I'm using log4j 1.2.9 and JDK 1.5.0. Whenever getLogger() runs, I get the error below. It's probably something stupid but I'm stumped.

javax.xml.parsers.FactoryConfigurationError: Provider com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl could not be instantiated: java.lang.NullPointerException

Actually, I have some additional information on this. The problem only occurs when I run through an ant script. When I run using "java" then it works.

I have confirmed that ant is using JDK 1.5 by running in debug mode.

It seems to be some strange interaction between ant and log4j, probably having to do with a classpath or environment property however I can't figure out what it is.

I use the same classpath in ant and the java command line.
