How to make a runescape private server?

i did all thath stands there but when i click runclient it wont open and when i try a moparscape webclient it wont work

Guys, To fix your problem:
When you edit the compiler and paste the text, the beginning looks like this:
@echo off
if exist "C:\Program Files (x86)\" set programfiles=C:\Program Files (x86)
set pro=%programfiles%\Java\jdk1.6.0_2
set pro2=%programfiles%\Java\jdk1.6.0_2
set jac=\bin\javac.exe
set jav=\bin\java.exe

3rd and 4th line says: jdk1.6.0_2 - this is your Java version. If you downloaded (for example) java update 14, you only have to chage the _2 to _14 and it will work. Check your java version and just change it ;)

ok, it says find the server name, but when do I add a server name in the first place?
