Writing a simple HelloWorld application using Struts2.5. Getting the following error.

Looks like the Spring listener was not configured for your web app!
Nothing will work until WebApplicationContextUtils returns a valid ApplicationContext.
You might need to add the following to web.xml:
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

How can it be resolved without configuring Spring?

When running the above project in tomcat-8.0.43 container, getting my welecome page but when tried to test the action in browser http://localhost:8080/Struts2Starter/getTutorial.action it gives this
Error in browser
1.check in logs if:Hello from execute is printed
2. check if the jsp exists in the correct path
3. .action is not required at the end
4.<action name="getTutorial" class="org.awanish.action.TutorialAction" method="define your own method and try calling it">
5.Add jars at runtime also inside WEB-INF/lib folder
http://localhost:8080/Struts2Starter/getTutorial
And if you begineer try using struts 2.3 rather than struts 2.5 ,you will get lots of example:https://www.mkyong.com/struts2/struts-2-hello-world-example/
Download code and build on top of it if still facing issue
Yet another question on this I know, but let me just say I looked everything else or about. So, I'm currently building the structure of my Struts 2 Project. I use Struts 2.3.4, JBoss 7.1 and Eclipse Indigo. I also included all the necessary jar into my project. The problem is when I run my application (Add project to Jboss, Run On Server) and go "http://localhost:8080/booxstore/" I get this:
Etat HTTP 404 - There is no Action mapped for namespace [/] and action name [] associated with context path [/booxstore]

My 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">

<action name="afficher" class="com.booxstore.controller.DisplayAction" >
<result name="SUCCESS">/center.jsp</result>
</action>
</package>
</struts>
My action :
/**
*
*/
package com.booxstore.controller;
import com.opensymphony.xwork2.Action;
import com.opensymphony.xwork2.ActionSupport;
public class DisplayAction extends ActionSupport {
/**

private static final long serialVersionUID = 8199854978749642334L;
public String execute() throws Exception{
System.out.println("IN");
return Action.SUCCESS;
}
}
My JSP just have plain text and have imported struts 2 tags. Basically no matter what I do I can't get a resource. If I go to "http://localhost:8080/booxstore/" or "http://localhost:8080/booxstore/DisplayAction" I get "There is no action mapped" and if I tried to access directly the jsp I get a 404. Please note my war is deployed and enabled on the server.
Put index.jsp under WebContent folder, move pages folder to WEB-INF and then change the struts.xml with:
<struts>
<constant name="struts.devMode" value="false" />
<package name="pages" extends="struts-default">
<action name="afficher" class="com.booxstore.controller.DisplayAction" >
<result name="SUCCESS">/WEB-INF/pages/center.jsp</result>
</action>
</package>
</struts>
I think that the problem is that the application is not finding the jsps that you are putting in the configuration files. And META-INF folder is not the place for putting your jsps pages if you don't want to make them public, WEB-INF is better for that purpose.
To prevent misunderstandings about mappings, add the config browser plugin jar to your application. It will allow you to browse all pages. Caution! Only deploy the dependency in dev or testing, never ond production. Use maven profiles for this restrictions.

I am trying to run this example using struts 2. I inserted the libraries in the Lib folder of Web-Inf of a dynamic web project in eclipse.
My Web.xml looks like this now:
<?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" version="2.5">

</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
</web-app>
and i created the struts.xml and placed it inside the source folder , the content of which is
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
<!-- Configuration for the default package. -->
<package name="default" extends="struts-default">
<action name="UserAction" class="struts.UserAction">
<result name="input">/index.jsp</result>
<result name="success">/result.jsp</result>
</action>
</package>
</struts>
So now when i run any jsp i get the following error in eclipse console
Unable to load configuration. - bean - jar:file:/D:/Users/Don/workspace/.metadata/.plugins/org.eclipse.wst.server.core/tmp1/wtpwebapps/Mscs674-Struts2/WEB-INF/lib/struts2-gxp-plugin-2.3.4.jar!/struts-plugin.xml:8:162
and this on the webpage
HTTP Status 404 -
type Status report
message
description The requested resource () is not available.
Any suggestions ?
The best way i found to create struts 2 application is to use the struts-blank.jar file. It has all the required configurations done for you, and you can remove some example files. It will have all the jars and xml files created for you.
If you still have problems, try doing this now...
first remove all jar (adding all lib is not solution)
Only add necessary libraries
so problem is you are having too many lib
Seems like some jars are missing .. !!
The common dependecies are ::
commons-fileupload-1.2.1.jar
- commons-io-1.3.2.jar
- commons-logging-1.0.4.jar
- commons-logging-api-1.1.jar
- freemarker-2.3.15,jar
- log4j-1.2.14.jar
- ognl-2.7.3.jar
- xwork-core-2.1.6.jar
Check the version number and add jars to classpath.
You do One thing..add javassist-3.11.0.GA.jar file.it will remove your error like
Dispatcher initialization failed java.lang.RuntimeException:
java.lang.reflect.InvocationTargetException ..
I hope this will help you..
i am absolute beginner to Struts2. I am tying to follow tutorials on struts web site. i followed this tutorial. i have some trouble with it. i created dynamic web project on eclipse. Then i followed the tutorial. However when i run the example i get the following error.
There is no Action mapped for namespace [/] and action name [hello] associated with context path [/Hello_World_Struts_2]. - [unknown location]
i have the following directory structure
And my struts.xml file is
<?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" />
<package name="basicstruts2" extends="struts-default" namespace="/">
<action name="index">
<result>/index.jsp</result>
</action>
<action name="hello" class="org.apache.struts.helloworld.action.HelloWorldAction" method="execute">
<result name="SUCCESS">/HelloWorld.jsp</result>
</action>
</package>
</struts>
thanks for your responses.
The struts.xml configuration file needs to be on the classpath (as opposed to in WEB-INF).
The linked tutorial assumes a Maven build and states the struts.xml file should go in src/main/resources, which will be included in the classpath in Maven builds. Since you're ignoring that part, you'll likely want to put it in the root of your source directory.
You have to create a classes/ folder under WEB-INF/ and put in your struts.xml file!
Right click the project. Go to properties deployment build path and add all .jar files to /WEB-INF/lib. Then you shouldn't get this error.
struts.xml should be located under directory: src/struts.xml..
And WEB-INF/web.xml you we need to configure the struts based on filter..
I got the same error and got solution looking at tomcat log when restarting : doctype were missing in struts.xml
so I added
<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">
now it works !
I solved the issue by adding default-action-ref tag, for example,
<default-action-ref name="home" />
after package tag
in struts.xml
<package name="user" namespace="/" extends="struts-default">
<default-action-ref name="upload" />
I had the same issue and I was facing it because of not mentioning the namespace correctly in struts.xml.
I added the following snippet in the web.xml :
<welcome-file>login.jsp</welcome-file>
and also making the namespace as "/" default...
Hope it answers your query..
In my case I had to rename Struts.xml ---> struts.xml
This is my struts config file:
The root of my project is StrutsProject.
<?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="false" />
<package name="first" namespace="/helloworld" extends="struts-default">
<action name="HelloWorld" class="com.abc.actions.HelloWorldAction">
<result name="SUCCESS">/pages/login.jsp</result>
</action>
</package>
</struts>
I am trying to access the following URL:
http://localhost:8080/StrutsProject/helloworld/HelloWorld.action
I am getting the following error:

Please help,

Is your JSP file location is correct??
/pages/login.jsp
Or It should be
/WEB-INF/pages/login.jsp
