Within the IDE, you press "F1" and add the external Jar file to your project.
From then on, you can call and use classes defined in the Jar file.
You can even use the project dialog to get a list of classes and their respective methods.
A more detailed way would be to use tools like "Jad" for decompilation.
You might want to use the
Lassie project to get more information.
Sorry, but I'm a bit in a hurry and can't write a sample today.
Success!
