Intro to Spring Remoting with HTTP Invokers (#964)
* First test with log4j rolling appenders * small fix * Log4j rolling appender * First set up with rolling file on log4j 2 * Added logback code. * log4j2 more detailed example * log4j2 more detailed example * Improved names and examples * Fixed configurations * improved configs * formatted * Final fix * fixed formatting * Formatting fix * Fix sample apps to avoid try / catch * Fix request to replace files * Fix end lines * Log4j2 logger is shot down at the end. * Initial commit, the server starts launched from maven * made room for client and server projects * made room for client and server projects * base example works * poms restructured * packages restructured * packages restructured * Some renaming and a proper formatting string * Small renamings * Small renamings * Fixed invoked URL in client through fixing bean name
