DOCBOOK-APPS: Saxon and Catalog classes

I tried running saxon with Norman Walsh愀 catalog classes. But I run
into problems. When I execute the following command-line:

jan@magic:.../xml > java -cp /opt/catalog-1.0.1/catalog.jar:/opt/catalog-1.0.1/catalog-apps.jar:/opt/saxon-5.5.1/saxon.jar:/opt/saxon-5.5.1/. -Dxml.catalog.files=/etc/sgml/catalog com.icl.saxon.StyleSheet -o test2.html test2.xml /usr/local/share/xml/stylesheets/docbook-xsl-1.24/html/docbook.xsl

I get this result:

Exception in thread "main" java.lang.NoSuchMethodError: org.xml.sax.Attributes: method getQName(I)Ljava/lang/String; not found

Saxon is working without the catalog classes.
Any hints? What am I doing wrong?
