I'am 100% it is because when i run it on my win7 it loads without any error or warnings, but on centOS VPS it give me this error? Those it make any difference if i compile the server in the VPS? Because i compiled it and uploaded it to the VPS..

Have you converted your run.bat to run.sh correctly?
Or make sure that the compiled file is in the bin folder.

take a look at this: [URL="http://javarevisited.blogspot.co.uk/2011/06/noclassdeffounderror-exception-in.html"]http://javarevisited.blogspot.co.uk/2011/06/noclassdeffounderror-exception-in.html[/URL] Edited December 5, 2013 by crezzy

This is how the .sh looks like:
[CODE]java -Xmx512m -classpath bin:lib/* dragonkk.rs2rsps.Server[/CODE]
This is how the bat looks like:
[CODE]@echo off
title Running...
"C:\Program Files\Java\jre7\bin\java.exe" -Xmx512m -cp bin;lib/* dragonkk.rs2rsps.Server
pause[/CODE]

You see I compiled the server on my pc and [B][COLOR="#FF0000"]not[/COLOR][/B] on the acctual VPS, but I don't know if thats the case.
And on the VPS it start loading the server, but when it gets to ServerChannelHandler it gives me that error. :/

'NoClassDefFoundError'

Go to bin.dragonkk.rs2rsps.net

See if the ServerChannelHandler is in there.

Umm seems fine. well I just looked the error up for you and this is what it means:
[QUOTE]NoClassDefFoundError in Java comes when Java Virtual Machine is not able to find a particular class at runtime which was available during compile time. For example if we have a method call from a class or accessing any static member of a Class and that class is not available during run-time then JVM will throw NoClassDefFoundError. It’s important to understand that this is different than ClassNotFoundException which comes while trying to load a class at run-time only and name was provided during runtime not on compile time. Many Java developer mingle this two Error and gets confused.

In short NoClassDefFoundError will come if a class was present during compile time but not available in java classpath during runtime. Normally you will see below line in log when you get NoClassDefFoundError:[/QUOTE]

[B]I suggest compiling the server again on the vps[/B]
