I tried with Admin privileges also still same but when I enter

echo %java_home%

or

echo %jre_home%

It is showing path corretly. Why isnt javac command working.

Any Help will be appreciated.

Answer 1

You don't have javac in your path. Setting the JAVA_HOME and/or JRE_HOME environment variables (which aren't needed any more, for the most part) does nothing to the PATH which the command shell uses to find executables.

Put the relevant JDK bin directory in your PATH environment variable instead - and unless you actually need JRE_HOME and JAVA_HOME for some reason, I'd get rid of them. If you do need them, get rid of the "bin" part - it should just be the root JRE directory, e.g.

c:\Program Files\Java\jdk1.7.0_45

Answer 2

You must restart cmd for new variables to be picked up. And java bin folder needs to be included in path. When you type javac it goes through all folders defined in path to find it.

Answer 3

Include the JRE/JDK path in System variables->PATH as well

After adding path varaibles,restart the cmd

Answer 4

That has nothing to do with Java environment variables.

When you type javac, or any other command, Windows will search the folders in the %PATH% environment variable to find an EXE file with that name.

You need to add your JDK directory to %PATH%.

You also need to restart cmd to pick up the changes.

Answer 5

Your path JAVA_HOME should be, for example

C:\Program Files\Java\jdk.1.7.0_45

And your Path variable should be

...;%JAVA_HOME%\bin

javac is in the bin folder which should be on your path.
