Java application is not working in Win 7 64-bit

Question

I have a program that runs a command "java ---.jar", which stopped running when I upgraded to 64-bit Win 7.  When I go to command prompt, and type "java -version" for example, I get the error message "'java' is not recognized as internal or external command, operable program or batch file."  I suspect that this is an issue peculiar to the 64-bit version, because my laptop that is running a 32-bit version of Win 7 responds to this command very nicely.  I tried installing 64-bit version, and later 32-bit version of Java console, but neither works.  Your help will be greatly appreciated.  Hiroshi
