Got this exception with Resin 2.0.1 as well as Jrun 3.0. Couldn't even get the CocoonServlet to start with Tomcat 4.0 because of a class cast exception on the CocoonServlet instance. org.xml.sax.SAXNotSupportedException: http://xml.org/sax/properties/lexical-handler at com.caucho.xml.AbstractParser.setProperty(AbstractParser.java:383) at org.apache.cocoon.components.parser.JaxpParser.parse(JaxpParser.java:75) at org.apache.cocoon.components.source.URLSource.stream(URLSource.java:321) at org.apache.cocoon.generation.FileGenerator.generate(FileGenerator.java:110) at org.apache.cocoon.components.pipeline.CachingEventPipeline.process I suspect it's a classpath problem and incompatibility between jarss.
