[jboss-user] [JBoss jBPM] - Re: Token.signal() throws Exception from FieldInstantiator
Hello, SidKennedy is my project partner and I have the same problem with this exception in a slightly different context. @kukeltje To answer your Question, yes, the Tool declaration is somewhere else. I think the point is, that there is the XML action configuration that cannot be parsed in some kind of way. But I don't understand why. As I remember from the user guide, there is no xml schema or something like that that has to be validated when inserting the configuration inside of an action declaration in the jPDL. Here is my action declaration: task-node name=Big Step1 | task name=design modeling | event type=task-create | action class=org.sureal_projekt.spms.assignment.ResourceAssignmentHandler | resourceHooks | role group=PIM / | material group=PIM.design / | tool group=PIM.design / | /resourceHooks | /action | /event | /task | transition name=design modeling completed to=Big Step2/transition | /task-node And here is my Exception: 18:31:31,265 ERROR [FieldInstantiator] couldn't parse set field 'resourceHooks' to value 'resourceHooks xmlns=urn:jbpm.org:jpdl-3.2 | role group=PIM/material group=PIM.design/tool group=PIM.design//resourceHooks' | java.lang.NullPointerException | at org.jbpm.instantiation.FieldInstantiator.setPropertyValue(FieldInstantiator.java:70) | at org.jbpm.instantiation.FieldInstantiator.instantiate(FieldInstantiator.java:61) | at org.jbpm.instantiation.Delegation.instantiate(Delegation.java:163) | at org.jbpm.instantiation.Delegation.getInstance(Delegation.java:125) | at org.jbpm.instantiation.Delegation$$FastClassByCGLIB$$6bae1598.invoke(generated) | at net.sf.cglib.proxy.MethodProxy.invoke(MethodProxy.java:149) | at org.hibernate.proxy.CGLIBLazyInitializer.intercept(CGLIBLazyInitializer.java:161) | at org.jbpm.instantiation.Delegation$$EnhancerByCGLIB$$c441f5db.getInstance(generated) | at org.jbpm.graph.def.Action.execute(Action.java:122) | at org.jbpm.graph.def.GraphElement.executeAction(GraphElement.java:235) | at org.jbpm.graph.def.GraphElement.executeActions(GraphElement.java:212) | at org.jbpm.graph.def.GraphElement.fireAndPropagateEvent(GraphElement.java:182) | at org.jbpm.graph.def.GraphElement.fireEvent(GraphElement.java:166) | at org.jbpm.taskmgmt.exe.TaskInstance.create(TaskInstance.java:169) | at org.jbpm.taskmgmt.exe.TaskMgmtInstance.createTaskInstance(TaskMgmtInstance.java:144) | at org.jbpm.graph.node.TaskNode.execute(TaskNode.java:167) | at org.jbpm.graph.def.Node.enter(Node.java:316) | at org.jbpm.graph.def.Node$$FastClassByCGLIB$$d187eeda.invoke(generated) | at net.sf.cglib.proxy.MethodProxy.invoke(MethodProxy.java:149) | at org.hibernate.proxy.CGLIBLazyInitializer.intercept(CGLIBLazyInitializer.java:161) | at org.jbpm.graph.def.Node$$EnhancerByCGLIB$$af21a19d.enter(generated) | at org.jbpm.graph.def.Transition.take(Transition.java:119) | at org.jbpm.graph.def.Node.leave(Node.java:383) | at org.jbpm.graph.node.StartState.leave(StartState.java:70) | at org.jbpm.graph.def.Node$$FastClassByCGLIB$$d187eeda.invoke(generated) | at net.sf.cglib.proxy.MethodProxy.invoke(MethodProxy.java:149) | at org.hibernate.proxy.CGLIBLazyInitializer.intercept(CGLIBLazyInitializer.java:161) | at org.jbpm.graph.def.Node$$EnhancerByCGLIB$$af21a19d.leave(generated) | at org.jbpm.graph.exe.Token.signal(Token.java:174) | at org.jbpm.graph.exe.Token.signal(Token.java:145) | at org.jbpm.graph.exe.Token$$FastClassByCGLIB$$74df1c6e.invoke(generated) | at net.sf.cglib.proxy.MethodProxy.invoke(MethodProxy.java:149) | at org.hibernate.proxy.CGLIBLazyInitializer.intercept(CGLIBLazyInitializer.java:161) | at org.jbpm.graph.exe.Token$$EnhancerByCGLIB$$5bb04831.signal(generated) | at org.jbpm.graph.exe.ProcessInstance.signal(ProcessInstance.java:241) My Declaration of the invoked ResourceAssignmentHandler is very long, so I would like to avoid posting it here. :) But as I said, I think, that's not the point. And as SidKennedy wrote, the code that is invoked by the action does work very well. There is only THIS Exception, that crashes my web application. Do you have any idea what the problem might be?

