jBPM gives you flexibility to hook in your custom code to do whatever you want to e.g sending mails, interacting with other applications etc .....
I hope you shouldn't have any problems in implementing your requirements.
If you encounter any, post it in this forum.
Thanks anurag for your prompt reply.
Does it means jBPM provide us some kind of interfaces to receive data from other applications and also In our existing applications we need to create new interfaces to interact with jBPM?
Thanks in advance.
is there any tutorial/example available for this ?
Thanks for your help.
yes, in the jBPM source are examples (e.g. the webapp), testcases etc... The docs are also good to read.
