Assuming you're on Windows, you will need the swt DLL file to execute 
the program outside Eclipse.  Step 5a of
http://blog.redditech.com/professional/solution-to-problem-running-swt-app-from-jar/
mentions it (although they say you can pull it out of swt.jar, which is 
news to me -- my copy of swt.jar does not contain it).  The DLL file 
came with the SWT package, so I imagine it's on your system somewhere. 
This probably has nothing to do with the NoClassDefFoundError though.

Hmm.  How about java -cp "./program.jar;./swt.jar;." editor.editor?
