Custom Work Item Handler

[scarenci]

Hi everyone,

    I am very confusion about how to create a custom work item handler, I find so many diferent materials about how to create and none worked for me. I am very frusted with that I hope that you guys can help me!

My principal reference was this blog and this video:

Blog: FXApps: Creating custom Work Item Handler in BPM Suite/jBPM 6

Youtube: jBPM6.3 - Creating Service Task - YouTube

My steps was:

1) Get the code from github and export to jar in a eclipse:

GitHub - jesuino/hello-world-work-item-handler: The simples Work Item Handler as described here: http://fxapps.blogspot.…

public class HelloWorkItemHandler implements WorkItemHandler {


public void abortWorkItem(WorkItem wi, WorkItemManager wim) {
System.out.println("Oh no, my item aborted..");


}


public void executeWorkItem(WorkItem wi, WorkItemManager wim) {
System.out.println("Hello World!");
wim.completeWorkItem(wi.getId(), null);
}


}

I saw here that in this example don't have kmodule.xml, is this right? Or I have to configure the application and the kmodule.xml in the META-INF?

2) To import this jar in the application I was reading that was necessary to put the jar in:

jbpm-gwt-console-server.war/WEB-INF/lib or

C:\CivitasProcessos\jbpm\dependencies or

Configure this in the repository like: Tools -> Project Editor -> Project Settings -> select Dependencies. Add from repository and them configure the kbase and ksession

What is the correct configuration?

3) I had to configure the WorkDefinition and i saw two configuration for that

New Item -> Business Process -> WorkDefinitions

[

   "name" : "HelloWorkItemHandler",

    "displayName" : "Hello World!",

    "icon" : "defaultemailicon.gif"

]

OR

[

    "name" : "HelloWorld",

    "description" : "Prints hello World in the console",

    "displayName" : "Hello World!",

    "defaultHandler" : "mvel: new org.jugvale.jbpm.workitemhandler.HelloWorkItemHandler()",

    "mavenDependencies" : [

          "org.jugvale.jbpm.workitemhandler:hello-workitemhandler:1.0"

     ]

]

4) In the Build and Deploy I have this error:

Deployment of unit Imagem:CustomHandlerTask:1.0 failed: java.lang.RuntimeException: java.lang.IllegalStateException: Cannot find ksession, either it does not exist or there are multiple default ksession in kmodule.xml

If I remove the configuration from kbase and ksession I can deploy but the processes definition dont appear!

I appreciate any kind of help.
