Updating a single jsp in two portlets

[Gaurav Sharma]

Hi,

I am using a single jsp (say abc.jsp) in two portlets displayed in a single page.
The requirement is like I have to introduce some HTML Text in one portlet. But if I change the jsp then the change is rendered in both portlets.

Please help me as how to introduce this change in one portlet so that the other portlet that is using the same jsp remains uneffected.

I will appreciate if anyone tell me that how to access a PortletSettings object in jsp

Kind Regards,
Gaurav

Try to keep the portlet related info Portlet scoped session instead of Application scoped Session.

As far as using PortletSettings, here's an example, including the appropriate deployment descriptors.

You can find a full multimedia tutorial that shows you how to code this portlet here:

Using The PortletConfig and PortletSettings Configuration Objects in a JSR168 Portlet

-Cameron McKenzie

  
The GenericTaxPortlet
package com.examscam.portlet;
 
import java.io.*;import javax.portlet.*;
 
public class GenericTaxPortlet extends GenericPortlet {
 
protected void doView(RenderRequest request, RenderResponse response)
throws PortletException, IOException {
 
response.setContentType("text/html");
PrintWriter out = response.getWriter();
PortletContext context = this.getPortletContext();
PortletConfig config = this.getPortletConfig();
 
String fedRate = context.getInitParameter("fedrate");
String regionName = context.getInitParameter("regionname");
 
String regionalRate = config.getInitParameter("regionalrate");
 

out.print("<BR>The federal tax rate is: " + fedRate);
out.print("<BR>The " + regionName + " tax rate is: ");
out.print(regionalRate);
 
}
}

Thanks a lot Cameron McKenzie!

I went through your Portlet multimedia.
It gave me somewhat clear seperation between absolute Portlets & Concrete Portlets.
I need some more simple Portlet tutorials(if possible then please provide me some more multimedia tutorials).

Regards,
Gaurav :-)
