Null SAXParser while creating getXmlReader() in Digeter class

[Viswanath ar]

Hi All,

I am trying to read an xml file and it gives me the following error :

java.lang.NullPointerException
at org.apache.commons.digester.Digester.getXMLReader(Digester.java:1058)

When I checked the Digester API, I understand that getParser() is returning null. Looks like it's unable to find SAXParser. I have xerces.jar in the classpath, but have no idea why it's not finding it.
Appreciate your valuable inputs in Advance...
