Line 161 ⟶ 175:
Marauroa frameword provides the main method for server, so that you don't need to care about execution loop. It is not true for server, so we will also need to implement the main module of our client. Here is a very easy solution
<source lang="java">
import java.io.IOException;
import java.lang.Thread;
 
import marauroa.common.Log4J;
import marauroa.common.game.RPAction;
import marauroa.common.game.RPObject;
 
public class Test {
public static void main(String[] args) {
boolean condrunClient = true;
Client myclient = Client.get();
try {
myclient.connect("localhost", 5555);
if (args.length == 3) {
myclient.createAccount(args[0], args[1], args[2]);
}
myclient.login(args[0], args[1]);
if (myclient.GetAvailableCharactersgetAvailableCharacters().length == 0) {
RPObject character = new RPObject();
myclient.createCharacter(args[0], character);
}
myclient.chooseCharacter(args[0]);
} catch (Exception e) {
condrunClient = false;
}
int i = 0;
while (condrunClient) {
i++i;
myclient.loop(0);
if (i % 100 == 50) {
myclient.SendMessagesendMessage("test" + i);
}
String s = myclient.popQuote();
while (s != null) {
System.out.println(s);
s = myclient.popQuote();
}
try {
Thread.sleep(100);
} catch (InterruptedException e) {
condrunClient = false;
}
}
Line 224 ⟶ 233:
java -cp marauroa.jar;log4j.jar;. Test login password
</pre>
Again, on Linux & MacOSX, all ";" have to be replaced with ":".
 
Don't forget to replace login and password with the actual ones. To create a new account just add a third command-line parameter (that should be an email, but no validation at the moment).
Line 232 ⟶ 242:
>java -cp marauroa.jar;log4j.jar;. Test test1 test1
Cannot find log4j.properties in classpath. Using default properties.
0.5
Do not contact us!
Marauroa server
Chat
*test1* : test50
*test1* : test150
*test1* : test250
...
</pre>
 
Note the message about log4j.properties: you can create that file in order to configure the Log4J usage inside the Marauroa framework.
 
== Next Steps ==
 
In the next section of this tutorial, we will write a '''[[Marauroa Chat Tutorial/Swing Client|Swing client]]''' with a graphical user interface.
