Glassfish JDBC：我只需要使用jdbc / __ default吗？

Question

I try to use Glassfish/MySQL. I have created JDBC resource and JDBC connection pool for MySQL.

But if I tried to put MySQL JDBC resource in jta-data-source, nothing works.

Then if I tried to modify jdbc/__default and change its connection pool from DerbyPool to MySQL, it works. My entity gets persists to the correct table.

So do I have to use jdbc/__default only as my JDBC resource for my app? How can I use the JDBC resource and JDBC connection pool I created in my app?

I really have hard time understanding how to use JDBC in Glassfish.

This is my first time to ask question in this forum. Thank you very much.
