Best Practices in Design
Hi everyone,
I have a question that deals with best practices and design. I have an
action class that does the work to get the customized information out of a
portlet. My question then is how should I get that information into the
jsp? Should I take that information and place it in the session so that the
jsp then looks for a particular attribute in the session? If I do that then
conceivably I couldn't have two portlets of the same type on the same page
because they would be using the same session variables to pass information
to the jsp.
To illustrate, let's say that I have a portlet that gets my sports links and
displays them. I want to reuse the same portlet to have a list of my
financial links. Is there anyway to get the action class to communicate
with the jsp so that two portlets and their action classes don't overwrite
the other portlet's data when they try and communicate with the jsp? Thanks
in advance.
Andy

For action-to-jsp, I use the following code:
In the action class:
public class foo extends JspPortletAction {
public static final String RET_SPECIAL_PREFIX = "foo-special-";
public void doCoolness(RunData rundata, Portlet portlet) {
String jspeid = portlet.getID();
rundata.getRequest().setAttribute(
RET_SPECIAL_PREFIX + jspeid, "Much Coolness");
}
In the jsp:
<%
String jspeid = (String) request.getAttribute("js_peid");
String coolName = foo.RET_SPECIAL_PREFIX + jspeid;
%>
<%= request.getAttribute(coolName) %>

I never tested but maybe you can try the following :
From the action class to the jsp, use the context. it should be
different for each portlet action.
From the jsp to the portlet action, try to add the portlet id into the
http request generated by your jsp page.
In the action class, check if the http request parameter which match to
this portlet id is equals to portlet.getId().
I'm not sure there is another way.

There are several examples of doing what you describe. Take a look at the
JSP Stock Quote portlet.
