Answer 1

I had a similar problem running a HelloWorld program I had written with a text editor on Mac OS X. It ran fine on a remote Linux box, but running it from home directory I got the dreaded NoClassDefFoundError.

java -cp . HelloWorld

or, without the classpath qualifier, after adding the current directory to my bash CLASSPATH for the current session:

export CLASSPATH=.
