Hi everybody,

I'm working on Eclipse editor plugin based on SQLEditor plugin from the book 'Java Developer's Guide to Eclipse'. My plugin works well when I test it and run it using Run->Run As -> Eclipse Application. However when I make jar plugin and copy to my eclipse plugins folder it doesn't work.

I have no idea what I'm doing wrong. I'll be grateful for any response.
/I can send my project by e-mail if anybody would like to help me./

I get the following:

------------------------------------------------------------------------------------
Could not open the editor: The editor class could not be instantiated. This usually indicates a missing no-arg constructor or that the editor's class name was mistyped in plugin.xml.
