We have a Tomcat 4.1.31 running in a JVM 1.4.2_09 on our server (yes an upgrade is overdue). I've built a Jakarta Struts application and have previously deployed it successfully. However, I have since made some changes to the source code and when trying to deploy the WAR file back to Tomcat I get the following error:
javax.servlet.UnavailableException: Parsing error processing resource path /WEB-INF/struts-config.xml at org.apache.struts.action.ActionServlet.initApplicationConfig(ActionServlet.java:780) at org.apache.struts.action.ActionServlet.init(ActionServlet.java:417) at javax.servlet.GenericServlet.init(GenericServlet.java:212) ...
By trial and error, I've found that I can successfully deploy the WAR if I remove all my <action-mappings> declarations from the struts-config.xml which of course leaves me dead in the water.
I have a feeling this has to be a Tomcat issue and not a struts issue since I can delpoy it successfully on my own machine (using the same Tomcat version and JVM environment). I have also tried creating a bare bones struts app with a single action class, but I still get this error (unless I remove the <action-mappings> of course).
So far I've tried placing the struts.jar in the common/lib directory as well as the server/lib directory (which probably isn't necesary). I have also tried downloading the struts-config_1_1.dtd and referencing it directy from the struts-config.xml file rather than through http.
Here is the struts-config.xml file of the bare bones app (it's smaller):
<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.1//EN" "http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd">
