[jboss-user] [jBPM] - Integrating jBPM in Existing Web Application along with Guvnor / Designer
Ikram Babai [https://community.jboss.org/people/ikrambabai] created the discussion Integrating jBPM in Existing Web Application along with Guvnor / Designer To view the discussion, visit: https://community.jboss.org/message/828916#828916 -- Dear Commuity, I'm into the jBPM /Guvnor/Designer suite for about two months now - so still a newbie - However, I feel like I have convered a good (at least horizontal) space. I have got many questions on the overall best practices that one should use to use various components of the suite. *Background:* We are evaluating jBPM for executing processes that will dump data from some big data servers, do some manipulation and extract and dumpt the refined results into an RDBMS - The processes shoudl execute at cetain frequencies - lets say every 1 one - So we need a process triggering mechanism to invoke the BPMN2 process through jBPM runtime - we use quartz for that. The actual process will be designed by users using the Oryx designer that's embedded in Guvnor and then saved in the Guvnor's tables. We do not use the Human Task Service (not at least now) or any other rule base API that Guvnor exposes. Our Users will primarily be using Designer App to write the processes, compile and let the jBPM consume them. Following is the high-high level design on which my questions below are based. Tomcat Instance 1 |- | My Web App | | Usual Supsects | | (Hibernate/Spring) | | | | | | + | | jBPM Core | | (Engine/Runtime) | | (Work Item Handlers) | In Instance1 we build jBPM Knowledge Base by getting BPMN2 Processes designed and stored in instnce 2 below |___| Tomcat Intance2 |- | Guvnor + Designer | | | | | | | | | | | | Users Design | | BPMN2 Processes | | Save and Build | |__| *1. When to build the kBase in Instance1?* Knowledge Base is what jBPM Core knows and cares about - once built, the core engine can pick any process using its ID and get it executed - Process are designed in Instance2 above. Once desgined, committed and package is built, how do I tell jBPM core in Instnace1 to rebuild its knowledge base so that the latest defintion of the changed proces is avaiable to it on the next cron trigger? Is there a hook that Guvnor App provides that kicks in Instnace1 right away as soon as the package in instnace2 is built? The two easiest answers that I do not want to follow can be these. a. Build Knowledge Base in instance1 every few minutes. Get latest process defintion from Instance2 every 5 mintues, for instnace: I dont like this option (and Im sure most of you won't). What if something bad happens during such a high frequency operation and kBase is not built successfully? b. Currenly what Im doing is that everytime the user comes to the page (in Instance1) where process names are listed (from kBase), I re-create the kBase. Not a brilliant way of doing I agree - What if the users neverf comes to that page and just sings out after the kBase in Instnace2? So please let me know if there is a nice way that I can build my kBase in Instance1 on every Prcess/Package Build in Instnace2. *2. What Happens to an in-progress process when changes are done to an exisiting process, package built and kBase built in instance1?* Let say I know when and how to build my kBase - but then there can be some process which already started on the older version of the processes jBPM took from older kBase for execution? Will there exection be terminated or the runtime will execute the older version of the process and pick the new only in the next exection (not the current one)? *3. Versioning: Is there a way to tell jBPM to execute a particular version of a process?* *4. Partial BAM Reports? Possible?* The Business Activity Modeling tables (nothing complex 2/3 tables - one being PROCESSINSTANCELOG) are populated whenever the jBPM exection flows enters and exits a particular node. It works nicely except when one node's execution (say a Service Node) faces a problem. Just yesterday, I faced this problem. Let me explain. Suppose a process is in execution and when it reaches to node 5 for example - once of who's parameter is a big data query and that query had a syntax error. Obviously exceptions were thrown from that Service Node - But jBPM didn't save anything

My wid is like the - see the EnumDataType defined - the source code says the string passed into its constructor is a className - where do I put that class? I suspect it must point to a file Model Pojo jar that you can upload - but Can't there be an easy way - I really was fascinated to see the Enumeration in the Create New menu item - Is there a way to use Enumeration in this Wid and the Oryx will have it displaced as a combo?
