Well...looks like the attachment didn't work!
Test case attached again here:
http://n2.nabble.com/file/n661801/openjpatest.zip openjpatest.zip
The problem I am facing looks like the open JIRA
https://issues.apache.org/jira/browse/OPENJPA-291. The symptoms are same.

Hi,
1. You do need to configure both sender and receiver side. But there is no
extra configuration other than 'openjpa.RemoteCommitProvider' settings.
2. Please check that the port where sender sends matches the port where
the receiver listens to.
3. Please post persistence.xml used by both
Hi,

Almost ALWAYS. Unless you really, seriously do not want it, force removal by
FetchPlan.removeFetchGroup(FetchGroup.NAME_DEFAULT);
