}

This snippet of code is creating an Xml node which is then printed on to console.

Here's my problem now

If i use com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl;
I get dataNode as null which should not be the case.
And if i use org.apache.crimson.jaxp.DocumentBuilderFactoryImpl; (its commented in the code fragment shown above) i get the desired output.
Why????
Just for ur conveinence crimson.jar contains org.apache.crimson.jaxp.DocumentBuilderFactoryImpl whereas
com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl;
is in xerces.jar.
