Document auto-submit for approval

Dear all,

I am working on auto submitting a document for approval once added/changed from the KM content, I have the Java code for creating the repository service, I downloaded the SAP Netweaver Developer Studio, however I cannot add an RF component to the Portal Application Project (not found on the list)

Can someone help me out with this task? It's really urgent please.

Here is a screenshot of the Netweaver New -> Portal Application Object .. window

Please any help would be highly appreciated
