I am trying to generate java code from a very simple mapping file, but fails.
As you see from the output from ant, it manage to find the Events.hbm.xml file (otherwise he wouldn't know about the mapping Event -> EVENTS)
but then he dies when he stumbles on the property id.

I have been sitting here for hours trying to figure out why it doesn't work (have tried numerous things without success).
My guess would be that my mapping file is not correct, but I cannot see any errors.

I am using the latest versions of hibernate and tools (downloaded yesterday)

I would be greatful for any help on this!

the output from ant:
Code:
$ ant
Buildfile: build.xml

codegen:

there is nothing wring w/ the mapping file, but it just doesn't have enough information for Hibernate by itself. For example, is 'id' an integer or a long?

Hibernate handles this by inferring this info from the .class file iteself. It is perfectly OK to deploy an app this way, but in your case, there is no Event.class file in the classpath.
