-->
please disregard the tags...it was not gettin uploaded otherwise..
the wsdl associated with the ablove bpel process is as follows:

in the "binding.xml" generated after generate-artifacts, the style has been
changed to document/literal. the web-service involved also supports doc/lit format.
the bpel process gets deployed. using wsdl2Java, the client is generated. i get the
following error:
