running .class from cmd

[rolfarj]

Hello. I am trying to run .java-files from cmd. First i type: "javac filename.java" to make it into a .class-file. This works fine, but when i try to run the .class file typing: "java filename" i get an error message:

Exeption in thread "main" java.lang.NoClassDefFoundError: filename

Do you know what I am doing wrong. Maybe i have need to configure java in some way?

This is a classpath problem:
try using
java -cp . filetitle
alternatively set your classpath at command line thus:
set classpath=.
then you can use java filetitle
