java.lang.NoClassDefFoundError: com/google/gwt/user/client/rpc/RemoteService

[Jonas]

Hi!
I have tried to deploy my webapp into Tomcat. It works out fine when I
run it inside the normal development shell. But when I try to run it
in Tomcat I get a NoClassDefFoundError. I think this has something to
do with to project settings. What should be in the servers WEB-INF-
folder as of GWT? This server is a Tomcat 5.5.

Kind regards
Jonas

I think I sorted it out. Eclipse didn't copy gwt-servlet.jar into
Tomcat. This was perhaps because it wasn't in WEB-INF folder whithin
the GWT-project.
