Error message by Execute the Transfer Package in BC 4.6

Hello,

we plan to migrate our old Business Connector 4.6 to Business Connector 4.8.

We implement the Transfer.zip package successful in the BC 4.6.

Unfortunately we get follow Error Message back, if we try follow link in the Explorer: http://:/Transfer/

Error:

java.lang.reflect.InvocationTargetException:
com.wm.app.b2b.server.ServiceException: method
(Ljava/lang/Exception;)V not found

It will be very kindly, if you give us a solution, whats going wrong.

Kind regards
