Hello List,

I recently installed Hibernate IDE tools for Eclipse. I setup JDBC connection and it was fine.

But while creating Hibernate Configuration File, after I click Next in the wizard, I am getting an exception.

I appreciate if someone could give some instructions to rectify it.

Thanks
Booshan.

Michel, Thanks for your reply. It helped a lot.

Hello List,

Now I am getting error while doing Hibernate Artifact Generation. Even though I have oracle driver in the classpath I am getting this error. The document asks to add the classpath while doing Console Configuration. But when I click add, there is no way I can select the Oracle jar. Appreiciate your help.

Thanks
Booshan

As per the docs your drivers need to be in some project managed by eclipse. External files is not yet supported - it will be in the future.

If your drivers are inside a project and you still can't select them then i would like to hear in more details on what and where they are since you can't select them - you should.

Thanks Max. That helped a bit.

While generating the Artifact, I got the following Out of Memory Error. I didn't find the trace though. I have 1GB of memory.

Thanks
Booshan

Error Jan 26, 2005 13:59:30.544 Error under artifact generation
java.lang.OutOfMemoryError

eclipse.buildId=I20041216-2000

hmm - haven't run into that my self either. (outofmemory errors doesn't normally provide stack traces - there isn't memory free ;)

What amount of memory have you told eclipse to use ?

Could it be that you are reverse engineering a complete database with *alot* of tables/columns ? You can limit that by setting the default schema/catagory in your hibernate.cfg.xml.

otherwise i would like to know if you could more into it and see what is causing you outofmemory.

When I had the JAR from postgres imported in he project , the console gave me this error
- error loading driverclass

In the console configuration it was not possible to select the jar, allthough it looked like it found something ( it automaticly had selected the org folder ).

Then I just copied the jar into one of the folders and selected that jar in the console configuration.

That seems to have solved this problem

Bastiaan

what was the difference between "having imported it" and "copying it into a folder" ?
