Java classes that implement Comparable don't work in DB2?

[Malte Finsterwalder]

Hi there,

is it correct, that classes that implement the Comparable interface
don't work inside DB2? I tried to create an object and send it to a
client (serialized). But the object implements Comparable. When I
create the object inside a java transform function I get an error:
-------------------------
ErrorCode: -4302; SQLState: 38501
COM.ibm.db2.jdbc.DB2Exception: [IBM][CLI Driver][DB2/NT] SQL4302N

In db2diag.log I get:

Is this a DB2 sortcumming or bug?

Malte,

do you have a small example that you can send me?

I don't think that implementing interfaces should make a difference.
