19.9.3. Enable EJB 2.x Container-Managed Persistence
Container-Managed Persistence (CMP) is handled by the
org.jboss.as.cmp extension. CMP is enabled by default in the managed domain and standalone server full configurations, e.g. standalone-full.xml.
To enable CMP in a different configuration, add the
org.jboss.as.cmp module to the list of enabled extensions in the server configuration file.
<extensions>
<extension module="org.jboss.as.cmp"/>
</extensions>
To disable CMP in a server configuration, remove the extension entry for the
org.jboss.as.cmp module.
