Hi :-) I am not sure, I think one of the ways is: (I suppose the class-name
of that object is MyUtility)
* make MyUtility with SingleTon pattern
* make sure that MyUtility is loaded by:
- System classloader(for ex., put it in CLASSPATH)
- ext classloader(for ex., put it in JAVA_HOME/jre/lib/ext
* then, normally, when you want to use that object, you can use
the following code:
MyUtility myu=MyUtility.getInstance();
I think you can use the above code in:
- diferent Servlet in the same ServletContext
- diferent ServletContext
- diferent instance of Servlet container which run in the same JVM(?)
perhaps the above needs the following:
- that container doesn't disable CLASSPATH
- that container uses "Java2 delegate modol"
