No. Our code calls list-applications. But when something like this
breaks, it's faster to glance at domain.xml than to fire up the
debugging or restart NB w/ high detail logging.
Anyway, it looks like perhaps list-applications is broken by this as well.
A web app on TP2 + metro is being returned by list-applications as
"MyWebApp <>" instead of the expected "MyWebApp <web>". The engine list
of such an application is empty. It is supposed to contain "web", since
this is a web app. Please note that this web app DOES NOT use web
service in any way. Merely, the server in question has the metro bundle
downloaded.
I filed
https://glassfish.dev.java.net/issues/show_bug.cgi?id=5197
I'm a little worried about the fact that an arbitrary container provider
(metro in this instance, but it could be anything installed on the
server) can effectively disable the visibility of the web container (and
thus presumably any other container) in such a manner.
I do not see a way to enable the NetBeans tooling to defend against this
behavior.
