[jboss-user] [Persistence, JBoss/CMP, Hibernate, Database] - No ManagedConnections in Hibernate

[mdrafimca]

Hi All,

I am using JBoss 5.0.1 GA. I am new to Struts and Hibernate, I have configured the hibernate with the datasource. The hibernate is able to fetch the data sometime and sometimes it is hanged up by throwing the exception which I have given below. 

Please help me how to solve this problem. 

I am using JBoss 5.0.1 along with Struts 2 and Hibernate 3.0.

19:18:17,250 ERROR [JDBCExceptionReporter] No ManagedConnections available within configured blocking timeout ( 30000 [ms] ); - nested throwable: (javax.resource.ResourceException: No ManagedConnections available within configured blocking timeout ( 30000 [ms] ))
