[castor-dev] Problem with complex identity field.

[Jesse Greenwald]

In my mapping (see attached file) I have a class
"org.dharma.job.TaskWrapper" that has 2 items in it's identity field. 
One of the items points to a field that is of type "integer".  The other
item points to a field that is of type "org.dharma.job.JobWrapper". 
When I try to create a job with a task, JDO throws the following
exception:

Exception in thread "main" No class found for org.dharma.job.JobWrapper.

        at org.dharma.middleware.TestJDO.<init>(TestJDO.java:73)
        at org.dharma.middleware.TestJDO.main(TestJDO.java:36)

Is it not possible to have a complex identity field like that, or am I
doing something else wrong?

Thanks
