Connection closed

[Cristian Popovici]

Hello,

I am using JPA on sun app server with toplink as the persistence layer. I am using a session bean to load some data in the database Everything works fine, but from time to time the connection to the database is closed and I get this exception:

System Exception
javax.resource.spi.LocalTransactionException: Connection.close() has already been called. Invalid operation in this state.
at com.sun.gjc.spi.LocalTransaction.begin(LocalTransaction.java:63)
at com.sun.enterprise.resource.ConnectorXAResource.getResourceHandle(ConnectorXAResource.java:215)

at com.sun.enterprise.resource.SystemResourceManagerImpl.enlistResource(SystemResourceManagerImpl.java:87)    

Any ideas? Thanks.
Cris.

Cristian,

Could this be a problem with the Glassfish connection pooling? You might want to post on the Glassfish forum in any case.
