I've decided to try using the http javascript method to communicate with the
server (like in the
systeminfo dhtml example). Basically, I will have a C# form which has a mshtml
webcontrol item
which contains the javascript logic to communicate with the server. Then when
messages are passed
from the server to the webcontrol, the control will notify the C# application.
By doing this, I can avoid writing an additional code on the server side as the
javascript
communicates with the existing servlets provided by xmlBlaster.
I've looked at the applet javadocs and I was wondering if it is possible to do
asyncronous
callbacks using different languages like C# and Java?
This should be possible,
"The servlet doesn't leave the doGet() method after an invocation of
actionType "connect"
keeping a permanent http connection."
so i believe any client opening a http request can receive further
updates with the kept alive
http socket connection, see on server side
xmlBlaster/src/java/org/xmlBlaster/protocol/http/appletproxy/PushHandler.java
On client side see
xmlBlaster/src/java/org/xmlBlaster/client/protocol/http/common/PersistentRequest.java
this is the code you need to re-implement in another language.

Marcel
Thanks.

Yes, I agree that the demo would work this way, but for security reasons, the
computer that is
hosting the xmlBlaster server is not exposed to the Internet. In fact, the only
computer
exposed
to the Internet is the webserver. The reason I like the java applet and java
servlet example is
that the java applet does not talk directly with the xmlBlaster server, but
through the
servlets.
Hi Chris,
what do you think about a proxy that will transmit the xml flow ?
Perhaps softwares like Apache or Squid can proxying xml-rpc ... I did
not try that.
I was wondering if the C# demo could be configured to talk to the servlets or
changed in some
way
to do this. I think this would be a great advantage to the xmlBlaster
development because then
the
servlets would be able to talk to clients that are written in different
languages. Although I
would like to help, my programming expertise in Java, C#, and C++ is limited
and just looking
at
the source for xmlBlasterAppletLib.jar makes my head hurt :-0
I'm looking forward to the c# applet! :-)
Sorry, but I won't do a demo like that. I don't know how to talk to the
servlet ... Perhaps in some weeks, if I can find some time, I will have
a look on it, but it is not really shure ... sorry ;o{
For da moment my focus is on :
- well understanding fine tune of QoS possibilities.
- C# and Flash with xml-rpc
- after I'll have a look at the SOCKET protocol to implement it with C#
- Then trying to make callback possible for Falsh applet. Perhaps a
new protocol plugin, if I could not plug Flash to the SOCKET protocol.
Some, enough job ;o)
Have a nice and happy christmas !!!
bye Chris,
Cyrille.
