Where do I update the PATH environment?

[David Hernandez]

I downloaded what I believe is the J2SE 5.0 from SUN, it installed it in "C:\Program Files\Java\jdk1.5.0_22\", within it, there is a folder called “\bin". Now, the book says "Your need to add an entry to your PATH environment variable that points to the "\bin" directory inside the main Java directory. The" \bin" directory is the one you need a path to so when you type "% javac" at the command line, your terminal will know how to find the javac compiler".

Under "System Properties", "Advance" tab, there ar two groups, the "User Variables" and the "Sys Variables", I guess I could edit the variable PATH variable within the "Sys variables" group, which has the following content :
"%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\" but I am not sure what to edit it to and if I am in the right spot.

Yes. You can also set JAVA_HOME there.

JAVA_HOME = C:\Program Files\Java\jdk1.5.0_22
PATH = "%JAVA_HOME%\bin;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\"

1) JAVA_HOME = C:\Program Files\Java\jdk1.5.0_22

You mean I create a new variable in the "System Variable" group, name it JAVA_Home and the variable value to be C:\Program Files\Java\jdk1.5.0_22?

2)PATH = "%JAVA_HOME%\bin;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\"

You mean I edit the Path variable within the "System Variable" group, add "%JAVA_HOME%\bin;" right before %SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\"?

Thanks.

That's right. Sorry for the confusion.
