Customized Subscription Massage

Hello Kolegues,

i write a Workflow programm in java that uses the SAP Portal KM an with Java iViews as User-Frontend. It works fine and do what it should do. Every Workflowstep has its own Folder (sometimes with subfolders when many people responsible for this workflowstep and my programm must search for the right person) in the KM and the programm moves the data to the needed workflowstep. I use the SAP Portal User Management API for authorization and the subscription service for notification.

Now i want to add this feature:

The employe must get a customized Subscription Massage. I need for evry folder in the SAP Portal KM an Other subscription massage.

Is there a easy way to do this? In the moment i think i must write a new service an use Java-Mail. Is there a better way to do this?

Best regards,

Patrick Höfer
