I followed the example from this page to do a simple setup.
http://struts.apache.org/2.x/docs/simple-setup.html I copied the jars listed into my lib folder, I ccopy and pasted the web.xml from this page and put it in my WEB-INF folder and I copied and pasted the struts.xml file into my classes folder. I removed the '...' from between the package tags. The application seems to be having trouble reading a configuration file. I validated both of my files against the DTD and they both validated fine. Is there something I am missing that could be causing this error? When I try to run the application I get this error in the error log: 28-Jun-2007 9:53:50 AM org.apache.catalina.core.StandardContext filterStart SEVERE: Exception starting filter struts2 Class: org.apache.xerces.framework.XMLParser File: XMLParser.java Method: parse Line: 1111 -
