Terminal command script

I have recently started running a minecraft server which requires me to type:

java -Xmx1024M -Xms1024M -jar minecraft_server.jar nogui.

into terminal and execute to boot the sever. The command has to be run from the directory which contains the sever files, which seems to be my default terminal location when I open terminal.

My question, is there an easy way to write a script, so I can double click an icon on my desktop and the sever will start?

Open a Terminal and type: nano mcserver.sh (or whatever you want to name it).
When the editor opens, type this:
#!/bin/sh

java -Xmx1024M -Xms1024M -jar minecraft_server.jar nogui

Now type: control-o (that's an O not a zero)
This saves the file. Now type control-x to quit.
Now you need to make it executable. Type chmod +x mcserver.sh
Now you should be able to run it by typing: ./mcserver.sh (notice the ./). Also it's not really necessary to put the .sh if you don't want it.

This is great, thanks. Is there any way to trigger this via an alias/desktop icon?

Use Automator to do it. I dont have it in front of me, but you can set up a shell script as an app.

check this post. different script, but the steps are the same.

Assume I am a complete idiot (mostly true where scripting on mac is concerned). I like the automator approach, but it doesn't seem to like the 'boot' command.

I have opened automator with a 'do shell script' window. Shell is set to /bin/bash and pass input is set to 'to stdin'

In my command/script entry window I have:

cd /Users/James/Desktop/Server
java -Xmx1024M -Xms1024M -jar minecraft_server.jar nogui
say "server booted"

The command has to be run from the directory where the server files are contained, hence the cd command. When tested or run outside automator it seems to do nothing. When the test application is stopped inside automator the say command triggers.

**Edit**
After rebooting (which closed java) the automator script worked fantastically. Thanks for the help
