After adding the directory "C:\Program Files\Java\jdk1.6.0_16\bin\" to the end of the environment path variable, the java command works fine, but using javac gives me the error: 'javac' is not recognized as an internal or external command, operable program or batch file.

You'll need to exit and re-open or simply do: set path="%path%;c:\program files\java\jdk1.6.0_16\bin" By way of checking, execute: echo %path% from your command prompt and let us know what it is. Otherwise, make sure there is a javac in that directory by trying: "c:\program files\java\jdk1.6.0_16\bin\javac.exe" from the command prompt. You can also tell which executable (if any) is being used with the command: for %i in (javac.exe) do @echo %~$PATH:i This is a neat trick similar to the which and/or whence commands in some UNIX-type operating systems. share|improve this answer edited Nov 5 '09 at 5:46 answered Nov 5 '09 at 5:29 paxdiablo 491k1189731422 5 ah yes, all i had to do was re-open the command prompt and it worked fine, thanks! –Domenic Nov 5 '09 at 6:02 1 +1. The "for %i in (java.exe) do @echo %~$PATH:i" just saved my day. I'm just a occasional Windows use

First, what do you mean by "not able to download Java"? What exactly is happening when you try? Second, why are you trying to set the CLASSPATH? (Especially if you were not able to download Java.) You should be updating the PATH, but you should probably not be setting a CLASSPATH. When you download JDK 6 Update 5, be sure to follow the installation instructions, which will tell you how to update the PATH variable. "We're kind of on the level of crossword puzzle writers...
