I will need to design an EBF process which will deal with various stages of performing an action. The EBF will be a BPEL instance.
Users will need to be able to log into the frontend application and be able to see what change the process has reached.
To do this I will need a service which queries the state of the EBF. The service will need to call in to an already running BPEL process to find out what stage it is at (possibly by reading a variable).
I can’t find any documentation regarding how to design this. Does anyone know if there are any?
you can design your BPEL process to accept a status-request message that may arrive in parallel to the primary business logic flow. However please be aware that only a de-hydrated process The design is documented in the wiki page given below. Please go through the Impacts and Assumption sections to make sure that it suits your requirements.
