Hello,
your code and struts settings looks fine, so I guess the problem will be in the web.xml. How is set your Filter? What filter do you use? By the way, in struts page you sent, there is FilterDispatcher mentioned, but it is deprecated since 2.1.3. More about it here: http://struts.apache.org/2.1.6/struts2-core/apidocs/org/apache/struts2/dispatcher/FilterDispatcher.html <http://struts.apache.org/2.1.6/struts2-core/apidocs/org/apache/struts2/dispatcher/FilterDispatcher.html>Can you provide your complete web.xml?

Hello,
it seems to me that problem could exist at any of the two place. #Either action class's execute method is not getting called. Add SOPs with message variable in execute method to verify that. #Either your action class's execute method is getting called but the value of the message variable is not getting retained while jsp is getting called. Lets first check out of these two which is the cause of error, only then we can investigate further. if you can provide snippets from struts.xml and web.xml , that would be really helpful...

many thanks for both responses.
the web.xml looks as follows: <?xml version="1.0" encoding="UTF-8"?> <web-app id="WebApp_ID" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> <display-name>helloStruts</display-name> <welcome-file-list> <welcome-file>HelloWorld.jsp</welcome-file> </welcome-file-list> <servlet> <servlet-name>HelloWorld</servlet-name> <servlet-class>tutorial.HelloWorld</servlet-class> </servlet> <filter> <filter-name>struts2</filter-name> <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class> </filter> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> </web-app> i've removed references to the deprecated class but the result is still the same. it would appear that the execute method is not being called as i added the following code in there but saw nothing in the filesystem: try { BufferedWriter out = new BufferedWriter(new FileWriter("helloWorld")); out.write(MESSAGE); out.close(); } catch (IOException e) { } cheers, kostis

Hello,
couple of things: 1. Struts2 Action is not Servlet, so you don't need following part in your web.xml: <servlet> <servlet-name>HelloWorld</servlet-name> <servlet-class>tutorial.HelloWorld</servlet-class> </servlet> Based on your first email I assume that tutorial.HelloWorld is an action class, not Servlet. So please, remove this part. 2. Your action result page is also a welcome file, so if you run your application, it will display your HelloWorld.jsp file, but the Struts2 action will not be executed. (Check your address bar, if your URL ends with HelloWorld.jsp, this is the case). 3. So how to run your action? You have to call it... change the url so it ends with HelloWorld.*action, *this should trigger your action. You should probably know, that Struts is set by default to recognize only the *.action as Struts2 actions. Anything else is not treated as Struts2 action. You can change this in struts-default.xml if I am not wrong. But for this hello world example you don't need to do it. Just follow step 3 above to execute your action.
