Hi Manish,
AFAIK, WSRP4J doesn't come with an own implementation of neither a
servlet container nor a portlet container. So the servlet container
should be the same for local and remote (i.e. deployment on the WSRP
producer) portlet deployment. I'm using Pluto 1.0.1 as portlet
container which in turn is deployed on a Tomcat 5.5.16 servlet
container.
Since I'm able to set the session attribute on locally deployed
portlets, it should also be possible to do so for portlets deployed on
the WSRP producer.
Regards,
Kevin

Hi Kevin,
Is the vendor/version of servlet container is same for local and remote
portlet deployment?? The PortletSession implementation actually uses
ServletSession to store any attribute. Some Servlet container allows any
non-serializable attribute to be set in the session and some doesn't. I
believe, in your case, either the servlet container vendor or its version is
different for local and remote deployment.

Manish.

Hi!
I'm developping a portlet and I want to use the PortletSession to pass
attributes between the Portlet and a JSP. This works perfectly when I
deploy the portlet locally (Pluto), but it doesn't when I access the
portlet through WSRP using WSRP4J (with Pluto) as producer.
Here's what I'm doing exactly:
1. invoke an actionURL in the JSP
2. processAction in the portlet will be called
3. set PortletSession attribute (the attribute is an object of MyClass)
actionRequest.getPortletSession().setAttribute("myClass", new MyClass());
4. get MyClass object in JSP
<%
MyClass c = (MyClass)
renderRequest.getPortletSession().getAttribute("myClass");
%>
5. display c.toString
<% if (c != null) { %> <%=c.toString()%> <% } %>
It does work if the portlet is local but not when I consume it
remotely. That's why I assume it must have something to do with the
WSRP4J producer implementation. I don't get any error messages neither
on the consumer nor on the producer.
It is strange tough that if I use a String or an Integer object
instead of MyClass it even works with WSRP4J!
Any help would be appreciated,
Kevin
Here the code of the portlet:
public class SessionTestPortlet extends GenericPortlet {
public void doView(RenderRequest request, RenderResponse response)
throws PortletException, IOException {
PortletContext context = getPortletContext();
PortletRequestDispatcher disp = context.getRequestDispatcher("/jsp/"
+ "view.jsp");
disp.include(request, response);
}
public void processAction(ActionRequest actionRequest,
ActionResponse actionResponse) throws PortletException,
java.io.IOException {
actionRequest.getPortletSession()
.setAttribute("myClass", new MyClass());
}
}
Here the code of view.jsp:
<%@ page session="true"%>
<%@ taglib uri="http://java.sun.com/portlet"; prefix="portlet"%>
<%@ page import="javax.portlet.*"%>
<%@ page import="java.util.*"%>
<%@ page import="session.test.portlet.MyClass"%>
<%
MyClass c = (MyClass)
renderRequest.getPortletSession().getAttribute("myClass");
%>
<%
if (c == null) {
%>
<% } else { %>
<%=c.toString()%>
<% } %>
