Configuring SSL Support

When using an "https" URL, CXF will, by default, use the certs and keystores that are part of the JDK. For many HTTPs applications, that is enough and no configuration is necessary. However, when using custom client certificates or self signed server certificates or similar, you may need to specifically configure in the keystores and trust managers and such to establish the SSL connection.

If you are getting strange errors (generally not soap faults, but other HTTP type errors) when trying to interact with a service, try turning off chunking to see if that helps.
