Wrapper connection for jboss exception

Question

Hi
The url below says how to extract a Oracle type Connection from JBOSS Wrapper
"http://forums.oracle.com/forums/thread.jspa?messageID=1384788 "
No problem is getting the connection, but Do Not know hoe to close the same for the obtained
connection to be returned
Exception : "CAN'T CLOSE CONNECTION FOR POOL " is thrown ?
The code is as given below
* To get a connection
private WrappedConnection WCP = null;
public synchronized Connection getConnection() {
Connection conn = null;
OracleConnection connection;
try {
WCP = (WrappedConnection) ODS.getConnection();
connection = (OracleConnection) WCP.getUnderlyingConnection();
} catch (SQLException sqlex) {
System.out.println("<<<<<<<<<<< NO CONNECTION>>>>>>>>>>>>");
//sqlex.printStackTrace();
return conn;
* Return the Connection to Connectioon pool
public synchronized void freeConnection(Connection con) throws Exception {
System.out.println("RELEASING THE USED CONNECTION TO POOL");
try {
con.close();
}catch (Exception ex) {
System.out.println("CAN'T CLOSE CONNECTION FOR POOL ");
ex.printStackTrace();
Any help would be appreciated

Answer 1

Well, it would be good if you showed us what exception was printed out when
you failed to close 'con'... Also, your getConnection() seems to return an unset
variable, not what you unwrapped.... And if you put the WCP variable in the
method, it won't have to be synchronized...
