= Adding JARs to {brandname} Server installations
Make custom JAR files available to {brandname} Server by adding them to the classpath.

[IMPORTANT]
====
* {brandname} loads JAR files during startup only.
+
You should bring all nodes in the cluster down gracefully and make any JAR files available to each node before bringing the cluster back up.

* You should add custom JAR files to the `{server_home}/server/lib` directory only.
+
The `{server_home}/lib` directory is reserved for {brandname} JAR files.
====

.Procedure

. Stop {brandname} Server if it is running.
. Add JAR files to the `server/lib` directory, for example:
+
[source,options="nowrap",subs=attributes+]
----
├── server
│   └── lib
│       └── UserObjects.jar
