Get a web-item to link to java code

[Lailoken42]

I feel like this is something obvious, but I can't seem to figure it out. What is the simplest way to get a button to start running code in a Java class? Another related question I have, is where does the relative path of a link element in a web item begin from?

The few open source examples I can find of buttons that do things, rather than link to an absolute URL somewhere, aren't really helping me. I have put a lot of independent research and digging around into this and I am now stumped.

My goal (For now. One step at a time) is to make a button that is exactly the same as the Approve button for a pull request.

Any help with this issue would be amazing!

Hi Corin,

Relative links are relative to the root of the product. E.g. if your Stash is at http://localhost/stash, then a URL like /some/path would be http://localhost/stash/some/path.

As far as getting from a web-item button to Java code, there is no "direct" way to do this. You're asking how to take a button clicks on the client, and have it execute some Java code on the server.

This requires either using JS to make an AJAX call to a REST endpoint when the user clicks the button and then alters the current page based on the result your REST endpoint returns, or pointing the button's link to a servlet that serves your custom content in a fresh page.

Cheers,

Adam

Atlassian has great developer docs that will walk through most examples, but probably in some separate places.

* general stash development (make your first plugin)

https://developer.atlassian.com/stash/docs/latest/how-tos/creating-a-stash-plugin.html

* available module types ( your plugin will use 1 or more of these )

https://developer.atlassian.com/stash/docs/latest/reference/plugin-module-types/plugin-modules.html

* matching the UI

I have already read through the first two links several times, and yet am still unsure of the answers to my two questions. While I am fully aware that this could be a deficiency on my part, it is not from lack of trying and I was hoping for a more specific answer.

The documentation for web-items doesn't really explain what can be linked to in the link field. Every example I find just links to an absolute URL like "http://www.google.com". The component module seems to be for connecting modules with each other, so I thought it might help me, but the documentation doesn't really explain how to do that, just that it enables such a connection. The section on Creating Plugin Module Instances seemed promising, but it just explains about how parameters to the class are injected, not how to control execution.

I feel like I must be missing some really basic understanding of something, and maybe I am in over my head, but I am not really willing to give up, so any help would be hugely appreciated.

Thanks in advance!
