Introduction
In this weblog i am going to present a Dynpage that display content assigned to a user in a nice htmlb tree display.
Jar files required
com.sap.portal.usermanagementapi.jar,com.sap.portal.pcd.glserviceapi.jar,com.sap.portal.pcmbuilderserviceapi.jar
Step1
Create a Dynpage project using NWDS or Eclipse wizard. Add the following source code to your
dynpage

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.
