Look at this blog post about how to get you started with jBPM
Hello,
A couple of weeks ago I started looking for human tasks tutorials in jBPM and I found that most of them used the business process that come with jBPM by default but I wanted something that would start from scratch and that could be followed step by step to achieve a working BPD with human tasks. Then I started talking with Salaboy about creating a tutorial about how to build a business process that involved human tasks.
The idea is to create a business process that will represent a loan request sent to a bank, where a user will request for a loan and depending on the amount requested
Let me try to guide you through this:
- Lets start by accessing the Business Authoring section from the Authoring menu on the top bar
- Then we’ll click on New -> Project, let’s call our project “BankingApp”
- After clicking on Ok…

Hi All,
I have the following problem with JBoss EAP 6.2 (configure in cluster mode) related to deployment of the my web application.
My web app is an war file that contains: processes defined with JBPM2 and REST services for start process, retrieve a tasks …etc..
I use JBPM 6.0.1.Final library to definiton and access at my processes and tasks.
The architecture is based on Spring that create an org.kie.api.runtime.manager.RuntimeManager object:
@PostConstruct
public void init() {
if (runtimeManager == null) {
RuntimeEnvironment environment = (RuntimeEnvironment) RuntimeEnvironmentBuilder.getDefault()
.entityManagerFactory(entityManagerFactory)
.userGroupCallback(userGroupCallback)
.addAsset(ResourceFactory.newClassPathResource(“test.bpmn2”), ResourceType.BPMN2)
.get();
((SimpleRegisterableItemsFactory)environment.getRegisterableItemsFactory()).addWorkItemHandler(“Log”, SystemOutWorkItemHandler.class);
runtimeManager = org.kie.api.runtime.manager.RuntimeManagerFactory.Factory.get().newSingletonRuntimeManager(environment);
}
}
but when deploy my web-app the line code with underline, I get the following error
ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/example]] (ServerService Thread Pool — 181) JBWEB000289: Servlet example threw load() exception: java.lang.ClassNotFoundException: org.drools.audit.WorkingMemoryLogger from [Module “deployment.example.war:main” from Service Module Loader]

But with JBoss EAP 6.2 configured in standalone mode, all works correctly.
Someone can help me kindly.

Hi there,
This is the error that you need to fix: java.lang.ClassNotFoundException: org.drools.audit.WorkingMemoryLogger
There seems to be a jar missing from your class path.

I have this jar in my pom.xml
org.drools
drools-compiler
6.0.1.Final
that contain WorkingMemoryLogger.java without any compilation problem
LikeLike
Sorry this dependency:
org.drools
drools-core
6.0.1.Final
compile
LikeLike
Ok, but if it is compile it will not be packaged inside your app and that’s why it’s not finding the class.
LikeLike
You mention that it fails only when it is configured in cluster.. that must be causing an issue and for some reason you end up with different class paths in different nodes.
I’m not an EAP expert, but something that I would like to understand better is why you are using spring inside a container, that can be causing issues.

I use spring to manage and trasfert KSession and ServiceTask genereted by RuntimeManager in other classes where the Rest service are defined. I olso tried to remove scope compile from pom.xml but does not work.
