我已经学会了如何动态地将".class"文件加载到我的程序中,但是如果我在tomcat上运行它就不起作用了.这是代码:

package testPackage;

public class ModuleEngine {

    public static void main(String pth, String name) {

        ModuleLoader loader = new ModuleLoader(pth, ClassLoader.getSystemClassLoader());

        try {
            Class clazz = loader.loadClass(name);
            Protocol execute = (Protocol)clazz.newInstance(); 
            execute.run();
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        } catch (InstantiationException e) {
            e.printStackTrace();
        } catch (IllegalAccessException e) {
            e.printStackTrace();
        }
    }
}

public class ModuleLoader extends ClassLoader {

    private String pathtobin;

    public ModuleLoader(String pathtobin, ClassLoader parent) {
        super(parent);    
        this.pathtobin = pathtobin;    
    }

    @Override
    public Class findClass(String className) throws ClassNotFoundException …
