what database are you using?
We were using ,
clustered-hsqldb-persistence-service.xml. I think that was the problem.After changing it to mysql db , mysql-persistence-service.xml.It started working fine.
In any case we can use clustered-hsqldb-persistence-service.xml for clustered environment ? if not then why we have it we already have hsqldb-persistence-service.xml file.
Awaiting for positive reply
hsql is not a clusterable database.
I think that is made clear in the installation section of the user guide.
The naming of "clustered-hsql-persistence-service.xml" is admittedly confusing, but it's only intended as a placeholder.
As I say, the installation guide is explicit about not to use hsql.
