How to set Class-Path in Java manifest.txt

My project structure is as below

TestProject
    |
    |---- src
    |      |
    |      |---- package
    |               |
    |               |---- main.java
    |
    |---- externaLibs
               |
               |---- lib.jar

The manifest.txt is as below:

    Manifest-Version: 1.0

    Created-By: 1.7.0_06 (Oracle Corporation)

    Main-Class: package.Main

    Class-Path: ../externaLibs/lib.jar ./externaLibs/lib.jar /externaLibs/lib.jar externaLibs/lib.jar lib.jar (However I've tried these class paths to the lib.jar, none of them works)

Exporting my project with Eclipse, then, when executing the command: java -jar main.jar, the exception about being unable to find the external lib.jar always occurs:

   Exception in thread "main" java.lang.NoClassDefFoundError: org/example/SomeClassInLib

The output jar structure is as below:

testproject.jar
    |
    |---- externaLibs
    |        |
    |        |---- lib.jar
    |
    |---- pasckage
    |        |
    |        |---- main.java / main.class / and so on...
    |
    |---- META-INF
             |
             |---- MANIFEST.MF

What is the problem with the manifest.txt ?

Thanks for help.

In eclipse when you export, there is an option to export as Runnable Jar File. You can use the library handling radio buttons in the wizard to choose how the dependencies are handled. With the first two options, the dependencies get added into your jar. The third option creats an output folder and places the dependency jars in an accessible location for your jar.
