Ok, here's what to do to get this test/demo working.

Jabber users
------------
You'll need two Jabber user IDs on your server:

client@localhost  - for use in jrpc-requester.pl
jrpc@localhost    - for use in jrpc-responder-client.pl

Component instance definitions
------------------------------
Add the contents of each of the .xml files to your jabber.xml
server configuration (make sure the names/ports don't clash 
with other existing names and ports. You will need to download
and install the http component if you haven't got it already.

The 'server' scripts
--------------------
There are a lot of scripts. Start each of the following in 
separate windows:

states-daemon.pl              the HTTP responder
httpgate.pl                   the HTTPgate gateway
jrpc-responder-client.pl      the Jabber-RPC responder client
jrpc-responder-component.pl   the Jabber-RPC responder component

[states-daemon.pl and states-client.pl are modified versions of two
of the scripts in the examples/ directory of the Frontier::RPC2 
library.]

The 'client' scripts
--------------------
Now we're ready to run the client scripts. There are two:

states-client.pl              the HTTP requester
jrpc-requester.pl             the Jabber-RPC requester

states-client.pl makes three calls:

- getStateName:    to the HTTP responder (states-daemon.pl)
- getStateList:    to the component-based Jabber-RPC responder
                   (jrpc-responder-component.pl)
- getStateStruct:  to the client-based Jabber-RPC responder
                   (jrpc-responder-client.pl)


jrpc-requester.pl also makes three calls:

- getStateName:    to the component-based Jabber-RPC responder
                   (jrpc-responder-component.pl)
- getStateList:    to the client-based Jabber-RPC responder
                   (jrpc-responder-client.pl)
- getStateStruct:  to the HTTP-based responder (states-daemon.pl)


There is debug output so you can see what's going on.

The two scripts states-client.pl and states-daemon.pl are
adapted versions of two of the example scripts that come
with Ken Macleod's Frontier::RPC2 module.
