[JBoss Seam] - Re: jBPM integration question

by fady.matar

I have other alternatives but would I still benefit from using the full features related to JBPM? One quick approach is to deploy a dummy process. But wouldn't it be appropriate to deploy the jBPM just when it's configuration is present?

[JBoss Seam] - Re: jBPM - What's in scope for a DecisionHandler?

by gavin.king＠jboss.com

If this decision is running synchronously with a JSF request, the contexts are shared with the request, so all those components will be just the same as normal.

[JBoss Seam] - jBPM - What's in scope for a DecisionHandler?

by bsmithjj

Hello, I have the following DecisionHandler node: | <decision name="IsTerminationRequest" expression="#{workItemManager.isTerminationRequest}"> | <transition to="Check Provisioning Type" name="isTerminationRequest"/> | <transition to="ABO Approve-Reject Request" name="aboApprove"/> | </decision> | Which Seam - jBPM components point to something meaningful when that expression is resolved and invoked? * org.jboss.seam.core.actor * org.jboss.seam.core.transition * org.jboss.seam.core.businessProcess * org.jboss.seam.core.taskInstance * org.jboss.seam.core.processInstance * org.jboss.seam.core.jbpmContext * org.jboss.seam.core.taskInstanceList * org.jboss.seam.core.pooledTaskInstanceList * org.jboss.seam.core.taskInstanceListForType * org.jboss.seam.core.pooledTask I know jbpmContext is points to something 'good'. What is the contract for all the rest of these components?

[JBoss jBPM] - setting and accessing process variables in jpdl

by shea.phillips

Hello, I am wondering how/if it is possible to set and access process variables from JPDL. I am most interested at the moment in being able to assign the return value from an action expression to a process variable for use elsewhere in my process definition. Here is a snippet from my process definition (not necessarily working) that invokes a Seam service/component and accepts a parameter and returns a String value or null, which I will test against in a transition element, and then use as a parameter in another action expression. Ultimately, the result of the latter service invocation will also be passed as a parameter to another service, although not shown here: | <process-definition xmlns="http://jbpm.org/jpdl-3.1.xsd" | name="interpretationProcess"> | | | <start-state name="start"> | <transition name="begin" to="determineInterpretationProcess"></transition> | </start-state> | | <node name="determineInterpretationProcess"> | <action expression="#{interpretationLookup.getIntepretationName($recordID)}"/> | <transition condition="#{empty interpretationName}" to="completed"/> | <transition condition="#{not empty interpretationName}" to="doInterpretation"/> | </node> | | <node name="doInterpretation"> | <action expression="#{interpretationService.doInterpretation($interpretationName)}"/> | </node> | | <end-state name="completed" /> | | </process-definition> | There are two issue I have here: 1. $myVar is a process instance variable created when my process instance is created - can it be referenced as shown above in an expression? 2. How would I assign the return value of my expression to a variable with some scope that is accessible within my process? My sense so far is that I may need to use the element... Note that I would like to avoid having a "stateful" service (in which I invoke a method that does not return a value, but has a separate method for retrieving the result of the method). I have seen this in at least one example, but I would prefer not to do this. thanks, Shea.

Wellthen, of course no process definitions will be created! What did you expect? You'll have to find some other means to deploy the processes, if you don't want to list them in components.xml.

[Clustering/JBoss] - Re: Farm Deployment with UDP not working

by bstansberry＠jboss.com

If your servers are having problems communicating, start with http://wiki.jboss.org/wiki/Wiki.jsp?page=TestingJBoss. If those all work OK, next step is to turn on TRACE level logging for category org.jboss.ha and see if it reveals anything. The suggestion to increase the buffer size was wrongheaded; based on faulty memory. The key thing is the buffers need to be bigger than the 512KB chunks that the FarmService breaks files into for transmission. The buffers in the original config were already large enough.

[JBoss Seam] - Re: jBPM integration question

by fady.matar

Yes gavin the configuration is there in components.xml now the thing is that i don't have any processes deployed the configuration looks as follows: | <core:jbpm> | <core:process-definitions></core:process-definitions> | <core:pageflow-definitions></core:pageflow-definitions> | </core:jbpm> | This is left intentionally blank, the purpose is to initialize jbpm only. I'm creating a workflow shell where multiple workflow instances are deployed. An effort with Tom Bayaens. Can you please assist in this?

[Persistence, JBoss/CMP, Hibernate, Database] - Re: Autoincrement DB2 JBOSS EJB CMP configuring

by risenhoover

Hi there, I don't know if I can answer your question exactly, but I can assure you that I've been using DB2 for about two years now, with hand-written JDBC code to do my inserts into tables with AUTO-INCREMENT, and I get DuplicateKeyExceptions all the frickin time. I've actually had to hand-write exception handlers to catch any exceptions during inserts, check the cause, and if it's because of a duplicate key exception, perform a manual increment and re-insert the row. I'm using DB2 v 8.
