NoClassDefFoundError when deploying webservice calling BAPI

Hi,

I need to develop a java webservice which is calling a BAPI. I use DCs for that. One DC contains the JARs (JCO, ...) the other one my class which calls the BAPI (I generated the proxy classes in the same DC).

Everything looks fine but when I deploy my webservice I always get a NoClassDefFoundError for BAPI_..._Input. Can you tell me why it's not working and what is a solution for it? Honestly I don't understand why I get this error, as the BAPI_...Input is in the same DC.

Thanks a lot in advance.

Kind regards,

Timo
