This has been spun off from JBIDE-6754.

"We will also spin off a second JIRA to provide a read only text box somewhere on the wizard page that attempts to assemble what the path will look like. There are issues with that, since we would have to look into web.xml (if exists) and search for classes implementing Application interface and look which method is going to return newly created class...

However, we both agreed that that functionality won't be done for this release, though it would be very useful to show the rest of the wizard page details in context."
