I'm trying to write a really simple Java app that uses the Xerces XML

When I run my Ant task through Eclipse, I get:
BUILD FAILED: java.lang.NoSuchMethodError:
org.apache.xerces.xni.parser.XMLComponent.getFeatureDefault( Ljava/lang/String;)Ljava/lang/Boolean;
The Xerces JAR files are all set up in the Ant task CLASSPATH settings.
Without these entries, I get a class not found error.
I can run ant from the command line fine and Eclipse can compile my
source directly as well. Any ideas why this error would occur? I assume
the mentioned method is in one of the JAR files. Would tracking that
method down help?

I'm using Eclipse 2.1.2. I'm willing to try the latest milestone if it
may help but I assume 2.1.2 is a better choice since I need stability
more than new features.

Hi Roger
Have you checked that method actually exists on your xerces jar? Maybe the
version you used to develop is not the same as the one you're trying to
build with.

Very informative. Thanks to both of you. I will try out M6 when it comes
out.
I really don't care which version of Xerces I use (don't care if I have
to use another XML library although it would preferably be DOM-based),
but without downloading the Xerces JARs and adding them to my classpath,
my import statements failed.
I'm sure you are right, that it is confused between the Eclipse Xerces
and the version I downloaded. The straight command line build works
perfectly (which is what I will use in the meantime).
Thanks again, you guys are very helpful!
