I can't find "javac"

Question

I am having a hard time fixing this problem. I downloaded JDK 1.6.0_22 and I am using Windows Vista Home Premium edition and when I try to run the "javac HelloWorlApp.java" I get the error: 'javac' is not recognized as an internal or external command, operable program or batch file
I went back and read the directions and also the troubleshooting page with a similar example and created this path:
To set the PATH permanently, add the full path of the jdk1.6.0_<version>\bin directory to the PATH variable. Typically this full path looks something like C:\Program Files\Java\jdk1.6.0_<version>\bin. Set the PATH as follows on Microsoft Windows:
1.Click Start > Control Panel > System on Windows XP or Start > Settings > Control Panel > System on Windows 2000.
2.Click Advanced > Environment Variables.
3.Add the location of bin folder of JDK installation for PATH in User Variables and System Variables. A typical value for PATH is:
C:\Program Files\Java\jdk1.6.0_<version>\bin
I still can't find/run the "javac" command but the computer cannot find it.
Any advice? Thanks...

Answer 1

Hi guys, thanks for the information. I removed the files I added to the bin folder and put them back in my documents. I followed the instructions here:
http://download.oracle.com/javase/tutorial/getStarted/cupojava/win32.html#win32-2b
and I can't run "javac" from the java directory. It gives me the same error. I copied what I get from the command screen here:

After this I went to the troubleshooting section and tried to update the PATH in the Variable Environment.
Kate, you asked what I put in step three, here it is:
In the variable environment I found two boxes: the user variables and the system variables. I clicked "NEW" in the user section and a box came up with two fields:
1- variable name: javac
2- variable value: C:\Program Files\Java\jdk1.6.0_22\bin then I repeated the same steps in the System variable.
Any ideas or recommendations?
Thanks again for all the help!!
Richard.
