Ok open your source folder. Right click the compiler, and click edit. When a notepad document comes up, delete everything on there and put this:
@ECHO OFF
title Server
"C:\Program Files\Java\jdk1.X.0_XX\bin\javac.exe" -cp . *.java
pause
Ok so now you need to edit the X's.
You change the first X to whatever the first number of JDK yours is. If you have JDK 6.X put a six in the first X. Put Five in if you have JDK 5.X
Example for JDK 6.X
@ECHO OFF
title Server
"C:\Program Files\Java\jdk1.6.0_XX\bin\javac.exe" -cp . *.java
pause
For the two X's after that, put the ".XX" that your JDK is. From the screenies it looks like you downloaded JDK 5.15 right? So your source should now look like this.
@ECHO OFF
title Server
"C:\Program Files\Java\jdk1.5.0_15\bin\javac.exe" -cp . *.java
pause
If you have a single digit number instead of a number like "15" put a 0 before it so since I have JDK 6.6 my source will look like this.
@ECHO OFF
title Server
"C:\Program Files\Java\jdk1.6.0_06\bin\javac.exe" -cp . *.java
pause
If you are still having trouble ill post screenies.
