public class JCClassLoader

extends java.lang.ClassLoader

Used to load classes that are not in the classpath, by loading them from a specific directory/jar file. The class will be loaded from the default classloaders first if possible, so do not use this mechanism to somehow override existing classes that are in the classpath. This is a wrapper around java.net.URLClassLoader and only provides convienince, sinplicity, safety, better exception processing, and better exception messages.
Example of use:

 
       ClassLoader loader = new JCClassLoader("i:/somepath/myjar-1.0.6.jar");
       Object main = loader.loadClass("com.mydomain.myproject.MyClass").newInstance();
       
       ClassLoader fileLoader = new JCClassLoader("i:/temp/");
       Object temp = fileLoader.loadClass("com.test.MyTestClass").newInstance()
