Hi, I am having a application where I need to use resin-3.0.14 as a web server and jboss4.0.3SP1 as the application server. I am using stateless session bean's in EJB3. When I call a remote method on the EJB from the servlet I get the following exception in the servlet. I have deployed the same application on tomcat it works fine.

One returns a string and the other returns a object of type category which has two simple fields, name and description. The object is serializable and implements the serializable interface. The method which returns a string works fine. It gives the correct output. I am placing snippets of my session bean and servlet here. RewardsServlet protected void doPost(HttpServletRequest arg0, HttpServletResponse arg1) throws ServletException, IOException { | { | Context ctx = new InitialContext(); | rewardsEJB = (RewardsEJB)ctx.lookup(RewardsEJB.class.getName()); | String test = rewardsEJB.remoteMethod(); | System.out.println("Test is : " + test); | Category category = rewardsEJB.remoteCategory(); | System.out.println("Name is : " + category.getName()); | } RewardsEJB public String remoteMethod() { | return "Returned String from the remote method"; | } | | public Category remoteCategory() { | Category category = new Category(); | category.setName("Remote Test"); | category.setDescription("Remote Description"); | return category; | } | Can anyone help me out with this problem. Does it have to do anything with ejb3?
