I'm using Hibernate 3.0.5 and am trying out the Eclipse (3.1) tools (3.1 alpha 5). Yes, I know it's an alpha release, but I'd love to test it out. I'm receiving the following error when trying to expand the tree in the Hibernate configuration pane:

An internal error occurred during: "Fetching children of resolve".
java.lang.NullPointerException
at org.hibernate.console.ConsoleConfiguration.buildWith(ConsoleConfiguration.java:123)
at org.hibernate.console.ConsoleConfiguration.build(ConsoleConfiguration.java:107)

at org.eclipse.ui.progress.DeferredTreeContentManager$1.run(DeferredTreeContentManager.java:192)
at org.eclipse.core.internal.jobs.Worker.run(Worker.java:76)



eclipse.buildId=I20050627-1435
java.version=1.5.0
java.vendor=Sun Microsystems Inc.
BootLoader constants: OS=win32, ARCH=x86, WS=win32, NL=en_US
Command-line arguments: -os win32 -ws win32 -arch x86 -clean

I didn't find any information in the FAQ or a forum search; nothing immediately obvious via Google, either. Any suggestions?

I get the same NPE when I give in the Console Configuration wizard as configuration file the hibernate.cfg.xml and in Mapping file the *.hbm.xml . I haven't found yet what's wrong.

if you could send me a screenshot of how your console configuraiton and hibernate.cfg.xml looks like it would be helpfull.

My mistake was not to give the path to jdbc.jar in the classpath window. Adding it caused the NPE to disappear. Now I get

Code:
org.hibernate.MappingException: Resource: opus11/mat/Matemaatikko.hbm.xml not found
   at org.hibernate.cfg.Configuration.addResource(Configuration.java:465)
   at org.hibernate.cfg.Configuration.parseMappingElement(Configuration.java:1404)

   at org.eclipse.ui.progress.DeferredTreeContentManager$1.run(DeferredTreeContentManager.java:192)
   at org.eclipse.core.internal.jobs.Worker.run(Worker.java:76)


and when I add the path to Matemaatikko.hbm.xml I get:

Code:
org.hibernate.MappingException: Could not read mapping document from file: C:\Porasto\opusEJB\build\opus11\mat\Matemaatikko.hbm.xml

   ... 8 more

ahh .... it shouldnt fail with a NPE in that case...fixed in cvs AFAIK.

The others you get a quite "natural"

The first one is becase you didn't have the pojo's in the classpath and the other is because you have added the mappings to both hibernate.cfg.xml and the mappings list.

So I give the path to the mapping file *.hbm.xml either in the Mapping files window or in the hibernate.cfg.xml, not in both. But without <mapping> element the hibernate.cfg.xml is not valid! I removed it from Mapping files window. It solved the problem. Thanks for the help!

eh - <mapping> is not required in cfg.xml and haven't been for a long time (even in H2.1.somerelease)

And yes, you only specify it once like you would normally do in hibernate - and if you already have a good hibernate.cfg.xml no need to add it to the mappings list also.

Good! I don't have to write a separate cfg.xml for the Hibernate Console. I can use the same pair of hibernate.cfg.xml and hibernate.properties as normally.

yes - only requirement at the moment is that if want the tool to contact the database the connectionmanager must be able to get an connection (which makes datasource connectionmanager defunct in this case)

Still I fail to open the all-important HQL Editor view ... the Configuration and Session factory are created without errors.
