Hi I m getting this error with JBoss4.2 environment when I am trying to use jdbc connection pool. This connection data source object is being retrieving from the entity beans. EJB 2.0 anonymous wrote : Along this excepiton there one exception with related connection is Closing a connection for you. Please close them yourself: org.jb oss.resource.adapter.jdbc.WrappedConnection@1dd66fd The same code is working fine with WAS5.1 and Weblogic9.1 servers. anonymous wrote : Once more things is that after retrieving connection from the pool, there is stored procedure call execution. I donot know why the connection is getting closed. Is there any issue with executing stored proc with jboss or any thing else?
