HelloWorldAction.java

    package com.struts2action;

    public class HelloWorldAction {

        public String execute() {
            System.out.println("HelloWorldAction - called");
            return "success";
        }
    }

I run and compile the program. I call the following:

http://localhost:8085/Struts2Test/hello.action

I keep getting the following error:

HTTP Status 404 - /Struts2Test/hello.action

type Status report message /Struts2Test/hello.action description The requested resource is not available.

Apache Tomcat/7.0.55

Could anyone please advise what the issue with my configuration is?

Solution 1

I've resolved my issue by removing the user-defined library and I added the jars directly to WEB-INF/classes folder. Please, note that the jars on the picture are different from the jars listed in my question. I am only starting to learn about Struts2 so I am not even sure whether I need all those jars in there. Either way, thanks you all for your help and feedback.

Solution 2

Try keeping the jar files inside /WEB-INF/lib

Solution 3

I tried the same code on Apache Tomcat 6.0 and It is working fine there.

On Tomcat7 you may need to use Struts2 Prepare and Execute Filter.

Try with replacing your filter code with following as Filter Dispatcher is97 deprecated now.

<filter-class>
org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
</filter-class>

Just one more question, are you able to see your System out statement on console?
