I use the following code to get the connection:

InitialContext ic = new InitialContext();

            if(ic == null)
            {
                System.out.println("context not found");
            }

            DataSource ds =
(DataSource)ic.lookup("java:comp/env/jdbc/vhousehold");

            if(ds == null)
            {
                System.out.println("DataSource not found");
            }

            conn = ds.getConnection();

            stat = conn.createStatement();

            rs = stat.executeQuery("SELECT * FROM family_member ");
