Thank you for your time.
Caused by: java.lang.ClassNotFoundException: net.minecraft.server.v1_8_R2.Packet This means that the plugin you are trying to load, is not able to find a piece of code in the server that it is supposed to look for, which means that the plugin is either missing a plugin it is dependant on (usually this will indicaate the other plugin name it is missing though) or that plugin version you have was written for a DIFFERENT server version than what you have, as the server version you have does not contain the code that the plugin is looking for. This could be because the plugin version is too old for the server version you have, or the plugin version is too NEW for the server build you are using. You need to find a version that will work on your server version.
Disguise Craft Is a VERY hit and miss plugin. I WAS using it- but it gave me so many errors, lag outs and issues I got rid of it (Once one of my Mod's got glitched & stuck as a Ghast, and every time he'd log in- He was still a Ghast until I took the plugin out and re installed it). The Current version (v5.1) of DC Is only meant to run for MC Server Builds for 1.8.1- but I was only ever about to get mine to run without issues on server builds 1.8.6 and 1.8.7- but Disguise Craft broke with the new 1.8.8 update. It no longer works with ANY 1.8.8 server for ANY version available. And sadly, it's been Months since the devs have had any real activity in the way of updates for it, so I wouldn't expect a fix any times soon. So if you wanna use DC, I suggest running a server build between 1.8.1 and 1.8.7 Or finding a farther backdated version like @Boomer said
Thank you very much for the replies, My server appears to be 1.7.10 and higher and I downloaded DisguiseCraft 1.8.3. based off of that can you tell me what to do? sorry Im still confused.
You'll Need To update your server to a more recent build. I'd suggest switching to Spigot: https://www.spigotmc.org/ It's pretty much the same things as Bukkit, Most all of the plugins are cross compatible, but Spigot is still updating, so It's not running on 1.8.8 But if you want to use disguise craft, I'd suggest aiming for a 1.8.7 server If updating isn't something you want to do, hop on the Disguise craft page and see how old of a download you can get for the plugin
you do not HAVE to upgrade from 1.7.10 to 1.8.x You CAN download the CORRECT version of the disguize plugin that will work on a 1.7.10 server
...and the protocollib file you have, is IT the right version? Having a wrong version of any plugin that prevents being loaded results in it being as if that plugin wasn't on the server, so "I have the file" means squat compared to "I have the right version for my server on my server" Pastebin.com your entire latest.log file from a fresh server start, entire file as soon as it finishes booting up.
Yes I have the right Protocollib file it is CB 1.7.9-R0.1 But they don't have DisguiseCraft CB 1.7.10-R0.1
Problem-solving options are exhausted, conclusion is final: you can't use that plugin with your server version. It actually looks like that plugin died years ago, but was then revived recently. There will be alternative plugins that filled the gap in a similar function in between
I thank you very much for all your help and time put into this I will try my best to figure this out. -Pineappleaz I got a spigot 1.8 with 1.8 items and I got this for DisguiseCraft Code: [18:44:56 ERROR]: Could not load 'plugins/DisguiseCraft-5.jar' in folder 'plugins' org.bukkit.plugin.InvalidPluginException: java.lang.NoClassDefFoundError: net/minecraft/server/v1_8_R2/Packet at org.bukkit.plugin.java.JavaPluginLoader.loadPlugin(JavaPluginLoader.java:135) ~[spigot.jar:git-Spigot-fdc1440-53fac9f] at org.bukkit.plugin.SimplePluginManager.loadPlugin(SimplePluginManager.java:329) ~[spigot.jar:git-Spigot-fdc1440-53fac9f] at org.bukkit.plugin.SimplePluginManager.loadPlugins(SimplePluginManager.java:251) [spigot.jar:git-Spigot-fdc1440-53fac9f] at