Mauro,
There have been some sporadic reports of this kind of problem, but
nothing that has been traced to something specific. Feel free to open a
bug on ServerTools where we can pursue the cause. I would be curious
what isn't published, jars, class files, static content, all of the
above? Also, does forcing a "full" publish with "Clean..." fix the
publishing problem?
Cheers,
Larry

I'll try a Clean on the server (rather than on the project) next time.
I'll let you know.
From what I can remember, META-INF and WEB-INF folders were created,
along with web.xml e MANIFEST.MF, but static resources were not
published. If I remember well, classes were not published, while I'm
pretty sure that just some of the JARS in WEB-INF/lib were.
In the log, a suspicious entry might be:

I'll try to be more precise next time it happens. Since I'm working on a
test project based on open source code, I may even provide you the
project to test. Would a ZIP containing the project help you to
investigate, alghouth the bug happens only sometimes?
Mauro.

The NPE looks to be thread safety issue and it's a bug that "null" is
printed for the "Could not replace" message. I'll see what can be done
to improve these in WTP 3.2.2 and 3.3. Unfortunately, these don't give
much of a clue as to what exactly is going wrong or how to work around
it. If you are interested, it is not difficult to create a patched
plug-in. We try some simple changes to see if it helps your situation.
Cheers,
Larry
