[1101]Make sure the same classloader loads your singletons
By Anonymous on 2004/11/05 17:46:15  Rate
// Because multiple classloaders are commonly used in many situations 
 // including servlet containers. you can wind up with multiple  
 // singleton instances no matter how carefully you've implemented  
 // your singleton classes. If you want to make sure the same  
 // classloader loads your singletons, you must specify the  
 // classloader yourself; for example:  
  
  
  
 private static Class getClass ( String classname )   
        throws ClassNotFoundException  {  
    ClassLoader classLoader = Thread.currentThread (  ) .getContextClassLoader (  ) ; 
  
  
    if ( classLoader == null )  
       classLoader = Singleton.class.getClassLoader (  ) ; 
  
  
       return  ( classLoader.loadClass ( classname )  ) ; 
     }  
  }  
  
  
 public class Singleton  {  
   // a singleton class 
  }
