Hello,

I'm very new to Java/Eclipse.
I've installed the Eclipse Helios version on my PC/Windows.
I've created a very basic project HelloWorld that works fine.

I'm trying to create a JUnit test using the wizard and when I launch the test, I get the following error. (I tried JUnit 3 and 4, same result):

java.lang.NoClassDefFoundError: org/eclipse/jdt/internal/junit/runner/RemoteTestRunner
Caused by: java.lang.ClassNotFoundException: org.eclipse.jdt.internal.junit.runner.RemoteTestRunner
at java.net.URLClassLoader$1.run(Unknown Source)
at java.security.AccessController.doPrivileged(Native Method)
at java.net.URLClassLoader.findClass(Unknown Source)
at java.lang.ClassLoader.loadClass(Unknown Source)
at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source)
at java.lang.ClassLoader.loadClass(Unknown Source)
Exception in thread "main"

I don't know how to tackle this error? Any help to correct this problem would be appreciated.

Thank you by advance

1. Right-click on your project and choose Build Path -> Configure Build
Path.

2. Click on the Libraries tab.

3. Click Add Library.

4. Click JUnit, then choose either JUnit 3 or 4 depending on which you
want to use (if you're going to use Java 5 or 1.6, I'd suggest JUnit 4).

5. Right-click the JUnit test you wanted to run and choose Run As ->
JUnit Test.

You shouldn't be missing this symbol now, I think.

The correct JUnit lib was automatically included by the wizard.
I tried with both version of JUnit (the correct lib was proposed) but the error remained..

You need to check the launch configuration.
