1. Re: Using jbpm-human-task-war.war instead of DemoTaskService.class
jemmerling Jan 30, 2012 2:22 PM (in response to junaidmohammed)Although I haven't tried it, I think the simple answer is that you would kill the Demo Task Server. This is the reason:
Looking at the code for the WAR, I can see that it launches an instance of MinaTaskServer. If you look at the code for MinaTaskServer, I believe you will see that it is hard-coded to listen at port 9123. To put this in perspective, I believe this can be considered an example of "by convention" behavior as I believe this port number can be overridden however it doesn't require you to specify it, it will just listen at port 9123 "by convention".
So this seems to all be good, however, I don't think the WAR is a good deployment solution because it creates its own thread which is not managed by the Servlet Container - this could make life unpleasant when wanting to stop and start if using the Admin Console, etc.
Hope this helps!

2. Re: Using jbpm-human-task-war.war instead of DemoTaskService.class
melc Jan 30, 2012 3:38 PM (in response to jemmerling)Hello,
Indeed starting a thread within an application server is not a very good idea in general, however it will not necessarily hurt i.e. in cases that you don't care if the thread are managed by the app server, or you don't want to use resources from the app server context etc.
At first glance i feel the same with human task war, the thread that starts when the server starts will exist as long as the server runs, even if you could try to start another thread while running, you wouldn't be able because the human task port would be occupied. Of course one could always elaborate a bit on the code and make it managed possibly by using servletcontextlistener, ejb, quartz, spring etc
Regarding the jbpm-human-task-war you may need to add a little code regarding the task callback functionality, to see how just check the code of DemoTaskService and put it in HumanTaskServiceServlet you'll also need the jbpm.usergroup.callback.properties.
I managed to make it run , since i was getting some javax.naming.NameNotFoundException: TransactionManager -- service etc in relation to the "Could not connect to task client", by changing the following line within persistence.xml
from
<property name="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.JBossTransactionManagerLookup" />
to
<property name="hibernate.transaction.manager_lookup_class" value="org.jbpm.integration.console.JBPMTransactionManager" />
you will also need to put in WEB-INF/lib the jbpm-tm.jar found in the folder of your jbpm5.2 jbpm-installer.

3. Re: Using jbpm-human-task-war.war instead of DemoTaskService.class
junaidmohammed Jan 31, 2012 1:32 PM (in response to jemmerling)JE,
Thanks for your reply.
Yeah I didn't even start the DemoTaskService, which normally happens with ant start.demo.
Instead I only did ant start.h2 and then ant start.jboss.
I had already deployed the WAR into the deployments folder of the JBoss AS7 instance.
Unfortunately, didn't work.
As soon as I turn on the DeomTaskService, with ant start.human.task, everything works fine with no errors.
So something more needs to be done beyond turning off the DemoTaskService.

4. Re: Using jbpm-human-task-war.war instead of DemoTaskService.class
junaidmohammed Jan 31, 2012 1:38 PM (in response to melc)Chris Melas,
Thanks for your reply.
I went away and implemented everything you advised:
1. Copy callback logic from DemoTaskService.java to HumanTaskServiceServlet.java (making appropriate changes to avoid bugs)
2. Include the jbpm.usergroup.callback.properties
3. Alter persistence.xml with the advised changes
4. Include jbpm-tm.jar in WEB-INF/lib
I then redeployed the WAR file, but unfortunately, the same exception occured: "Could not connect task client".
Leaving things as is and starting the DemoTaskService, makes everything work again.
So I don't know if I have misinterpreted your instructions or perhaps there are further configuration changes that need to be done.

melc Jan 31, 2012 3:57 PM (in response to junaidmohammed)Can you please post what you get on the log of jboss so that we look at the exact exceptions ?
Thanks

7. Re: Using jbpm-human-task-war.war instead of DemoTaskService.class
junaidmohammed Feb 2, 2012 7:47 AM (in response to junaidmohammed)My apologies, I think the WAR file was not structured properly - I added a top-level folder by mistake:
- jbpm-human-task-war.war
- jbpm-human-task-war
- META-INF
- WEB-INF
- jbpm-human-task-war
So I removed the top-level folder but, unfortunately, the WAR no longer deploys.
Here is the new folder structure:
- jbpm-human-task-war.war
- META-INF
- MANIFEST.MF
- WEB-INF
- web.xml
- classes
- META-INF
- persistence.xml
<property name="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.JBossTransactionManagerLookup" />
<property name="hibernate.transaction.manager_lookup_class" value="org.jbpm.integration.console.JBPMTransactionManager" />

When trying to deploy through the JBoss Administrator, the following error is presented:
Unknown error
Unexpected HTTP response: 500 Request { "address" => [("deployment" => "jbpm-human-task-war.war")], "operation" => "deploy" } Response Internal Server Error { "outcome" => "failed", "failure-description" => { "Failed services" => {"jboss.deployment.unit.\"jbpm-human-task-war.war\".INSTALL" => "org.jboss.msc.service.StartException in service jboss.deployment.unit.\"jbpm-human-task-war.war\".INSTALL: Failed to process phase INSTALL of deployment \"jbpm-human-task-war.war\""}, "Services with missing/unavailable dependencies" => [ "jboss.naming.context.java.module.jbpm-human-task-war.jbpm-human-task-war.ValidatorFactory missing [ jboss.naming.context.java.module.jbpm-human-task-war.jbpm-human-task-war ]", "jboss.naming.context.java.module.jbpm-human-task-war.jbpm-human-task-war.Validator missing [ jboss.naming.context.java.module.jbpm-human-task-war.jbpm-human-task-war ]" ] }, "rolled-back" => true }
Is there a missing JAR library which usually contains jboss.naming.context.java.module.jbpm-human-task-war.jbpm-human-task-war.ValidatorFactory and jboss.naming.context.java.module.jbpm-human-task-war.jbpm-human-task-war.Validator?
Or is it that the namespaces are not correct?
