When I try to use ‘HIbernate Mapping and Application Generation I’m consistenly getting errors. Error message on GUI is that ‘Internal error’ occured while generating artifacts. My set up is as follows:
jdk1.4.0.9
Eclipse 3.1.2
MyEclipse 4.1.1

Database is MSSQL Server 2005 Express
Driver from Microsoft: sqljdbc_1.0.809.102_enu.exe

Any idea what is happening?
Thanks,
Dave

Here isi a stack trace from errro log:

Can you paste the entire exception from the log file (<workspace dir>\.metadata\.log), near the bottom, for that might give us a hint on what happened?

Here is what I did:
1. I quit Eclipse
2. Cleared out the error log
3. Started Eclipse: got the first error message; Something about problems initilizing java tooling. (that’s the first stack trace
4. I run the reverse engineering and got the second error about generating artifacts (see second stack trace)

Any ideas?

The easiest thing to try first is to grab the jTDS driver and try that instead of the Microsoft one:
