Packaging JARs in Eclipse

I currently use the Eclipse SDK and I have a project that is using an external JAR to perform operations.

My question is how I can package that JAR so that it will work when I export this code to a JAR of its own.

In the end, I would like to have one file I can execute (a JAR) and have my application run... however right now it cannot because it can't run any of the classes in the JAR library I am using.

Can anyone tell me how to export a JAR in Eclipse, and keep this other JAR inside it?
