Question: testing the plug-in

[mgxcsd]

According to Plug-in developer's guide, created a jar file at the plugins folder right? And when run it with the command:
java -jar /path/to/SweetHome3D-4.5.jar(or by double-clicking on it), nothing happens [:(] ! What am I doing wrong???

Add some log or run it with the debugger as indicated in the Plug-in developer's guide to be sure it's taken into account at launch time.
If you want to be sure it's in the right place, add an existing plug-in and check yours and the existing one are in the same place.

I did everything but again nothing! Only the existing plug-in appears,and not mine!...Some time ago my plug-in worked, and when for some reason change the workspace,my plug-in stop to work. I tried to restore( [:))] ) the situation, but nothing! [:-/]
