DataHandler - WSDL2Java

["Dorner, Thomas" <Th...@t-systems.com>]

Helo all,

I use Axis 1.2 RC2 for development. My Service have a method download which
looks like this:

public java.lang.String download(String request) throws
java.rmi.RemoteException {

      return invoke("download", request)

}

 

I use Jave2WSDL and WSDL2Java (my WSDL looks good!)

Why have WSDL2Java produce this download-Object and
downloadResponse-Object???????

Is this correct?????

 

I think there is no Serializing or deserializing nessecary for this method!

 

I also have a method updload which looks like this:

 

public java.lang.String upload(java.lang.String uploadRequest,
javax.activation.DataHandler uploadUploadData) throws
java.rmi.RemoteException {

return null;

}

 

 

The same procedure - why do I get a upload and download Object after using
WSDL2Java????

Okay, maybe the DataHandler can produce a Object - but why I don't get this
before.

I have thought AXIS Deserialize the Datahandler internally!

 

I attach my wsdl:
