java - How to export an Eclipse Project with External Jar dependencies?

Question

In Processing, I'd like to import a library I've written in Java which wraps around an external library (a .jar file).

Processing appears to import my own library, but when I call the constructor (which references some classes in the external library), I get a java.lang.NoClassDefFoundError in the Processing GUI console.

If instead of including the External .jar in my Eclipse buildpath, I use the library's actual source code and export all of that, Processing does not complain.

How might I be able to package up this project so that I don't have to include all of the library's source code (and instead just include the .jar file) in my Eclipse project?

Update: As per N.L.telaviv 's suggestion, I chose to export as a Runnable JAR. What worked for me was to select the option "Copy required libraries into a sub-folder next to the generated JAR." Here, another folder is created next to where your .jar is output containing the referenced .jar libraries.

Update2: The other option which works is "Extract required libraries into generated JAR." Doing so allows the JAR to access the references internally. It seemed as though the same would have worked with N.L.telaviv 's suggestion, but that does not appear to be the case. Choose this option if you don't want to have any extra files. You'll notice, if you explore the .JAR file, that the external library is in a separate package folder.

Use the Runnable JAR file export option.

Click on your project - export - java- runnable jar file - select the option to pack requires libraries in the jar
