[JBoss jBPM] - Re: Fork that have conditions.. how??

by salaboy21

I was looking into the code and I find this that can help you: | // by default, the fork spawns a token for each leaving transition | if (script==null) { | transitionNames = getLeavingTransitionsMap().keySet(); | | } else { // a script is specified | // if a script is specified, use that script to calculate the set | // of leaving transitions to be used for forking tokens. | Map outputMap = null; | try { | outputMap = script.eval(token); | } catch (Exception e) { | this.raiseException(e, executionContext); | } | if (outputMap.size()==1) { | Object result = outputMap.values().iterator().next(); | if (result instanceof Collection) { | transitionNames = (Collection) result; | } | } | This means that you can add a script to tell the fork node with transitions you want to take.

[JBoss jBPM] - Re: Fork that have conditions.. how??

I don't think so, but let me review the code.. for what I have in my head the Fork code look for the leaving transitions to create sub tokens.. so.. i doesn't evaluate the conditions inside them... I hope it helps..

without writing new tags, what is the default behaviour of FORK , is it ignoring the conditions on its transitions ? can the regular FORK tag can be somehow used in order to process only the transitions that its condition is true ? , | <FORK name="fork"> | <transition to="x"> | <condition expression=#{true=true}/> | </transition> | <transition to="y"> | <condition expression=#{true=false}/> | </transition> | </FORK> View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4186666#4186666 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4186666

[EJB 3.0] - Re: How does JBoss handle Local and Remote interfaces

by rafaelcba

Hi All! Is possible force Call-By-Value on local invocations made cross EARs with isolated class loaders deployed on same JBoss? I have that scenario: Two EARs deployed on same JBoss AS: App1.ear - META-INF (descriptors) - lib/lib.jar (ClassA.class) - EJB.jar (MyBean1) App2.ear - META-INF (descriptors) - lib/lib.jar (ClassA.class) - EJB.jar (MyBean2) MyBean 1 make a local invocation to MyBean2 passing a intance of ClassA.class. When MyBean2 handle this invocation it throw a ClassCastException... Because ClassA passed by MyBean1 has other ClassLoader... I read at JBossWiki [1] that is possible force CallByValue on JBoss invocatios: |  | <mbean code="org.jboss.deployment.EARDeployer" name="jboss.j2ee:service=EARDeployer"> |  | <attribute name="Isolated">true</attribute> |  | <attribute name="CallByValue">true</attribute> | </mbean> | But don't work for local invocations. When this conf (true) make cense on JBoss???

[JBoss Cache: Core Edition] - Connection Closed error during

by m_antonyrajesh

For our application we need to get a unique ID from the request and store it in the DB and replicate in JBoss cache.So that next time when the same ID comes in the request we can load the node from DB and check for the existence of the ID.But sometime it is not working and throwing the below error in the console |2008Oct14|15:30:07.513|ERROR|ClientCertJsseListener1-193|org.jboss.cache.loader.JDBCCacheLoader|?(?:?)|Failed to load node for fqn /ID/00001: Closed Connection java.sql.SQLException: Closed Connection and as the result the same number(0001) is allowed twice and it does makes the major problem.Does anybody has idea on the same?

[JBoss jBPM] - Re: Fork that have conditions.. how??

by salaboy21

Ok, I wil try to write in my blog how to do that.. I think I will start with something like multichoicefork http://www.jboss.org/community/docs/DOC-11442 You can try to do an approach too and then we can compare it.

[JBoss jBPM] - Re: Fork that have conditions.. how??

by aben

Hi, thanks for the reply I need just the behaviour. my requirement is a fork with several transitions , on some of them / all of them will be conditions . the jbpm will take only the transitions that their condition evaluate to true for ex : <condition expression=#{true=true} <condition expression=#{true=false} only the first and the second transition shuold be processed.

[JBoss jBPM] - Re: deploy a procesee to jboss server suing java code

by ziccardi

If you need to deploy a process by code, you can use something like this: byte[] parBytes = readFully("yourfile.par"); JbpmContext ctx = JbpmConfiguration.getInstance().createJbpmContext(); new DeployProcessCommand(parBytes).execute(ctx); ctx.close(); If you want to deploy a simple xml process definition, you can replace parBytes with a String containing your XML. Hope this helps. Massimiliano.

[JBoss jBPM] - Re: Fork that have conditions.. how??

by salaboy21

If you need to that i think you can extend the Node class to make your custom Fork, because this involves the number of child tokens that you need to create. So, my question is, do you need a tag to do that? or just the behevior..?? Let me know what approach need your requierments and we can do it together..
