Utility Library Class not found

I extracted some code common to all my plugins into an library project in Eclipse. Everything was broken after that, even with the library's .jar in the Manifest. Here is the exception thrown by CraftBukkit:

This is the manifest file:

Code:

Manifest-Version: 1.0
Class-Path: iConomy.jar GroupManager.jar Permissions.jar EssentialsGroupManager.jar Essentials.jar ../RcjrUtil.jar

RcjrUtil.jar is in the main CraftBukkit folder and is referenced correctly(?) in the Manifest. Anyone know what I'm doing wrong?

 

Does it work without the RcjrUtil.jar on the manifest? I think that the way I got multiple jars to work was putting one per line, but maybe I was just being silly.

 

Try without any thing on Class-path ... and put lib into server folder

 

It is in the main server folder already. But why remove it from the classpath?

 

When I was working on wrapper it didn't work if I had libs listed in MANIFEST. Try deleteing those lines.

 

Never mind. I decided to export the utility classes in the same jar as the main plugin. Solved the problem.
