= Adding tasks to {brandname} Server deployments

Add your custom server task classes to {brandname} Server.

.Prerequisites

* Stop {brandname} Server if it is running.
+
{brandname} Server does not support runtime deployment of custom classes.

.Procedure

. Add a `META-INF/services/org.infinispan.tasks.ServerTask` file that contains
the fully qualified names of server tasks, for example:
+
[source]
----
example.HelloTask
----
+
. Package your server task implementation in a JAR file.
. Copy the JAR file to the `{server_home}/server/lib` directory of your {brandname} Server installation.
. Add your classes to the deserialization allow list in your {brandname}
configuration. Alternatively set the allow list using system properties.
