[jBPM Users] - Re: Extracting information from a jpdl file

by saraswati.santanu

Sebastian, I completely agree with you. The code I have given there is nothing more than a work around. There should be some method may be part of either Execution/OpenExecution interface and/or ExecutionService which does the job properly. And I have already voted for the issue. Ajay, If your requirement is to show all the tasks possible by an user even if the task is not currently active, then that will be fairly difficult to achieve. Data model of Jbpm4 does not support that. So you will have to change there. Since "Task" is the representation of manual tasks in Jbpm4, it makes sense to have actors/roles/swimlanes for tasks. Actors with something else does not make much sense.

[jBPM Users] - JBPM 4.2 Sub-Processs Not able to access Variables

by emailkuppai

Hi I have main Process < Main-Proc > invokes sub-process <Sub-Proc > on certain decision node. Main-Proc will be started by providing Process -Id Domain -Id and set of variables. i could able to access those variables in my main-proc (execution.getVaraibles() ) but i couldn;t get the same inside my sub-proc. even i couldn't say sup-proc execution.getParent().getVariable(). parent is comming as null. ??? any idea its a bug or i am i doing wrong.

[jBPM Users] - Re: Console: host not found error

by roger0681

Hi, all Thanks for your answer, Ronald. Though I've been searching for information on this fact for a few weeks, I had not reached an answer until now. I accept I'm not really used to JIRAs yet. After Ronalds response, I started browsing all JIRA issues (not only Console), and found this one in JBPM, issue 2562: "Hard-coded host and port for Tomcat". You can find https://jira.jboss.org/jira/browse/JBPM-2562 With what Tom comments in that JIRA, I found the JBPM server configuration file at: {JBOSS_HOME}\server\default\deploy\jbpm\jbpm-service.sar\jbpm-service-jboss-beans.xml In that file, I changed this code: <bean name="org.jbpm:service=ServerConfig" | class="org.jbpm.integration.jboss5.mgmt.ServerConfig"> | <property name="mbeanServer"><inject bean="JMXKernel" property="mbeanServer"/></property> | <property name="webServiceHost">${jboss.bind.address}</property> | </bean> | to this one (I'm changing webServiceHost property, and adding webServicePort): | <bean name="org.jbpm:service=ServerConfig" | class="org.jbpm.integration.jboss5.mgmt.ServerConfig"> | <property name="mbeanServer"><inject bean="JMXKernel" property="mbeanServer"/></property> | <property name="webServiceHost">publicIP</property> | <property name="webServicePort">publicPort</property> | </bean> | And now it is working correctly from outside the router/firewall. I didn't try it yet, but I suppose that now I will have the previous problem when trying to access this files from inside the network, if that network can't resolv the public IP.

[jBPM Users] - Re: What is the difference between a Task and an Execution?

by ajaygautam

Thanks again Santanu. Makes sense. Especially the "entry from db is removed" part. Now I understand why hibernate would complain about multiple entries being found, if I moved from one task to the next. (i.e. I should mark the first task as completed!)

[jBPM Users] - Re: Extracting information from a jpdl file

by ajaygautam

Thanks Santanu. getOutcomes does work, but the overhead of convert states to tasks is way too much... getOutgoingTransitions() always returns an empty list! - I think its broken - or maybe I am not using it correctly. Anyway... The requirement has changed: Now, we (me) need to supply the UI with the entire map at startup. As in: The UI starts up, and requests for the "action map" -> which is a list of who can perform which transitions. Unfortunately, I cannot find any easy way of storing role information with the diagram itself: the who can do what part. So, for now, I am thinking of adding an "allowedRoles" to each transition element. Will have to parse the jpdl file myself to get this information out of the file, but I will have all the data in one place. The unfortunate downside is that I won't be able to use the UI to edit the jpdl diagram... Is there an alternative way?

Thanks for clarifying this, Santanu. For the workaround you have supplied IMHO there should be a "clean" way to do it using the API. If you have not yet done it maybe you want to vote for the issue.

[jBPM Users] - Re: What is the difference between a Task and an Execution?

by saraswati.santanu

Task is a wait state where it requires manual action. Task typically represents runtime state of the manual task. So once the task is done the "Task" entry from db is removed. Execution is the common representation of runtime path of execution. So every process instance is an Execution, every sub process is also an Execution. There is execution underneath for tasks as well.

It is possible to get the outcomes if your current wait node is a task node. Since task node is the node for manual tasks, it might somewhat serve your purpose. This is the code for getting outcome for a task node: | taskService.getOutcomes(task.getId()) | If the wait node is some other wait node like "state" node, then there is no standard way to get the outcome. However you can still manage to get them, but the code may not look as clean. | //executionImpl can be obtained in multiple ways | //typically it can be obtained by type casting current process instance | //ExecutionImpl executionImpl = (ExecutionImpl)processInstance; | executionImpl.getActivity().getOutgoingTransitions(); | View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4269640#4269640 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4269640

[jBPM Users] - Examples do not work?

by jensaug

Hello, Should not all the provided examples be executable? When deploying the examples in jbpm 4.2, 20 out of 37 are excluded in the build.xml file. Simply including all of them again crashes the jbpm console (exceptions due to errors in process files). Also java src files are included in the business archive, java classes cannot be updated since ther're already in the jbpm/userlibs-folder etc. Including only the task/swimlane example is kind of confusing, no exceptions but process does not appear in console? I run the "demo.setup.jboss" environment (nice job btw!) Should a "Cleanup examples" JIRA be created perhaps? Cannot find any related to this currently. br, Jens View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4269629#4269629 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4269629
