java.lang.ClassCastException
Thanks for the info Anthony (Posted by Anthony James on Tuesday, 03.27.07 @ 01:46am | #12754) I followed your comments and it resolved my problem. I also had to manually delete the class files from the war directory.  

very nice example
had to follow the steps mentioned in the comments though of manually deleting the files from the war folder and then running ant again to regenerate ear file. and for some reason the method name is starting with a capital letter..
