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.

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) {
%>
[input]
<% } else { %>
<%=c.toString()%>
<% } %>
