Dear Everyone

Sorrry for my English because i’m Vietnamese.
I have a problem in deploy war file. I setup a Java Serlvet War:

Camunda BPM Process Application
A Process Application for Camunda BPM. [The project has been generated by the Maven archetype ‘camunda-archetype-servlet-war-7.9.2’]

My War file is delpoyed successfully with logs:

But after that I do not see “BPMLast” in the Cockpit (at Process Defination pages, http://localhost:8080/camunda/app/cockpit/default/#/processes )

Could you help me. Thanks in advances.

Can you upload your model so that i can take a look at it?

thangnch · March 22, 2022, 1:21pm

Sure Niall,

My model is quite simple because I just want to know if it can works.

process.bpmn (2.2 KB)

Niall · March 22, 2022, 1:27pm

So, your model looks good and the logs suggest you’re deployment was successful, so can you explain to me where you’re expecting the see the process and what is appearing instead?

thangnch · March 22, 2022, 1:33pm

Thanks Nail for your very quick response. I will try my best to explain:

I implemented a JavaDelegate in Java Maven Project follow your video: Tutorial: Camunda Enterprise Edition for Java Developers (Video 2) - YouTube
I use maven install to build a WAR file and deploy sucessfully.
I wish to see BPMLast in the Process Definition screen like your video (at 18:13, I can see Simple Demo in list). But BPMLast is not there.

Please help me! Thanks a lot.

Is there any particular reason you’ve picked this specific approach?
Generally, if you’re looking to just orchestrate Java Classes, it’s a lot easier to use camunda with spring boot. Id suggest maybe following this tutorial series.

thangnch · March 22, 2022, 1:41pm

Yeah. I almost watched all of your videos
I know that I can use camunda with springboot and I have finished a sample project with spring boot.
But in fact, I have a shared Camunda Engine which is used by some applications (the business dept required that).
That’s why I need above implementation approach.

Do you have any github link which I can clone and try to deploy again.

Niall · March 22, 2022, 1:48pm

Sadly, I’ve lost that exact code to time.
I’m very confused as to why you process is not appearing, it does seem like everything is correct.
Perhaps you can put your project on github and i’ll try to reproduce the error and fix it

thangnch · March 22, 2022, 1:51pm

Of course Niall, I put my code here: GitHub - thangnch/MiAI_Camunda_Sample: Demo of Camunda
It’s quite simple.
If you can deploy on your Camunda Engine, i will try to reinstall my Engine
Thanks a lot!

thangnch · March 22, 2022, 2:03pm

Sorry Niall, I finnally found the reason.

I install Camunda 7.16.0 ( on Tomcat) on both Ubuntu 18 and MacOS.
Everything is fine on Ubuntu, BPMLast is displayed and run normaly.
But on MacOS it does not work.
