It looks like the namespace has not been set for the unknownelement.
Can you provide a zip or tar file containing a build.xml, and java code
for the task to show the problem.

And then use it:

</filelister>
And I get a NullPointerException when using Ant 1.6.2, but
things work fine when using 1.6.0. I'm running the program
from Eclipse 3.0. The antTest.FileListerTask is in the
project's classpath.

Subject: Custom Tasks/Types in 1.6.2
To: [EMAIL PROTECTED]
I'm trying to run Ant from within Java. I've used code
similar to that in org.apache.tools.ant.Main and things
worked fine in 1.6.0, but then break in 1.6.2.
I think it has something to do with class-loading/namespace
stuff, but I can't find any good documentation or anyone
who's encountered a similar problem.
Can anyone point me to good documentation on class-loading
and namespace changes in 1.6.2?
