Java EE (Java Enterprise Edition) General Discussion

Hi,
I am running JAXB 1.0 (JWSDP 1.1) with Weblogic 6.1 Below is the code that is causing the exception. Inspite of the error JAXB reads the XML in fine and everything proceeds normally. Any help would be greatly appreciated.
Thanks in advance,
Abhijit

------------------------------------------------------
JAXBContext jc = JAXBContext.newInstance("my.package");

// create an Unmarshaller
Unmarshaller u = jc.createUnmarshaller();

// enable validation
u.setValidating( true );

// unmarshal an instance document into a tree of Java content
ProductsType prods = (ProductsType)u.unmarshal(new FileInputStream( "products.xml" ) );


The last line above causes the following error
