Browse Roles, Folders, Pages & iViews assigned to a user: EP6 SP9 and higher

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.

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.
