Hi,

This looks like a typical classloading issue where you either have an older version of a library on the classpath or more likely duplicate JARs. Can you search your classpath for duplicate JARs (like Xalan in this case). The ExtendedContentHandler class also is contained in the JDK 6, so depending on what Java version you're using, the conflict might also be between the JDK and another library

The most likely scenario (but that's just a guess) is that you've packaged the xalan-2.7.1.jar within your application, but possibly any other of the listed JARs is sitting on the server's classpath. On some app server's it's possible to go into the management console and see from which JARs a particular class is loaded. It seems that there must be two JARs that contain org.apache.xml.serializer.ExtendedContentHandler

This issue is fixed by adding following property in carnot.properties and saxon.jar to the classpath

Carnot.Xml.TrAX.TransformerFactory = com.icl.saxon.TransformerFactoryImpl
