I get a similar error message when I try and run a JAR file without the -jar flag. Are you sure you have set up your OS (windows?) properly?

>java Jmol.jar
Exception in thread "main" java.lang.NoClassDefFoundError: Jmol/jar
Caused by: java.lang.ClassNotFoundException: Jmol.jar
        at java.net.URLClassLoader$1.run(Unknown Source)

Could not find the main class: Jmol.jar.  Program will exit.

yes but it need to go bin folder for running i.e

c:\program files\java\jdk1.6.0_22\bin>java -jar c:\CRDO_Sys.jar

You need to add the java bin directory to PATH. See 'Environment Variables' in Windows help
