Isn't SAXBuilder part of JDOM?

You're right. My brain's elsewhere. I meant Builder.

Elliotte,

I fixed temporarily this problem by miving the Xerces files

xercesImpl.jar
xercesSamples.jar
xml-apis.jar
xmlParserAPIs.jar

from here:
C:\Program Files\Apache Group\Tomcat 4.1\webapps\wurfl\WEB-INF\lib

to here:

C:\Program Files\Apache Group\Tomcat 4.1\common\lib

Any idea why this does the trick?

It probably changes which ClassLoader loads those files. ClassLoader issues are a real pain. It's possible to have two separate but equal versions of the same class loaded at the same time, which are not compatible with each other even though they are identical.

I'm pleased to announce that I've posted build 1.0d11 of XOM in the ususal location:

http://cafeconleche.org/XOM/

The new feature in this release is an ANT build file. This should make it much easier to compile XOM from source. ANT is not included though. You'll have to download and install it separately.

Before I make a broader announcement, I'd appreciate it if you could download this and test out the build file. I've only used it with ANT 1.5b3 and Java 1.4.2b1 on Linux. If anyone has problems on other versions please let me know. I'm especially curious how this fares in Java 1.2 and 1.3 and on Windows.

There are no API-level changes in this release. All code that ran before should still run. This release does fix all three outstanding bugs
reported by users:

* Worked around a bug in later versions of Xerces that don't
like null entityresolvers
* Allow base URIs to contain % escapes
* Fixed a bug that throws NullPointerException when serializing
documents without a base URI with preserveBaseURI set

I've expanded the unit tests to catch these and related bugs. The unit tests all pass, assuming you use a non-buggy SAX2 parser. However, if you run the JUnit GUI from the ANT build file, some confusing class loader issues cause the more-buggy Crimson to be loaded instead of the less-buggy Xerces. This breaks four unit tests. Everything should pass if you run the tests directly instead of from ANT. (That is, type "java -Xmx96m junit.swingui.TestRunner nu.xom.tests.XOMTests" instead of "ant testui".) If anyone can explain to me how I might fix this, I'd appreciate it.
