Aren't classpaths just a pain!!!

I don't know how your directory structure is set up, but I have a VisAD
directory that has visad.jar in it along with the visad_examples.jar. I
unpacked the examples jar file and it created a visad\examples directory
under the VisAD  with the example source in there.  After I compiled the
java source to class files I have the .class files in the same directory.
In that directory, at the DOS prompt, I execute:

java -cp .;..\..\visad.jar River

And it runs.  You can also specify class path the in the environment
variable, CLASSPATH,  if you do not want to specify it in the command line.

It may be hard to read, so after the -cp  there is a period to specify the
current directory, then there is a semicolon, followed by two periods, a
backslash, two periods, another backslash and then the visad.jar file.

Hope this helps.

Luke
