Run and modify Openfire Meeting plugin outside Openfire

Hello,

I am new to openfire and have some questions regarding the execution and implementation of it.
I have downloaded the Openfire ofmeet plugin and want to change the code, I do not know how to execute the code (which program should I use) to know if my changes are correct.

The reason I want to change it is because I have made my own webrtc app but have found difficulties with the nodejs server I’ve implemented. Sessions tend to be unstable if the internet connecton is not good enough and would like to have a better control of the events. Thats why i want to use Openfire and try and adapt the plugin to my needs. Is it possible to do so?

Thank you for your help.
