org.apache.camel.component.spring.ws.bean.CamelEndpointMapping in the Registry/ApplicationContext. Only one bean is required in the registry to serve all Camel/Spring-WS endpoints. This bean is auto-discovered by the MessageDispatcher and used to map requests to Camel endpoints based on characteristics specified on the endpoint (like root QName, SOAP action, etc) |  | CamelSpringWSEndpointMapping
| *exceptionHandler* (consumer) | To let the consumer use a custom ExceptionHandler. Notice if the option bridgeErrorHandler is enabled then this option is not in use. By default the consumer will deal with exceptions, that will be logged at WARN or ERROR level and ignored. |  | ExceptionHandler

By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel's routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing. | false | boolean
| *messageFactory* (producer) | Option to provide a custom WebServiceMessageFactory. For example when you want Apache Axiom to handle web service messages instead of SAAJ. |  | WebServiceMessageFactory

| *timeout* (producer) | Sets the socket read timeout (in milliseconds) while invoking a webservice using the producer, see URLConnection.setReadTimeout() and CommonsHttpMessageSender.setReadTimeout(). This option works when using the built-in message sender implementations: CommonsHttpMessageSender and HttpUrlConnectionMessageSender. One of these implementations will be used by default for HTTP based services unless you customize the Spring WS configuration options supplied to the component. If you are using a non-standard sender, it is assumed that you will handle your own timeout configuration. The built-in message sender HttpComponentsMessageSender is considered instead of CommonsHttpMessageSender which has been deprecated, see HttpComponentsMessageSender.setReadTimeout(). |  | int
| *webServiceTemplate* (producer) | Option to provide a custom WebServiceTemplate. This allows for full control over client-side web services handling; like adding a custom interceptor or specifying a fault resolver, message sender or message factory. |  | WebServiceTemplate
| *wsAddressingAction* (producer) | WS-Addressing 1.0 action header to include when accessing web services. The To header is set to the address of the web service as specified in the endpoint URI (default Spring-WS behavior). |  | URI
| *sslContextParameters* (security) | To configure security using SSLContextParameters |  | SSLContextParameters

|CamelSpringWebserviceAddressingOutputAction |URI |Use this header to specify the WS-Addressing Action , overrides
outputAction option if present

|CamelSpringWebserviceAddressingFaultAction |URI |Use this header to specify the WS-Addressing Fault Action , overrides

|=======================================================================

== Accessing web services

To call a web service at `\http://foo.com/bar` simply define a route:

[source,java]
---------------------------------------------------------
from("direct:example").to("spring-ws:http://foo.com/bar")
---------------------------------------------------------

And sent a message:

[source,java]
------------------------------------------------------------------------------------------------------------
template.requestBody("direct:example", "<foobar xmlns=\"http://foo.com\"><msg>test message</msg></foobar>");
------------------------------------------------------------------------------------------------------------

Remember if it's a SOAP service you're calling you don't have to include
SOAP tags. Spring-WS will perform the XML-to-SOAP marshaling.

== Sending SOAP and WS-Addressing action headers

When a remote web service requires a SOAP action or use of the
WS-Addressing standard you define your route as:

[source,java]
-----------------------------------------------------------------------------------------------
from("direct:example")
.to("spring-ws:http://foo.com/bar?soapAction=http://foo.com&wsAddressingAction=http://bar.com")
-----------------------------------------------------------------------------------------------

Optionally you can override the endpoint options with header values:

[source,java]
--------------------------------------------------------------------
template.requestBodyAndHeader("direct:example",
"<foobar xmlns=\"http://foo.com\"><msg>test message</msg></foobar>",
SpringWebserviceConstants.SPRING_WS_SOAP_ACTION, "http://baz.com");
--------------------------------------------------------------------

== Using SOAP headers

*Since Camel 2.11.1*

You can provide the SOAP header(s) as a Camel Message header when
sending a message to a spring-ws endpoint, for example given the
following SOAP header in a String

[source,java]
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------
String body = ...
String soapHeader = "<h:Header xmlns:h=\"http://www.webserviceX.NET/\"><h:MessageID>1234567890</h:MessageID><h:Nested><h:NestedID>1111</h:NestedID></h:Nested></h:Header>";
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------

We can set the body and header on the Camel Message as follows:

[source,java]
----------------------------------------------------------------------------------------
exchange.getIn().setBody(body);
exchange.getIn().setHeader(SpringWebserviceConstants.SPRING_WS_SOAP_HEADER, soapHeader);
----------------------------------------------------------------------------------------

And then send the Exchange to a `spring-ws` endpoint to call the Web
Service.

