to get String[] back as what method returns:

 String[] datasourceNames;
 datasourceNames = (String[]) call.invoke( new Object[] { } );

to pass array in:

 String[] columnName = ...
 call.addParameter("columnName",
                        org.apache.axis.Constants.SOAP_ARRAY,
                        javax.xml.rpc.ParameterMode.IN);
and
 blat (Blat) = call.invoke(new Object[] { columnName } );
