Question about External Jars

Recently, I have tried to extend a class and override it's method via Jar (don't have the java files, obfucated). This was successful, although as soon as I made a new package inside my eclipse project, I could no longer extend classes from that library, it only works with the default package. Also it doesn't give me an option to import this class from the jar library that I already imported into my project with eclipse.

One more thing, when I view the build path for the package, the Jar is in the library tab, but I still cannot extend from any of the classes in it.

Anyone know what is wrong here?

Thanks

Is the external Jar file incorporated into Eclipse's build path for this project? That's the first thing I'd check, and this can be done by right-clicking on the package and checking the build path.

My work firewall prevents viewing of that image file. Please explain what's going on as best you can.

What does eclipse say when you mouse-over the red underline under Loader?
