    EL in included JSP

      Hi,

      Is it possible to enable processing of EL expressions in JSPs included with PortletRequestDispatcher?

       PortletContext context = getPortletContext();
 PortletRequestDispatcher rd = context
 .getRequestDispatcher("/hello.jsp");
 rd.include(request, response);


      Thanks,
      Konstantin

          Hi,

          I don't understand. Does it mean that your portlets with EL statements don't work in JBoss Portal? I work with 2.2.0-ALPHA and had no problems with it.

            I have JBoss Portal 2.0 release installed from "JBoss Portal + JBoss AS 4.0.2" bundle.

            I modified JBoss HelloWorld portlet to look like:

             public void doView(RenderRequest request, RenderResponse response) {
 response.setContentType("text/html");

 request.setAttribute("hello", "world");
 try {

 PortletContext context = getPortletContext();
 PortletRequestDispatcher rd = context
 .getRequestDispatcher("/hello.jsp");
 rd.include(request, response);
 } catch (Exception e) {
 e.printStackTrace();
 }
 }


            I am include this JSP file: 

            <h3>Hello World from JSP file!</h3>
1+1 = ${1+1}
<br/>
Hello attribute value: <b>${hello}</b>
<br/>



            Output looks like this:
            ---

            Hello World from JSP file!

            1+1 = ${1+1}

            Hello attribute value: ${hello}

            ContextPath: ${pageContext.request.contextPath}

            ---

            As you see EL expressions aren't evaluated. Is it only me who has this problem?

            Same file accessed from plain web application produces expected result.


            Thanks,

              Never mind. I solved the problem by inserting attribute version="2.4" for <web-app> tag in the web.xml
