Stanimir, You are correct, the error occurs when I try to build the application (by implement I meant that I was trying to introduce the new Xerces parser to our application, sorry for the confusion).
Michael, I used the deprecated build process to create a single xerces.jar file from the 2.9 components (per the instructions on the apache site). It was our understanding that this should be a straight replacement for the older 1.4.x xerces parser, but we are getting the errors mentioned in my previous post during the build of our application. I even tried including the five different jar files (including all five of them in my classpath via my IDE (Eclipse)), but the error persisted. steve The contents of this e-mail are intended for the named addressee only.
