This code works in both jBoss and WebLogic. We had to extract the pool name
because WebLogic does not use java:/usswebPool like jBoss does. It just
uses just usswebPool ( Damn them ).
Connection getConnection() {
Connection conn = null;
try {
ussweb.system.System sys = new ussweb.system.System();
Context initCtx = new InitialContext();
javax.sql.DataSource ds =
(javax.sql.DataSource)initCtx.lookup(sys.getJNDIPoolName());
conn = ds.getConnection();
}
catch( NamingException n ) {
n.printStackTrace();
}
catch( Exception e ) {
e.printStackTrace();
}
return conn;
}
The following bit of code does not work and throws a ClassNotFoundException:
Connection getConnection() {
Connection conn = null;
try {
Class.forName( "org.jboss.minerva.datasource.PoolDriver");
conn = DriverManager.getConnection(
"jdbc:minerva:usswebPool" );
}
catch( Exception e ) {
e.printStackTrace();
}
return conn;
}
It never makes it to the driver manager code. The exception thrown is as
follows:

Okay, so far, so good. All the pools loaded successfully. Can
you now include the code you're using to open connections which is
failing, and the exception stack trace that is generated? Also, I really
thought WebLogic supported JNDI DataSources. Is that not true?
