converting from an old version of axis ?

[Christopher Snow]

I have some code which I think is written for an older version of axis.
How can I convert it to run with axis 1.2 ?

call.setMethodName( "processRequest" );
Vector params = new Vector();

// buffer[] is contains an XML document.
params.addElement( 
   new Parameter( "inputData", byte[].class, buffer, null ) );

params.addElement( 
   new Parameter( "sessionId", String.class, sessionId, null ) );

call.setParams( params );

Thanks in advance ...
