Change URL Path - Jitsi Spark Plugin

Hi guys,

I need change the URL when I click in the Jitsi VideoBridge Plugin in the Spark.

Today it opens the default Url: https://Domain_name:7443/jitsi/apps/ofmeet/?r=Roomid, I need change to https://Another_domain_name:7443/jitsi/apps/jitmeet/?=Roomid.

I decompress the jar file and I change the files: JitsiVideobridgePlugin.java, ChatRoomDecorator.java and BareBonesBrowserLaunch.java, and I make the jar File again, but the changes don't apply.

I know that plugin was upload, because I always change the version in the plugin.xml and when I verify the plugin, the version is changed.

What is my error? I am not Java programmer.
