Hi. I decided to write here because I am stucked with a project on my studies. I need \
to write an agent (java application) which would be capable of retrieving business \
process definitions from jboss, connect to choosen instance of the process and \
intercept events like process started, process ended, process made a transition from \
one state to another, etc so that collected data could be sent to the console written \
by another team member and visualised there.
So I downloaded jbpm full installer and it installed everything for me, next I was \
able to find a lot of sample codes, but none of them worked. Those codes were ripped \
of it's context, so I don't have a knowledge on architecture and cofiguration of \
those technologies. From my research I found out that an agent in order to meet it's \
tasks can use for example:
1. drools api - that idea came from looking into jbpm-gwt-console code. I downloaded \
source code from jboss/jbpm site and there I found two classes: ProcessManagement and \
CommandDelegate which I assume are doing exactly the thing I need to. I assume that \
they get ProcessDefinition from jboss through KnowledgeBase, KnowledgeAgent, etc... \
but I don't know how, and I am unable to run this code. I am not sure if this is a \
right path to folow.
2. my second thought is to use JbpmContext and GraphSession class from Jbpm api but \
that way I got a lot of various exceptions etc... for example no query defined if I \
call findAllProcessDefinition etc... I am not even sure if I get the JbpmContext \
correctly. I don;t know from what place it gets it's configuration, dependecies, \
etc...
Please guide my toward correct direction. What is the best way to pull from jboss \
deployed process definitions and than ho to monitor it's instances? What api, \
technologies, libraries I need? How can I configure it?
