newbie exceptions question

[Nandan]

java -classpath WizTest_fat.jar bm.Tests.TestDiv tests/divtest4.xml
Exception in thread "main" java.lang.NoClassDefFoundError: bm/Tests/TestDiv

It might be worthwhile to catch this exception in the program and
offer a more informative error message.

am I correct in thinking the following?

That will not work. There is no way to catch that exception, as I understand
it. It isn't even a 'real' exception, as none of our code has been executed
at that point. It is really an error message from the java interpreter to
say it couldn't find the file. I may be wrong on this though, I will check.

Well, considering that the class hasn't been found I don't see how its
code can be executed.
No, probably it wouldn't work

So rather than call it an exception, is it more correct to say it's an
interpreter error message?

Thanks,

Probably not. It's a regular runtime exception that is thrown by the JVM
when a class is not found; not necessarily your main class. This means
that you can get it anywhere in your code.

The class bm.Tests.TestDiv can't be found. Make sure its in the jar
WizTest_fat.jar since that is the only place that is being searched...
