I'm a novice at programming and Java. So i really need the ABC of java! I've got jdk1.6.0_21 on my system and i use windows 7 OS. Trouble is i can't run any of the java programs that i write. I am able to compile but not run them. The programs are free of errors. All i get during runtime is a ClassNotFoundException. Would be glad if someone helps me with this! Thanks!
Show us the very first line of your source code; I bet your class is stored in a package while you don't know how packages are handled by the JVM.
kind regards,

Jos, Its a simple hello world program! Just seven lines! :( Do you think I should set my path variables?
This is what I get everytime I try to run a program on the console.
D:\Program Files (x86)\Java\jdk1.6.0_21\bin>java ex
Exception in thread "main" java.lang.NoClassDefFoundError: ex

Could not find the main class: ex. Program will exit.
Check if a file ex.class exists in the directory where you want to run it. (funny name "ex", I would've expected something like HelloWorld or similar).Quote:
