Explains how to configure the cache invalidation bridge.
To pair two beans you need to assign them to same invalidation group.
This is done in jboss.xml
<entity>
<ejb-name>whatever</ejb-name>
<configuration-name>Standard CMP 2.x with
cache-invalidation</configuration-name>
<!-- Set to False on the read/write bean -->
<cache-invalidation>True</cache-invalidation>
<cache-invalidation-config>
<invalidation-group-name>yourname</invalidation-group-name>
</cache-invalidation-config>
See docs/dtd/jboss_3_2.dtd for more explanation.
Once you have the invalidatable cache configuration (above),
you can also use JMX to invalidate specific primary keys.
