Re: "Web application descriptor must be a valid web.xml" build error

[Glen Mazza <gl...@gmail.com>]

No--same error even if I do that, even if I delete the file.  Maybe it's
requiring a 2.4 web.xml (I'm relying on a tutorial sample--I can upgrade
it.)  I'll look into entering a (Maven, apparently) JIRA for a better error
message--I need to know whether it can't find the web.xml, or it can but
there's something wrong with the file.  The troubleshooting you do in each
case is very different.

Thanks,
Glen
