Reloading existing classes with existing data is likely to break things. You can load new code into new class loaders relatively easily: ClassLoader loader = URLClassLoader.newInstance( new URL[] { yourURL }, getClass().getClassLoader() ); Class<?> clazz = Class.forName(“mypackage.MyClass”, true, loader); Class<? extends Runnable> runClass = clazz.asSubclass(Runnable.class); // Avoid Class.newInstance, for it is evil.

The following code loads all classes from a JAR file. It does not need to know anything about the classes. The names of the classes are extracted from the JarEntry. JarFile jarFile = new JarFile(pathToJar); Enumeration<JarEntry> e = jarFile.entries(); URL[] urls = { new URL(“jar:file:” + pathToJar+”!/”) }; URLClassLoader cl = URLClassLoader.newInstance(urls); while (e.hasMoreElements()) { … Read more
You can use zipgrep on Linux or OSX: zipgrep “BEGIN REQUEST” file.jar If you wish to search a number of jars, do find libdir -name “*.jar” -exec zipgrep “BEGIN REQUEST” ‘{}’ \; where libdir is a directory containing all jars. The command will recursively search subdirectories too. For windows, you can download cygwin and install … Read more
