I googled a lot and find the root cause that my xerces-j2-2.7.1.jar is 
not supporting this advanced document parsing. But I'm not able to k now 
that how can I change the value of
org.apache.xerces.jaxp.SAXParserImpl and which advanced jar file I 
needed to run this.

I find a solution but  don't know how to set this parameter in Java in 
Eclipse or through command line.

-Djavax.xml.parsers.DocumentBuilderFactory=com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl"


Following command shows that xerce.jar is in use.
$ ant -diagnostics
XML Parser information
-------------------------------------------
XML Parser : org.apache.xerces.jaxp.SAXParserImpl

XML Parser Location: /usr/share/java/xerces-j2-2.7.1.jar

Thanks for any help.

That's right.

The best action is get rid of that parser. Wherever it came from , there 
is a better one in Java6, so that JAR is unwanted.
