Create Deployment Artifacts option not working Please Help

[afshad]

After following the eclipse setup instructions in the user guide I added my own process to src/main/test in the activiti-engine-examples

Then i deleted the activiti-engine-examples.bar and activiti-engine-examples.jar files from the project.

Then I tried using the MB3 option Create Deployment Artifacts to create a new bar and jar files but nothing happens when I do that.
No indicator/progress nothing and no bar or jar files are created.

There is nothing in my problems view and nothing in the error log. The xml seems to be fine.
Ive attached an image of my eclipse workspace.
Can anyone please help me figure out whats going on.
Thank you.

If you're running the process in the Activiti demo setup, you should make sure your classes are on Tomcat's classpath when starting Activiti - that is, the classes are not and should not be part of the .bar file. If you look in your deployment folder in the project, you can see there's also a .jar file that's created. If you have the class in the same project, it should be in that jar, so it's all ready-made for you. Otherwise, you will need to create a jar containing the class yourself. Then you can drop the jar in Tomcat's lib directory for a quick solution. Most approaches for a more "enterprisey" solution tend to suggest repackaging activiti-rest and including the jar using Maven. You can then run that war on any container, because it contains Activiti, the REST API and your process' classes.

Thanks so much. that worked. It does need to be in the lib of the activiti explorer webapp in Apache as mentioned in other posts in the forum. By mistake I had two versions of apache installed and i kept putting it in the wrong Apache all this time thats why it didnt work. Its working now.

In regards to the Enterprisey solution you mentioned, we wish to use the activiti engine within our application which has the actual process classes and where we would create the delegates. We dont use J2EE only J2SE. So when you say Activiti and REST API, exactly which JARs would I need to include in my application? Which ones are needed to generate BPMN on the fly and create a process definition and run the process?

Good to hear you got it working.

What I meant is that you run your processes by repackaging the activiti-rest project from Activiti, as a whole. To that, you then add your own jar files for the dependencies on service task delegates.

The parts you at least need are in activiti engine, but that's included already by activiti-rest.

Hi All,

I am trying to upload a bar file but it throws the below error when i used a service Task. Could you help me with this?  I have tried all the above and still it does not work.

Error:    'resultVariableName' not supported for service tasks using 'class' | document_processing.bpmn.xml line 10 column 164

here is the bpmn file(Attaching the same):

Thanks,

You can only use a "resultVariable" to store the result of a SCRIPT-task. If you want to store some kind of result from a service-task, you should just set any variable you'd like on the DelegateExecution you get passed in the execute() method.

Create a zip-file with all needed processes/filed and rename to *.bar
