Few important points when trying to run this code from Jdeveloper

Make sure you are importing the following jar files in the project library path

ant-launcher.jar,Ant.jar,XercesImpl.jar,Ant-contrib-1.0b3.jar



These jars can be located in the following directory

JDEV_HOME\modules\org.apache.ant_1.7.1\lib

If you will not import all the jar files you may get following errors

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/tools/ant/launch/AntMain

So make sure you are importing the jar files from your own jdev home from the path specified.
