There is no Action mapped for namespace [/] and action name [login] associated with context path [/Struts2Test]

Closed 2 years ago.
Currently migrating an app from Struts1 to Struts2.
When I click my "submit" button, it gives me an error saying "There is no Action mapped for action name requestInput". What is wrong with my code that is the cause of this error?

And, my struts.xml is in the Java src folder and in the WEB-INF folder.
What else can I do to fix this? Thanks..
Two issues, otherwise looks good.
First issue:
action name="requestInput" class="com.class.action.FileAddAction"
method="execute"
You can't name your package with the identifier class, it is not a valid Java identifier
Second issue:
interceptor-ref name="uploadForm"
What is "uploadForm"? It's definitely not provided by Struts 2, see the list.
By naming the package differently, and removing interceptor-ref uploadForm, i am able to click the FileAdd.jsp Submit button without any issue and it is redirecting me successfully to result.jsp. I used v2.3.37.
Note:
struts.xml should be in the src/main/resources folder (struts.xml must be on the web application’s root class path). Check this out.
web.xml is to be under src/main/webapp/WEB-INF folder. Check this out.

i have a problem loading a page. I defined in the struts.xml (located in Java Resources/src/com.infopool.action) the next configuration:
<struts>
<package name="demo" namespace="/demo" extends="struts-default">
<action name="Inicio" class="com.infopool.action.Demo">
<result name="success">/View/demo/start.jsp</result>
</action>
<action name="Hola" class="com.infopool.action.Demo" method="hello">
<result name="success">/View/demo/hello.jsp</result>
</action>
<action name="Chau" class="com.infopool.action.Demo" method="goodbye">
<result name="success">/View/demo/goodbye.jsp</result>
</action>
</package>
</struts>
So, in the package com.infopool.action i have the next class defined:
package com.infopool.action;
public class Demo {
public String execute(){
return "success";
}
public String hello(){
return "success";
}
public String goodbye(){
return "success";
}
}
The views are located into WebContent/View/demo. When i try to browse the page, an 404 Tomcat error appear. The URL is:
http://localhost:8080/Infopool/demo/Inicio.action
My web.xml have the next configuration:
<filter>
<filter-name>Main</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
<init-param>
<param-name>actionPackages</param-name>
<param-value>com.infopool.action</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>Main</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
What is wrong with my configuration ?.
the use of this one is to pass an action package where all the action classes has been declared
<init-param>
<param-name>actionPackages</param-name>
<param-value>com.infopool.action</param-value>
</init-param>
but your Demo action class doesnt have any annotation configuration like (if im not mistaken.)
#Namespace("/demo")
#Action("/Inicio")
#ResultPath(value="/")
#Result(name="success",location="/View/demo/start.jsp")
public class Demo {
....
You used the other way on configuring your action class which is your struts.xml
<struts>
<package name="demo" namespace="/demo" extends="struts-default">
<action name="Inicio" class="com.infopool.action.Demo">
<result name="success">/View/demo/start.jsp</result>
</action>
<action name="Hola" class="com.infopool.action.Demo" method="hello">
<result name="success">/View/demo/hello.jsp</result>
</action>
<action name="Chau" class="com.infopool.action.Demo" method="goodbye">
<result name="success">/View/demo/goodbye.jsp</result>
</action>
</package>
</struts>
so no need to declare/create this,
<init-param>
<param-name>actionPackages</param-name>
<param-value>com.infopool.action</param-value>
</init-param>
inside of your struts filter.

Libs I have added:

Error accessing URL:
http://localhost:8080/StrutsHelloWorld/
HTTP Status 404 - /StrutsHelloWorld/
type Status report

description The requested resource is not available.

