1. Download CraftBukkit's latest recommended build.
2. Put the .jar in the desired directory
3. Open notepad and type: 
   

@ECHO OFF 
 SET BINDIR=%~dp0 
 CD /D "%BINDIR%" 
 "%ProgramFiles%\Java\jre6\bin\java.exe" -Xincgc -Xmx1G -jar craftbukkit-0.0.1-SNAPSHOT.jar 
 PAUSE 
 

 Note: If you are running java in 32bit mode on a 64bit machine, change %ProgramFiles% to %ProgramFiles(x86)%

If you are running Java 7 beta, type instead:

@ECHO OFF 
 SET BINDIR=%~dp0 
 CD /D "%BINDIR%" 
 "%ProgramFiles%\Java\jre7\bin\java.exe" -Xincgc -Xmx1G -jar craftbukkit-0.0.1-SNAPSHOT.jar 
 PAUSE 
 

4. Save the document as RUN.bat (not as a .txt)

5. Double Click RUN.bat and you're away!

6. When you're done toying, issue "stop" command in console.

Please note that the full directory of the java.exe does not need to be entered. just entering "Java" will do just fine, so one could use the following codes to ensure universal compatibility.

@ECHO OFF 
 SET BINDIR=%~dp0 
 CD /D "%BINDIR%" 
 java -Xincgc -Xmx1G -jar craftbukkit-0.0.1-SNAPSHOT.jar 
 PAUSE 

 

Or, the following can be used (although may not work on all machines) It is a lot shorter than the previous ones.

@ECHO OFF 
 java -Xincgc -Xmx1G -jar "%dp0craftbukkit-0.0.1-SNAPSHOT.jar" 
 PAUSE
