Hi, How do I get the context if I am working with a web app deployed to tomcat? In Jboss it works out to: ProcessEngine processEngine = (ProcessEngine) ctx.lookup("java:/ProcessEngine"); What needs to be done to make it work on tomcat? Is there a sample code? I am using JBpm 4.1 and tomcat 6.0.

[Beginner's Corner] - Exposing/serving files via JBoss

by mikes3959

How do I expose/serve files using JBoss? In other words, the user should click on a network link like: http://www.mysite.com/file.kmz and read the file. Let me explain in detail, I'm generating a Google Earth file (kml/kmz) and others running Google Earth need to access it via the network link. The Google Earth client will constantly check the network link for this updated file. Can I write this file to a special JBoss directory that exposes it or do I need to create a war file that serves this file? And how do I do this? Can someone code me a sample?

[JNDI and Naming] - JNDI ObjectFactory - run-time registration

by olegpv

Hello, Is there a possibility to register some new custom JNDI resources (via custom ObjectFactory implementations) at run-time? I mean the following: 1) Here is an article about the standard approach for registering new JNDI resources for JBoss Web: http://www.jboss.org/file-access/default/members/jbossweb/freezone/docs/l... 2) It says that all custom javax.naming.spi.ObjectFactory implementations should be configured in server.xml 3) I need to register my custom ObjectFactory implementations at run-time, without any deploy-time modifications in server.xml Maybe there is a certain API for accessing JBoss Web configuration from Java code, which will allow such kind of registration?

[jBPM Users] - Re: Implementing Escalation in jBPM 4.1

I do not know what exactly is the problem with the BusinessCalendar but I created my process and my unit test within the examples project and the error has gone away. Now back to the actual goal. Please disregard my old post since there were some mistakes and things missing. My process definition looks like this: | <process key="escalation" name="escalation" xmlns="http://jbpm.org/4.0/jpdl"> | <start g="130,8,48,48" name="start1"> | <transition g="-93,-21" name="to timeout_task" to="timeout_task"/> | </start> | <task g="106,105,92,52" name="timeout_task" assignee="alex"> | <transition g="7,-32" name="to escalated" to="escalated"> | <timer duedate="5 seconds"/> | <timer duedate="5 seconds"/> | <timer duedate="5 seconds"/> | <timer duedate="5 seconds"/> | </transition> | <transition g="-50,-21" name="to task2" to="task2"/> | </task> | <task g="303,211,92,52" name="escalated" assignee="mike"> | <transition g="-50,-21" name="to task2" to="task2"/> | </task> | <task g="109,256,92,52" name="task2" assignee="peter"> | <transition g="-48,-21" name="to end1" to="end1"/> | </task> | <end g="132,367,48,48" name="end1"/> | </process> | My unit test follows: | package org.jbpm.examples.userescalation; | import java.util.List; | | import org.jbpm.api.Execution; | import org.jbpm.api.ProcessInstance; | import org.jbpm.api.job.Job; | import org.jbpm.api.task.Task; | import org.jbpm.test.JbpmTestCase; | | public class EscalationTest extends JbpmTestCase { | | String deploymentId; | | protected void setUp() throws Exception { | super.setUp(); | | deploymentId = repositoryService.createDeployment() | .addResourceFromClasspath("org/jbpm/examples/userescalation/escalation.jpdl.xml") | .deploy(); | } | | protected void tearDown() throws Exception { | repositoryService.deleteDeploymentCascade(deploymentId); | | super.tearDown(); | } | | public void testTaskEscalaton() { | | ProcessInstance processInstance = executionService.startProcessInstanceByKey("escalation"); | | List<Task> tasksAlex = taskService.findPersonalTasks("alex"); | | // check if Alex's task has been created | if(tasksAlex.size() == 0) { | fail(); | } | | // executing the job which would normally be executed by the JobExecutor | Job job = managementService.createJobQuery() | .timers() | .processInstanceId(processInstance.getId()) | .uniqueResult(); | | managementService.executeJob(job.getId()); | processInstance = executionService.findProcessInstanceById(processInstance.getId()); | | // we now should have arrived in the node "escalated" | assertTrue(processInstance.isActive("escalated")); | | // there should be an item in Mike's tasklist now | List<Task> tasksMike = taskService.findPersonalTasks("mike"); | if(tasksMike.size() == 0) { | fail(); | } else { | taskService.completeTask(tasksMike.get(0).getId()); | } | | // after Mike has completed his task we should have arrived in the node "task2" | processInstance = executionService.findProcessInstanceById(processInstance.getId()); | assertTrue(processInstance.isActive("task2")); | | // Alex's tasks still exists although it is obsolete now | tasksAlex = taskService.findPersonalTasks("alex"); | | // deleting is not possible since this task belongs to an execution | //taskService.deleteTask(tasksAlex.get(0).getId(), "obsolete"); | | // so we have to complete it, what is unwanted for BAM | taskService.completeTask(tasksAlex.get(0).getId()); | | // ########### but this fails with an exception ######## | | // there shouldn't be any tasks left for alex | //tasksAlex = taskService.findPersonalTasks("alex"); | //assertEquals(0, tasksAlex.size()); | | } | | } | The exception thrown when completeTask() is called: | ### EXCEPTION ########################################### | 16:19:12,140 INF | [DefaultCommandService] exception while executing command org.jbpm.pvm.internal.cmd.CompleteTaskCmd@ff45de | org.hibernate.ObjectNotFoundException: No row with the given identifier exists: [org.jbpm.pvm.internal.model.ExecutionImpl#2] | Am I doing anything wrong or does this mean you should not put timers on transitions coming from user tasks?

