try Class.forName("User") but note that you should call it from same directory OR add to classpath your User.class also check http://docs.oracle.com/javase/1.4.2/docs/api/java/lang/Class.html#forName(java.lang.String) if you using packages then try to add Class.forName("com.example.User")

You need to use the fully qualified name of the class, which includes its package. This is then typically used to look in the classpath, with directories corresponding to package parts. In your case, if the classpath includes D:\classes and the class User is in the package directory, this would work: Class.forName("directory.User");

forName requires the package path. What package do you want User to belong to? Here is an excellent example I found after a little bit of googling: http://www.xyzws.com/Javafaq/what-does-classforname-method-do/17

Class.forName(className) expects class to be in classpath and you can give fully qualified class name there

Note : className
