javac not recognized as an internal or external command

[Norm]

That makes it hard.

I am using version jdk1.6.0_21, so I appended the following exactly to the end of my PATH field.

;C:\Program Files\Java\jdk1.6.0_21%JAVA_HOME%\bin

I ran a couple of exe's from the command line, and did not receive any errors.

I also ran from the command line:

java -version

And I received back the correct data:
java version "1.6.0_21"
Java(TM) SE Runtime Environment (build 1.6.0_21-b07)
Java HotSpot(TM) Client VM (build 17.0-b17, mixed mode, sharing)

What is the value of JAVA_HOME? It seems to me that you are using things two times; your path variable should contain C:\Program Files\Java\jdk1.6.0_21\bin or just %JAVA_HOME%\bin where JAVA_HOME is set to the correct value.

ooOOHHHhhh - thankyou JosAH - I wasn't sure about it, but was trying different things because I couldn't get anyone to tell me definitively which is better.

What do you recommend?

If I were to use %JAVA_HOME% , where would I set the correct value - is there a global place to set it?

I am having trouble running the compiler on a program from the command line - I have saved the program as *.java, and attempted to run:

javac *.java , but it can't find the program. I did save the code in the Program Files\Java folder, but it still does not find it. Can you suggest what I might be missing?

You set it in the same dialog box as where you set your path variable. Both are environment variables; for now I'd forget about JAVA_HOME and set the PATH variable to where your javac.exe file is stored.

Thanks JosAH , I actually figured it out after I posted the question. I prefer to use JAVA_HOME (I added the variable to the list so that I could use it). Thanks! :)

hi all,

I installed jdk1.6.0_21 version and if I try to compile a simple Hello.java file, it throws an error saying "javac is not recognised as internal or external command". I have set my path as E:\Program files\java\jdk1.6.0_21\bin; Should it be set as both user & system variables??

Whats the mistake here?? plzzz help.

@DIVYAG :::problem with javac

create and set user variable JAVA_HOME = "E:\Progra~1\java\jdk1.6.0_21\"
instead of "E:\Program files\java\jdk1.6.0_21\bin"

also edit system variable PATH=;E:\Progra~1\java\jdk1.6.0_21\lib;

cheers

If you have your own question, you'd be best to ask it in it's own thread and give more details such as how you are trying to call things and what error messages you may be getting. Locking this older thread.
