Hi Abe,
Thanks, that worked.
Why is it not able to load
com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl.class
which is actually present in jre/lib/rt.jar? Is this a known bug in
maven or ant? If yes, what's the bug number?
Thanks,
Sahoo

Hi Sahoo,
I had a similar problem.
There are the dependecies that I had to provide to get rid of those
exceptions:
<dependency>
<groupId>xerces</groupId>
<artifactId>xercesImpl</artifactId>
<version>2.8.0</version>
</dependency>
<dependency>
<groupId>jdom</groupId>
<artifactId>jdom</artifactId>
<version>1.0</version>
</dependency>
<dependency>
<groupId>xml-apis</groupId>
<artifactId>xml-apis</artifactId>
<version>2.0.2</version>
</dependency>
Also clean out your repository after adding these dependencies (delete
the xerces, xml-apis, and jdom directories in your .m2 repository).
Let me know if this works for you.
Regards,
Abe

Hi,
I get /javax.xml.parsers.FactoryConfigurationError: Provider
com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl
could
not be instantiated: java.lang.NullPointerException/ when I call
an Ant
script from maven using maven-antrun-plugin. I have tried using
fork =
true as well as false, but same result. Maven version is 2.0.7 and JDK
version is 1.5.0_06. I don't understand why Ant is not finding this
class, which is actually present in jre/lib/rt.jar. I get the
following
output while running with -X option:
[INFO] [antrun:run {execution: default}]
