How to set up code example....

Hi, I'm reading the "Portal Runtime Technology" guide and also looking at example code. I have questions on setting up the code in document "Custom Personalization Dialogs" (https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sapportals.km.docs/business_packages/a1-8-4/com.sap.pdk.tech.personalization.par.zip>)

On Netweaver, I created a new portal project, then I placed both source files(output.java and selectionScreen.java) under "src.api/(default package)". In my portalapp.xml, I included:

<b><property name="ClassName" value="selectionScreen" />

<property name="ClassName" value="output"/> </b>

I uploaded this par file to the portal and all it printed out was "Here are your selections null". Am I missing something?

Does anyone know another complete example of "Custom Personalization Dialogs" b/c in the end, I would like to create an edit page component so that users can edit other iView look and feel.

Any comments and suggestions are very appreciated!

Thanks so much for your time!

Baggett.
