@Eugene
Like I said, I installed a new eclipse (j2ee Version) with the newest
(non-developer) m2eclipse and the newest WTP (3.0.1). Still I get the
problem. Everytime I start eclipse I get the NullPointerException and
only the Deployment Descriptor is visible. By the way, I tried on two
computers.
If I then disable Dependency Management, everything is fine. If I
re-enable Dependency Management everything is still fine!!! If I restart
eclipse -> NullPointerException and only Deployment Descriptor visible.
Can anyone confirm this behaviour?
regards,
Jan

Jan,
The exception below is a WTP issue which supposed to be fixed in WTP
3.0.1. You should be able to update it from the Eclipse update site at
http://download.eclipse.org/webtools/updates

Update: I downloaded a new eclipse and installed all the newest (non

and restart eclipse I get the NullPointer again. Anyone?

I got it working for the moment but it is very unstable. My
procedure is to erase the eclipse files and use Update Project
Configuration and hit F5 for refresh. The results vary. Sometimes I
get only the source folders shown in eclipse, sometimes only the
Deployment Descriptor and sometimes the project like it should
appear but with a red cross at the project node. Unfortunately the
Problems view does not show a corresponding error. I could
"live"/work with that but if I restart eclipse I get the
NullPointerException (this time during JavaTooling Initialization)
and only the DeploymentDescriptor node is shown. By the way, unlike
in the tutorial I use Deployment Descriptor version 2.5 instead of
2.3. Did anyone got the example (Chapter 6) working (stable) with
tomcat under eclipse? If so, could you please give me the versions
of your installation?
Cheers Jan

Hi,
I am following the tutorials in the sonatype Maven book
http://www.sonatype.com/book (Thumbs up). Chapter 4 and 5 worked
perfect under eclipse but when I try the project setup in chapter
6, which is basically the same as chapters 4 and 5 but in a multi
module, eclipse starts to behave strangely. I am trying to run the
tutorial under tomcat (6.0.16) where I get a ClassNotFoundError for
the tutorial servlet classes (I cannot show it here because I
cannot reproduce the error due to the following issue). With jetty
from the console (like in the tutorial) it worked fine. After this,
the simple-webapp submodule project is broken. When I try Update
Project Configuration I get an error dialog showing the following
message:
An internal error occurred during: "Updating Maven Configuration".
java.lang.NullPointerException
And this is the stacktrace in the workspace log

Deleting the eclipse files and hitting Update Project Configuration
does not solve the problem. I am using Eclipse 3.4.0, WST 3.0.0 and
m2eclipse 0.9.6. Does anyone has a clue?
Cheers
