I have a small Java application with a few classes. I used Eclipse and
created a new "project" and put the classes in the default package.

Then I decided a couple of the classes would be useful in other of my
applications so I created a new "project" and created a package
"org.foo.bar.utils". I copied the reusable classes here and deleted them
from the original project.

I tried various settings in "Project" "Properties" but cant get the
application to compile and run now.

In "Project", "Properties", "Libraries" I used the "Add Class Folder" and
ticked the box for "org.foo.bar.utils". The app comiles now but at runtime
I get "NoClassDefFoundError".

I've tried a few other things such as adding "org.foo.bar.utils" as a
library and inserting an import statement but am not getting any joy.

Is there an idiots guide to this?

Put your shared classes in a project. Let's say this project is called
"SharedStuff". Let's say you want your project "ProjectX" to be able to
access the class in SharedStuff. Right click on ProjectX and choose
properties.

Click on the "Java Build Path" in the tree on the left. Choose the
"Projects" tab. Click the "Add" button. Put a check mark next to
"SharedStuff". Click "OK". Click "OK".
