programmingly, I suggest you take a look at the java utility package, like these two: import java.util.jar.JarEntry; import java.util.jar.JarFile; or you can check out the api from ANT: import org.apache.tools.ant.taskdefs.Jar; if you want to present a list of classes on html page, you have to think of implementing the functionality in a servlet. google and check out their usage. Good luck.

i used a jar explorer tool before. It's a GUI tool that shows all classes in a file explorer fashion
