[jboss-user] [JBoss jBPM] - Re: Scheduler and asynchronous flow in in web app
1. I'll see if anyone in the Seam community has any ideas. (http://www.seamframework.org/Community/SchedulerIssueInWebAppWithMixedJBPMAndPageflow for anyone following this thread.) 2. I was thinking of creating a custom pageflow-action instead of end-task transition=Approve/ that would somehow replace the new jbpmContext with the original one and then programatically end the task. But after thinking this trough I don't think it's a good option. Thanks again for all your help.

[jboss-user] [JBoss jBPM] - Re: Scheduler and asynchronous flow in in web app
Thanks again Ronald!
After further debugging I found that the reminder-tag sends a reminder every 30
secs both with and without the additional JobExecutorLauncher. So the timer
works in some aspect. I guess Seam starts the scheduler without leaving
anything in the log.. sorry for not testing properly before posting.
The task causing the error is a nester Seam Pageflow and was started with
@In private Pageflow pageflow;
|
| @StartTask
| public String startTask() {
| pageflow.begin(TaskInstance.instance().getName());
| initializeProcessVariables();
| return SECUREPAGESDIR + TaskInstance.instance().getName() +
.jsp;
| }
and ended with
page name=showIncompleteTasksApprove view-id=/secure/taskList.jsp
| end-task transition=Approve/
| redirect/
| /page
which results in

[jboss-user] [JBoss jBPM] - Scheduler and asynchronous flow in in web app
Hi everyone, I'm trying to get asynchronous tasks and scheduling for things like reminder duedate=1 minute repeat=30 seconds/ to work. I'm deploying the application as a WAR using Seam and jbpm-jpdl-3.3.0.GA.jar. But I get complaints about the 'scheduler' service isn't started. And I don't think it is, since I have only declared jbpm-context | ... | service name=scheduler factory=org.jbpm.scheduler.db.DbSchedulerServiceFactory / | ... | /jbpm-configuration and not configured any org.jbpm.web.JbpmThreadsServlet in web.xml, since this wasn't included in the latest jbpm-3.3.0.GA release. (Instead it looks like it has been replaced with an EJB service, which isn't great for my WAR.) Could anyone kick me in the right direction here..? Is this Servlet removed and some other method should be used instead?

[jboss-user] [JBoss jBPM] - Re: Scheduler and asynchronous flow in in web app
Thank you Ronald (for this any _many_ other posts I've read on this forum)! I didn't find anything on this changes in Jira or anywhere else related to JbpmThreadsServlet.. Does anyone know 1. the location of documentation of how to configure it the new way? or 2. the name of the new filter? or 3. in which issue this change was made (so I could look up the made changes to the SVN and work backwards from there) Best Regards, Johan View the original post : http://www.jboss.com/index.html?module=bbop=viewtopicp=4194503#4194503 Reply to the post : http://www.jboss.com/index.html?module=bbop=postingmode=replyp=4194503 ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user
[jboss-user] [EJB 3.0] - Re: Is it possible to deploy EJB2 style entity beans in a EJ
So.. I've split the project into two jar files project-ejb.jar and project-ejb-entities.jar that are deployed within an .ear. The EJB version of project-ejb-entities.jar is 2.1. If the EJB version of project-ejb.jar is 2.1 too, everything works fine as before, but if I set the version of project-ejb.jar to 3.0 things start to go wrong.. using project-ejb-entities#bean-name in ejb-link elements I get the following 2007-08-29 15:07:48,261 WARN [org.jboss.ejb3.enc.DeploymentEjbResolver] can't find a deployment for path 'project-ejb-entities.jar' of ejb link 'project-ejb-entities.jar#TableProtectData' 2007-08-29 15:07:48,261 WARN [org.jboss.injection.EJBHandler] IGNORING DEPENDENCY: unable to find ejb-local-ref of interface org.ejbca.core.ejb.protect.TableProtectDataLocal and ejbLink of project-ejb-entities.jar#TableProtectData in ejb-jar.xml of TableProtectSession it might not be deployed yet and without specifying the jar 2007-08-29 15:07:48,261 WARN [org.jboss.injection.EJBHandler] IGNORING DEPENDENCY: unable to find ejb-local-ref of interface org.ejbca.core.ejb.protect.TableProtectDataLocal and ejbLink of TableProtectData in ejb-jar.xml of TableProtectSession it might not be deployed yet Using the same environment as before.

[jboss-user] [EJB 3.0] - Is it possible to deploy EJB2 style entity beans in a EJB 3.
Hi everybody, I'm about to try a phased migration from EJB2 to EJB3. When I changed version to ejb-jar version=3.0 xmlns=http://java.sun.com/xml/ns/j2ee; in ejb-jar.xml, JBoss lists every session bean as EJB3-service, but none of the old entity beans show up in the debug log. However I get a lot of 2007-08-28 09:00:30,558 WARN [org.jboss.injection.EJBHandler] IGNORING DEPENDENCY: unable to find ejb-local-ref of interface org.ejbca.core.ejb.ra.UserDataLocal and ejbLink of UserData in ejb-jar.xml of UserAdminSession it might not be deployed yet warnings for the entity beans. and later I get 2007-08-28 09:00:31,271 DEBUG [org.jboss.ejb3.stateless.StatelessDelegateWrapper] Starting failed jboss.j2ee:ear=ejbca.ear,jar=ejbca-ejb.jar,name=TableProtectSession,service=EJB3 java.lang.RuntimeException: Failed to populate ENC: env/ejb/TableProtectDataLocal global jndi name was null I also noticed some 2007-08-28 09:00:17,579 DEBUG [org.jboss.web.tomcat.service.TomcatDeployer] Unable to retrieve orbjavax.management.InstanceNotFoundException: jboss:service=CorbaORB is not registered. but I'm not sure this is related.. Isn't it possible to start the migration by simple running the old code in it's new environment? I'm using JBoss 4.2.1.GA and Sun's Java 1.5.0_12 on Ubuntu x64.
