setting path variables

asked by MeghaB

you need to check if PATH environment variable points to the java executables directory.

Open command prompt

Run ‘set path’. This will print the current value of path environment variable. You can see the list of all the directories added. Check if Java sdk path is added or not. If it’s added you should be able to see something like below.
c:\>set path
Path=C:\Program Files (x86)\Windows Resource Kits\Tools\;C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\WINDOWS\System32\WindowsPowerShell\v1.0\;C:\Program Files (x86)\Quarantine\;C:\Program Files\Perforce;C:\Program Files\Microsoft Network Monitor 3\;c:\Program Files\Java\jdk1.7.0_17\bin
