[xmlblaster] Re: Help! can xmlblaster do this?

[Marcel Ruff <mr at marcelruff.info>]

Hi Wu,

1. If the client can get outside without a proxy just use the SOCKET 
protocol layer,
see the drawing at

 http://www.xmlblaster.org/FAQ.html#FIREWALL

and see the java command line examples:

http://www.xmlblaster.org/xmlBlaster/doc/requirements/protocol.socket.html#example

all asynchronous callbacks will be tunneled back in the outgoing socket 
connection.


2. If you only have email access to the outside world you can 
transparently use the
email protocol (also for asynchronous callbacks). see

 http://www.xmlblaster.org/xmlBlaster/doc/requirements/protocol.email.html


3. You can as well use our tiny applet library which can be configured 
to use
a http proxy and receive asynchronous callbacks as well:

http://www.xmlblaster.org/xmlBlaster/doc/requirements/client.java.applet.html

It shouldn't be too hard to use this library outside of applets in an 
ordinary
java client.

So you have many options to choose from :-)

Please subscribe to our mailing list to be able to post to it,

best regards
Marcel
