Adding Java to Windows 7 PATH

Java is actually installed on my Windows 7 system, but is not showing up when I try "java -version" on the command prompt.

So looks like the JRE bin directory is not included in the system path. What you want to do is right-click on MyComputer and select Properties. Click Advanced system settings. Under the Advanced tab, click Environment Variables. Under System variables, scroll down until you find the PATH variable. Select it and click Edit. Add in the JRE bin path, and click OK.
