tomcat run works, but debug fails to find classes

Found the problem: the dreaded "space in the classpath". Renamed
"chapter 3" to "chapter3" and all works :->

I can run the app from idea via run and all works well. But when
debugging the first time my app needs to load a struts action, the class
cannot be found.

Is this a common problem (I can't seem find anything like in the forum
or tracker)? Or do I need to flesh out the details?

(BTW, I running the chapter 3 sample banking app from theserverside
struts book preview)

thanks!
