HORB 1.3 beta 1 is the first beta test version of 1.3. Programs written for HORB 1.2 will work without recompilation in most cases. Also, HORB 1.3 has network level compatibility with HORB 1.2. However, I recommend recompilation. And HORB 1.3 may have bugs. Please use it after sufficient testing.
Programming in HORB was simplified as follows. Now, you don't need to instantiate horb.orb.HORB and you don't need to catch HORBExcepion and IOException.
class Client { public static void main(String[] argv) { Server_Proxy server = new Server_Proxy("horb://host.etl.go.jp:8444"); server.greeting("World"); server._release(); }
