Hi Niraw.

Two parts of an answer: Yes, it is possible. jBPM can handle even big byte arrays (files). But: It is not a good practice. Normally it makes more sense, to store the file somewhere (in you CMS, FTP or whatever) and just pass on an id/path/…

In most situations it is not advisable to store too much data in the process, better just store keys. But technically it would be possible.

Bernd.

This concept is very good, but is it really possible to store content of file in process variables?

What happen if file size is to big?

I just wanted to inform everybody: The shown example doesn’t run on the current ESB versions, since the SignalCommand isn’t any longer supported and was removed. This was done, because by just using a Signal you do not check if the process instance is still in the right state.

To do such kind of things you have to use the JbpmCallback, which operates on data, provided in the ESB message header. This information is written there by the EsbActionHandler if you call the ESB via jbpm.

if you have other requirements you are a bit out of luck here. This is, why I think the current correlation mechanism is too limited. But let’s see what imprrovements we can make here in future (so if you have use cases which doesn’t fit, please report them to the ESB forum so we can make up our minds for a good solution there).

Cheers and have fun
Bernd
