Java EE (Java Enterprise Edition) General Discussion

Like many people, I am trying to just read in the contents of a XML file. My code compiles in WS studio and I publish it to the server. However, I keep getting a ParserConfigurationException when I try to get a DocumentBuilder from the factory. Below is my code:

DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();

try {
DocumentBuilder builder = factory.newDocumentBuilder();
Document document = builder.parse( new File(XMLFILE) );
.
.
.

Any idea why?
