Hello,
After you have unzipped the zipped JDK did you updated your PATH?
If you just unzip the JDK and you try to use javac.exe or java.exe outside the bin directory of the jdk then it won't work unless you
a) update your PATH to include the bin directory, or
b) you specify the path along with the command (i.e. c:\jdk\bin\javac.exe)
Hope this helps
Hello,
Suppose you unzip the JDK in folder c:\jdk
Right click My Computer -> Select Properties -> Go to Advanced Tab (the rightmost one) -> Click Environment Variables... button
From System variables select PATH and click the Edit... button.
In Variable Value add at the end ';c:\jdk\bin' without the ''. Remember the ';'. If Variable Value is empty write 'c:\jdk\bin' (i.e. ommit the ';').
Click OK, OK, OK.
Go to Start -> Programs -> Accessories -> Command Prompt
Type java -version
It should show the jdk's version. If not then check the PATH again in case you have made a mistake.
Hope this helps
