4 # This script will attempt to enumerate RMI interfaces and their exposed
5 # methods using JRuby.
6 #
7 # The script takes one argument, which is the URL for a remote RMI registry.
8 # Example:
9 #
10 # rmiquery.rb //127.0.0.1:1099
11 #
12 # Method names and prototypes are only available if RMI application stubs are
13 # included. You can include them by dropping their JAR or class files into
14 # the same directory that you run this script from and they will be
15 # automatically loaded.
16 #
17 # For info on RMI:
