Executable jar file

[sc_wizard29]

Hi everyone,

I have an executable jar file that lies in c:\lib (yes, I'm on a
windows box)... and I want to execute it from c:\

This jar file contains the following MANIFEST.MF file :

Manifest-Version: 1.0
Created-By: 1.4.2_08 (Sun Microsystems Inc.)
Main-Class: sub1.HelloWorld1

I've tried 3 different ways to execute the jar file :

C:\>java -classpath ".\lib\sub1_exec.jar" sub1.HelloWorld1
HelloWorld1.main() : hello world
C:\jar>java -jar .\lib\sub1_exec.jar
HelloWorld1.main() : hello world
C:\jar>java -classpath ".\lib\sub1_exec.jar" -jar sub1_exec.jar
Unable to access jarfile sub1_exec.jar

Can anyone explain me why the last method doesn't work ? (and what can
I do if I don't want to make it work ?)

Thanks for helping... this stuff is driving me crazy ;-)

Because the -classpath parameter is ignored when you specify -jar

See the description of the -jar parameter at
http://java.sun.com/javase/6/docs/technotes/tools/windows/java.html

"When you use this option, the JAR file is the source of all user
classes, and other user class path settings are ignored"

That was a fast answer... thank you very much !!!

Why did you put your question on the end
of this thread that has nothing to do
with books?

It makes more sense to start a new thread
under the subject 'Book recommendations'.
