JAVA -Setting system variables for Vista

[vertesi]

Hi all,

I am a newbee.

I am trying to follow the tutorial material, Hello World Tutorial, given by my professor, and I cannot seem to even get half way past the tutorial.


The issue I am having probably deals with my class path. I've read loads of commentary behind it, have tried to do it myself, and am unsuccessful.

I am posting becuase I need step by step instruction that are custom to my needs.

My system variables currently look like the following:

CLASSPATH: .;
PATH: C:\Program Files\Java\jdk1.6.0_03\bin
JAVA_HOME: C:\Program Files\Java\jdk1.6.0_01;

When I type "java -classpath . Hello" into the prompt, I recieve:
'java' is not recognized as an internal or external command , operable command or batch file.


Pls pls help. It would be much appreciated.

I posed my solution there, you can give it a try (it's for XP though).

"try after giving path to tools.jar n dt.jar in CLASSPATH"
Thanks for helping us beginners.

I have a feeling that only "PATH" in the user variable is nessisary and that CLASSPATH is actually red herring (kind of like "Area 51" being a diversion for the real alien laboratory down at "Area 52.5").

Just noticed you wrote:
"When I type "java -classpath . Hello" into the prompt, I recieve:

give this a try in a command prompt:
----
>javac hello.java
----

You have to compile before you can run it. Note that "javac" is not "java"; don't miss the "c". Also note, you just use "hello.java" and not "hello" with the "javac" command. Do not forget the ".java" extension. A file called "hello.class" should appear in the same directory as "hello.java".

then try:
----
>java hello
----
to actually run it

Let us know how that works for you.


Someone should make a video of: completely installing java JDK on a linux, a winXP and a win vista machine; typing out helloworld.java; running it through the command line; and upload those videos to youtube. Please.
