Hi, I'm looking for examples on creating a simple process (start->service
task->end) that executes Java code in the JBPM Console, not Eclipse. The examples
I've seen don't show adding Java code to service tasks or they refer to executing
the BPMN2 process in Eclipse, instead of the JBPM Console. I'm using JBPM5.4. I'm
sure someone's done this many times over, I'm just trying to get some ideas.
Thanks!

I guess you have to:
- Create work item definition with some name, for example "MyTask".
- Add a jar file with your WorkItemHandler implementation.
- Create a session template attaching your custom work item handler to "My
task".
https://github.com/droolsjbpm/jbpm/blob/5.4.x/jbpm-gwt/jbpm-gwt-core/src/...
https://github.com/droolsjbpm/jbpm/blob/5.4.x/jbpm-gwt/jbpm-gwt-core/src/...
This will make that the Knowledge Session is able to execute the My Task node.
But I think, to write your own work item handlers, you should have to use eclipse or some
other IDE.

Well, that's where I'm confused. I created the work item definitions with the
Process Designer's built-in editor and the work items show up as tasks in the Process
Designer. The JBPM Console sees the BPMN2 process created in Process Designer, as its
supposed to.
If the BPMN2 process contains the work item definitions and the JBPM Console executes the
BPMN2 process, shouldn't the work items also be executed by the Console?

What does your own work item definition do? Could you please mention an example of what
you are trying to achieve?
For example, if you have a custom work item definition, "Ping Server". Then, you
will have to have some code that pings a server. You can have it inside the Console
classpath, using it as I explained in the previuos comment. Or maybe calling a
webservice?

What I really want to do, as a first step, is to insert Java code into a Service task and
run it in the JBPM Console. Using work item definitions is secondary.
For example, executing Java code in a Script task is easy. I simple put the code in the
script attribute, save the process and run the process containing the Script task in the
JBPM Console.
Service tasks are less obvious. Setting aside the issue of work items, how do you insert
Java code into a Service task in the way you can with a Script task? I'm just looking
first to get a simple process containing one service task to run in the JBPM Console.

Hi David,
As Demian mention, the only other way (and recommended way) to add your custom Java code
is via a WorkItemHandler implementation. For that you will need a Java class. Once you
have your java class you will need to create a Jar file (container of compiled java
classes) and add that jar file to the jbpm console class path in order to use it. This
means that the jbpm console needs to have access to your compiled class, in the same ways
as any other application.
This is a really common way of accepting extensions for any other java application, so it
should be simple for you to create that.

Ok, thanks, Mauricio and Demian. I'm seeing now how this all fits. Thanks!

Hi Mauricio, I've tried the update to the jbpm-gwt-console-server.war file with mixed
results. I've narrowed the problem down to jbpm-gwt-console-server.war not being
"accepted" by the application server (AS 7.1) once the customer .jar file has
been added. It may be that I opened and/or closed the .war file incorrectly or perhaps
the same with the .jar file. Some people have said they user 7zip, others "jar
....". Can you suggest the commands to be used to create the .jar file of custom
work items as well as the command/utilities to open and close the ...server.war file?
Thanks, much.
