Q4E Version: 0.11.0.20100181900
Eclipse Version: 3.6
Java Version: 1.6
OS: OS X 10.6.5

Compiling a maven project whose packaging type is "war" throws an NPE (see
below) if IAM WTP support is installed but the container related bits of
WTP are not installed.

Comment #1 on issue 581 by mike.jam...@gmail.com: Unable to build WAR

archives without all of WTP installed
http://code.google.com/p/q4e/issues/detail?id=581

I'm getting the same exception. Yesterday (3/14/2011) I've downloaded the
latest release of Helios for J2EE, and updated/installed new software via
Eclipse update process for GWT SDK and Eclipse IAM (Maven). Then I
downloaded the archetypes for GWT and have been trying to get that to build
an empty war project for me. It creates the project, but at the tail end
of compiling, I get this same NPE error. I can reproduce this error from
scratch (from no IDE on my machien thru NPE error). I don't understand the
workaround mentioned above, as I've downloaded a version of Eclipse that
contains the WTP stack.

Eclipse:

Eclipse Java EE IDE for Web Developers.
Version: Helios Service Release 2
Build id: 20110218-0911

Top level error log message:

At this point, as best as I can tell, the IAM project is dead so you might
want to consider moving over to the sonatype plugin.

To fix this particular issue make go to the "Install New Software" menu and
make sure you have the WST Server Adapter installed and then ensure that
you have the IAM Web Tools Support plugin installed.

Please try with IAM 0.12 from
http://q4e.googlecode.com/svn/trunk/updatesite-dev/ and let us know if
still fails.

Hello, i'm having the same issue here with the updated version of IAM
(updated today, 2011/06/17).
Here is the error log :

Moreover, i have already installed WST Server Adapter v.
3.2.1.v201104191422-51EoAkF77g8HBSc and IAM Web Tools Support v.
0.12.0.201009031308,
so the solution proposed in comment #2 doesn't work for me.
