Good morning Giovanni.
1) In order to load a plugin without using an extension (very useful in
the develop fase) you should use the workbench-properties.xml. The
content of the file should be like this:
<workbench>
<plug-in>org.saig.myplugins.MyPlugIn</plug-in>
</workbench>
You must change also the program arguments at Eclipse by adding the
option -properties:
-plug-in-directory "D:\extensiones" -properties "workbench-properties.xml"
In your case, to use this for loading a tool, you should create an empty
plugin that only installs the tool at its initialize() method (as it's
done in the extension install method).
2) What do you mean with "level"? Do you mean "layer" instead? If it's
layer, currently there is no possibility to do this directly. You should
change/extend the RemoveSelectedLayersPlugIn class and change its
enablecheck to take into account this feature.
Regards,

Good morning,
thanks for the help that you have given to me. Now it works all correctly.
I have two questions:
- How I can load my button in the toolbar to the start without add it like
extension from the menù? I must modify the file workbench-properties.xml?
- Is possible load a level and not to allow the elimination of these to the
user?
Like always thanks for the help
Giovanni

Good morning again, Giovanni.
Look at the previous mail that I've send to you and change your code.
Anyway, the error that you're taking it's caused because with the
newInstance() method it's calling a parameterless constructor, and your
class doesn't have any.
Regards,

The error comes generated in the class PlugInManager in the method

plugIn.initialize( * new * PlugInContext( context , * null

}
The line that generates the error is that one evidenced
My class
* public * * class * DisegnaPoligonoPlugIn * extends * DrawPolygonTool
* implements * PlugIn
* public * * class * DisegnaPoligonoExtension * extends * Extension
Perhaps I would have to manage the button in an other way?