[JBoss Cache Users] - Design Question regd. using Jboss Cache in Web Application

by schamarthi

We have two spring based web applications and we are using JPA (Hibernate provider) with EhCache as secondarly level cache. We have some entities that are common between both the applications. now we want to have a cache at business layer and we thought of going with Jboss Cache and bind it to Jndi so that both each application is in sync with updates. | CacheFactory<String, Object> factory = new DefaultCacheFactory<String, Object>(); | cache = factory.createCache("jboss-cache.xml"); | cache.create(); | cache.start(); | | JndiTemplate jndiTemplate = getJndiTemplate(); | jndiTemplate.bind(JBOSS_CACHE_JNDI_NAME, cache); do you foresee any issues in this kind of setup ? Appreciate any kind of information in this regd View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4257210#4257210 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4257210

[EJB 3.0 Users] - Re: Session Bean with Multiple Interfaces and @LocalBinding

by jaikiran

The @LocalBinding annotation is for the default business interface proxy of the bean (which will implement all the local business interfaces). If you want to lookup interface specific proxy, we already bind those to the JNDI with the following syntax: BeanName/local-InterfaceFullyQualifiedName Example: UserServiceBean/local-xxx.yyy.UserAdminLocal UserServiceBean/local-xxx.yyy.UserServiceLocal | You will be able to see these JNDI names on the console.

[jBPM Users] - superstate timer error

by aapthorp

I have a process definition which includes a couple of timers; one on a state and another on a superstate. The timer on the state works as expected. However, when my process reaches the superstate it throws a StaleObjectStateException. Also, the timer seems to execute, but for each of the superstate's sub states as well as the superstate. Each time the timer repeats I see the same error. I've looked around the forum / Jira amd can't see that anyone else has observed this problem. My process definition is as follows: <state name="State 1"> | <timer duedate="20 seconds" repeat="20 seconds" name="late leaving"> | <script> | System.out.println("What are we waiting for ? "); | </script> | </timer> | <transition to="Moving" name="depart"></transition> | </state> | | <super-state name="Moving"> | <state name="Stopped"> | <transition to="Started" name="start"></transition> | </state> | <state name="Started"> | <transition to="Stopped" name="stop"></transition> | </state> | <timer duedate="30 seconds" repeat="30 seconds"> | <script> | System.out.println("We're late "); | </script> | </timer> | <transition to="end-state1" name="arrive"></transition> | </super-state> Produces the following: anonymous wrote : 10:56:40,515 INFO

[jBPM Users] - Re: Showing the process diagram in my own application

by sebastian.s

I feel a bit lost in the source code of the console but I had already managed to find the section for showing the diagram and there was a method call similiar to: | info = getActiveTaskNodeInfo(); | x = info.getX(); | y = info.getY(); | So the co-ordinates of the task nodes placed in the GPD seem to be deployed with the actual process definition, right? I can't find it anymore and it did not get clear to me where the information about the active task node was taken from.
