"Plugin or Class not found"- error while running ImageJ Plugin

[sharanbabuk]

Hello,

I'm working on developing a plugin for imageJ. When I execute code in eclipse, it doesn't show any error. But when I try to compile it in ImageJ by clicking on myplugin under "Plugins" tab, it shows error "Plugin or Class not found " followed by class name and then java.lang.ClassNotFoundExcception.

What could be possible error?
I dont see any problem in plugins.config. class name is proper in it.
Any help would be appreciated.
thanks
