Not sure where to submit an bug report, since the JIRA link seems to be broken... So, I am posting it here.
Blank Extensions break the normal processing of non-action files. web.xml: -------------------------------------------------------------------------- <?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xmlns=" http://java.sun.com/xml/ns/javaee"; xmlns:web=" http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"; xsi:schemaLocation=" http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"; id="WebApp_ID" version="2.5"> <display-name>WebSite</display-name> <filter> <filter-name>struts2</filter-name> <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class> <init-param> <param-name>actionPackages</param-name> <param-value>com.example.actions</param-value> </init-param> </filter> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> </web-app> struts.xml: -------------------------------------------------------------------------- <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" "http://struts.apache.org/dtds/struts-2.0.dtd"; > <struts> <constant name="struts.devMode" value="true"/> <constant name="struts.action.extension" value=""/> <package name="default" extends="struts-default"> <action name="home"> <result>/home.jsp</result> </action> </package> </struts> In addition to these two xml files, I have two image files and two jsp files: /logo.gif /images/logo.gif /index.jsp /home.jsp The image files are unique so I know which is being displayed. The JSP files are unique so I know which is being displayed. (ie "this is home" and "this is index") Results: --------------------------------------------------------------------- I have gone to each of the specified URLs, with the following results: /home This works as expected. I see a page that says "this is home" /home.jsp Error page with the message: There is no Action mapped for namespace / and action name home.jsp /index.jsp Error page with the message: There is no Action mapped for namespace / and action name index.jsp / Error page with the message: There is no Action mapped for namespace / and action name index.jsp /logo.gif Error page with the message: There is no Action mapped for namespace / and action name logo.gif /images/logo.gif Error page with the message: There is no Action mapped for action name logo.gif I believe this is not the intended result. I would expect the same results that I get if I set the extension to "action" (with the corresponding URLs) These results are as follows: /home.action This works as expected. I see a page that says "this is home" /home Error 404 (expected result) /home.jsp I see a page that says "this is home", but it is not the result of the action (parameters in the action are not processed) /index.jsp This works as expected. I see a page that says "this is index" / This works as expected. I see a page that says "this is index" /logo.gif Works as expected, I see the logo image. /images/logo.gif Works as expected, I see the other logo image. I consider this a bug, since the behavior is quite different between the two scenarios. Restating it again, I expect the same behavior when the extension is blank as when it is "action" or "do" or "fred", except there is no extension. I also expect non-actions to be processed as normal. Expected solution: When an extension is specified, the actual action name is the concatenation of the specified action name plus the extension. For example: "home.action". Requests that don't match the "actual" action name, are considered normal file requests. When a blank extension is specified, the actual action name is exactly what is specified in the action name, without the addition of the extension. For example: "home". But other requests that don't match specified action names would be considered normal file requests. (BTW, with blank extensions the action name may specify an extension, for example "home.do") Phil
