Deserialization error due to Server handler-plz help URGENT

[jeong jim <je...@yahoo.com>]

Hi,
i am using wstk3.2.I deployed a server side handler which changes the SOAP envelope.I am getting the SOAP envelope from message context and writing it to a file.Then i am reading the same file and setting it as new SOAP envelope.
when i try to call the service(which accepts a java bean as input parameter) it gives me an error something related to deserialization.If i remove the handler it is working fine with my bean as input parameter.

please help me.I am in aurgent situation stuck up with this.

here are the code and error log
*******************
Message requestMessage = msgContext.getRequestMessage();
SOAPEnvelope PreEnvelope = requestMessage.getSOAPEnvelope();
Document doc = getSOAPEnvelopeAsDocument(PreEnvelope,msgContext);
output(doc);
SOAPEnvelope PostEnvelope = new SOAPEnvelope( new FileInputStream("file1.xml"));
requestMessage = new Message(PostEnvelope);
msgContext.setCurrentMessage(requestMessage);
*****************
error log:
*******************
