Hi, Morten -- Sorry it's taken me so long to respond. The short answer is that it is most likely that your Translate class is not on your classpath. I tried your example and, after changing the "replace" call in the stylesheet to "replace2", it worked just fine. Be sure that you know what your classpath is. Are you executing this from the command line or from a servlet or EJB or something like that?
If you have any questions regarding this, look at Shane's org.apache.xalan.xslt.EnvironmentCheck class and follow the directions in the javadoc there. You didn't include a stack trace so I can't be sure but if you see the class org.apache.xalan.extensions.ExtensionHandlerJavaPackage near the top of the trace, this indicates that java couldn't find your dk.bording.axt.tc.xsl.Translate class and is instead trying to treat it as a package.