Likewise the spring-ws consumer will also enrich the Camel Message with
the SOAP header.

For an example see this
https://svn.apache.org/repos/asf/camel/trunk/components/camel-spring-ws/src/test/java/org/apache/camel/component/spring/ws/SoapHeaderTest.java[unit
test].

== The header and attachment propagation

Spring WS Camel supports propagation of the headers and attachments into
Spring-WS WebServiceMessage response. The
endpoint will use so called "hook" the MessageFilter (default
implementation is provided by BasicMessageFilter) to propagate the
exchange headers and attachments into WebServiceMessage response. Now
you can use

[source,java]
--------------------------------------------------------------------
exchange.getOut().getHeaders().put("myCustom","myHeaderValue")
exchange.getIn().addAttachment("myAttachment", new DataHandler(...))
--------------------------------------------------------------------

[NOTE]
====
If the exchange header in the pipeline contains text, it generates
Qname(key)=value attribute in the soap header. Recommended is to create
a QName class directly and put into any key into header.
====

== How to transform the soap header using a stylesheet
The header transformation filter (HeaderTransformationMessageFilter.java)
can be used to transform the soap header for a soap request. If you want to use 
the header transformation filter, see the below example:

[source,java]
------------------------------------------------------------------
<bean id="headerTransformationFilter" class="org.apache.camel.component.spring.ws.filter.impl.HeaderTransformationMessageFilter">
    <constructor-arg index="0" value="org/apache/camel/component/spring/ws/soap-header-transform.xslt"/>
</bean
------------------------------------------------------------------
Use the bead defined above in the camel endpoint

[source,java]
------------------------------------------------------------------
<route>
    <from uri="direct:stockQuoteWebserviceHeaderTransformation"/>
    <to uri="spring-ws:http://localhost?webServiceTemplate=#webServiceTemplate&amp;soapAction=http://www.stockquotes.edu/GetQuote&amp;messageFilter=#headerTransformationFilter"/>
</route> 
------------------------------------------------------------------


== How to use MTOM attachments

The BasicMessageFilter provides all required information for Apache
Axiom in order to produce MTOM message. If you want to use Apache Camel
Spring WS within Apache Axiom, here is an example: 
- Simply define the messageFactory as is bellow and Spring-WS will use
MTOM strategy to populate your SOAP message with optimized attachments.

[source,java]
------------------------------------------------------------------
<bean id="axiomMessageFactory"
class="org.springframework.ws.soap.axiom.AxiomSoapMessageFactory">
<property name="payloadCaching" value="false" />
<property name="attachmentCaching" value="true" />
<property name="attachmentCacheThreshold" value="1024" />
</bean>
------------------------------------------------------------------

- Add into your pom.xml the following dependencies

[source,java]
----------------------------------------------
<dependency>
<groupId>org.apache.ws.commons.axiom</groupId>
<artifactId>axiom-api</artifactId>
<version>1.2.13</version>
</dependency>
<dependency>
<groupId>org.apache.ws.commons.axiom</groupId>
<artifactId>axiom-impl</artifactId>
<version>1.2.13</version>
<scope>runtime</scope>
</dependency>
----------------------------------------------

- Add your attachment into the pipeline, for example using a Processor
implementation.

[source,java]
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
private class Attachement implements Processor {
public void process(Exchange exchange) throws Exception
{ exchange.getOut().copyFrom(exchange.getIn()); File file = new File("testAttachment.txt"); exchange.getOut().addAttachment("test", new DataHandler(new FileDataSource(file)));  }
}
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

- Define endpoint (producer) as ussual, for example like this:

[source,java]
----------------------------------------------------------------------------------------------------------
from("direct:send")
.process(new Attachement())
.to("spring-ws:http://localhost:8089/mySoapService?soapAction=mySoap&messageFactory=axiomMessageFactory");
----------------------------------------------------------------------------------------------------------

- Now, your producer will generate MTOM message with otpmized
attachments.

