Java: NoClassDefFoundError. WTf?

seamus

OK, in an attempt to solve this problem, I'm trying to move the project to a linux box.

Compiles fine, all the files in the project are in the same package (and correct directory), but when I go to run the testbench, I get

Exception in thread "main" java.lang.NoClassDefFoundError: test/class

And I'm stumped. The test file is included as part of the package, and only has a main method. Nothing more. Have no idea what's going on.

[Sorry for spamming the programming board

Without more information it's a bit difficult to tell, but it's almost certainly a problem with the way you've defined your package and the location the class files get compiled into..

it's also possible (seeing as you mention that you moved platforms) that you may have compiled with for example, Javac 1.4 but ran with Java 1.3 and used some new class only available in Java 1.4.

It's grand, I got it sorted. You can't call a program inside a package in the normal (java test.class) way.

You have to call the entire path, ie

java -classpath ./whereispackage/ com.mypackage.test

Because deleting is bad, and someone else may have the same problem.

Actually that's a common trip up problem, along with defining main() as a method rather then a main() method.

it is a good idea also to use java.FileSeperator for cross platform stuff.

manys the month that has been wasted,

So did it work properly on the linux box after moving it?
