Posted December 14, 201311 yr I am trying to run a forge server with forge 6.4.45.951(Yes, I know it isn't the newest version of forge.) It works great when I run it on client and LAN but it gives an error for a dedicated sever. 2013-12-14 16:22:31 [sEVERE] [Minecraft-Server] Encountered an unexpected exception NoClassDefFoundError java.lang.NoClassDefFoundError: org/lwjgl/LWJGLException at net.minecraft.server.management.PlayerManager.<init>(PlayerManager.java:55) at net.minecraft.world.WorldServer.<init>(WorldServer.java:113) at net.minecraft.server.MinecraftServer.func_71247_a(MinecraftServer.java:246) at net.minecraft.server.dedicated.DedicatedServer.func_71197_b(DedicatedServer.java:187) at net.minecraft.server.MinecraftServer.run(MinecraftServer.java:445) at net.minecraft.server.ThreadMinecraftServer.run(SourceFile:583) Caused by: java.lang.ClassNotFoundException: org.lwjgl.LWJGLException at java.net.URLClassLoader$1.run(Unknown Source) at java.net.URLClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at net.minecraft.launchwrapper.LaunchClassLoader.findClass(LaunchClassLoader.java:102) at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) ... 6 more
December 15, 201311 yr Simple, one of the mods you have installed is not server compatible. I do Forge for free, however the servers to run it arn't free, so anything is appreciated. Consider supporting the team on Patreon
