Here's a quick snippet of code from an Ant build script that demonstrates how to create a classpath variable in an Ant script, where the classpath is built from all of the jar files in your project's lib folder:

Summary: How to build an executable jar file that has dependencies on other jar files.

If you ever need to create an executable jar file that has dependencies on other jar files, this tutorial is for you. I'll show you ever thing you need to do -- including the use of an Ant build script -- so your users can just type something like this at the command line:

java -jar my-application.jar

to run your Java application.

Here's a Bourne Shell script I use to run a Java anti-spam program I wrote. The program I'm running isn't important, but what is worth sharing about this shell script is how I dynamically build the Java CLASSPATH by including all of the jar files in the lib directory.

Other parts of the shell script (showing a shell script for loop) may be worth sharing as well, but I think that building the Java classpath dynamically in the shell script is probably the most important part.

With that being said, here's the shell script:
