I've already copied swt.jar to the same directory as program.jar and I
don't know if I need any dll to execute my program. I've added
org.eclipse.swt to my build path, added swt.jar to libraries, and in

org.eclipse.swt) but still don't work.

Still give me the same error.

Yes.
Manifest-Version: 1.0
Main-Class: editor.editor
Classpath: swt.jar

swt-3.2.2-gtk-linux-x86.zip and import it to eclipse. Then I create a
new java project, adding org.eclipse.swt to build path
