Re: [math] Help, how to compile? Thanks a huge
You need to use -classpath when you run java as well as when you run javac.
Also, you need to include [math] on your subject line when posting about
that module to this list.

You need to put both the commons math jar *and* the directory which
contains
the Test.class file in the classpath. You can add several elements in
the classpath by
separating them with ':' (for Unix) or ';' (for Windows). So you will
end up with
someting similar to:
-classpath
C:\some\path\to\commons-math3-3.1.jar;C:\another\path\to\directory

We do not hold this kind of tutorials at the Apache Commons project.
I'll suggest
you to look for introductory tutorial to run any java programs from the
command
line. The problems you encounter are not specific to Apache Commons
Math, they
correspond to general Java usage.

[math] Help, how to compile? Thanks a huge
Posted by George Xu <to...@gmail.com>.
Hi,
I compiled with -CLASSPATH and it passed and generated the .class file.
(>dir *.class shows)
But when I ran with
>java -CLASSPATH commons-math3-3.1.jar(full directory path) Test,
it complains "Error: Could not find or load main class Test".
BTW, is there introductionary PDF doc for questions like this?
