Can you re-phrase your question, it doesn't make a whole lot of sense. You'll also need to include the actual commands you are attempting.

Hello -
I'm having the following issue:
I am able to compile my java code with the javac command, but when I appempt to run it I get the java.lang.NoClassDefFoundError. I read other posts regarding this issue.
I have '.' in my classpath.
The directory that my class file is in is included in my classpath.
The file I'm trying to compile is a sample code for the JavaMail api. I've included the mail.jar file in my classpath and put it in my ext directory.
The actual error message I'm getting is:
C:j2sdk1.4.0JavaMailjavamail-1.2demo>java msgsend
Exception in thread "main" java.lang.NoClassDefFoundError: javax/mail/Message
Any other ideas?
Thanx!!

hi... i found this by searching for the error when I got it. compiling my 2nd java proggie :) anyway, to fix it: instead of typing "java [[programname.class]]" just type "java [[programname]]" it should then work. (substituding your actual program for [[programname]] of course....)

this is a solution, but you should do this anyway. There are other possibilities, one of which I am trying to figure out now...

Control panel => System => Advanced => Environment variables:
Find or create the "CLASS PATH" variable, enter all the paths of your .jar files. The hints:
1. Variable name: CLASS PATH. There should be a space between CLASS and PATH.
2. If you have more than one path, seperate them with ; and leave no space between them.
3. At the end of the last one, use a ; and then a . to finish the setting.
It will work.

Thanks that worked :P
I got to the program directory, and typed
# java [[program name without .class]]
and that worked for me (but I did set that CLASS PATH env. variable)
