Hi Bodhi,
Thank you so much. If Pollix has MySQL, I definitely vote to use it as a software developer CD.
To use MySQL on Linux, one can run like this
- Start MySQL server by using console as root, run "mysqld", or run "sudo mysqld"
- Start MySQL client by using console, run "mysql". The schema one sees in the database will depend on the user privillege.

However, JBoss on Polix is on the CD, so the "deploy" directory of JBoss is on the CD, and I can not deploy J2EE WAR files or EAR files in JBoss.
If I copy JBoss to hard disk, it will have a lot of error with registering JMX beans and JMS when I start it from the hard disk. I don't have those problems if I run it from the CD (then I can not deploy apps) or run it from Window XP (which I don't like).

Do you have any suggestion ?

Thank you,
Linh.
