public class Viewer extends java.lang.ClassLoader
A sample applet viewer.This is a sort of applet viewer that can run any program even if the main class is not a subclass of
Applet
. This viewwer first callsmain()
in the main class.To run, you should type:
% java javassist.tools.web.Viewer host port Main arg1, ...
This command calls
Main.main()
witharg1,...
All classes includingMain
are fetched from a server http://host:port. Only the class file forViewer
must exist on a local file system at the client side; even otherjavassist.*
classes are not needed at the client side.Viewer
uses only Java core API classes.Note: since a
Viewer
object is a class loader, a program loaded by this object can call a method inViewer
. For example, you can write something like this:Viewer v = (Viewer)this.getClass().getClassLoader(); String port = v.getPort();
