I bought a third-party Java library which includes a JAR file and two DLL files. I wrote my own Java program which invoke the third-party JAR file. Now my question is how can I package all my code into a single JAR file which include all my code and the third-party JAR and DLLs?

I know SWT is such a case. The swt.jar includes dll files, but I don't know how to do this and how to make it work properly.

Use http://www.jdotsoft.com/JarClassLoader.php which could load DLLs and JARs from another JAR with unlimited nesting. For example, DLL could be in JAR which is in another root JAR. All DLLs and JARs are loaded like they are in a classpath or library path.
