Hi Stanley,

It's hard to tell something useful without much information!

oracle.toplink.essentials.exceptions.DatabaseException Internal Exception: java.sql.SQLException: Failed to start database 'mydb', see the next exception for details. Error Code: 4000
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Please send "the next exception" message since it may contains a more detailed explanation of the error. Maybe this message is not on your console, but I'm sure you will find it somewhere (possibly in some "log" file). Did you have a stack trace that will help to narrow down the problem?

Otherwise, have you tried to open your DB with ij? I assume this will work since NetBeans is able to open the DB. Anyway, worth trying, at least to check the connexion URL and/or a possibly problem with your environment "shielded" by NetBeans...

I'm not sure this will help,
Sylvain

However, when I moved the database to Mac OS 10.5, the database can be opened by NetBeans IDE, yet my application can run but CANNOT connect to the database.

When the application runs to the point at JpaController class created, the following exception:

Exception [TOPLINK-4002] (Oracle TopLink Essentials - 2.0.1 (Build b09d-fcs (12/06/2007))): oracle.toplink.essentials.exceptions.DatabaseException Internal Exception: java.sql.SQLException: Failed to start database 'mydb', see the next exception for details. Error Code: 4000

What's wrong? Mac problem? Netbeans problem? JDBC problem? How can I solve?
