javassist.tools.web
public class Viewer extends ClassLoader
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 calls main()
in the main class.
To run, you should type:
% java javassist.tools.web.Viewer host port Main arg1, ...
This command calls Main.main()
with arg1,...
All classes including Main
are fetched from
a server http://host:port.
Only the class file for Viewer
must exist
on a local file system at the client side; even other
javassist.*
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 in Viewer
.
For example, you can write something like this:
Viewer v = (Viewer)this.getClass().getClassLoader(); String port = v.getPort();
