Hi,
I'm having trouble getting the axis server to recognize the 
javax.activation.jar and getting the above error when deploying my service. 
I want to stream a file to a server using the DataHandler class so I've 
added the activation.jar to the Tomcat5.0\webapps\axis\WEB-INF\lib 
directory and when I run the axis happiness page it states that it has 
Found Activation API ( javax.activation.DataHandler )  at the right 
location. However when I try to deploy my wsdd file (with the 
activation.jar) in the classpath I get the above error, and the wsdl2java 
ignores the DataHandler parameter I've added to the method call.

It seems like some sort of classpath issue? But I have the activation.jar 
in the classpath when I'm running the wsdl2java cmd so any help would be 
much appreciated.

thanks,
Richard
