JavaBeans in EJB App

Question

In which circumstances to use JavaBeans in Ejb application?
I have created a simple e-commerce application using EJB components but without JavaBeans at all.
The thing is that i have a problem with the jsp page which presents all the products under a particular category, (each product has a link to add it to the shopping cart of the user).
After the user select a category, a servlet getting the products list from a session ejb and put the result as an attribute in the request. Then i'm prining all the products - till here no problem.
In order to add a product to the shopping cart i'm sending to a servlet some info about the product , but this info sometimes contains a special characters , so i decided to use <c:url> with <c:param> for the attributes.
     <%
      java.util.List<Entity.Products> products=(java.util.List<Entity.Products>)request.getAttribute("products");
       for(Entity.Products product : products)
        %>
<c:url value="ShoppingCartServlet" var="productUrl">
      <c:param name="productId" value="" />
      <c:param name="productName" value=""/>
  </c:url>
  <A href="${productUrl}">Add</A>now how can i set the values of the params?
i can't use scripting elements (<%=%>) , it is not allowed.
Do i need to use JavaBeans?
Thanks in advanced.

Answer 1

is it so hard? Looky here:
; hostname: 127.0.0.1; port: 3820"The application is trying to connect to the localhost, and the glassfish server is not running on the localhost. The JNDI properties of the application must point to the actual host that the glassfish server is running on.
