Basically I was looking for a tool that is capable of making simple screens, with a built in workflow management. I saw the webinar of JBoss BPM Suite, it looks very lucrative to me.  I do have few questions,

1. I see via UI one could define the domain objects, but how it is stored ?  (Eg:- For the loan workflow, we create an Applicant object, is that getting stored in database in a tabled named "APPLICANT"  or similar ).
2. Is it possible to define complex domain object graph with multiplicity constraints ( eg: LoanApplication has-many Applicant, or LoanApplication has-one Broker)
3. I do have some legacy applications that needs data captured by BPM, can I pull that out via database directly ?
4. Can I apply customizations to the dashboard of "user" (the business user role), so that it will look more like my native application.
5. Is the source code of BMP suite open ?

Thank you.

Best regards,
