I'm now using the latest cvs code for logging, which seems to get me
past the earlier problem, but nonetheless, the problem is now in the
digester:
[java] [13:47:27.779-main][Digester][ERROR] - End event threw

It is now clear that there are classloading issues (after inspecting
digester code). I switched in a couple of places the use of the
Digester.getClassloader().loadClass() for Class.forName() and everything
works. Is this a bug? Is there an incompatibility with ANT? Problem
with 1.4.1?

Subject: Digester + Logging + Ant NullPointerException
I'm having yet another problem with logging. I figured someone else had
already uncovered this and discovered the issue (probably with my
environment).
Environment
Win XP Pro
Java 1.4.1_01
I'm also using Log4j 1.2.7.jar.
[java] org.apache.commons.logging.LogConfigurationException:
java.lang.NullPointerException
[java] at
org.apache.commons.logging.LogFactory.newFactory(LogFactory.java:558)
[java] at
org.apache.commons.logging.LogFactory.getFactory(LogFactory.java:355)
[java] at
org.apache.commons.logging.LogFactory.getLog(LogFactory.java:409)
[java] at
org.apache.commons.digester.Digester.<init>(Digester.java:281)
Any ideas?