org.bukkit.craftbukkit.v1_8_R3.CraftServer.loadPlugins(CraftServer.java:292) [spigot.jar:git-Spigot-fdc1440-53fac9f] at org.bukkit.craftbukkit.v1_8_R3.CraftServer.reload(CraftServer.java:739) [spigot.jar:git-Spigot-fdc1440-53fac9f] at org.bukkit.Bukkit.reload(Bukkit.java:535) [spigot.jar:git-Spigot-fdc1440-53fac9f] at org.bukkit.command.defaults.ReloadCommand.execute(ReloadCommand.java:25) [spigot.jar:git-Spigot-fdc1440-53fac9f] at org.bukkit.command.SimpleCommandMap.dispatch(SimpleCommandMap.java:141) [spigot.jar:git-Spigot-fdc1440-53fac9f] at org.bukkit.craftbukkit.v1_8_R3.CraftServer.dispatchCommand(CraftServer.java:641) [spigot.jar:git-Spigot-fdc1440-53fac9f] at org.bukkit.craftbukkit.v1_8_R3.CraftServer.dispatchServerCommand(CraftServer.java:627) [spigot.jar:git-Spigot-fdc1440-53fac9f] at net.minecraft.server.v1_8_R3.DedicatedServer.aO(DedicatedServer.java:412) [spigot.jar:git-Spigot-fdc1440-53fac9f] at net.minecraft.server.v1_8_R3.DedicatedServer.B(DedicatedServer.java:375) [spigot.jar:git-Spigot-fdc1440-53fac9f] at net.minecraft.server.v1_8_R3.MinecraftServer.A(MinecraftServer.java:653) [spigot.jar:git-Spigot-fdc1440-53fac9f] at net.minecraft.server.v1_8_R3.MinecraftServer.run(MinecraftServer.java:556) [spigot.jar:git-Spigot-fdc1440-53fac9f] at java.lang.Thread.run(Thread.java:695) [?:1.6.0_65] Caused by: java.lang.NoClassDefFoundError: net/minecraft/server/v1_8_R2/Packet at java.lang.Class.forName0(Native Method) ~[?:1.6.0_65] at java.lang.Class.forName(Class.java:249) ~[?:1.6.0_65] at org.bukkit.plugin.java.PluginClassLoader.<init>(PluginClassLoader.java:64) ~[spigot.jar:git-Spigot-fdc1440-53fac9f] at org.bukkit.plugin.java.JavaPluginLoader.loadPlugin(JavaPluginLoader.java:131) ~[spigot.jar:git-Spigot-fdc1440-53fac9f] ... 14 more Caused by: java.lang.ClassNotFoundException: net.minecraft.server.v1_8_R2.Packet at org.bukkit.plugin.java.PluginClassLoader.findClass(PluginClassLoader.java:91) ~[spigot.jar:git-Spigot-fdc1440-53fac9f] at org.bukkit.plugin.java.PluginClassLoader.findClass(PluginClassLoader.java:86) ~[spigot.jar:git-Spigot-fdc1440-53fac9f] at java.lang.ClassLoader.loadClass(ClassLoader.java:306) ~[?:1.6.0_65] at java.lang.ClassLoader.loadClass(ClassLoader.java:247) ~[?:1.6.0_65] at java.lang.Class.forName0(Native Method) ~[?:1.6.0_65] at java.lang.Class.forName(Class.java:249) ~[?:1.6.0_65] at org.bukkit.plugin.java.PluginClassLoader.<init>(PluginClassLoader.java:64) ~[spigot.jar:git-Spigot-fdc1440-53fac9f] at org.bukkit.plugin.java.JavaPluginLoader.loadPlugin(JavaPluginLoader.java:131) ~[spigot.jar:git-Spigot-fdc1440-53fac9f] Also Essentials Didn't work either!? EDIT by Timtower: merged posts
Did you get Essentials for 1.8 too? If not, get it here: http://hub.spigotmc.org/jenkins/job/Spigot-Essentials/ And when you updated your server version, did you get DisguseCraft version 5.1? http://dev.bukkit.org/bukkit-plugins/disguisecraft/files/51-v5-1/ This plugin seems to be a possible alternative, you could give it a look if you'd like: http://dev.bukkit.org/bukkit-plugins/idisguise/

how do I get java 7???

Get the right essentials Stop trying to launch DisguiseCraft-5.1.jar because that error means "This plugin version will not work ever on this server build version EVER EVER" and find a different version or functional solution for your version.
And the specific exact build version that you upgraded to is off just enough for the plugin version you have... There is some version of 1.8 that it would work on, but not yours, sadly. It is impossible to make something work that will not work. Its not just a matter of applying some duct-tape to get a square hose to fit on a round tube and have a working solution - disguise plugins are VERY specific to server builds because they use a process called 'reflection' which looks for specifically named server code within the server files, code which changes each and every version and thus must be matched. The only fix is to fix and recompile the plugin for the different systems.
