Hi, I am using JBoss 4.2.2.GA on a HP Unix platform. For the sake of delegating connection management to the application server, I have started using connection pooling. The code I used was :
| InitialContext jndiCntx = new InitialContext(); | DataSource ds = (DataSource) jndiCntx.lookup("java:/testapi"); | Connection con = (Connection)ds.getConnection(); | But with this, I was unable to invoke any Oracle Stored Procedures that takes in an Oracle Object. I have resolved this issue by fetching the connection as : | InitialContext jndiCntx = new InitialContext(); | WrapperDataSource ds = (WrapperDataSource) jndiCntx.lookup | ("java:/clarityapi"); | org.jboss.resource.adapter.jdbc.WrappedConnection wrappedCon = (WrappedConnection) ds.getConnection(); | java.sql.Connection connection = wrappedCon.getUnderlyingConnection(); | Using this, I am able to send in any Oracle Objects by using StructDescriptor's and ArrayDescriptor's wherever necessary. Also, necessary validations were put in to check if the 'wrappedCon' is 'closed' and if so I was retrying for a maximum of 4 times to check for stale connections. However, the problem comes in when I am trying to close the connection. If i close it using : connection.close(); there is no problem. But in the next invocations of the : ds.getConnection() I receive the following exception : anonymous wrote : | [CachedConnectionManager] Closing a connection for you. Please close them yourself: org.jboss.resource.ada | pter.jdbc.wrappedconnect...@1c1ec0e | and the subsequent connections i receive have the following status : wrappedCon.isClosed : false wrappedCon.getUnderlyingConnection.isClosed() : true . So, the WrappedConnection object is not closed, but the underlying java.sql.Connection is closed. This "Closing a connection for you..." may be only a debug statement given for my benefit but even if I disable it, the fact is that the connection is getting closed when I wanted it to be just put back into the connection pool. The same scenario exists when I do : wrappedCon.close(); instead of connection.close(); Please suggest me a valid way to close these wrapped connections. I was under the impression that these close() methods would place it back into the connection pool, but probably with this output I think the JBoss connection pooling needs to be handled differently in my code. Thanks in advance.
