I am in a hurry right now so I will look further on your problem tommorow
morning. Meanwhile you may try to test your application via console instead
of in your IDE. If it works then you should add your jars in the classpath
of your project. Also the problem may have been caused by not inserting the
jars in the right place. Many IDEs have their own ANT_HOME. Elcipse's is in
plugins/ant-1.6/. Try to run ant from the command line, and also it would be
useful if you supply the stackTrace. We don't know which class isn't found.
Right?
Hope that helps...
