You can fix the ClassNotFoundException by adding the directory containing your packages (and then your .class files) into your classpath. It's important to make it work first outside of your favorite IDE in order to exclude Java itself from the possible root causes.

Then, when it works in command line, we can suspect that Eclipse doesn't show all directories included in its classpath and maybe it really has a problem with escaping spaces in paths.

In which directory is your Eclipse project? Please provide the absolute path.
