JavaEE - EJB over SSL works only if client and server are at the same host

[Pasha Turok]

Please help me. I can't do nothing with it. I have gf 4.0.1 and swing client. I want to get EJB over SSL. I've set all certificates. However, I can get it work only when client and server are at the same host. What I see in tcpdump when they are at the same host:

........

That is it starts working from one port but at some places it changes to 127.0.0.1 and a new connection is established.

When client and server at different host I don't get any exception but the client hangs. On server in log I have:

[2014-06-09T13:09:07.367+0400] [glassfish 4.0] [INFO] [] [] [tid: _ThreadID=139 _ThreadName=Thread-8] [timeMillis: 1402304947367] [levelValue: 800] [[

p: thread-pool-1; w: 1, WRITE: TLSv1 Application Data, length = 608]]

And on client I get endlessly the following message (with different cipher suite):

.......
Ignoring unavailable cipher suite: TLS_ECDHE_ECDSA_WITH_3DES_EDE_CBC_SHA
Ignoring unavailable cipher suite: TLS_ECDH_RSA_WITH_RC4_128_SHA

Ignoring unavailable cipher suite: TLS_ECDH_RSA_WITH_AES_128_CBC_SHA
Ignoring unsupported cipher suite: TLS_RSA_WITH_AES_256_CBC_SHA256
.......

How can it be fixed?

EJB SSL communication is tricky. It took me a couple weeks and I was working with a GlassFish security developer on it. I have a HOW-TO blogger article on it. http://mjremijan.blogspot.com/2011/06/secure-ssl-ejb-communication-with.html. This was written before GlassFish 4 but hopefully it is still applicable.

Thank you for your time and post. I totally agree that is REALLY TRICKY! I've done it. The problem was in my settings of /etc/hosts The full topic is http://stackoverflow.com/questions/24117040/javaee-ejb-over-ssl-works-only-if-client-and-server-are-at-the-same-host

And this solved the issue having the client and server on different hosts?
