How add Websockets integration to JIRA plugin?

[Paweł Murawski]

I wanted to integrate Websockets support to one of the JIRA plugins that we develop but to no success. I tried Atmosphere and Bristleback libraries and also native Tomcat Websockets support. The problems start after adding required dependencies to pom.xml - I run plugin using atlas-debug and it doesn't even start properly, there are many exceptions in the log (usually connected to OSGI).

The thing I'm trying to achieve is to create asynchronous communication between plugin and JIRA. If I use REST I would have to ask JIRA every few seconds if data changed and this is just wasting of resources. Can anone help me with this problem?

We finally used long polling in our project. Unfortunately I couldn't integrate websockets in any way. Even when you manage to do that still you have to consider what configuration your customer have - for example if you need to use specific version of Tomcat you are not guaranteed that your customer will also have it.

Nevertheless if you find any way to integrate websockets in JIRA plugin please share your knowledge here, as I am very interested if this is even possible.

Thanks for the response. I was able to deploy atmosphere-runtime via the UPM, as it's packaged as an OSGi repo. I was then able to get something working, although I didn't pursue the idea that far. Although I think it would work I believe there is other configuration people need to do if they front jira with apache or nginx, which is fairly common. This makes it a bit unsuitable for use in a "mass-market" plugin imho, atm. I may come back to it.

Thanks for your answer though.

Pavel, thank you for sharing your solution. I have a question about long polling approach - have you experienced any problems with reaching maximum number of simultaneous connections?

[Paweł Murawski]

We didn't have such a problem on our dev environment, also we've never heard from our clients that they had this problem on their JIRAs. Our plugin is dedicated for agile teams which usually don't have more that 10 people so big number of simultaneous connections shouldn't be a problem in our case. Have you experienced such a problem yourself?

@Jamie Echlin [Adaptavist] - wasted a day trying to get atmoshphere to play nice. Which approach did you use(servlet, filter, rest module, etc), do you have any examples or insight you are willing to share? I tried just defining a servlet module, but get class not defined errors for the core atmosphere servlet.

Jamie thanks for sharing this information. I am closing this question for now because of annoying automatic emails from Atlassian Answers.
