[Design of JBoss jBPM] - Re: Confused about infrastructure (SVN, Mailinglist, ...)

by kukeltje

Guys, I do not seem to be able to find an anonymous SVN repo. http://anonsvn.jboss.org/repos does not contain anything. Besides that I cannot login to the dev svn at all... CVS empty....

[Design of JBoss jBPM] - New extended WebService code

by salaboy21

I can't commit the new and improved code in modules/jpdl/ws/src/main/java/org/jbpm/command/ws, i have developed this code with more and improved methods to use the Web Services to interact with the Command Interface. If you don't want to modify the actual implementation i can commit it to a new ws2 package. I have rights to the Project PVM but i can't commit to modules/jpdl/ws/src/main/java/org/jbpm/command/ws.. can any one tell me how can I commit my code?

[Design of JBoss jBPM] - Re: Why is a ProcessInstance not the same as an Execution

by kukeltje

Joram is correct. In the demo system we have the way process are started is also done by a kind of PAO. Passing metadata to the engine is generic, but the way it should be used while instantiating a process differs a lot between systems.

[Design of JBoss jBPM] - Re: Why is a ProcessInstance not the same as an Execution

by jbarrez

This is true from the engine point of view, but for many of my projects the engine is not my entry point. If you can remember, this is something I showed in Dublin with the 'process access object - PAO'. Normally I have an interface which defines operations on the engine. All the clients that use this interface will set the same process variables. Off course, that's my (main) usage of jBPM, but I see many people do the same thing.

[Design of JBoss jBPM] - Re: Why is a ProcessInstance not the same as an Execution

by thomas.diesler＠jboss.com

The point is, that metadata that apply may Executions should be externalized a separate document. In J2EE you find this in the various deployment descriptors. The implementation i.e. the Servlet or EJB is seperated from that metadata. anonymous wrote : I put process variables on the instance Binds your implementation to the processing of this metadata. Every client of the API would have to invent its own meta data processing if this is not generalized at Engine level. Lets defer this discussion until I can show you a proposal in code. This is when http://jira.jboss.org/jira/browse/JBPM-1325 is done. You can then take that proposal and comment/improve on it.

[Design of JBoss jBPM] - Re: Why is a ProcessInstance not the same as an Execution

by jbarrez

Thomas, I don't agree fully with the example. The process definition is static. At runtime, instances are created from this definition (ie. class-object relation). If I need metadata, I put process variables on the instance before starting the process. Regional managers can then be picked based upon these variables. Changing this concept is bound to break some older implementations and is something that must be well-thought about before changing it...

Thanks for your feedback Alex. anonymous wrote : In PVM the process instance and the top level execution were recognized as being the same thing I started a separate thread for this here http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4162852#4162852 anonymous wrote : Is "attachment" a synonym of [process] variable Attachments associated with an ExecutionContext are indeed similar to process variables. Only that they use generics, which gives us compile time checking for process variable usage. Attachments in a more general term can be associated with other constructs as well. The ProcessInstance for example has Attachments as well. anonymous wrote : The transition router usage model is not clear to me It is generally important to separate the concerns of user Activity and the Transition to the next Node. A credit card activity deals with credit card operations and should not have to have intimate knowledge of the ProcessDefinition. For example if the Node that deals with credit card processing becomes a new Transition "goto checking account on failure" the Activity that deals with the credit card provider should not have to be touched. Generally, the execution of user code is one thing, taking the next transition is another - both are fundamentally different.

[Design of JBoss jBPM] - Why is a ProcessInstance not the same as an Execution

by thomas.diesler＠jboss.com

Relates to http://www.jboss.com/index.html?module=bb&op=viewtopic&t=138615 http://jbpm.dyndns.org/jbpmwiki/index.php?title=JBPM3PublicAPI The ProcessDefinition is the static definition of a process. An Execution is a specific execution of a process. There is however the notion of ProcessDefinition plus an associated set of meta data. For example an organization has a defined process for 'Order Processing' However, Order Processing is slightly different per region (i.e. different regional managers) It would be incorrect to force a duplication of the ProcessDefinition per region. Instead we introduce the notion of ProcessInstance that can be configured through additional metadata | pim.createProcessInstance(pd, "apac.properties"); | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4162852#4162852 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4162852
