  1. Hi,
    Thanks for this excellent tutorial;However, There is something wrong in my case that prevents me from applying that tutorial and i wish if you can help. Actually, i have maven ear project which has 2 ejb modules and one of them is an ejb as web service, when i create a web service from the ejb i don’t have the option of “Bottom Up EJB web service” rather i have “Top Down EJB web service”, “Top Down Java Bean Web service” and “Buttom Up Java Bean Web service”. So, now i don’t know how to generate web service from my ejb?

    Do you have any idea how to solve that?
