This question has been checked for most of the day, to make a few points:

1. JDBC Configuration Error

2, the user password is not correct

3. Check the Oracle error log, not very good view

4, the Oracle driver version is not correct

Each of the above has been verified, or not, and then restarted the next eclipse, OK.

The final confirmation is that the Oracle driver version is incorrect

Why the restart to take effect, the problem has not been understood, who knows to tell.

Summarize:

The error message indicates that the problem is in the JDBC Oracle package, no catch, leading to the wrong direction, white busy.
