Do you get Karma for answering your own questions? I've started the server using "exec java -verbose -Xmx1G -Xms1G -cp minecraft_server.jar net.minecraft.server.MinecraftServer" When using the command line jar utility my resulting .jar file had a new manifest that contained: Manifest-Version: 1.0 Created-By: 1.6.0_33 (Apple Inc.) Instead of the original: Manifest-Version: 1.0 Main-Class: net.minecraft.server.MinecraftServer More practice is in my future; I was on the right track earlier attempting to rebuild the manifest from a supplied text file but got confused on what the last parameter did. Thanks again Texasjake95; that was enough of a hint for me to dig in a bit further and figure it out. -JD

Sorry, I was not clear. I have tried all of these steps twice. Pass One without deleting META-INF Pass Two with deletion of META-INF Same results in both cases. Thanks for the timely reply. It also helps narrow it down to before the step when the manifest would be evaluated so that eliminates a lot of noise.

I'm certain this is an invalid operator error; I would appreciate any guidance you could provide to help me narrow down the root cause. I'm attempting to manually install minecraftforge-server-3.3.7.135 into a vanilla minecraft_server.jar I've followed the instructions at http://minecraftforge.net/wiki/Installation/Server I'm working on a MAC running OS 10.7.4 with Java 1.6.0_33 I've manually extracted the minecraft_server.jar file to a working folder. And done the same for minecraftforge-server-3.3.7.135. zip I then copied the Forge files to server files and verified that everything copied. I packaged it back up. Moved the server file into place and ran it. It did not execute far enough to generate a ModLoader.txt (assuming it still will being integrated) and the stack trace info I have is above in spoilers. I downloaded a fresh minecraftServer.jar file, ran the file before extracting to ensure it worked then completed the steps described above. In looking through the previous posts and searching other sources, the only way to generate a "Failed to load Main-Class manifest attribute from minecraft_server.jar" error is for the manifest to be messed up or for files to be missing. I've retried all of this deleting the META-INF folder per earlier comments about installing mod loader as a dependancy. Thoughts on where to go next? Back to school is a valid answer, but I'm hoping for something a little more tactical. Thanks. JD
