= Exception: `org.xml.sax.SAXParseException`

----
The reference to entity "..." must end with the ';' delimiter.

In the URIs used for specifying Camel endpoints, the `&` is used to
separate the parameters. However, `&` also is a reserved character in
XML.
Because of this, you have to replace all & in your URIs by `+&amp;+` when
using the Spring XML syntax to configure Camel routes.

An example: this snippet of code in the xref:ROOT:dsl.adoc[DSL]...

[source,java]
----
from("timer://myTimer?fixedRate=true&delay=0&period=2000")
----

...matches this example in the Spring XML syntax:

[source,java]
----
<from>timer://myTimer?fixedRate=true&amp;delay=0&amp;period=2000</from>
