[Beepcore-java-users] TLS and ECHO

[noe <nej...@in...>]

Hi Again,
    I still have the below problem ,anybody has the solution ?


---------------------------------------------------------------------------------------------------------------------
P.S=Thank you very much David. I really helped me!

Hello friends,

   When I run Beep example (Beepd,Bing) i can only use Echo Profile  
but  not the TLS one, it doesn't allow me to do that.Indeed, each time i 
try to use TLS, i get a message indicating that it is not supported by 
the host,but you know that it parses the xml doc and registers the 
profiles.

Lastly, i didn't change anything in the example files, except the 
"bing.java"  is ,now, asking for a TLS profile instead of an Echo.
Has anybody got the same problem or a solution?




Cheers

Actually, I get the below error. May be I forget to put some jar files 
to somewhere, any ideas?

[Beepcore-java-users] TLS and ECHO

   Is this a valid piece of code? Can I have a session secured with 
TLSProfile and then have a channel again with TLSProfile as in below?  
Or it is not meaningfull to do both?
If I only choose to secure the session but not a channel everything is 
ok but when i try to do both(for session and channel) it gives me 
errors, plus if i choose to establish a channel with TLS like  without a 
session TLS i again get errors!
 
  I am confused about this problem . 
 
  I am using java version "1.4.2_06"  and I have put the path for all 
the necessary jar files. Looks like not problem on installation and 
classpathing.
 
  Thanks for reading!



sample code is taken from BeepCore Java example:

               try {
                    session =
                        
TLSProfile.getDefaultInstance().startTLS((TCPSession) session);
                } catch (BEEPException e) {
                    System.err.println("bing: Error unable to start 
TLS.\n\t" +
                                       e.getMessage());
                    if (privacy == PRIVACY_REQUIRED)
                        return;
                }
            }
                                                                               
 
            // Start a channel for the echo profile
            Channel channel;
            try {
                //channel = session.startChannel(EchoProfile.ECHO_URI);
                channel = session.startChannel(TLSProfile.URI);        
//I added this line and it never works
            } catch (BEEPError e) {
                if (e.getCode() == 550) {
                    System.err.println("bing: Error host does not 
support " +
                                       "echo 
profile");                                     // or TLS profile
           }

This works out of the box for me.

Are you certain that you didn't change anything?

Can you use ethereal to see what beepd is advertising?
