To summarize:
- custom-app was not marked as distributable, i.e., was missing
<distributable/> in its web.xml
- The clusterjsp sample app specifies "ha" instead of "replicated" as its
persistence type in sun-web.xml.
After adding <distributable/> to one, and changing "ha" to "replicated"
in the other app, memory replication has been enabled.