[jboss-user] [JBoss jBPM] - Re: ant task for process archive deploying - Wiki?
Hello again, I have created an build.xml that runs correct. At least I got an *BUILD SUCCESSFUL*. The problem first was that the class org.jbpm.ant.DeployParTask doesn't exist in jbpm-3.1.2. It's now called DeployProcessTask. And the deploy parameter par now is called process. Thanks to the User Guide I wasted 3 hours to find this problem. After that the build still wasn't succesful. I got a *BUILD FAILED* because the jbpm tables were not found (i guess). So I put the following additional property to my hibernate.cfg.xml file. | property name=hibernate.hbm2ddl.autocreate-drop/property | Now the build runs. I get this *BUILD SUCCESSFUL* message. But the process definition is still not deployed!! I have checked the PUBLIC.JBPM_PROCESSDEFINITION table with the HSQL Database Manager but there is still only the websale process deployed. Does anybody has an idea what to do? I thought it must be easier to do this deployment. thanks lou View the original post : http://www.jboss.com/index.html?module=bbop=viewtopicp=4072437#4072437 Reply to the post : http://www.jboss.com/index.html?module=bbop=postingmode=replyp=4072437 ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user
[jboss-user] [JBoss jBPM] - ant task for process archive deploying - Wiki?
Hi at all, I have the following problem: I would like to deploy an process archive with an ant task. I have found the corresponding chapter in the jBPM jPDL 3.2 User Guide and tried to build my own build.xml. But I'm not so familiar with this ant stuff and I'm still getting the exception that the org.jbpm.ant.DeployParTask cannot be found. Is there someone out there who can just give me a small ant snippet to solve this problem? And wouldn't it be great to have such an ant task in the wiki for every people that have the same problem? Maybe the JbpmExampleApplications would be the right place. thanks in advance lou View the original post : http://www.jboss.com/index.html?module=bbop=viewtopicp=4071284#4071284 Reply to the post : http://www.jboss.com/index.html?module=bbop=postingmode=replyp=4071284 ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user
[jboss-user] [JBoss jBPM] - Re: java.lang.NoClassDefFoundError: javax/transaction/Synchr
It works!! I finally changed the tutorial code the following way. The problem was how the JbpmConfiguration was created. In the tutorial there was parsed an hard coded xml string to generate the configuration: | jbpmConfiguration = JbpmConfiguration.parseXmlString( | jbpm-configuration + | | jbpm-context + | service name='persistence' + | factory='org.jbpm.persistence.db.DbPersistenceServiceFactory' / + | /jbpm-context + | (...) | But when I changed this part to a simple invokation of the getInstance() methode everything worked fine. | jbpmConfiguration = JbpmConfiguration.getInstance(); | I wonder if the tutorial code is really buggy at this point. That would be pretty bad!! Or if I did something different so that the configuration initialisation went wrong. @dleerob thank again! :) bye, lou View the original post : http://www.jboss.com/index.html?module=bbop=viewtopicp=4070504#4070504 Reply to the post : http://www.jboss.com/index.html?module=bbop=postingmode=replyp=4070504 ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user
[jboss-user] [JBoss jBPM] - Re: java.lang.NoClassDefFoundError: javax/transaction/Synchr
Thanks for this first help. The NoClassDefFoundError is gone and the class seems to run some seconds longer. But another exception occurs - as usual. :-/ The exception: anonymous wrote : | Table not found in statement [select top ? processdef0_.ID_ as ID1_4_, processdef0_.NAME_ as NAME3_4_, processdef0_.DESCRIPTION_ as DESCRIPT4_4_, processdef0_.VERSION_ as VERSION5_4_, processdef0_.ISTERMINATIONIMPLICIT_ as ISTERMIN6_4_, processdef0_.STARTSTATE_ as STARTSTATE7_4_ from JBPM_PROCESSDEFINITION processdef0_ where processdef0_.NAME_=? order by processdef0_.VERSION_ desc] | | org.hibernate.exception.SQLGrammarException: could not execute query | at org.hibernate.exception.SQLStateConverter.convert(SQLStateConverter.java:67) | at org.hibernate.exception.JDBCExceptionHelper.convert(JDBCExceptionHelper.java:43) | at org.hibernate.loader.Loader.doList(Loader.java:2223) | (...) | Seems like there is a problem with the database, but I don't know where. I thought i read that the tables would be created automatically. Is that right? Can someone help me with this issue. BTW: I'm of course using the config files hibernate.cfg.xml and jbpm.cfg.xml from the /config folder of the jbpm-jpdl-3.2.1 download. I think that should be all right. thanks again lou View the original post : http://www.jboss.com/index.html?module=bbop=viewtopicp=4069592#4069592 Reply to the post : http://www.jboss.com/index.html?module=bbop=postingmode=replyp=4069592 ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user
[jboss-user] [JBoss jBPM] - Re: java.lang.NoClassDefFoundError: javax/transaction/Synchr
Hmm, right. The database tables are not created autmatically. At least not until you write an additional property to the hibernate.cfg.xml file. I have found a smal section about this in the User Guide. 7.6.2. The jBPM DB schema: http://docs.jboss.com/jbpm/v3/userguide/persistence.html#thejbpmdbschema; So far so good. I have added this property and ran the class again. The deployment seems to work. There is no exception at this point any longer. But now - I got another exception (Of course!) and I don't know what to do. It allways occurses when I try to close a JBPMContext in the following way: jbpmContext.close(); The exception: anonymous wrote : | problem closing service 'persistence' | org.jbpm.JbpmException: no jbpm tx service configured | at org.jbpm.persistence.db.DbPersistenceService.isRollbackOnly(DbPersistenceService.java:390) | at org.jbpm.persistence.db.DbPersistenceService.close(DbPersistenceService.java:212) | at org.jbpm.svc.Services.close(Services.java:222) | at org.jbpm.JbpmContext.close(JbpmContext.java:139) | Seems like there is something wrong with that 'tx service'. I have investigated a long time, but still have no idea what this tx service is about. I found a class called org.jbpm.tx.TxService but there is no real description about this class or even the hole package. Maybe there is someone out there who can tell me how to fix this problem and what this tx service is about. I really would like to know! :) thank! lou View the original post : http://www.jboss.com/index.html?module=bbop=viewtopicp=4069691#4069691 Reply to the post : http://www.jboss.com/index.html?module=bbop=postingmode=replyp=4069691 ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user
[jboss-user] [JBoss jBPM] - java.lang.NoClassDefFoundError: javax/transaction/Synchroniz
Hello,
I'm trying to run an example from the jBPM jPDL 3.2 User Guide. I have changed
the database example a little bit so that the jUnit assertions are just some
System.out.println and the program is starting by an public static void main.
Nice so far. But the main problem is to get all the necessary libraries to run
this simple class. I have added a lot of jars now, but there is still an
exception occurring.
The following exception occurs when i try to deploy the process definition with
the following code:
| JbpmContext jbpmContext = jbpmConfiguration.createJbpmContext();
| try {
| jbpmContext.deployProcessDefinition(processDefinition);
| } finally {
| jbpmContext.close();
| }
|
The exception:
| Exception in thread main java.lang.NoClassDefFoundError:
javax/transaction/Synchronization
| at org.hibernate.impl.SessionImpl.init(SessionImpl.java:213)
| at
org.hibernate.impl.SessionFactoryImpl.openSession(SessionFactoryImpl.java:473)

| at org.jbpm.JbpmContext.deployProcessDefinition(JbpmContext.java:173)
| at scr.own.ProcessWork.deploy(ProcessWork.java:91)
| at scr.own.ProcessWork.testProcess(ProcessWork.java:71)
| at scr.own.ProcessWork.main(ProcessWork.java:37)
|
It would be great if someone can tell me what to do!! Or is there somebody who
just can tell me what libs I need to run this tutorial example?
thanks in advance
lou