== The custom header and attachment filtering

If you need to provide your custom processing of either headers or
attachments, extend existing BasicMessageFilter and override the
appropriate methods or write a brand new implementation of the
MessageFilter interface. +
 To use your custom filter, add this into your spring context:

You can specify either a global a or a local message filter as
follows: 
 a) the global custom filter that provides the global configuration for
all Spring-WS endpoints

[source,java]
--------------------------------------------------------------------------------
 
<bean id="messageFilter" class="your.domain.myMessageFiler" scope="singleton" />
--------------------------------------------------------------------------------

or
 b) the local messageFilter directly on the endpoint as follows:

[source,java]
-------------------------------------------------------------------------------------
to("spring-ws:http://yourdomain.com?messageFilter=#myEndpointSpecificMessageFilter");
-------------------------------------------------------------------------------------

For more information see
https://issues.apache.org/jira/browse/CAMEL-5724[CAMEL-5724]

If you want to create your own MessageFilter, consider overriding the
following methods in the default implementation of MessageFilter in
class BasicMessageFilter:

[source,java]
-------------------------------------------------------------------------------
protected void doProcessSoapHeader(Message inOrOut, SoapMessage soapMessage)
{your code /*no need to call super*/ }

protected void doProcessSoapAttachements(Message inOrOut, SoapMessage response)
{ your code /*no need to call super*/ }
-------------------------------------------------------------------------------

== Using a custom MessageSender and MessageFactory

A custom message sender or factory in the registry can be referenced
like this:

[source,java]
-----------------------------------------------------------------------------------------------
from("direct:example")
.to("spring-ws:http://foo.com/bar?messageFactory=#messageFactory&messageSender=#messageSender")
-----------------------------------------------------------------------------------------------

Spring configuration:

[source,xml]
---------------------------------------------------------------------------------------------------------------------
<!-- authenticate using HTTP Basic Authentication -->
<bean id="messageSender" class="org.springframework.ws.transport.http.HttpComponentsMessageSender">
    <property name="credentials">
        <bean class="org.apache.commons.httpclient.UsernamePasswordCredentials">
            <constructor-arg index="0" value="admin"/>
            <constructor-arg index="1" value="secret"/>
        </bean>
    </property>
</bean>

<!-- force use of Sun SAAJ implementation, http://static.springsource.org/spring-ws/sites/1.5/faq.html#saaj-jboss -->
<bean id="messageFactory" class="org.springframework.ws.soap.saaj.SaajSoapMessageFactory">
    <property name="messageFactory">
        <bean class="com.sun.xml.messaging.saaj.soap.ver1_1.SOAPMessageFactory1_1Impl"></bean>
    </property>
</bean>
---------------------------------------------------------------------------------------------------------------------

== Exposing web services

In order to expose a web service using this component you first need to
set-up a
http://static.springsource.org/spring-ws/sites/1.5/reference/html/server.html[MessageDispatcher]
to look for endpoint mappings in a Spring XML file. If you plan on
running inside a servlet container you probably want to use a
`MessageDispatcherServlet` configured in `web.xml`.

By default the `MessageDispatcherServlet` will look for a Spring XML
named `/WEB-INF/spring-ws-servlet.xml`. To use Camel with Spring-WS the
only mandatory bean in that XML file is `CamelEndpointMapping`. This
bean allows the `MessageDispatcher` to dispatch web service requests to
your routes.

_web.xml_

[source,xml]
-----------------------------------------------------------------------------------------------------
<web-app>
    <servlet>
        <servlet-name>spring-ws</servlet-name>
        <servlet-class>org.springframework.ws.transport.http.MessageDispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>spring-ws</servlet-name>
        <url-pattern>/*</url-pattern>
    </servlet-mapping>
</web-app>
-----------------------------------------------------------------------------------------------------

_spring-ws-servlet.xml_

[source,xml]
----------------------------------------------------------------------------------------------------
<bean id="endpointMapping" class="org.apache.camel.component.spring.ws.bean.CamelEndpointMapping" />

<bean id="wsdl" class="org.springframework.ws.wsdl.wsdl11.DefaultWsdl11Definition">
    <property name="schema">
        <bean class="org.springframework.xml.xsd.SimpleXsdSchema">
            <property name="xsd" value="/WEB-INF/foobar.xsd"/>
        </bean>
    </property>
    <property name="portTypeName" value="FooBar"/>
    <property name="locationUri" value="/"/>
    <property name="targetNamespace" value="http://example.com/"/>
</bean>
----------------------------------------------------------------------------------------------------

More information on setting up Spring-WS can be found in
http://static.springsource.org/spring-ws/sites/1.5/reference/html/tutorial.html[Writing
Contract-First Web Services]. Basically paragraph 3.6 "Implementing the
Endpoint" is handled by this component (specifically paragraph 3.6.2
"Routing the Message to the Endpoint" is where `CamelEndpointMapping`
comes in). Also don't forget to check out the
Spring Web Services Example included in the
Camel distribution.

