Re: [Drjava-users] Stopping execution? Setting class path in DrJava

Has anyone replied to your other questions yet?  I apologize if not..

Yes-- just click the Reset button on the toolbar (or choose "Reset 
Interactions" from the Tools menu).  This will abort any code running in 
the Interactions Pane without forcing you to quit DrJava.

This is partially due to some quirky behavior in Sun's Swing library, 
but there might be ways to improve how DrJava handles this situation. 
Folks at Rice-- can you look into this?

Yes, as Corky mentioned, .jar files always need to be specified by name, 
while .class files are specified by the folder containing them.

Hope that helps, and sorry if this is redundant!
