The listener was not written by me, so i don't know why this way was chosen. I changed the implementation, now it checks if jaxp is yet configured. Thanx for your pointers concerning this!
Perhaps interesting for you:
Write a servlet context listener with the following implementation
> public void contextInitialized( ServletContextEvent sce ) {
> System.setProperty( "javax.xml.parsers.DocumentBuilderFactory",
> "org.apache.xerces.jaxp.DocumentBuilderFactoryImpl" );

this prevents tomcat 5.5.4 from starting successfully,
in tomcat 5.5.3 it has no impact.
