The bug report that I linked to mentions a workaround using BouncyCastle’s JCE implementation. 2 for clients. CXF doesn't support NTLM authentication "out of the box" on Java 5, but with some additional libraries and configuration, the standard HttpURLConnection objects that we use can do the NTLM authentication. In order to start an SSL session, the first step is to establish a communication channel between the client and the server (a TCP connection in most cases) and then perform an "SSL Handshake" over the channel (Google "SSL Handshake", there are lots of good explanations).
For example, the customized EC curves cannot re-activate the disabled EC keys defined by the Java Security Properties. Establishing a Secure Connection Using SSL. 7u95 (Java 1. In order to implement SSL, java needs to be made aware of key, certificates and certificate chains, as described above.
