JRuby DOM connection (start)

Start of JRuby DOM connection.txt

Hi--

Here's how (I believe) you can modify Web DOM within JRuby:

1) Modify jruby/src/org/jruby/JRubyApplet.java:
409a410,413
>             final IRubyObject wrappedApplet = JavaEmbedUtils.javaToRuby(runtime, applet);
>             runtime.defineGlobalConstant("JRUBY_APPLET", wrappedApplet);
>             wrappedApplet.getMetaClass().defineAnnotatedMethods(RubyMethods.class);
>

This will allow the console-based IRB session to have access to the
JRUBY_APPLET-- not just the non-console-based applet.

2) 
  jso = Java::NetscapeJavascript::JSObject.getWindow(JRUBY_APPLET)
  doc = jso.getMember 'document'
  loc = jso.getMember 'location'
  loc.getMember 'href' #=> "http://...."
