Exception [TOPLINK-43] Error

Question

I'm trying to setup the Toplink JSP Demo from the examples for a week now and I'm getting the Toplink-43 error. I get this when I run the resetDatabase.sh. I know I can access the DB because the tables have been written, but I don't think the data has been inserted. Also I've been unable to get the sql output to be written out even with the value set to true.
"Missing Class for indicator field value"
[toplink:value-holder-indirection-policy] of type [class java.lang.String].
[java] Descriptor: XMLDescriptor (oracle.toplink.internal.indirection.IndirectionPolicy [DatabaseTable(indirection-policy)]
My java delvelpment guy hasn't been too much help with this, so I was wondering if someone here can offer some help. I can run the workbench.sh, but haven't pinpointed
what to change.
Thanks in advance.

Something is wrong with the mapping. Was it changed, or are you missing a step where you need to configure/map the project? It could be that you have a class indicator value in the class indicator field in the database that is not mapped. For example, if you've mapped "s" to be "SmallProject" and "l" to be "LargeProject", you may get an error like this if you accidentally had "q" in the database.
Here is what the docs say on this error:
Error code: 43
MISSING_CLASS_FOR_INDICATOR_FIELD_VALUE
Cause: OracleAS TopLink is missing the class for indicator field value
classFieldValue of type type. There was no class entry found in the
inheritance policy for the indicator field value that was read from the database.
It is likely that the method addClassIndicator(Class class, Object
typeValue) was not called for the field value. The class and typeValue is
stored in the hashtable, and later the class is extracted from the hashtable by
passing typeValue as a key. Because Integer(1) is not equivalent to
Float(1), this exception occurs when the type of typeValue is incorrectly
specified.
Action: Verify the descriptor.
