Yes you're right, I you use the class name with the extension, Jigsaw
create a new instance and then call the init method. By default the name
registered is the classname without the extension. But, if you want to
modify it you can, launch JigAdmin and modify the ServletWrapper Identifier.

Regards, Benoit.
