• Add treecache.xml (you can find it into the seam blog example) to /resources/META-INF/
• Open build.xml for editing, go to the “ear” target and tell to copy the treecache.xml file:
  <target name=”ear” description=”Build the EAR structure in a staging directory”>
  …
      <copy todir=”${ear.dir}/META-INF”>
          <fileset dir=”${basedir}/resources/META-INF”>
              <include name=”application.xml”/>
              <include name=”jboss-app.xml”/>
              <include name=”seam-deployment.properties”/>
              <include name=”treecache.xml”/>
          </fileset>
      </copy>
  </target>
• Edit components.xml, add the following XMLNS:
  xmlns:cache=”http://jboss.com/products/seam/cache”The following schema location:
  http://jboss.com/products/seam/cache http://jboss.com/products/seam/cache-2.1.xsd 

  And the following declaration:
  <cache:jboss-cache-provider configuration=”META-INF/treecache.xml” />

• Edit deployed-jars-ear.list and add the required JARs, I used the JBoss Cache 1.x for JBoss AS 4.2.X:
  jboss-cache.jar
  jgroups.jarHere there is the list of jars (and versions) for other configurations.

And here you find the way how to use it in your projects.

Hope you liked it.
