Hi All! I can not understand in what problem. I put Server T2.4 on Ubuntu 10.04.
Has installed java version "1.6.0_21".
At start startLoginServer.sh in stdout.log writes:

Exception in thread "main" java.lang.NoClassDefFoundError: org/mmocore/network/IAcceptFilter
Caused by: java.lang.ClassNotFoundException: org.mmocore.network.IAcceptFilter

Could not find the main class: com.l2jserver.loginserver.L2LoginServer. Program will exit.

lib folder absent, or not in the class path.
l2jlogin.jar absent.

And how it to correct? More in detail

it means you have incomplete files...

Why it not the full? On Windows server 2003 it is the assembly it is normal it is launched and on ubuntu here such problem.

if linux... probably permission issues.

For this purpose it is necessary to edit LoginServer_loop.sh? At me there I can't understand it what there to write...
