Apache Soap to Axis (beginner)

[Shrotriya, Sumit]

I am converting some code from Apache Soap to Apache Axis. 
 I want to set two parameters in my service call..
In the soap version of the code it was like this::

  //params.addElement(new Parameter("servicename", String.class,
varServicename, null));
  //params.addElement(new Parameter("input",
javax.activation.DataHandler.class, dh, null));
  //call.setParams(params);

Could you please help me as how should I pass the DataHandler as a parameter
in axis.
Regards,
Sumit
