Jaxb java.lang.NoSuchMethodError com.sun.xml.bind.util.AttributesImpl.getIndexFast

[Anna]

I am trying to use JAXB to unmarshall and marshall xml documents. I've
written a simple test class with a main method that I'm executing via
eclipse which takes an xml file from my c drive and unmarshalls the
data. Everything works great.

I'm now taking the same code and implementing it within an application
I'm developing. The application server I'm using is ATG.

I have added the following classes from the java web services developer
pack to my classpath

JAXB jar files -- jaxb-api.jar, jaxb-xjc.jar, jaxb-impl.jar,
jaxb-libs.jar
JAXP jar files -- jaxp-api.jar, sax.jar, dom.jar, xercesImpl.jar,
xalan.jar,
jwsdp-1.5/jwsdp-shared/lib -- jax-qname.jar, namespace.jar, xsdlib.jar,
relaxngDatatype.jar

When running my application I keep getting the following error.
java.lang.NoSuchMethodError:
com.sun.xml.bind.util.AttributesImpl.getIndexFast(Ljava/lang/String;Ljava/lang/String

I know the class AttributesImpl exists within jaxb-impl.jar. i also
know the method getIndexFast exists because I can call it within a test
java class. I've also modified my classpath to make sure that
jaxb-impl.jar is the first jar in the classpath. I did this to make
sure that if the class exists anywhere else its called from this jar.

I hav eno idea why i'm getting this error. Any thoughts from anyone
would be greatly appreciated. I've pasted the complete stack trace
below.
