Java Database Connectivity (JDBC)

I am having a problem while using savepoints where after I have committed a transaction, the specific table that I am updating still has an exclusive lock on the table.

The only way I have seen so far to fix this is to either not use the savepoint (not a great idea) or call a different function that performs a simple DB query (a worse idea). Its almost like I have a nested transaction but I'm not sure why that's the case. I have run traces using a profiler to see what is working and what is not. That's where I see an extra "Commit" operation when I do a subsequent call on a different connection that commits the previous transaction.

My code looks like many of the examples on the web.

InitialContext ic = new InitialContext();
DataSource ds = (DataSource) ic.lookup("java:/myDB");
conn = ds.getConnection();

conn.setAutoCommit(false);
savept = conn.setSavepoint( "SAVEPOINT");

// execute sql statement

if( success )
{
conn.commit();
}
else
{
conn.rollback(savept);
}

Does anybody have an ideas as to what I'm doing wrong?

Thanks,
