Subject Re: Execution error help - java.lang.NoClassDefFoundError
Date Sun, 07 Mar 2010 23:53:27 GMT
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
