Parsing an XMl file using apache xerces parser

[satish satish]

When i try to parse An xml file i get following error .
Exception in thread "main" java.lang.NullPointerException
at org.apache.xerces.framework.XMLParser.parse(XMLParser.java:1094)
at javax.xml.parsers.SAXParser.parse(Unknown Source)
My Code goes something like this
InputSource is = new InputSource(new FileReader (arrGDCFolders[i] + DIR_DAT+arrGDCFiles[k]));
parser.parse(is , new UploadController().new MtnSAXParserHandler());
