Not able to transform a message in Mule using TransformMessage component

I am not able to transform a message using a Transform message. My input is a java object which is as per wsdl and output is application/xml .

The Request is Object is of the form:

/**
 * PackagingRequest.java
 *
 * This file was auto-generated from WSDL
 * by the Apache Axis 1.4 Apr 22, 2006 (06:55:48 PDT) WSDL2Java emitter.

While I do this I get an error as Unexpected character 'p' (code 112) in prolog; expected '<' at [row,col {unknown-source}]: [1,1] (com.ctc.wstx.exc.WstxUnexpectedCharException)

And I notice the output of Transform message is com.mulesoft.weave.mule.WeaveMessageProcessor$WeaveOutputHandler@19e422ef and not an xml as expected but input is correctly RequestPackaging Object.

Can anybody please help?

The input xml is malformed. It doesn't start with < as stated in error. You need jaxb-to-xml-transformer Check out
