RE: [xmlblaster] 0.848 connection error

Aha!  Now I'm starting to get your client config scheme.

"protocol" for both regualar and callback connections, or you can fine tune
it if you want to use different protocols for each by specifying which you
want to use for each connection type (hence, "dispatch/connection" and
"dispatch/callback").

But as you note, with SOCKET, you wouldn't split it up since it uses the
same connection for the callback so no need to use the "dispatch" group of
parameters (unless you folks change the functionality).

Thanks again for the clarification.

Hi,

start the server:

  java org.xmlBlaster.Main -plugin/socket/port 7900

start the client:

   java HelloWorld3 -protocol SOCKET -plugin/socket/port 7900

works fine (-protocol will be used as the default for 'connection' and 
for 'callback').

You probably configured:

  java HelloWorld3 -dispatch/connection/protocol SOCKET 
-plugin/socket/port 7900

which forces the client side connection to SOCKET, but still leaves the 
callback connection
with the default setting IOR (Corba).
Unfortunately mixing protocols with SOCKET is currently not possible 
since SOCKET resuses
the same TCP socket to tunnel the callback back to the client.

Mixing protocol for client side access and callback access is free 
possible with Corba, RMI
and XmlRpc. So a client can connect with RMI and receive callbacks with 
XmlRpc:

  java HelloWorld3 -dispatch/connection/protocol RMI 
-dispatch/callback/protocol XMLRPC

Solution:
-----------
 You need to configure your client like this:

   java HelloWorld3 -protocol SOCKET -plugin/socket/port 7900

or like this
 
  java HelloWorld3 -dispatch/connection/protocol SOCKET 
-dispatch/callback/protocol SOCKET -plugin/socket/port 7900

or most precise like this

  java HelloWorld3 -dispatch/connection/protocol SOCKET 
-dispatch/callback/protocol SOCKET 
-dispatch/connection/plugin/socket/port 7900
