xml-xml transformation exception

When I am trying to transform a xml to another xml via xslt in Weblogic8.1 with default transformer available, I am getting following exception.

; Line#: -1; Column#: -1
javax.xml.transform.TransformerException: Premature end of file.

Here is the code for transformer:

Source inputXML= new StreamSource(in);
Source inputXSL = new StreamSource(Thread.currentThread().getContextClassLoader().getResourceAsStream("DDCCommonDataEbridge.xslt"));
TransformerFactory tFact = TransformerFactory.newInstance();

Transformer tf = tFact.newTransformer(inputXSL);

Result result = new StreamResult(new BufferedOutputStream(new FileOutputStream(new File("test.xml"))));

tf.transform(inputXML,result);

Moreover I have tried to implement inbuilt xlan processor with weblogic8.1
I got the following exception;
java.lang.ClassCastException

Here is the code:
XSLTInputSource source = new XSLTInputSource(in);

XSLTInputSource stylesheet= new XSLTInputSource(Thread.currentThread().getContextClassLoader().getResourceAsStream("DDCCommonDataEbridge.xslt"));
//System.out.println("test:"+stylesheet.getCharacterStream().read());

XSLTResultTarget target = new XSLTResultTarget(System.out);

And at the following line ClassCastException arises.

processor.process(source, stylesheet,target);

I have identified the problem: before transformation, I used to pass inputstream object to SAXParser, so it was convert inputstream in SAX format, and during transformation I have coded by considering as common inputstream and that is where the problem is.

Now 1 more query: Is there any way of converting SAXResult object to inputstream object or XMLBeans object.
