Java and PATH variable on Windows XP

Thread view:

I have recently installed Java 1.4.2 on Windows XP.

I can compile and execute programs without problems but I am curious as to
how, when I open a CMD window, java, javac etc are in my PATH when I have
not set up my PATH variable?

Here's an example:

C:\Documents and Settings\user>echo %PATH%
C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem

C:\Documents and Settings\user>java -version
java version "1.4.2_03"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_03-b02)
Java HotSpot(TM) Client VM (build 1.4.2_03-b02, mixed mode)

I think if my memory serves me correctly I installed Java as part of a
Netbeans download - not sure this makes a difference.

Just curious.

Thanks.

Are you sure that javac works? java.exe will work because it gets put in
c:\windows\system32.

I can invoke java with no prefix/path,
but javac, javadoc ets. all require it.

I suspect the OP's IDE has set-up the
path for the others.

Look in:
Control Panel
System
Advanced
Environment Variables

The IDE/package will put them there and/or you can edit them yourself.

That's bad. Sun recommends that
you should set cp attributes on a
project by project basis.
