Name and version of the database you are using: Oracle 9i 9.2.0.1


I'm trying to use the Hibernate tools plug-in (12/12 build) and am trying to use the console. I've created a HIbernate Configuration but get the fetching children error. I've pointed to my hibernate.cfg.xml file and have set up the classpath to point to:

1. jar file with POJO classes in them
2. directory with the hbm.xml files in them
3. jar file with db driver (ojdbc14.jar)

If I remove #2 above I get the error stating that it can't find the first hbm.xml file referenced in my cfg.xml file. So, when I put that back I get the fetching children error. So I'm unsure which class files it can't find.

are you 100% sure you don't have some hibernate releated jars in that classpath of the console configuration ?

Yes - 100% sure. I do have the hibernate3.jar in my Projects properties which has to be there for me to run unit tests with hibernate. Can you turn up logging on the hibernate tools plug-in to see which class its looking for?

well it is a java vm error ;(

maybe enable classloading logs for the jdk to figure out what it is breaking on ?

i meant to say java *classloader* error.

...and the only thing createMappings do is to create a Mappings object which must work if the hibernate.jar is correct and not "duplicated" in the classpath.

So do you have any other suggestions? I did a fresh install of eclipse 3.1.1 because I had myeclipse installed and thought it might be conflicting with it. Same error. Does the jboss ide have better support? I had previously had the hibernate console running months ago with that.

no, this should just work.

Only way i can help is if you send me the mappings/classfiles that causes this behavior. And if you do, please minimize it to the smallest possible set ;)
