Axis 1.4 - DataHandler: second param is null

["Babette Wagner (s713474)" <b....@tfh-berlin.de>]

I'm using Axis-1_4 with apache-tomcat-5.5.20 and JDK 1.5.0_08

With wsdl2java I've generated skeleton/stub/impl for two different methods. 
Both have DataHandler as return type and one or two DataHandlers as input params. 

The method which has two input params doesn't work properly because the second
argument is null, even if it is visible in the soap request that follows:

If I do a remote debugging it becomes obvious, that param in1 is null.

Any ideas?

regards,
Babette
