porting a single user app to RAP [message #653769]

I am converting an app that previously ran as a desktop app to RAP.
The existing code generally uses singletons that map one-to-one to a persistence context that is unique to each user.
So there might be something like a "CompanyManager" that persists to some file "John Smith.xml"

For the RAP app, I need to convert lots of objects that dont know about which user they are for to work in the RAP context.

I could create a new "CompanyManager" for each session but I would prefer to register the Objects as services.

Is there some strategy for enabling single-sourcing of back-end objects so they would work as RCP object, or POJOs and also be used in RAP?

(I am using JAAS to login to RAP, so it would be cool to leverage that credential to the back-end)

Thanks,
Tom

Hi Tom,

this might not entirely solve your problem, but here's an example how to
create session-unique instances of custom classes for RAP and RCP:

Hope this helps,
