I you have the CLASSPATH environment variable set, and also use the -classpath option in the java command, does the -classpath option override the environment varibable paths, or are they both used.
Thanks for the help.

I don't know. You could try different settings and see which one works. Let us know what you learn.

I have tried, seems like a no-brainer to test, but my results have been inconsistent.
Sometimes it looks like it also uses to env variable and sometimes it doesn't.
That is why I wanted to know how it was supposed to work.
Thanks, sorry if it appeared as if I did not even give it a try.
Anyone know the rule?

From my experience (Windows), java -classpath will override the the system classpath always.

The command line option -classpath should always override the environment variables.
