Deplyoing Shell-ServiceTasks doesn't work

dcs1 — Tue, 06 Aug 2013 10:25:41 GMT

Hello everybody,i am not very familiar with activiti so it may be a stupid question. I have installed Activiti 5.13 on a centOs-machine which has a TomCat6 and a mysql-database. I have change the configuration to work with the mysql-database. All other configuration-files have default values.My firs

Use "activiti:type" as attribute, since "type" is an activiti extension to BPMN and you've mapped the activiti-prefix to it's url (xmlns:activiti="http://activiti.org/bpmn").

Thanks for reply.
As said in the Activiti user Guide 5.13 on the Shell example i first tried <serviceTask id="shellEcho" activiti:type="shell" >
with the activiti-prefix. It didn't work so i tried to use the type without the prefix which also didn't work and copied the second code here.
I also tried the activiti-prefix again seconds ago but the failure still exists. Other ideas?

Edit: I can upload it via manage->deployments->upload new and then it appears in processes-deployed process definitions but when i click start process it says:
<code>Warning! Could not execute shell command</code>
Something with missing rights? I have really no idea.

This is what is in our unit tests:

<code>
<serviceTask id="shellEcho" activiti:type="shell">
   <extensionElements>
    <activiti:field name="command" stringValue="echo" />
    <activiti:field name="arg1" stringValue="EchoTest" />
    <activiti:field name="outputVariable" stringValue="resultVar" />
   </extensionElements>
</serviceTask>
</code>

Looks pretty much the same as you have.

Is there any stacktrace you can see beyond the 'could not execute shell command'?

Do you see the problem?

Re: Deplyoing Shell-ServiceTasks doesn't work

dcs1 — Mon, 12 Aug 2013 09:57:43 GMT

I have tried it under a Windows 2008 VM with another Tomcat installation and could reproduce the failure under Activiti 5.13 and 5.12

Re: Deplyoing Shell-ServiceTasks doesn't work

jbarrez — Wed, 14 Aug 2013 09:54:43 GMT

I ran your process in a unit test and it just works fine. So it must be related to something on Tomcat…

Can you try to run it as a unit test and see what you get? (or as a main program)

Re: Deplyoing Shell-ServiceTasks doesn't work

jbarrez — Wed, 14 Aug 2013 12:02:46 GMT

<code> Nonsense.</code>

wtf?

I took the process xml you posted above.Put it in a unit test. Executed it. And it runs fine.

Re: Deplyoing Shell-ServiceTasks doesn't work

frederikherema1 — Wed, 14 Aug 2013 12:16:30 GMT

@dcs, Joram took the time to take your process definition, deploy and test it. Please have some respect for the people that are trying to help you.

The only thing I see that can be different, is the way it's deployed (through modeler rather than trough a unit-test). Have you tried deploying the process using a unit-test? Because that just works, as Joram just confirmed…

Excuse me. You missunderstood my comment. I meant that i wrote nonsense in this post. I didn't see your last answer and made a post. After i saw your post my post was as said nonsense and explained myself, that i didn't see your post. My intention was so say, please delete my post.
Excuse me again i never wanted to be impolite.
I have a lot of respect for you both, who help so much people and take the time to find answers between your development.

I started my JAVA EE Eclipse Juno, installed Activiti and started a new project. I installed H2 and added an activiti-database with your create-scripts. Afterwards i added the bpmn-file you can see above and startet a UnitTest which was created over right-click->activit->generate unit test which runs in an error:

<code>

Hope this will help you.

Hi,

This error says that your system was not able to execute the shell command. Is there a more detailed error message in the stacktrace?

Best regards,

Re: Deplyoing Shell-ServiceTasks doesn't work

dcs1 — Thu, 22 Aug 2013 14:55:09 GMT

Hello trademak,
thank you for helping.
This is the only error i get. Is there any more detailed information at some "hidden" place? Or more a place i don't know?
It's a traceable and repeatable behaviour, so if i need to enable some logging-features i could do it.
Awaiting your answer.

Best Regards,
dcs

Re: Deplyoing Shell-ServiceTasks doesn't work

trademak — Fri, 23 Aug 2013 09:32:03 GMT

The stacktrace should also include the original error. Is the stacktrace not longer then what you included?

Best regards,

Re: Deplyoing Shell-ServiceTasks doesn't work

greglee — Fri, 17 Jul 2015 03:40:33 GMT

I also have exactly the same problem on two slightly different platforms. The problem being the error when deploying a shell task model ie
<code>Validation set: 'activiti-executable-process' | Problem: 'activiti-servicetask-missing-implementation'] : One of the attributes 'class', 'delegateExpression', 'type', 'operation', or 'expression' is mandatory on serviceTask.</code>

Activiti 5.15.1 on CentOS release 5.9 (Final) 32bit, Oracle java version "1.7.0_25" 32bit, Apache Tomcat/7.0.39
Activiti 5.16.4 on CentOS Linux release 7.1.1503 (Core) 64bit, Oracle Java 1.7.0_79-b15 amd64, Apache Tomcat/7.0.62

Can you suggest what I can do to assist debugging this.
Thanks in advance.

Re: Deplyoing Shell-ServiceTasks doesn't work

jbarrez — Thu, 23 Jul 2015 09:12:20 GMT

How does your BPMN XML look like? If I recall correcly, the 'type' should be 'shell' for a shell task.

Re: Deplyoing Shell-ServiceTasks doesn't work

Ok, now i see it: i missed originally that this was in Explorer, not the engine (which i checked and verified).
The shell task is currently not supported in the import/export (it's also not in the palette of the modeler).
One workaround could be to make your own ServiceTask java class, make it extend from the ShellTaskBehaviour.
Then instead of the activiti:type, you use the activiti:class="com.company.YourClass".

Ok, thanks for that.
I can confirm that deploying via the REST api works and that once deployed it can be started via explorer or REST.
It would be "nice" if explorer and designer could handle it but we have a workaround 🙂

Hi,

I search this class 'ShellTaskBehaviour' but dont get it.

Could you please let me know in which package this class belongs, actually I am working 5.0.18 version of Activiti.

My requirement is I have a shell script and what to execute it through Activiti.

I shall be thankful if you provide me the solution for this.

Thanks
Mohit
