KingOfTheKey

I'm having issues trying to get any mod to work with forge I've tried several times getting a brand new minecraft_server.jar but it won't help Maybe I'm doing something wrong... I download minecraft_server.jar, open it with winrar drag all the files from forge into it (I'm using the recommended build from http://www.minecraftforge.net/forum/index.php/topic,5.0.html) I then start the server and everything works fine. It creates a mod and coremods folder. Now I try to put a mod in the mod folder and start the server and I keep getting error messages along the lines of this [sEVERE] Encountered an unexpected exception LoaderException cpw.mods.fml.common.LoaderException: java.lang.ClassNotFoundException: dungeonpack.DungeonPack at cpw.mods.fml.common.LoadController.transition(LoadController.java:102) at cpw.mods.fml.common.Loader.loadMods(Loader.java:467) at cpw.mods.fml.server.FMLServerHandler.beginServerLoading(FMLServerHandler.java:80) at cpw.mods.fml.common.FMLCommonHandler.onServerStart(FMLCommonHandler.java:340) at ft.b(DedicatedServer.java:49) at net.minecraft.server.MinecraftServer.run(MinecraftServer.java:433) at ep.run(SourceFile:539) Caused by: java.lang.ClassNotFoundException: dungeonpack.DungeonPack at cpw.mods.fml.relauncher.RelaunchClassLoader.findClass(RelaunchClassLoader.java:125) at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at cpw.mods.fml.common.ModClassLoader.loadClass(ModClassLoader.java:57) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Unknown Source) at cpw.mods.fml.common.FMLModContainer.constructMod(FMLModContainer.java:407) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at com.google.common.eventbus.EventHandler.handleEvent(EventHandler.java:69) at com.google.common.eventbus.SynchronizedEventHandler.handleEvent(SynchronizedEventHandler.java:45) at com.google.common.eventbus.EventBus.dispatch(EventBus.java:317) at com.google.common.eventbus.EventBus.dispatchQueuedEvents(EventBus.java:300) at com.google.common.eventbus.EventBus.post(EventBus.java:268) at cpw.mods.fml.common.LoadController.propogateStateMessage(LoadController.java:124) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at com.google.common.eventbus.EventHandler.handleEvent(EventHandler.java:69) at com.google.common.eventbus.SynchronizedEventHandler.handleEvent(SynchronizedEventHandler.java:45) at com.google.common.eventbus.EventBus.dispatch(EventBus.java:317) at com.google.common.eventbus.EventBus.dispatchQueuedEvents(EventBus.java:300) at com.google.common.eventbus.EventBus.post(EventBus.java:268) at cpw.mods.fml.common.LoadController.distributeStateMessage(LoadController.java:81) at cpw.mods.fml.common.Loader.loadMods(Loader.java:466) ... 5 more Caused by: java.lang.NullPointerException at org.objectweb.asm.ClassReader.<init>(Unknown Source) at cpw.mods.fml.common.asm.transformers.SideTransformer.transform(SideTransformer.java:27) at cpw.mods.fml.relauncher.RelaunchClassLoader.runTransformers(RelaunchClassLoader.java:162) at cpw.mods.fml.relauncher.RelaunchClassLoader.findClass(RelaunchClassLoader.java:118) ... 32 more [sEVERE] This crash report has been saved to: C:\Users\Tristan\Desktop\serv\.\crash-reports\crash-2012-10-17_05.58.30-server.txt Obviously some of that is mod specific but I keep getting the same error with every mod. Here's some links to some of the mods I've tried to install and still got similar messages. http://www.minecraftforum.net/topic/1340914-132smpbukkitforgedungeonpack22-dungeonsboss2-npc-villages-v4-5-new-dungeons/ http://www.minecraftforum.net/topic/1152139-minecraft-132-netherrocks-mod-ssp-smp/ http://www.minecraftforum.net/topic/1478978-132-extended-items-mod-extended-foods-mod-6k-downloads/ I've tried many more and all give the same error. I'm using a standard vanilla server, and I've tried fresh everything with almost every one of these mods.
