Constructor Detail

ClassFileServer

public ClassFileServer(int _port,
                       java.lang.String _classpath)
Constructs a ClassFileServer.
Parameters:
port - for listening HTTP requests
classpath - the classpath where the server locates classes
Method Detail

getBytes

public byte[] getBytes(java.lang.String path)
                throws java.io.IOException,
                       java.lang.ClassNotFoundException
Returns an array of bytes containing the bytecodes for the class represented by the argument path. The path is a dot separated class name with the ".class" extension removed.
Overrides:
getBytes in class ClassServer
Returns:
the bytecodes for the class
Throws:
java.lang.ClassNotFoundException - if the class corresponding to path could not be loaded.
java.io.IOException - if file access operation fails

main

public static void main(java.lang.String[] args)
Main method to create the class server that reads class files. This takes two command line arguments, the port on which the server accepts requests and the root of the classpath. To start up the server:

java ClassFileServer

The codebase of an RMI server using this webserver would simply contain a URL with the host and port of the web server (if the webserver's classpath is the same as the RMI server's classpath):

java -Djava.rmi.server.codebase=http://zaphod:2001/ RMIServer

You can create your own class server inside your RMI server application instead of running one separately. In your server main simply create a ClassFileServer:

new ClassFileServer(port, classpath);
