Hello Everyone, Just set up my Bukkit Server last night. I was running the basic server from MineCraft.net. 1) I installed Bukkit following the tutorial on the Wiki. 2) I moved over my world folder to my new server location and was able to run and log in. 3) Some people can log on, a few however crash the server with error: [SEVERE] Unexpected exception java.lang.NullPointerException at net.minecraft.server.Explosion.<init>(Explosion.java:47) at net.minecraft.server.World.a(SourceFile:1300) at net.minecraft.server.WorldServer.a(WorldServer.java:99) at net.minecraft.server.World.a(SourceFile:1296) at net.minecraft.server.EntityTNTPrimed.d(EntityTNTPrimed.java:70) at net.minecraft.server.EntityTNTPrimed.b_(EntityTNTPrimed.java:61) at net.minecraft.server.World.a(SourceFile:1116) at net.minecraft.server.WorldServer.a(WorldServer.java:41) at net.minecraft.server.World.f(SourceFile:1092) at net.minecraft.server.World.c(SourceFile:1071) at net.minecraft.server.MinecraftServer.h(MinecraftServer.java:260) at net.minecraft.server.MinecraftServer.run(MinecraftServer.java:197) at net.minecraft.server.ThreadServerApplication.run(SourceFile:512) Also, When anyone places Minecarts they get a client crash and error in console: [WARNING] Failed to handle packet: java.lang.ClassCastException: org.bukkit.craftbukkit.entity.CraftEntity cannot be cast to org.bukkit.entity.Vehicle java.lang.ClassCastException: org.bukkit.craftbukkit.entity.CraftEntity cannot be cast to org.bukkit.entity.Vehicle at net.minecraft.server.EntityMinecart.handleCreation(EntityMinecart.java:177) at net.minecraft.server.EntityMinecart.<init>(EntityMinecart.java:136) at net.minecraft.server.EntityMinecart.<init>(EntityMinecart.java:160) at net.minecraft.server.ItemMinecart.a(ItemMinecart.java:37) at net.minecraft.server.ItemStack.a(ItemStack.java:56) at net.minecraft.server.ItemInWorldManager.a(ItemInWorldManager.java:124) at net.minecraft.server.NetServerHandler.a(NetServerHandler.java:447) at net.minecraft.server.Packet15Place.a(SourceFile:57) at net.minecraft.server.NetworkManager.a(SourceFile:232) at net.minecraft.server.NetServerHandler.a(NetServerHandler.java:65) at net.minecraft.server.NetworkListenThread.a(SourceFile:104) at net.minecraft.server.MinecraftServer.h(MinecraftServer.java:261) at net.minecraft.server.MinecraftServer.run(MinecraftServer.java:197) at net.minecraft.server.ThreadServerApplication.run(SourceFile:512) Restart of PC and server didn't fix either. The first error is my Priority. I also tried increasing the ram using the -Xmx1024M -Xms1024M (that by memory, may not be exact). -I am running 32 bit on Windows as Administrator. -Java installed v6 b23 -The build I am running is called 0.0.1 but I do not know how to get more information on the Bukkit Build. -Plugins Installed: plugins=Permissions,General,dynmap,CodeRedEconomy, -Plugins that were installed but I have removed: interest,MagicCarpet I do not want to create a whole new world. So any suggestions would be great. I am new to Bukkit and Java so please speak in laymen's terms. I did search the forum and google for my errors - couldn't find much (or at least understand it). Thank you in advance for any assistance. So, I kept looking into this. Appears the build last night had this error and it is fix today in build 126. Downloaded the new .jar from http://bamboo.lukegb.com/browse/BUKKIT-CRAFTBUKKIT under #126 -> artifacts. Fixed the Log On issue and TNT issue. Looking into the Minecarts now. Thanks everyone for all the posts in the other Threads. Was really helpful. EDIT by Moderator: merged posts, please use the edit button instead of double posting.
