java.lang.ClassCastException Error
Hi,
It would be great if anyone can help. I am trying to build a stateless session bean with DAO and a servlet accessing the session bean, compilation, packaging and deployment is working fine, but when I am hitting the url for the servlet I am getting the following error. Please let me know if you need any additional files. I will definately post it.
