Hi guys,

I get this when I load the server.jar in the ampz modpack.
I'm with a host that cannot load both server.jar and forge.jar in the command line.
So how do I work around this or am I not ment to load both jars?
They also said if I provide command line they might add for me.

Hope you can help.

I'm using multicraft and heres my command line to boot the jar:
==================
command = "{JAVA}" -Xmx{MAX_MEMORY}M -Xms{START_MEMORY}M -Djline.terminal=jline.UnsupportedTerminal -Duser.language=en -Duser.country=US -cp forge.jar;"{JAR}" net.minecraft.server.MinecraftServer nogui --nojline --log-strip-color true

{JAR} is the jar file server.jar
=================

I dont think ive ever loaded the forge jar like that, but then again ive never used that pack, but i would assume forge is already in the server jar, so there fore not needed in the startup, try removing "forge.jar;"

hi, i tried just using the server.jar and it didn't work. I believe the jar is just a vanilla copy and the semi colon in the command line merges the forge.jar and vanilla server.jar together. I may be wrong.

Having a similar issue, there isn't really a good crash report from me (unless it is somewhere other than in the minecraft/AMPZ/crash-reports directory. The two reports i have there are useless. Help please.
