This project holds some example multi-player games that uses the jetserver library. The server part is in src/main/java and the client part of the games are in src/test/java.

Pointers on main classes, classpaths and command line flags.

To start the game server
Set the classpath and provide the log4jconfiguration flag.
set serverclasspath = ./jetserver-0.1.jar;./....
java -cp $serverclasspath -Dlog4j.configuration=GameServerLog4j.properties org.menacheri.GameServer
To start the zombie client
set clientclasspath = ./jetserver-0.1.jar;./netty-3.2.4.Final.jar....
java -cp clientclasspath org.menacheri.ZombieClient

If you get the following property access exception
PropertyAccessException 2: org.springframework.beans.MethodInvocationException:
Property 'undead' threw exception; nested exception is java.lang.NoSuchMethodError: org.menacheri.aspect.AppManagedAspect.ajc$if$ac5(Lorg/menacheri/aspect/AppManaged;)Z
This is mostly because of the eclipse project not having proper binaries compiled to its target. Just goto Project->clean for both the jetserver as well as client project without doing a maven clean and it should work the second time.

If you get the following log4j configuration error, then it is mostly probably because you have not set the -Dlog4j.configuration=GameServerLog4j.properties as a flag in your vm path.
