Hi, When we started to use Jena, we had a similar problem: under Tomcat everything was fine but under Resin we got Xerces related exception. We solve it by adding the following configuration:
<web-app xmlns="http://caucho.com/ns/resin";> <!-- xml --> <system-property javax.xml.parsers.DocumentBuilderFactory= "com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl"/> <system-property javax.xml.parsers.SAXParserFactory= "com.sun.org.apache.xerces.internal.jaxp.SAXParserFactoryImpl"/> </web-app> It may help you too?
