RE: tomcat 4.0 and struts problem
Verify if your error-page tags are defined before any taglib tag. Tomcat 4 not allows to declare taglib before error-page, even though tomcat 3 accepts it. -Message d'origine- De: Viet Kevin [SMTP:[EMAIL PROTECTED]] Date: jeudi 4 octobre 2001 16:52 À:[EMAIL PROTECTED] Objet:tomcat 4.0 and struts problem Hello all : I try to run struts with tomcat 4.0 and get this exception at the startup : java.lang.NullPointerException at org.apache.struts.digester.Digester.parse(Digester.java:755) at org.apache.struts.action.ActionServlet.initMapping(ActionServlet.java:1331) at org.apache.struts.action.ActionServlet.init(ActionServlet.java:465) at net.activia.cmanager.web.actions.CMActionServlet.init(Unknown Source) I find this is weird because all works well with tomcat 3.* Please help me ..., thx in advance
RE: tomcat 4.0 and struts problem
Title: RE: tomcat 4.0 and struts problem Hi, There was a similar problem discussed last week. My solution at the time was similar, and a bit dodgy :) I've just read the Tomcat 4 Class Loader HOWTO today and that explains the problems - as you've said its all to do with XML parsers. I think the suggestion from them is to move crimson and jaxp to $CATALINE_HOME/common/lib from jasper/lib, and not to put anything in your WEB-INF/lib directory. If you need Xerces 1.3+ instead, remove crimson jaxp from jasper/lib and put Xerces in common/lib (not WEB-INF/lib). I'm about to see if it fixes my struts mapping problems, and repost if not.

What I did was: 1 - Download Jboss ( www.jboss.org ) 2 - In the directory lib of jboss you can find crimson.jar and jaxp.jar files. 3 - Copy the two files to your $TOMCAT/webapps/yourapp/WEB-INF/lib 4 - Restart tomcat.
