NoClassDefFoundError with RC

[keffe]

Hello!

I have installed Selenium RC and now tryning to use through CMD. I can
compile my file with javac but when I try to run my java file I always
get the this:

C:\>cd tests

C:\tests>javac Wiki.java

C:\tests>java Wiki
Exception in thread "main" java.lang.NoClassDefFoundError: Wiki
Caused by: java.lang.ClassNotFoundException: Wiki
at java.net.URLClassLoader$1.run(URLClassLoader.java:202)
at java.security.AccessController.doPrivileged(Native Method)
at java.net.URLClassLoader.findClass(URLClassLoader.java:190)
at java.lang.ClassLoader.loadClass(ClassLoader.java:307)
at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:
301)
at java.lang.ClassLoader.loadClass(ClassLoader.java:248)
Could not find the main class: Wiki. Program will exit.

What is wrong? I have googled som and I think it is something wrong
with my classpath, but I can´t understand what. I have tried to change
it according to some tutorials but nothing works. Is there any one who
can give me some suggestion of how I can fix this.

Well, this is a pure java class path issue and nothing to do with selenium.
I would suggest use an IDE like Eclipse to write any java code.
If you still want to run it from command line, then take care of few things.

First of all make sure the Wiki  class has a main method(public static void main(String args[]))

1. put the .class file to the proper package.
2. set the class path to the directory which contians the class files. and the
    dpendent jar files.
3. while running the main class use the fully qualified class name.
   like java com.selenium.Wiki

Ok. Thanks for your answer.

I have tried everything now but it won´t work. I have the correct
packages and my Path contains the directory to the class files. I give
up. Can you give me any links to some good tutorials how to work with
Selenium and Eclipse.

You don't mention exactly what you tried and whether the error was
always the same. It is odd that the missing class is the one you have
just compiled. Does this work for you? x.java:

---
public class x {
public static void main(String[] args) {
System.out.println("Hi world");
}
}
---
$ javac x.java
$ java x
Hi world

Is this the very first time you have tried to use java on this
machine? This is the most basic sort of test. It just works for me,
and it's my first java-on-windows install (XP). I would go to a java
group for further help. Maybe there's something wrong about your java
installation, which somehow allows javac to work but not java.
