Java MSN Messenger library / Discussion / Open Discussion: Using JML with SOCKS proxy

Praveen Mittal - 2010-06-17

Hi,

We are using SOCKS version 4 proxy in our environment to connect to MSN. I tried using jml api to connect to MSN but it is not working. Whereas in the environment which is without proxy, the connection is working fine. Could you please help me in resolving this issue?

Thanks in advance.

Hi,

have you tried using java network properties like socksProxyHost and socksProxyPort?

Thanks a lot for the quick response.

I have not yet tried that. I was going through the API and couldn't find anything to set the proxy. Are you referring to the properties mentioned below: -

System.getProperties().put( "socksProxyPort", "1080");
System.getProperties().put( "socksProxyHost" ,"proxy.host.address");

If yes, then where should I set these properties. Should I set these before calling the login() API?

Yes before connecting to msn. These properties are considered from java when creating Sockets.

After setting these properties, my application is using the proxy and able to connect as well. But when I am trying to connect to a proxy which is SSL enabled, I am getting the SSLHandShakeException. Please let me know if anybody has faced this kind of issue.

thanks is advance.

You can try installing your own TrustManager which checks or trusts all Certificates.
