Failed while installing Dynamic Web Module 2.5 [message #480304]

Eclipse IDE for Java Developers (Galileo)

The creation of a Dynamic Web Project in Galileo with WTP via the Dynamic
Web Project wizard elicits an error message:

Failed while installing Dynamic Web Module 2.5
Reason: [ditto]
Details: java.lang.NullPointerException

Project contents: Use default
Target runtime: Apache Tomcat v6.0 (works)
Dynamic web module version: 2.5
Configuration: Default Configuration for Apache Tomcat v6.0
[all defaults accepted]

The error occurs on clicking "Finish".

The project "xxx" is created; however, when trying to add a servlet to
"xxx" via the wizard, the project "xxx" is not available in the selector
labeled "Web project". The web project creation appears to have been a
failure.

Googling for the error message brings up some hits (for 2.5 and 2.4), but
no resolution. What could it be?

Being an Eclipe noob, what could I do to track this down?

Note that I'm *not* using the "Eclipse IDE for Java EE Developers", but
the simply the "Eclipse IDE for Java Developers" with additional
components such as WST, Subclipse, Java EE Developer Tools installed.

Michael,

Is this still a problem? If so, seeing the stack trace leading to the
NullPointerException would help.

Solved it, installing additional packages for j2ee develpment (not sure which package did the magic, installed almost all of them) ...

Anyway I think the cause is a dependency mismatch between WTP and J2EE plugins ...

Larry,

sorry I lost of track this thread I started. Reading Sebastiano's reply below, I installed all items in the collection "Web, XML, and Java EE Development" from the Galileo release site. That fixed it.

Where does Eclipse write stack traces? Didn't see any in the Eclipse installation directory. Do I have to do some configuration to make log files appear?

"...\workspace\.metadata\.log" contains all Eclipse errors.

Your stack trace is different from the one Sebastiano has posted, which is the same I've observed in my Eclipse log file once I discovered it.

So I don't think you're experiencing the same issue.

If you're still sure it's the same issue, you can try installing all items in the collection "Web, XML, and Java EE Development" from the Galileo release site. That fixed it for me and, apparently, for Sebastiano as well.

I just reinstalled the Java EE ones and that seems to have fixed it. It's
the 3rd time I tried that though so I guess 3rd time is the charm.
Strange.

It appears that you need to install one or all of the following:

JST Server UI
JST Web UI

It's probably a good idea to also install the following:

JST Server Adapters
WST Server Adapters

Hope this helps.

Thanks for everyone's input, you got me started in the right direction. I had the same symptom, similar solution, but my stacktrace is a bit different.
