[jBPM Users] - Re: Problem moving from 4.1 to 4.2 using Spring configuratio

by saraswati.santanu

Thanks for sharing the solution Suganda. You have rightly pointed out that its always good to allow Spring to manage transaction when you use Spring-Hibernate combination. In fact you will not have an option other than this if you are using JMS or any non-db transactional service. I, however, would disagree with you on the spring interceptor current= true option. This is normally OK to have not transaction in a thread to start with. Then somebody (for this case Spring) needs to start the transaction. Ans everybody else should use the existing transaction. If, say from web tier (from a servlet) first call goes to some Jbpm command service call then I would expect that to start the transaction and not to crib about not having a transaction. In such a case current=false makes more sense. But again, with spring you can use OncePerRequestFilter kind of thing to get your transaction started. Such a case you have the option to use current=true. I am sure everything remains same for JTA transaction, so there should be no more pain for you in this.

[jBPM Users] - Re: [jbpm 4.2] My first simple application doesn't work :(

by saraswati.santanu

Silver, the code you have written is wrong. It will not work that way. You need to create a Jpdl file first. You can use the Eclipse GPD for that. And then use the Jbpm API to create ProcessDefinition etc. There is no class called ProcessFactory in Jbpm4. Second point that you need to understand is that a ProcessDefinition can not be started, it is the ProecessInstance which should be started. Now assuming you have created a flow jpdl xml file, then your main class should look like this: | private static ProcessEngine processEngine; | | private static RepositoryService repositoryService; | private static ExecutionService executionService; | | static { | processEngine = Configuration.getProcessEngine(); | | repositoryService = processEngine.get(RepositoryService.class); | executionService = processEngine.getExecutionService(); | } | | /** | * @param args | */ | public static void main(String[] args) { | //create new deployment object and ask it to deploy your flow | String deploymentId = repositoryService.createDeployment().addResourceFromClasspath("sampleprocess.jpdl.xml").deploy(); | | //now we query the process definition | ProcessDefinition processDefinition = repositoryService.createProcessDefinitionQuery().deploymentId(deploymentId).uniqueResult(); | | //start the process instance with the Id of the process definition | ProcessInstance processInstance = executionService.startProcessInstanceById(processDefinition.getId()); | } | View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4269124#4269124 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4269124

It can be saved by jBPM if it is serializable. Other options will be worked out in future releases of jBPM.

Hmmm even I learned something. I only knew Bonita (XPDL) as implemented on the PVM... Cool to know View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4269106#4269106 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4269106

Oh, and about 2: It's not an Artificial Neural Network, it's based on superposition and entanglement and touches on EPR But on a more serious note, it is an advanced statemachine for process graphs.

[jBPM Users] - Re: Support needed to install and use jBPM

by kukeltje

-Silver- Posts like this won't get you much help. Saying that the manual (that everybody uses) does not work for you without giving information about the errors is not enough. I'm also sorry you have been working on this for two weeks.

Try adding the mysql driver jar manually to the classpath. This is missing in 4.2 (and there is a jira issue for it) View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4269100#4269100 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4269100

Thank you Koen and others for taking time to respond to my post. That answers my question for now. Meghana View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4269089#4269089 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4269089

[jBPM Users] - Re: Roadmap of JBPM after 3.2

Hi Meghana, At this time there is no BPEL 2.0 effort planned within the jBPM project. As Sebastian points out, the BPEL 2.0 offering of JBoss will include the Riftsaw project, which is based on Apache ODE. As you correctly state, the OW Orchestra project builds on top of the PVM, albeit an older version, which started out as a collaboration between jBPM, Bonita and Orchestra. How you should handle upgrading to a BPEL 2.0 offering (whether Riftsaw or Orchestra) really depends on the particular requirements that you have. Normally it shouldn't be a problem running the jBPM 3 with BPEL 1.1 along either one of the above solutions.

Hello, I think that is not entirely true. Here is a link from Orchestra - http://orchestra.ow2.org/xwiki/bin/view/Main/FAQPVM As a JBPM-BPEL extension user, the message is certainly not clear, it is really confusing. If Bull and JBoss have in fact decided to work together why is it not stated on JBPM site? If PVM is very powerful and next generation engine, why did JBoss decide to spin off new BPEL project on Apache ODE? If this is not the right forum to ask these questions, please let us know who do we contact at JBoss? We have been trying through official channels as we are also interested in JBoss support but haven't heard back anything so far.
