There are many open source workflow project.
But I couldnt choose right one.
Which one is better.
according to the standarts, completeness and usability.
This is a very lacking piece in the open source industry, the best that I know of is jbpm, jbpm.org. However if you are considering a workflow you might want to look to commercial products.... my 2 cents.
You are right. I have examined a lot of workflow.
I think jbpm is the best .
Because it is
jbpm is very flexible,
uml based ,
considers EAI patterns,
and uses hibernate as a persistency layer,
It is also uses JSR 207 standards that jbpm project leader is the founder of this jsr.
therefore it is state of the art in bpm.
I am right?.
Note : I am talking according to the two week reportt...
