I have to develop a plugin for dotCMS. The problem is there is not a lot of information about plugin development in dotCMS' site.
In their site they say a good way to start is to look at the example plugin and start from there, but I find it complicated.
I was hoping that someone here would give me an idea of where to start, something like a brief tutorial about the plugins structure, languages, integration with dotCMS and that kind of stuff.
Here are a few pointers. I hope this helps:
dotCMS has a chapter on their documentation site about developing plugins for dotCMS 1.9. You can find it here: http://dotcms.com/docs/1.9/DevelopmentAndPlugins.
On the dotCMS plugins page there are a few plugins available that you can download and deploy: http://dotcms.com/plugins/index.dot.
