WELD-001408 Unsatisfied dependencies for type [EntityManager]

[bwallis42]

I'm trying to get a simple example (cut down from my real app) using JBPM 6.0.0.CR2 running in JBoss EAP 6.1. I cannot get it to deploy, possibly due to not being able to get a good idea about what dependencies I require. (I've attached the whole project source)

The error during deployment is as follows

12:00:19,617 ERROR [org.jboss.msc.service.fail] (MSC service thread 1-5) MSC000001: Failed to start service jboss.deployment.unit."simpleflow.war".WeldStartService: org.jboss.msc.service.StartException in service jboss.deployment.unit."simpleflow.war".WeldStartService: Failed to start service

I've guessed at what the dependencies should be (based on reading the poms from the examples and what classes I need). Ditto for the persistence.xml file (but if it is removed I still get the error so I don't think it is contributing to the error).

The jbpm dependencies used are as shown below. If I remove the dependency on the jbpm-runtime-manager then the error goes away. My actual code is mostly commented out and I don't think contributes to the error either. It is just trying to deploy a war that includes jbpm-runtime-manager that causes the problem.

in general you need to provide producers that gives the required components for the runtime. Take a look here to find some details on how to use jbpm6 with sample code.

Thanks for the pointer to the samples. I had to make a few pom changes to get them to work (excluding restlet and el-api dependencies and changing btm.version to 2.1.4 since I couldn't see a 3.0.0.SNAPSHOT version via my maven repository setup)

But now they build and run. I will study them now.

Would it be possible to upload your working example? I have the same problem and just can't get rid of it.

[bwallis42]

Attached. The zip contains two projects. One is a kjar containing the workflow and the other is a simple war project that deploys to JBoss EAP 6.1.

When simpleflow.war is deployed you go to http://localhost:8080/sf and should see a crude UI that lets you deploy the kjar (and its pom) from the kjar target directory. Once deployed you can create an instance of a workflow and complete it's human task after which it completes.

What I have is based on the examples at https://github.com/mswiderski/jbpm-examples.git

I've been building and running using jboss dev studio 7.0.1.GA, JBoss EAP 6.1, maven 3 and JDK 1.7.

Are you still getting the error about the EntityManager? if so you will need to take a look at the repository that you quote, because it contains an EnvironmentProvider class which is producing the instances of the EntityManager.

Thank you very much this helped a lot

[bwallis42]

Yes, still have the same issue with the entitymanager. I am providing my own Provider (which works ok).

I'm building against 6.0.0.CR2 via org.jbpm:jbpm-bom:6.0.0.CR2. The JBoss repositories that I am using (we run an artifactory server and these are included into a virtual repository)

1. http://maven.repository.redhat.com/techpreview/all
2. https://repository.jboss.org/nexus/content/groups/public-jboss/org/jbpm/jbpm-bom/
3. https://repository.jboss.org/nexus/content/groups/public/

jbpm 6.0.0.CR2 is found in the second of those repositories.

I don't see any class called EnvironmentProvider on my project classpath. Was it added after CR2? Should I be using CR5?

thanks
