[JBoss jBPM] - A question to the DecisionNode

by hamtho2

Hi, IÂ´ve got a question concerning the DecisionNode. As far as I can read from the documentation the first transition, that resolves to true within a DecisionNode will be used. Unfortunately I experienced a different behaviour for my test-process. This is part of what I have defined: | <start-state name="start"> | <transition to="isExceedingOrdered" /> | </start-state> | | <decision name="isExceedingOrdered"> | <event type="node-enter"> | <script><expression>System.out.println(executionContext.getNode().getName() + " entered");</expression></script> | </event> | <transition name="yes" to="isExceedingBuilt"> | <condition expression="#{contextInstance.variables.orderingState >= 160}" /> | </transition> | <transition name="no" to="ordered"> |  | </transition> | </decision> | | <state name="ordered"> | <transition to="isExceedingOrdered" name="state change"></transition> | </state> | | <decision name="isExceedingBuilt"> | <transition to="built" name="no"> | <condition expression="#{orderingState >= 182}"></condition> | </transition> | <transition to="fork" name="yes"></transition> | </decision> | | <state name="built"> | <transition to="isExceedingBuilt" name="state change"></transition> | </state> | In my first state a set the variable through a java test-class using | pi.getContextInstance().setVariable(orderingstate, 1); | So as I would say, in the first decision-node (named "isExceedingOrdered") after the starte-node, the first transition should result in false and then use the second transition (named "no"), because it does not have condition, therefor should result in true and then wait in the state "ordered". Unfortunately this works only if I put a condition in the second transition as well (as seen commented in my code above) otherwise it goes directly in the state-node "built". But this is only the case, when I define my transition "no" in "isExceedingBuilt" at first, no matter of what the result of the condition is. So this seems a bit strange to me, but possiblly I misunderstood something. So maybe someone can point me to the right direction.

[Installation, Configuration & DEPLOYMENT] - SOS: pb circular dependency between EJBs

by Nouredine13

I have asked the last time the problem of circular dependencies between EJB, there is someone who responded me and telling me to use the annotation @IgnoreDependency to one of the instance of Ejb injection. it solves the problem by half: I explain: when I use default injecting dependance with @EJB without specifying the name attribute, Jboss solve reference, in this case @ IgnoreDependency works well. By when I specifie the name of reference( @EJB(name="ejb/someEJB"...) that does not work. example: Hello1Bean classe : @EJBs( { @EJB(name="ejb/Hello2", beanInterface=Hello2.class, beanName="Hello2Bean") }) public @Stateless class Hello1Bean implements Hello1 { @IgnoreDependency @EJB(name="ejb/Hello2") private Hello2 hello; and Hello2Bean Classe : @EJBs( {@EJB(name="ejb/Hello1", beanInterface=Hello1.class,beanName="Hello1Bean") }) public @Stateless class Hello2LocalBean implements Hello2Local { @IgnoreDependency @EJB(name="ejb/Hello1") private Hello1 hello; with this case , i Have this probleme : --- MBeans waiting for other MBeans --- ObjectName: jboss.j2ee:jar=cyclic.jar,name=Hello2Bean,service=EJB3 State: NOTYETINSTALLED I Depend On: jboss.j2ee:jar=cyclic.jar,name=Hello1Bean,service=EJB3 Depends On Me: jboss.j2ee:jar=cyclic.jar,name=Hello1Bean,service=EJB3 ObjectName: jboss.j2ee:jar=cyclic.jar,name=Hello1Bean,service=EJB3 State: NOTYETINSTALLED I Depend On: jboss.j2ee:jar=cyclic.jar,name=Hello2Bean,service=EJB3 Depends On Me: jboss.j2ee:jar=cyclic.jar,name=Hello2Bean,service=EJB3 if someone has a solution, I currently work on the migration of a real application, and I have a major problem for progress. Thank's a lot.

[JBossWS] - Re: New to WS... Need help...

by alessio.soldano＠jboss.com

"PeterJ" wrote : As a hint - I never run the "default" configuration. Instead I make a copy of it and modify the copy and run that. This way I can easily "refresh" my configuration by deleting it and recopying "default" again. (I actually do this as part of my Ant script.) This is often useful, just remember that the JBossWS deploy procedure also changes libraries outside the JBOSS_HOME/server/your_configuration/ View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4156350#4156350 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4156350

[JBoss jBPM] - Re: replication of task at runtime

by WalterTaus

Hi, I have now implemented this ForEachForkHandler and it works. However, I have now come up with an extended scenario. In my ForEachForkHandler I create 4 tasks. However, in specific situations I want already to continue when the first two tasks are completed. Therefore, I have tried to implement a kind of housekeeping handler which I call from the join to get rid of the "unnecessary" tasks. My process consists of 1) fork 2) 4 activities which have been generated by the ForEachForkHandler 3) join When entering the join I call setNOutOfM with an appropriate value. Secondly I invoke the handler listed below: | ublic class MultiinstanceHouseKeepingHandler implements ActionHandler { | | @Override | public void execute(ExecutionContext ctx) throws Exception { | // TODO Auto-generated method stub | Token t = ctx.getToken(); | Collection til = ctx.getTaskMgmtInstance().getTaskInstances(); | Map childTokenList = t.getParent().getChildren(); | Set ks = childTokenList.keySet(); | Iterator it = ks.iterator(); | while (it.hasNext()) { | Token ct = (Token)childTokenList.get(it.next()); | if (ct == t) | continue; | Iterator itil = til.iterator(); | while (itil.hasNext()) { | TaskInstance ti = (TaskInstance)itil.next(); | if (ti.getToken() == ct) { | ti.cancel(); | ct.end(); | break; | } | } | } | } | } | The process continues correctly with the task following the join. However, I cannot get rid of the other unwanted tasks and they stay forever on my worklist. What am I doing wrong here?

[JBoss Portal] - Error with jackrabbit installing JBoss Portal

by wilson.braga

JBoss Portal 2.6.5 GA Portal downloaded from JBoss website JBoss AS 4.2.2 GA JDBC PostgreSQL Ubuntu 8.04 Problem: I tried instal JBoss Portal in an application server that already had other application running. The follow exception show up: "org.jboss.deployment.DeploymentException: Could not create ConnectionFactory for adapter: jboss.jca:service=TxCM,name=librarytoolRepository/local". And it does not happen when each application run alone. I think the problem is that both applications are using the same jackrabbit , when they need to use differents ones. It is my problem clear? Someone have some suggestion for me? Thanks for attention.

[Installation, Configuration & DEPLOYMENT] - Re: java.lang.OutOfMemoryError: Java heap space

by PeterJ

You can change the heap sizes in the run.bat or run.conf script (depending on you operating system). Look for the JAVA_OPTS setting, and change the value for the -Xmx option.

[JBossWS] - Re: Upgrading from jbossws-native-2.0.2.GA to jbossws-3.0.1-

by alessio.soldano＠jboss.com

This might be due to a bug that has been fixed in 3.0.1 that caused the chunked encoding to be always disabled http://jira.jboss.com/jira/browse/JBWS-2000. The default jaxws client configuration has chunk size = 2048; if the server you're calling doesn't support chunked encoding, you might want to disable it setting the http://org.jboss.ws/http#chunksize property to 0 (zero) in the standard-jaxws-client-config.xml (or in your own config). I also suggest you to try using http/1.0 when .NET endpoints are involved and this kind of issues appear.

by PeterJ

For JON you are pretty much limited to the documentation and help text that comes with it. I know of no book or outside resources that described its use.
