Resolve myeclipse4.1.1 to a table generated mapping file, the "Generating artifacts" solution appears!

Many people have problems with "generating artifacts" when generating mapping files for a table with myeclipse4.1.1. I also encountered this problem, made me also very depressed!
After reading a lot of people's posts still can not be done. Finally, you find the following error message by looking at the. metadata\.log File:
! ENTRY org.eclipse.core.runtime 4 2 2006-11-06 17:08:56.78
! MESSAGE An internal error occurred during: "Generating artifacts".

It looks like the database driver was a disaster. My configuration is: eclipse3.1.2+myeclipse4.1.1+mysql5.0.12. The database driver is using the latest Mysql-connector-java-5.0.4-bin.jar. It's strange why such a problem still arises.
Finally, try to db-browser the configuration page schema datails at the time of connection to the Dispaly all schema and then connect, and the result can generate a mapping file for the table.
It looks strange, Alex.
I hope that when you encounter this problem, take a look at the Eclipse\workspace\.metadata.metadata\.log file, you can solve the problem according to the error prompt.