== Endpoint mapping in routes

With the XML configuration in-place you can now use Camel's DSL to
define what web service requests are handled by your endpoint:

The following route will receive all web service requests that have a
root element named "GetFoo" within the `\http://example.com/` namespace.

[source,java]
----------------------------------------------------------------------------------------
from("spring-ws:rootqname:{http://example.com/}GetFoo?endpointMapping=#endpointMapping")
.convertBodyTo(String.class).to(mock:example)
----------------------------------------------------------------------------------------

The following route will receive web service requests containing the
`\http://example.com/GetFoo` SOAP action.

[source,java]
---------------------------------------------------------------------------------------
from("spring-ws:soapaction:http://example.com/GetFoo?endpointMapping=#endpointMapping")
.convertBodyTo(String.class).to(mock:example)
---------------------------------------------------------------------------------------

The following route will receive all requests sent to
`\http://example.com/foobar`.

[source,java]
--------------------------------------------------------------------------------
from("spring-ws:uri:http://example.com/foobar?endpointMapping=#endpointMapping")
.convertBodyTo(String.class).to(mock:example)
--------------------------------------------------------------------------------

The route below will receive requests that contain the element
`<foobar>abc</foobar>` anywhere inside the message (and the default
namespace).

[source,java]
--------------------------------------------------------------------------------------
from("spring-ws:xpathresult:abc?expression=//foobar&endpointMapping=#endpointMapping")
.convertBodyTo(String.class).to(mock:example)
--------------------------------------------------------------------------------------

== Alternative configuration, using existing endpoint mappings

For every endpoint with mapping-type `beanname` one bean of type
`CamelEndpointDispatcher` with a corresponding name is required in the
Registry/ApplicationContext. This bean acts as a bridge between the
Camel endpoint and an existing
http://static.springsource.org/spring-ws/sites/1.5/reference/html/server.html#server-endpoint-mapping[endpoint
mapping] like `PayloadRootQNameEndpointMapping`.

[NOTE]
====
The use of the `beanname` mapping-type is primarily meant for (legacy)
situations where you're already using Spring-WS and have endpoint
mappings defined in a Spring XML file. The `beanname` mapping-type
allows you to wire your Camel route into an existing endpoint mapping.
When you're starting from scratch it's recommended to define your
endpoint mappings as Camel URI's (as illustrated above with
`endpointMapping`) since it requires less configuration and is more
expressive. Alternatively you could use vanilla Spring-WS with the help
of annotations.
====

An example of a route using `beanname`:

[source,java]
------------------------------------------------------------------------------------------------------------------------
<camelContext xmlns="http://camel.apache.org/schema/spring">
    <route>
        <from uri="spring-ws:beanname:QuoteEndpointDispatcher" />
        <to uri="mock:example" />
    </route>
</camelContext>

<bean id="legacyEndpointMapping" class="org.springframework.ws.server.endpoint.mapping.PayloadRootQNameEndpointMapping">
    <property name="mappings">
        <props>
            <prop key="{http://example.com/}GetFuture">FutureEndpointDispatcher</prop>
            <prop key="{http://example.com/}GetQuote">QuoteEndpointDispatcher</prop>
        </props>
    </property>
</bean>

<bean id="QuoteEndpointDispatcher" class="org.apache.camel.component.spring.ws.bean.CamelEndpointDispatcher" />
<bean id="FutureEndpointDispatcher" class="org.apache.camel.component.spring.ws.bean.CamelEndpointDispatcher" />
------------------------------------------------------------------------------------------------------------------------

== POJO (un)marshalling

Camel's pluggable data formats offer support for
pojo/xml marshalling using libraries such as JAXB, XStream, JibX, Castor
and XMLBeans. You can use these data formats in your route to sent and
receive pojo's, to and from web services.

When _accessing_ web services you can marshal the request and unmarshal
the response message:

[source,java]
----------------------------------------------------------------------------------------
JaxbDataFormat jaxb = new JaxbDataFormat(false);
jaxb.setContextPath("com.example.model");

from("direct:example").marshal(jaxb).to("spring-ws:http://foo.com/bar").unmarshal(jaxb);
----------------------------------------------------------------------------------------

Similarly when _providing_ web services, you can unmarshal XML requests
to POJO's and marshal the response message back to XML:

[source,java]
--------------------------------------------------------------------------------------------------------
from("spring-ws:rootqname:{http://example.com/}GetFoo?endpointMapping=#endpointMapping").unmarshal(jaxb)
.to("mock:example").marshal(jaxb);
--------------------------------------------------------------------------------------------------------
