I have seen too many people, including myself, falling for
classpath issues while developing in Java. So here's something
from my experience to help newbies out:
1. Always try to find a Win2K/XP or Linux for your development
work. The DOS prompt of Win98 is simply insufficient for serious
Java development.
2. Grow yourself some good habit. Before just shoveling a jar
onto a classpath, always ask yourself, "does it belong here?"
I have seen a lot of developers hacking their classpath just

Agree. It Win98 sucks. I use NT though. :)
I add one thing: make sure you have only *one* copy of everything
in your classpath. You don't want to end up with multiple copies
which could give you headache on the LinkageError or version conflicts.
In DOS mode, use setlocal ... endlocal to make sure that your classpath
settings are strictly local. Also you could use -classpath option

Use an IDE you will solve all these problems.

Actually not. One thing not so good about IDE is that it does
too many things for you, one of them being forming the classpath
for you automatically. For example, NetBeans (at least as of 3.3)
forms both compile and run-time classpaths from all the filesystems
you mount, regardless if it's src, or lib, or whatever other folder
you just mounted for convenience. On top of that, it has its own
running classpath included automatically, too.
Fortunately, new generations of IDE's have been adding
