The players + are connected via network using CORBA-based RMI/IIOP protocol and + make they moves with the help of the Swing-based + interface. While playing, the users can also chat. + </p> + <p>The system consists of the single server and any number of + interconnected players. The person, willing to play, starts the + client and connects the server. The server redirects call to the + partner that has previously connected the same server, also willing + to play. + </p> + <p>The game desk is a field where it is possible to set O's + and X'es, one per move. The goal is to get five O's in a row while + preventing your partner from getting five X's in a row. Vertical, + horizontal and diagonal rows are allowed. The system detects the + loss-victory situation on the desk, but currently does not serve as a + playing partner, requiring at least two human players for this game. + </p> + <p>Both players can at any time reset the game (restarting it with + the same player) or leave the game (disconnecting). The disconnected + player can contact the game manager again, requesting to find another + partner. + </p> + <p>Simple as it is, the application has some features of the typical + role playing game that frequently just has more states, actions, + possible moves and also provides far richer graphics environment. The + game manger serves as a World-Wide-Pub where you can always find a + partner to play. + + The players can made both unsynchronized (chatting, game reset and + leaving) and synchronized (moves) actions. The game state changes + while playing, and the set of the available actions depends on the + current state. Finally, the mouse and canvas are involved. However + using RMI/IIOP machinery allowed to implement all this functionality + with just 13 classes (plus 4 generated), all of them being rather + simple. + + This example refers to the standard classes only and must be buildable + from your IDE as long as it has any java 1.4 compiler. + </p> + <p> + The used IIOP protocol must ensure interoperability, allowing players + to use different java virtual machines and operating systems. + The processors may have the opposite byte order. + </p> + <h3>Configuration and run + </h3> + <p>The game manager server executable class is + <i>gnu.classpath.examples.CORBA.swing.x5.X5Server + </i>. After start, + it will print to console the Internet address that must be entered to + the client to reach the manager. + </p> + <p>The client executable class it + <i>gnu.classpath.examples.CORBA.swing.x5.Demo + </i>. + </p> + <p>The game should run with GNU Classpath + 0.19 and Sun Microsystems java 1.5.0_04. Due later fixed bugs it will + not run with the older versions of these two implementations. + </p> + <p>The game manager HTTP server uses port + 1500. Hence all firewalls between the server and the player must be + configured to allow HTTP on 1500. The ports, used by the RMI/IIOP are + not persistent. GNU Classpath is configured to take ports 1501, 1502 + and 1503 (the firewalls must allow to use them for RMI/IIOP). The + CORBA implementation other than Classpath may use different port + values. Unfortunately, there is no standard method to configure the + used port range in a vendor-independent way. + </p> + <h3>The game server + </h3> + <p>The game manager is first reachable via http:// protocol (for + instance http://123.456.7.89:1500). The simple server at this port + always serves much longer string, representing the CORBA stringified + object reference (IOR). The + <i>Five-in-a-row + </i>client uses + this reference to find and access the remote game server object. + </p> + <p>If the server player queue is empty, it simply queues this player. + If the queue is not empty, the server introduces the arrived player + and queued player to each other as leaves the them alone. When + playing, the two clients communicate with each other directly, so the + server is just a “meeting point” where the players can + find each other. The game server is a console-only application. + </p> + <p>The initial server http:// address must be transferred to players + by some other means of communication (web chat, E-mail, link in a web + site and so on). The server writes this address to the specified + file, and the client can also take the default value from the same + file. This is convenient when all applications run on a single + machine, but also may be used to transfer the address via shared + filesystem. + </p> + <h3>The game client + </h3> + <p>The clients are Swing-based GUI applications, capable for remote + communication with each other and with the game manager. They have a + set of predefined states and switch between these states in + accordance to the preprogrammed logic. The client states are defined + in the + <i>State + </i> interface. They are displayed in the bottom left + corner of the window and are summarized in the following table: + </p> + <table BORDER=1 CELLPADDING=4 CELLSPACING=0 WIDTH="100%"> + <thead> + <tr BGCOLOR="#ccccff"> + <th BGCOLOR="#e6e6ff"> + Our state + </th> + <th BGCOLOR="#e6e6ff"> + Partner state + </th> + <th BGCOLOR="#e6e6ff"> + Possible actions + </th> + <th BGCOLOR="#e6e6ff"> + Comment + </th> + </tr> + </thead> + <tbody> + <tr> + <td> + Disconnected + </td> + <td> + Partner not accessible + </td> + <td> + Connect + </td> + <td> + Initial state. + </td> + </tr> + <tr> + <td> + Queued + </td> + <td> + Partner not accessible + </td> + <td> + Leave + </td> + <td> + Queued by the game manager. + </td> + </tr> + <tr> + <td> + I think. + </td> + <td> + I wait for your move + </td> + <td> + Make move, reset game, leave, chat. + </td> + <td> + The person who waited for another player to come starts + the game first. + </td> + </tr> + <tr> + <td> + I wait for your move + </td> + <td> + I think + </td> + <td> + Chat, reset game, leave. + </td> + <td> + After the partner makes the move, the state changes to + <i>I think + </i>, unless the end of game situation is detected by + the desk analyzer. + </td> + </tr> + <tr> + <td> + I have lost + </td> + <td> + I have won + </td> + <td> + Chat, reset game, leave. + </td> + <td> + Can be entered with the help of the desk analyzer only. + </td> + </tr> + <tr> + <td> + I have won + </td> + <td> + I have lost + </td> + <td> + Chat, reset game, leave + </td> + <td> + Can be entered with the help of the desk analyzer only. + </td> + </tr> + <tr> + <td> + Error + </td> + <td> + Any + </td> + <td> + Chat, leave + </td> + <td> + This should never happen under normal work, but the demo + program may be modified by the user. + </td> + </tr> + </tbody> + </table> + <br> + <br> + As it is seen, being in one of the states, the client expects to + be the partner client in a certain defined state, and both clients + change they states in a synchronized manner. Each state has its own + set of the available actions and each action either preserves the + current state (chat, reset) or changes it following the rules. For + this simple example, the state change rules are obvious. + <h3>The used RMI-IIOP architecture + </h3> + Both player and game manager servants are derived from the + <i>org.omg.PortableServer.Servant + </i> and, being servants, are simply + connected to the + <i>POA + </i>with + <i>POA.servant_to_reference + </i>. The + first remote object (game manager) is found using the stringified + object reference. No naming service is involved. +</p> +Where required, the CORBA objects are narrowed into required +player and game manager interfaces using method +<i>PortableRemoteObject.narrow(org.omg.CORBA.Object object, Class + interface_class) +</i>, passing the actual interface of the object as +the second parameter. After narrowing, the remote side obtains +possibility to invoke remote methods, defined in the interface of +this object. After the first remote object is found, other objects +can be simply passed as the method parameters. For instance, the game +manager introduces another player by passing its reference as a +parameter to the method +<i>Player.start_game. +</i> +<h3>Class and interface summary +</h3> +<table BORDER=1 CELLPADDING=3 CELLSPACING=0 WIDTH="100%"> + <col> + <col> + <tr> + <th COLSPAN=2 BGCOLOR="#e6e6ff"> + Executables classes + </th> + </tr> + <tr> + <td> + Demo + </td> + <td> + The main executable class of the game client. + </td> + </tr> + <tr> + <td> + X5Server + </td> + <td> + The main executable class of the game manager server. + </td> + </tr> +</table> +<p></p> +<table BORDER=1 CELLPADDING=3 CELLSPACING=0 WIDTH="100%"> + <tr BGCOLOR="#ccccff"> + <th COLSPAN=2 BGCOLOR="#e6e6ff"> + Interface Summary + </th> + </tr> + <tr> + <td> + GameManager + </td> + <td> + The game manager interface. + </td> + </tr> + <tr> + <td> + Player + </td> + <td> + Defines remote methods that are invoked by another player or by + the challenge server. + </td> + </tr> + <tr> + <td> + State + </td> + <td> + Defines the states in that the player can be. + </td> + </tr> +</table> + +<table BORDER=1 CELLPADDING=3 CELLSPACING=0 WIDTH="100%"> + <col> + <col> + <tr BGCOLOR="#ccccff"> + <th COLSPAN=2 BGCOLOR="#e6e6ff"> + Class Summary + </th> + </tr> + <tr> + <td> + _GameManager_Stub + </td> + <td> + Normally generated with rmic compiler, this class represents + the GameManager Stub on the client side. + </td> + </tr> + <tr> + <td> + _GameManagerImpl_Tie + </td> + <td> + Normally generated with rmic compiler, this class represents + the GameManager Tie on the client side. + </td> + </tr> + <tr> + <td> + _Player_Stub + </td> + <td> + Generate with rmic, command line rmic -iiop -poa -keep + gnu.classpath.examples.CORBA.swing.x5.PlayerImpl (the compiled + package must be present in the current folder). + </td> + </tr> + <tr> + <td> + _PlayerImpl_Tie + </td> + <td> + Generate with rmic, command line rmic -iiop -poa -keep + gnu.classpath.examples.CORBA.swing.x5.PlayerImpl (the compiled + package must be present in the current folder). + </td> + </tr> + <tr> + <td> + ChatConstants + </td> + <td> + The chat color code constants, used to indicate who is talking. + </td> + </tr> + <tr> + <td> + ClientFrame + </td> + <td> + The JFrame of the GUI client. + </td> + </tr> + <tr> + <td> + GameManagerImpl + </td> + <td> + The manager connects two players into the game. + </td> + </tr> + <tr> + <td> + IorReader + </td> + <td> + Reads the remote URL. + </td> + </tr> + <tr> + <td> + OrbStarter + </td> + <td> + Starts the ORBs, involved into this application. + </td> + </tr> + <tr> + <td> + PlayerImpl + </td> + <td> + The implementation of the PlayerCommunicator, providing the + local functionality. + </td> + </tr> + <tr> + <td> + PlayingDesk + </td> + <td> + Manages actions, related to the game rules and also does all + painting. + </td> + </tr> +</table> +<h3>See also +</h3> +<p> + <a HREF="http://www.javascripter.net/games/xo/xo.htm">http://www.javascripter.net/games/xo/xo.htm + </a> +</p> +<p> + <a HREF="http://www.leepoint.net/notes-java/45examples/55games/five/five.html">http://www.leepoint.net/notes-java/45examples/55games/five/five.html + </a> +</p> +<p>Copyright +</p> +<p> + <font COLOR="#b3b3b3">Copyright (C) 2005 Free Software Foundation, + Inc.
