Hello Bharath,

I am intrigued by the class not def found error
"gnu/classpath/Configuration"

Are you using a GNU JDK ?

You might want to use a Sun JDK. Ant uses normally the JDK pointed to by
the environment variable JAVA_HOME.

It is possible that there is a bug or limitation of ant and that ant
does not work with the GNU JDK.

Regards,

Antoine
