Did you install the Derby core plugin ?

 This is from the documentation: "Note that both the Core and the UI plug-in need to be installed if any UI functionality is required, such as adding the Apache Derby nature, running the Derby network server, etc. is desired. "

I’m able to add derby nature in Eclipse Galileo but this error keeps coming in Eclipse Juno..

It works well on Helios.  

The latest Derby release doesn’t include the plugin, so you are probably using the plugin from version 10.8 (or older) wich was released last year, while Junio is from this year.  They are probably incompatible, and it seems that the plugin is no longer going to be maintained.

I don’t really know.  I guess you would need to read the release notes and/or similar documents that are always included with every new release.
