Hey anyone

A have a problem with Junit. I have installed it and added it to my
CLASSPATH like this:
C:\junit\; C:\junit\junit-4.1.jar

But when I try to run the test it fail like this:
C:\>java org.junit.runner.JUnitCore org.junit.tests.AllTests
Exception in thread "main" java.lang.NoClassDefFoundError:
org/junit/runner/JUnitCore

I'm running Windows XP.

I have restartet Windows after I have changed the CLASSPATH.

Any help??

Kind regards
Jimmi Wolff

It helped, tahanks. But now I get a new problem:

C:\> java org.junit.runner.JUnitCore org.junit.tests.AllTests
Exception in thread "main" java.lang.UnsupportedClassVersionError:
org/junit/run
ner/JUnitCore (Unsupported major.minor version 49.0)

Can anyone fix that?

Your JDK and JRE versions don't match or at least JUnit was compiled
with a newer compiler. Use the same releases, or try to compile
everything from scratch with with the -target option (and -source and
-bootclasspath) for your older JRE. The later might fail if your source
code uses newer Java features and APIs.

That means that you are attempting to load a class, apparently
org.junit.runner.JUnitCore, which has been compiled by a 1.5 compiler and is
intended to run on a 1.5 JVM, into an older JVM. If you can't, or don't want
to, update your platform, and can't find a version of JUnit compiled for that
platform (presumably 1.4 or 1.3), then you'll have to rebuild JUnit from source
yourself.

Your version of JUnit was compiled with JDK 1.5.0, and you are trying to run
it with an older version of the JRE.

Solutions:

1. upgrade to JDK 1.5.0 on your development platform

or

2. download an older version of JUnit that does not require Java 1.5
features. JUnit 3.8.x versions will run under JDK/JRE 1.4.
