[JBoss Seam] - Re: Problem with JBPM nodes and transitions
by chawax
I have another problem with transitions. I have a task-node with 2 transitions "Accepter" and "Refuser". These transitions can be fired from two command buttons in a JSF. These transitions go to nodes with Seam actions binded to them. But when JBPM calls these actions, the processInstance I get with the @In annotation is null ... Why is this processInstance null ?
Here is my JSF :
<h:dataTable value="#{taskInstanceList}" var="task" rendered="#{not empty taskInstanceList}">
| <h:column>
| <f:facet name="header">
| <h:outputText value="Description"/>
| </f:facet>
| <h:outputText value="#{task.description}"/>
| </h:column>
| <h:column>
| <f:facet name="header">
| <h:outputText value="Effectuée le"/>
| </f:facet>
| <h:outputText value="#{task.taskMgmtInstance.processInstance.start}">
| <f:convertDateTime type="date"/>
| </h:outputText>
| </h:column>
| <h:column>
| <s:button value="Accepter" action="#{afficherMessageConsole.accepterDemande}" taskInstance="#{task}" />
| <s:button value="Refuser" action="#{afficherMessageConsole.refuserDemande}" taskInstance="#{task}" />
| </h:column>
| </h:dataTable>
Here is my Java class :
public class AfficherMessageConsole {
|
| @In
| private ProcessInstance processInstance;
|
| @StartTask
| @EndTask (transition="Accepter")
| public String accepterDemande() throws Exception {
| return "validationDemandes";
| }
|
| @StartTask
| @EndTask (transition="Refuser")
| public String refuserDemande() throws Exception {
| return "validationDemandes";
| }
|
| public void demandeAcceptee() throws Exception {
| log("Demande acceptee !");
| processInstance.getRootToken().signal();
| }
|
| public void demandeRefusee() throws Exception {
| log("Demande refusee !");
| processInstance.getRootToken().signal();
| }
| }
And finally a part of the JPDL :
<task-node name="Avis de la RH">
| <task name="Validation de la RH">
| <assignment actor-id="#{actor.id}" />
| </task>
| <transition name="Refuser" to="Refus"></transition>
| <transition name="Accepter" to="Acceptation"></transition>
| </task-node>
| <node name="Refus">
| <action expression="#{afficherMessageConsole.demandeRefusee}" />
| <transition name="" to="End"></transition>
| </node>
| <node name="Acceptation">
| <transition to="End" />
| <action expression="#{afficherMessageConsole.demandeAcceptee}" />
| </node>
| <end-state name="End"></end-state>
|
I looked for samples in the source code, but there are no examples with nodes (and it's a shame). I'm not sure I understood well how to integrate Seam and JBPM, so feel free to tell me if I do something wrong !
Thanks in advance ;)

[JBoss Seam] - NotLoggedInException and no redirect to login page again
by gena777
Hello,
i'm trying to use the built-in security handling. With the pages.xml it works fine. But, if i try to restrict some controller action, no redirect occurs and the application just throws an exception
| 17:34:57,328 ERROR [[default]] Servlet.service() for servlet default threw exception
| org.jboss.seam.security.NotLoggedInException
| at org.jboss.seam.security.Identity.checkRestriction(Identity.java:222)
| at de.rwo.login.Identity.checkRestriction(Identity.java:59)
| at org.jboss.seam.security.SecurityInterceptor.aroundInvoke(SecurityInterceptor.java:38)
| at org.jboss.seam.intercept.SeamInvocationContext.proceed(SeamInvocationContext.java:68)
| at org.jboss.seam.ejb.RemoveInterceptor.aroundInvoke(RemoveInterceptor.java:41)
| at org.jboss.seam.intercept.SeamInvocationContext.proceed(SeamInvocationContext.java:68)
| at org.jboss.seam.intercept.RootInterceptor.invoke(RootInterceptor.java:106)

| at org.javassist.tmp.java.lang.Object_$$_javassist_22.buyNow(Object_$$_javassist_22.java)
The de.rwo.login.Identity.checkRestriction extends the Identity and only wraps the original checkRestriction call. If i catch the NotLoggedInException in such a wrapper and redirect manually (by using Pages.instance()...) to the login page, it works, but expect the correct behavior also/especially in case of NotLoggedInException.
Some application data(configuration as in the docu):
This view should be visible to all, but the only action of the page requires successful login to be proceeded.
Firing action in view
| <h:commandButton action="#{buyNowController.buyNow}" styleClass="submit" value="Kaufen" >
| <s:conversationId/>
| </h:commandButton>
The action itself
@Restrict("#{identity.loggedIn}")
| public String buyNow() {...}
|
Sounds simple but doesn't work :-(
Thanks for any help,
Gena

As you can see, i set the minimal java memory size at 1024 and the max at 2048. Thinking it should be enough :)
But the point is, i keep getting Java heap size problems (as i said earlier) and i don't know where they are coming. I don't think my apps are resource-consuming: they work perfectly locally, i can let my JBoss turn all day long without any problems, inside or outside my IDE.
But once it came to production, i get problems.
So, i had a look at the JMX Console, and in the Mbean {Jboss.system, type=ServerInfo}, i get the following data:
FreeMemory java.lang.Long R 42816 MBean Attribute.
| TotalMemory java.lang.Long R 66650112 MBean Attribute.
| MaxMemory java.lang.Long R 66650112 MBean Attribute.
So apparently from this data i understand that the actual memory of my JBoss is only 64mb... but why???
Please help me
