Can you please explain this text from the wiki:

gwt.noserver tells Development Mode that the application is already deployed on JBoss AS (don't use embedded Jetty instance to serve application content) 

Or this:

Q: Client-side logs are not persisted on Engine, e.g. $JBOSS_HOME/standalone/log/engine/engine-ui.log.
A: Currently, client-side logs are enabled only when debugging the application via Development Mode.

What listens on port 8700?

Thanks!
