It won't compile !!

[Ward Loockx]

Hello ,

I'm @ the beginning of programmers school and in school we compile our
programs with simple "javac filename" in dos. Now I wanted to compile
a program @ my place but it always says this :

C:\Documents and Settings\Ward Loockx>javac
javac wordt niet herkend als een interne
of externe opdracht, programma of batchbestand.

in english it means : javac isn't recognized as a internal or external
task , program or batch...

Now everything is in my dir, like we have in school ..

What can be the problem ?

You'll get the same response if you type "wibble", "wobble", or anything
else that doesn't exist on your system. Try installing the Java SDK
http://java.sun.com and then you'll have a working javac command, and more.

You haven't correctly installed java on your machine,

See
http://java.sun.com/j2se/1.4.2/install.html
or
http://java.sun.com/j2se/1.5.0/install.html

dependign on the version you have/will install.

I'm @ ..

Please do not use silly abbreviations such as 'u', or '@'.

..the beginning of programmers school ..

A better group for beginners is described here..

..and in school we compile our
programs with simple "javac filename" in dos.

Again, for the sake of clarity, DOS.

.. Now I wanted to compile
a program @ my place but it always says this :

C:\Documents and Settings\Ward Loockx>javac
javac wordt niet herkend als een interne
of externe opdracht, programma of batchbestand.

in english it means : javac isn't recognized as a internal or external
task , program or batch...

You need to set the path to the 'javac' command..
On my system it is..
C:\Program Files\Java\j2sdk1.5.0\bin\"

So I put a file at C:\javainit.bat that reads..

if not defined JAVA_HOME set JAVA_HOME="C:\Program
Files\Java\j2sdk1.5.0\bin\\"

...all one line.

Then create a file such as xCompile.bat in the directory
with the Java source files.

call C:\javainit.bat
%JAVA_HOME%javac *.java

[ Note that I have set the follow-ups to the help group referred
to above, if you need to make replies, follow them there.. ]

If you've installed the JDK, you haven't added the JDK bin directory to your
PATH. The instructions are in the install.html file that is available where
you downloaded the JDK.
