Hi,
When calling OMElement.serialize(...), an exception is thrown with the following stack trace:
java.lang.NullPointerException

What am I missing here?

Excellent. I downloaded the latest JAVA update and the problem is gone.
Thanks a lot!

Mats,
This is actually a bug in Sun's StAX implementation [1].
You have several options to work around this:
1. If you are using the StAX implementation that comes with Java 1.6,
try to upgrade to a more recent version.
2. Use Woodstox [2]: this is the recommended StAX implementation for
Axiom. If you are currently using the StAX implementation form the
JRE, just add the Woodstox JARs to the classpath. If you have SJSXP in
your classpath, replace it by Woodstox.
3. Try with a snapshot version of Axiom [3]. In the current trunk, we
have implemented a feature that deals with broken parsers. In
particular, Axiom now has a workaround for this particular issue in
SJSXP.

Well, it was the first time I tried this code. No heavy load. I would say it's predictable.
Any idea? I did find one other similar report on the web, but no answer.

Mats,
Is this exception predictable or does it occur randomly under heavy load?
