Before you can verify the datasource configuration, Oracle XE should be reconfigured to avoid port conflict with JBossAS as by default they both start a web server on port 8080.

Open up an Oracle SQLcommand line and execute the following commands:

SQL> connect; Enter user-name: SYSTEM Enter password:
Connected.
SQL> begin 2 dbms_xdb.sethttpport('8090'); 3 end; 4 /
PL/SQL procedure successfully completed.
SQL> select dbms_xdb.gethttpport from dual;
GETHTTPPORT
-----------
8090	

The web server started by Oracle XE to provide http-based administration tools is now running on port 8090. Start the JBossAS server instance as you would normally do. You are now ready to use the test client described in Chapter 6.5 to verify the proper installation of your datasource.
