Hi All, I started using google app engine for java couple of days back. Am trying the hello world app as documented in page - http://code.google.com/appengine/docs/java/gettingstarted/creating.html, but running into issues.
I'm trying the ant build of the application, so created the build.xml file for my project as described in page - http://code.google.com/appengine/docs/java/tools/ant.html. My problem is - the datanucleusenhance target fails with a severe error message of classnotfound. The detail message is given below. Any idea what is going wrong in my test setup? I have also printed the classpath being used in the "enhance_war" macro. Really appreciate somebody's help here.
