I am new to jbpm and i have to design a workflow that inteacts with some of the existing services.I have a scenario like this:There is a service called as Registration which has its own UI and the database.I need to connect to the Registration service(whenever a new user needs to be registered) from the workflow and get the info of this user from the database.can i enter the user details using the workflow so that using this i can connect to the external service(and the databse)?Any help in this regard is highly appreciated.
The documenation usually helps.
Check the docs for a sectionc called Domain Specific Processes or search for "Work Item", that concept will allow you to implement pretty quickly any communication with an external system.
Cheers
