I can't seems to figure out why i get this error.

But I used to run a minecraft 1.5.1 server with forge. Which gave me no problem at all.

Then the new 1.5.2 came out and i went and got the new server.jar file.

Then i downloaded the newest Forge for Minecraft 1.5.2 and installed it.

And when i'm trying to start my server, it says that my server.jar is corrupt.

I then figured out that its because i'm deleting the META-INF folder in my server.jar

But as i can read in the Readme file, then i have to delete it.

 

What can i do to make this work?

No you don't, if you run a server you run the forge zip as a jar.

So what are you saying.

That the readme file is not correct at all?

Cause it says the following:

 

Installation

============

 

To install this on it's own into a minecraft environment, simply copy the

contents of the fml zip file into the minecraft jar file, using your preferred

zip management tool (I recommend 7 zip on windows).

 

For servers: the minecraft jar file is minecraft_server.jar.

For clients: the minecraft jar file is minecraft.jar.

 

You will additionally need

to delete the "META-INF" folder in the minecraft.jar file.

 

==============

 

 

 

The readme file is incorrect - cpw revised the build process to be able to achieve this.
