java -cp a.jar -jar b.jar => Works on Windows, not on Debian

[cyberco]

OK, I feel like a complete newbie posting this, but this has baffeled
me completely. I tried to execute the following:

java -cp a.jar -jar b.jar

Of course b.jar requires a.jar to run and both jars are in the same
directory. It worked on windows but not on Debian. I've checked a
million times that a.jar could be found by Debian (tried absolute
paths, relative paths, exported classpath env. variables, path env.
variables etc etc).

What could explain the difference between Windows and Debian? Are jars
treated differently on both platforms? Is it something in the manifest?

Well......found the answer here:

http://mindprod.com/jgloss/jar.html#CLASSPATH

Qoute:
"If you use -jar on the java.exe command line, java.exe will quietly
ignore the set environment classpath and any -classpath or -cp command
line options."

See the page for details how to solve this issue.

Thanks, Rudy!

what is the current directory in either case relative to where the
jars live?

I don't know why it works on one OS but not another, but you may as