I tried this tutorial.
There are no errors on my console, problem view.
The error 404 means that resource you have requested is not available, the same referred to the action that is didn't map to the request URL.
FilterDispatcher is deprecated and may not work with the current Struts version, use StrutsPrepareAndExcecuteFilter instead.
<filter>
<filter-name>struts2</filter-name>
<filter-class>
org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
in the struts.xml add the following
<package name="default" extends="struts-default" namespace="/">
<action name=""><result>/Login.jsp</result></acton>
this will forward you to the login page. Also consider to use absolute paths to the JSP resources.
In the JSP use the form that needs to rewrite to
<s:form namespace="/" action="login" method="post">
<s:textfield name="username" key="label.username" size="20" />
<s:password name="password" key="label.password" size="20" />
<s:submit key="label.login" align="center" />
</s:form>
In the action attribute use the action name and provide namespace as you did in the package configuration.
Using method="execute" is useless in the s:submit tag, the method execute used by default, and it will not work because you have turned off DMI in the Struts configuration.
Adding libraries over the old libraries in the WEB-INF/lib doesn't help so much and your application probably would not work, until you remove and replace all lower version libraries with higher version and add new libraries needed by the current version of Struts framework.
for me it's I didn't add "lang3" to library, after adding it everything goes well
I have a project using struts 2.1.8. The project is configured by annotation using struts2-convention-plugin. Here is my struts config in web.xml:
<filter>
<filter-name>struts2Filter</filter-name>
<filter-class>
org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2Filter</filter-name>
<url-pattern>*.jsp</url-pattern>
</filter-mapping>
<filter-mapping>
<filter-name>struts2Filter</filter-name>
<url-pattern>/struts/*</url-pattern>
</filter-mapping>
struts.xml:
<constant name="struts.convention.default.parent.package" value="borrow-default" />
<constant name="struts.convention.package.locators" value="action" />
<constant name="struts.convention.package.locators.basePackage" value="com.abc.action" />
<constant name="struts.convention.result.path" value="/" />
A.java:
#Namespace("/regist")
public class A extends ActionSupport{
#Action(value="/a", results = {#Result(location = "/a/test.jsp")})
public String execute(){
return SUCCESS;
}
}
Here is the problem, I can access the test.jsp in url http://localhost:8080/a/test.jsp and http://localhost:8080/regist/a.action, but I can still visit the same page in url http://localhost:8080/a/test.action. I don't know why this happens, what's wrong in my config or code?
I also tried some other url, it seems the namespace doesn't take effect.
In web.xml your url pattern is like:
<url-pattern>/struts/*</url-pattern>
but you are placed jsp and getting it from /a/test.jsp
once check it...
I upgraded the struts to 2.3.15.1 and this question disappeared
I am new java struts framework. But I want to ask a question.
In struts.xml path is .do like "/AddReq.do" OR path is only name like "AddReq"
What is difference between "/AddReq.do" and "AddReq" ?
For example
<action path="/AddReqPage"
type="...actions.AddReqPageAction">
<forward name="success" path="AddReq" />
<forward name="failure" path="/bos.jsp" />
</action>
<action path="/AddReq"
type="...actions.AddReqAction"
name="AddReqForm" validate="true"
scope="request">
<forward name="success" path="/AddReqDetail.do" />
<forward name="hata" path="AddReq" />
<forward name="failure" path="/bos.jsp" />
</action>
Not much difference. Both should work - provided you map to struts ActionServlet correctly in your web.xml.
<servlet-mapping>
<servlet-name>action</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
Conventionally, struts uses *.do pattern to distingush its servlet from other servlets and JSPs
".do" is a action extension. You configure it in servlet mapping. When struts parses the url it's looking for such extension to distinguish static calls from the struts action. Then finds the mapping that correspond that URL but without ".do ". However, you have still specify ".do" in the forwards if your application configured to use that extension. Nowadays, this extension has less meaning as before. The URL rewrite technique brings to completely ignore that extension. With
<servlet-mapping>
<servlet-name>action</servlet-name>
<url-pattern>/c/*</url-pattern>
</servlet-mapping>
and reference above you could completely dismiss it.
I am using struts2 for developing a web application.
I have include the required jars for struts2 but when it is going to call the struts action class it is throwing 404 error.
There is no error on console and browser does not showing .action extension whitch it shows when struts.xml call an action class.
I am using jdk 1.6 and struts 2.0.
Am I missing any jar who is responsible for all this.
In jsp I am simply calling the function from
<s:form action = "Mergexmlaction" method = "post"/>
Here is my struts.xml and web.xml

There are a few issues.
<package name="default" namespace="/jsp" extends="struts-default">
1) I'd recommend against having a namespace of "jsp", it doesn't make any sense. Namespaces should be something meaningful to the application and/or user.
<action name="Mergexmlaction" class="com.hm.merge.mergeaction.Mergexmlaction">
2) Don't name an action with "action", there will either be a .action extension, or no extension at all. Either way, there's no reason to duplicate "action" in the first case, and no reason to use "action" if there's no extension. Just "mergexml", "mergeXml", etc.
<result name="success" >/jsp/Result.jsp</result>
3) I recommend putting your JSP pages under WEB-INF to avoid direct client access.
<interceptor-ref name="fileUpload">
4) Once you declare any interceptors, you must declare all interceptors. This action has only a single interceptor running. It's possible this is okay, but it's almost never the right thing to do.
<welcome-file>jsp/Browse_multiplexmlfiles.jsp</welcome-file>
5) And this is the ultimate issue, depending on how you're accessing the application. You show the welcome file as being a JSP page, which is presumably using S2 tags. This won't work: the tags depend on their being a complete S2 request, a value stack, etc.
All access to an S2 app should take place through an S2 action, not a JSP. If you look at the rendered HTML for the directly-accessed JSP you'll see neither namespace nor action extension rendered.
an error 404 is a bad link. means you just are calling a link that doesnt exist. Check your mapping in your struts config file and make sure you use the correct url.
The namespace attribute of package element is optional and if it is not present, the default value "/" is assumed. If the namespace attribute has a non-default value, the namespace must be added to the URI that invokes the actions in the package.
For example, the URI for invoking an action in a package with a default namespace is this:
/context/actionName
To invoke an action in a package with a non-default namespace, you need this URI:
/context/namespace/actionName
