Hi,

I would like to try Jetserver. However, I have some problems as followings:

1) Test failed

When test jetserver, both directly from eclipse or from command line (I run mvn clean install, then mvn test in MacOS) all failed:

2) How to run server (and then any client/example)?

I found the jar file jetserver-0.1.jar in the subfolder binaries of jetserver but don't know how to run it. I have tried java -cp ./jetserver-0.1.jar -Dlog4j.configuration=GameServerLog4j.properties org.menacheri.GameServer but got exception "Exception in thread "main" java.lang.NoClassDefFoundError: org/menacheri/GameServer".

I have checked and can't find class GameServer.

Please help. Many thanks!

Hi Tony,

Thanks for your interest in jet server. I think you might be using an older version of binary. The latest binaries are available in maven central itself. Just search for "nadron" you can either download or use it the same way example-games project is using it via its pom.xml

To run from eclipse(Note, i have not tried it on mac) you need to go to example-games project (use the netty4 branch) since that is the latest branch and execute the io.nadron.GameServer. This is the main class, please ensure that you pass -Dlog4j.configuration=GameServerLog4j.properties in the vm parameters of eclipse to ensure it runs properly.

Now you should have the server running. For running the java client (note there is java client, flash client and web socket client) of the Zombie game, please use the ZombieNadClient file. You should now see the logs of zombie and human population going up and down.

For websocket and a more detailed explanation please see the following post http://nerdronix.blogspot.com/2013/06/creating-multiplayer-game-using-html-5.html on my blog.

Thanks,

Abraham

Thanks a lot Menacherry for creating JetServer and very fast responding :)

I see the reason I cannot compile the example is maven dependency. The code requires jetserver.jar and jetclient.jar which are not available on both com.github.menacher and org.menacheri. After adding nadron dependancy into the pom file, I have found nadron-0.5.jar on the repository of maven but the code still has errors and I don't know how to change code to use that.

For a quick try, I have copied both jetserver-0.1.jar and jetclient-0.1.jar which I found from banaries folder of jetserver/jetclient into a folder then add them as jar libraries into project example-games. Now I can run both server and client as normal java application and can read info from GameServer.log as you mentioned above.

Question:

- How can I create and use nadron.jar instead of jetserver/jetclient? It looks like all code will create and use jet server/client but not nadron. It is the best if you update all code

I always highly appreciate your works and helps.

Sorry, that is my mistake. I have downloaded and tried the old version JetServer.

After downloading nadron, I can run maven test for nadron succesfully.

However, when starting server of example-games (run as normal Java application from eclipse), it stops immediately and bellow is the content of GameServer.log about permission. My computer (MacBookPro) has no firewall.

Can you advice me how to fix that problem? Many thanks
