Anyone else who has got Tomcat 4 integrated with Apache 2 with mod_webapp and are using Struts out there? Does this sound familiar at all? Let me know (this was cross-posted on struts-user BTW):
I have successfully integrated Tomcat 4.0.3 and Apache 2.0.35 using the mod_webapp WARP module. Works perfectly for all my servlets/jsp webapps that are non-struts. As soon as I try to access my strutstest webapp, or if I try the struts-example webapp, I get problems (and, yes, I verified that these both work wonderfully when accessing them via http://localhost:8080/struts-example/index.jsp, etc.). For example, when I access http://localhost/struts-example/index.jsp, I get the page but with an error message at the top of the page: ERROR: User database not loaded -- check servlet container logs for error messages. and checking the logs as suggested, catalina.out supplies this: Starting service Tomcat-Apache Apache Tomcat/4.0.3 New org.apache.struts.webapp.example.User Set

org.apache.crimson.parser.Parser2.maybeElement(Parser2.java:1490) [snip] Strikes me that it may be a resource loading issue - is the webapp getting confused as to where to find /WEB-INF/struts-config.xml, etc.? Any one else using struts with Tomcat 4/Apache 2/mod_webapp and have it working fine for them? I can supply apache configs and tomcat configs as well if that will help.
