That doc is somewhat incorrect, in particular this statement: "In previous versions of Tomcat 5, you could simply replace the XML parser in the $CATALINA_HOME/common/lib directory to change the parser used by all web applications. However, this technique will not be effective when you are running on J2SE 1.4, because the usual class loader delegation process will always choose the implementation inside the JDK in preference to this one." It ignores the ability to override the JRE/JDK implementation by using the appropriate system property or the JAR Service Provider mechanism. I suspect the latter is why placing the oddly named a_xercesImpl.jar in common/lib allows things to "work". Setting -Djaxp.debug=true might generate some light on the issue. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
