Hi all, I'm trying to run a test sending a message. I'm running just the same code as the one in this link: http://docs.pushwoosh.com/docs/createmessage#PushserviceAPI-JavaSample but, never connect to the server. The error got is java.lang.RuntimeException: Could not generate DH keypair in handshaking. Any clue about what's happening? I'm using java6 u29.

Java 6 does not support DH parameters longer than 1024 bits, as well as some latest strong ciphers, while Pushwoosh is using 2048/4096 bits DH keys. The solution is to either update your Java, or consider not using SSL.

Hi Benedict, Thanks, I got it yesterday. As a temporary solution I'll use it without SSL until java version is updated in my backend.
