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
regards,
Eugene

Update: I downloaded a new eclipse and installed all the newest (non
developer versions) plugins and tried again. Once I get it working 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
Jan
