NotClassDefFoundError

Newbie & Debugging Questions
#1

I have JAVA_HOME=“C:\java;C:\java\bin”
and CLASSPATH=“C:\tomcat\lib;C:\java\lib”
when i do “java m.btr.core.Server” from directory where m(btr…) is placed i get:

C:\tomcat\webapps\ROOT>java m.btr.core.Server
Exception in thread “main” java.lang.NoClassDefFoundError: m/btr/core/Server
Caused by: java.lang.ClassNotFoundException: m.btr.core.Server

Could not find the main class: m.btr.core.Server. Program will exit.

The JAVA_HOME environment variable should only contain a single path like “c:\java”. If you want to start Tomcat (an interesting choice of game engine btw :slight_smile: ) you should use the provided startup/shutdown scripts in the c:\tomcat\bin folder.
