could not find deserializer for type DataHandler (Version Problem 1.1 vs 1.2.1)

[Peter Koch]

hi folks,

I'm using apache axis with attachments (DataHandler).

Everything works fine using 1.1 both on client and server.


Now I migrated to 1.2.1.

When I run now the client using 1.2.1 and the server with 1.2.1 --> everything 
fine.

When I run the "old" client using 1.1 and the server with 1.2.1 I get in the 
client:

        org.xml.sax.SAXException: Deserializing parameter 
'getCmDbContentModsReturn':  could not find deserializer for type DataHandler


I've got many clients out there using 1.1 and I don't wont to / I can't (!!!) 
migrate all of them.

Whats the problem here ?

best regards,
peter
