Hi,

we recently migrated from Jboss 4 to Jboss 6.2 and made all related changes.

Since we migrated we have seen this issue of the connections getting spawned again and again.Beow is the error trace from the Jboss logs.

This has become very frequent now:

JBWEB000236: Servlet.service() for servlet jsp threw exception: java.lang.NullPointerException

java.sql.SQLException: javax.resource.ResourceException: IJ000453: Unable to get managed connection for java:/jdbcDS/OracleELAPP

13:30:08,644 ERROR [stderr] (ajp-/156.30.10.248:8019-37)      at org.jboss.jca.adapters.jdbc.WrapperDataSource.getConnection(WrapperDataSource.java:151)

…..

Caused by: javax.resource.ResourceException: IJ000655: No managed connections available within configured blocking timeout (5000 [ms])

…..

Can you please help.

thanks,Sai
