Hi List, this is a simple issue i stumbled upon today. I just wanted to add a Servlet Filter to my Web Application today, but it did not validate the web.xml, but i was sure i got it right.
After all, i found the error to be the wrong DTD included in the web.xml-File of the Turbine TDK 2.3_01 i use. Maybe this saves someone around half an hour of questioning yourself what you did wrong. https://list.unm.edu/cgi-bin/wa?A2=ind0310&L=jasig-portal&F=&S=&P=25153 The Exception was: 2004-06-21 14:01:19,242 ERROR [main] (Digester.java:1439) - Parse Error at line 50 column 11: The content of element type "web-app" must match "(icon?,display-name?,description?,distributable?,context-param*,servlet*,servlet-mapping*,session-config?,mime-mapping*,welcome-file-list?,error-page*,taglib*,resource-ref*,security-constraint*,login-config?,security-role*,env-entry*,ejb-ref*)". org.xml.sax.SAXParseException: The content of element type "web-app" must match "(icon?,display-name?,description?,distributable?,context-param*,servlet*,servlet-mapping*,session-config?,mime-mapping*,welcome-file-list?,error-page*,taglib*,resource-ref*,security-constraint*,login-config?,security-role*,env-entry*,ejb-ref*)". at org.apache.xerces.util.ErrorHandlerWrapper.createSAXParseException(Unknown Source) at org.apache.xerces.util.ErrorHandlerWrapper.error(Unknown Source) at org.apache.xerces.impl.XMLErrorReporter.reportError(Unknown Source) at org.apache.xerces.impl.XMLErrorReporter.reportError(Unknown Source) The Solution was to replace the 2.2 in the XML DTD Part of the web.xml-File with 2.3: <?xml version="1.0" encoding="ISO-8859-1"?> <!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/j2ee/dtds/web-app_2.3.dtd";> And cheeers, the filter works. Have a nice day, martin
