Introduction
In this weblog i am going to present a Dynpage that display content assigned to a user in a nice htmlb tree display. This code is for portal version EP6 SP9 or higher.
Jar files required
com.sap.portal.usermanagementapi.jar,com.sap.portal.pcd.glserviceapi.jar
Step1
Create a Dynpage project using NWDS or Eclipse wizard. Add the following source code to your
dynpage
component.package com.ust.browserole;

Step2
Step 3
Save the following images and add it to your
dist->images
folder.
Step 4
Deploy your application in your portal. h5. BAM! you got yourself a nice utility iView that display all the content assigned to a user.
