How do you Update A Server?

I have no clue what to do, I have downloaded the recommended build for the new minecraft update. Which is Minecraft 1.2 All I know is that I have to change the .Bat file to Start the server. I have tried to update it a couple hours ago, but that did not work. Now when I try to reverse it to what it was before It will not work either. Here is the .bat text
Echo OFF
SET BINDIR=%~dp0
CD /D "%BINDIR%"
"%ProgramFiles(x86)%\Java\jre6\bin\java.exe" -Xincgc -Xmx1G -jar craftbukkit-1.1-R4
PAUSE




Please help me

 

craftbukkit-1.1-R4

Change it to craftbukkit-1.1-R6

Rename the R6 .jar server file to JUST craftbukkit-1.1-R6

Done.

 

Well isnt that For minecraft 1.1 though?
*Edit - I tried it and it it says unable to access jarfile craftbukkit1.1-R6

 

I think it should be craftbukkit-1.1-R6.jar

And yes this is for minecraft 1.1 but there are no recommended build for minecraft 1.2 yet. Download the latest dev build here.

btw where it says craftbukkit-1.1-R4 in your bat that should be the exact same as the name of your craftbukkit

I made sure the .bat Is exactly the same as the Name of the Jarfile found in that Link

Echo OFF
SET BINDIR=%~dp0
CD /D "%BINDIR%"
"%ProgramFiles(x86)%\Java\jre6\bin\java.exe" -Xincgc -Xmx1G -jar craftbukkit-1.2.3-R0.1-20120302.201
PAUSE

What am I still doing wrong?
and can having other jar files in the Server Folder hinder it in anyway?

 

@Echo OFF
SET BINDIR=%~dp0
CD /D "%BINDIR%"
"%ProgramFiles(x86)%\Java\jre6\bin\java.exe" -Xincgc -Xmx1G -jar craftbukkit-1.2.3-R0.1-20120302.201.jar
PAUSE
