AbstractMethodError or xalan problems with tomcat

I get the following Exception (NoSuchMethodError, AbstractMethodError) when
i execute this line in a servlet:
Transformer transformer = tFactory.newTransformer(xslDomSource);

what i tried until now:
execute this line in a normal class and there everything works fine.
rename xalan.jar and xerces.jar to axalan.jar and axerces.jar so that
they are set first in the classpath. when i do this i got the Exception
java.lang.AbstractMethodError.

Does anybody know what i have to do so that xsl-transformation work with
servlets?

many thanks, Hans-Jürgen
