In windows 7 CMD, I want to execute the command `%JAVA_HOME%\bin\keytool -genkey -alias tomcat -keyalg RSA`. This command is not the main thing.

So, for this I created `JAVA_HOME` system variable with value `C:\Program Files\Java\jdk1.6.0_10`. Then, I created a user variable `PATH` = `%JAVA_HOME%`\bin. I did NOT
restart my computer. I also tried one more thing - delete user variable `PATH` and then 
put `;%java_home%\bin` inside an already existing system variable called `Path`.

Now, when I execute the cmd command, I get an error - `the system cannot find the path specified`. I use eclipse and stopped using javac, cmd etc. a long time ago. How do I make this work ?
