任何服务器，如jboss或tomcat，我想从已部署的应用程序实例化一个类

Question

Is there a way that I can instantiate a Class in a deployed application by another deployed application if I know the package name and class I wan to instantiate? In any jboss or tomcat?

Thanks & regards, ~K.

Answer 1

Yes, you can achieve that by Reflection

Example

Bar aBar;
String barClassName = getBarImplClass();
aBar =
  (Bar) Class.forName(barClassName).newInstance();
