Could not type cast in java embedding

Question

DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
org.xml.sax.InputSource in = (org.xml.sax.InputSource) getVariableData("Invoke_1_getRoutingAndFrameJumpers_OutputVariable","getRoutingAndFrameJumpersResponse");
Document doc = db.parse(in);
In the above code I am trying to type cast the variable getRoutingAndFrameJumpersResponse into org.xml.sax.InputSource so that i can parse.
I am not getting any error during compilation
but I am unable to type cast some run time error is coming in the line were I am type casting but I am not able to see the runtime error.
How can I see the runtime error in java embedding, how to type cast a variable into xml so that I can parse it.

Hi Arun,
Could you try using the bpelx:rename extension in an assign activity enables a BPEL process to rename an element through use of XSD type casting.
<bpel:assign>
<bpelx:rename elementTo="QName1"? typeCastTo="QName2"?>
<bpelx:target variable="ncname" part="ncname"? query="xpath_str" />
</bpelx:rename>
</bpel:assign>
Cheers
