this is default implementation.
<welcome-file-list>
<welcome-file>Index.jsp</welcome-file>
</welcome-file-list>
i want to change like below
<welcome-file-list>
<welcome-file>login.action</welcome-file>
</welcome-file-list>
<action name="login" class="com.mm.authentication.Login">
<result name="success">/Index.jsp</result>
above implementation not working.
if anyone know how to do this, please let me know.
The welcome file is just a file. You have to rename it to something login.jsp. But create a new file index.jsp with the following content
<% response.sendRedirect(request.getContextPath()+"login.action"); %>
The action configuration
<action name="login" class="com.mm.authentication.Login">
<result name="success">/login.jsp</result>

I am new to Struts 2 and I have been following a video tutorial on Struts 2(Koushik). I have created the Struts.xml, the action class and JSPs as same as created in the tutorial. But it gives the following exception.
Exception:

Project structure
success.jsp and error.jsp are normal jsp files with some text. I did a lot of things to resolve this issue by googling. But nothing didn't solve this. Please let me know if anyone knows what's behind this. I highly appreciate it. :)
Renaming Struts.xml naming convention to struts.xml will work.
The message from error clearly says that
no Action mapped for namespace [/] and action name [getTutorial]
associated with context path [/Struts2Starter]
This means that action configuration is not available at runtime. Check out the config-browser plugin to debug configuration issues.
To map correctly url to the action two parameters are required: the action name and namespace.
Struts loads xml configuration on startup and it should know the location of the struts.xml. By default it's looking on classpath to find a file with known name like struts.xml. Then it parses document and creates a runtime configuration. This configuration is used to find appropriate configuration element for the action url. If no such element is found during request, the 404 error code is returned with the message: There is no Action mapped for namespace and action name.
Also this message contains a namespace and action names used to find the action config. Then you can check your configuration settings in struts.xml. Sometimes the action name and namespace, stored in ActionMapping point to the wrong action. These values are determined by the ActionMapper which could have different implementation, used by plugins.
There's also another setting that might affect this mapper and mapping, but the point is the same if you get this message then URL is used didn't map any action config in runtime configuration. If you can't realize which URL you should use, you might try config-browser plugin to see the list of URLs available to use.
change your Struts.xml and put <constant name="struts.devMode" value="true" /> in struts.xml Development mode or devMode it enables extra debugging and helps indebugging
try below code
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC

</action>
</package>
</struts>
U just need to check that action name is constant everywhere...i also had same problem i resolved by removing namespace as it is not necessary which i see u have not mentioned and also i had different action name at loginpage.jsp and struts.xml page.. so just see ur action name
Your JSP file should not be under the WEB-INF folder, but should be under the web folder. I've attached an image to show you the right hierarchy.

I'm trying to create a simple Struts 2 JSR 286 Portlet, running on WebSphere Portal 7. I'm able to display a simple JSP that contains a link which calls an action and displays another JSP which accepts input. That works fine.
I start to run into problems, however, when I try to use a redirectAction. I don't see any error messages, but the redirect doesn't seem to work. The Portlet just shows a blank page.
In debugging this I noticed that the doView method of my Portlet class is never called, which seems very suspicious.
If anyone has experience developing Struts 2 Portlets on WebSphere Portal, I would appreciate some help in checking that my config files are correct. Have I missed something?
Here are the details:
WebSphere Portal 7.0.0.2
WebSphere Application Server 7.0.0.25
RAD 8.0.4
Struts 2.3.14.2
Windows 7

* Update *
I've narrowed the problem down slightly. It looks like the action is being interpreted as a file location rather than a struts action. So, when I call action "redirectToIndex" it tries to display a page called "/view/index.action". I verified this by creating a file with that path and sure enough, the contents of that file are displayed in the portlet.
I feel that I'm probably missing some configuration option, but I'm not sure what. Servlet filter maybe? Can anyone help?
Actually you don't need doView method, because Jsr286Dispatcher is just a dispatcher. You can use actions like in ordinary Struts2 application.
From the documentation:
The portlet-class element is always org.apache.struts2.portlet.dispatcher.Jsr168Dispatcher (or a subclass, if you have added some custom functionality). This is the portlet that acts as the dispatcher for the Struts 2 framework, and translates incoming user interaction to action requests that Struts 2 understands.
For jsr286 specification <portlet-class> should be org.apache.struts2.portlet.dispatcher.Jsr286Dispatcher and defaultViewAction init-param will call Struts2 action. And in struts.xml file, like usually, you can define action class + method to call.
So you need to define Jsr286Dispatcher as <portlet-class> and create action which you will use in struts.xml action definitions.
Also see this two links: http://struts.apache.org/development/2.x/docs/struts-2-portlet-tutorial.html and http://struts.apache.org/development/2.x/docs/portlet-plugin.html.

Closed 6 years ago.
I have several problems and I would if someone can help me to solve this with Struts 2. This is the problem I have. When I run my simple Login Application I have this mistake:
org.apache.jasper.JasperException: The Struts dispatcher cannot be found.
This is usually caused by using Struts tags without the associated filter. Struts tags are only usable when the request has passed through its servlet filter, which initializes the Struts dispatcher needed for this tag. - [unknown location]
The log is this one:
Advertencia: StandardWrapperValve[jsp]: PWC1406: Servlet.service() for servlet jsp threw exception
The Struts dispatcher cannot be found. This is usually caused by using Struts tags without the associated filter. Struts tags are only usable when the request has passed through its servlet filter, which initializes the Struts dispatcher needed for this tag. - [unknown location]

The file tree is this one:
src(es.uniway.action.login as a package and inside this class:
LoginAction.java:

import com.opensymphony.xwork2.ActionSupport;
public class LoginAction extends ActionSupport{
#Override
public String execute() throws Exception {
// TODO Auto-generated method stub
return SUCCESS;
}
}
As well inside of the src I have the struts.xml:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC

<result name="input">/Login.jsp</result>
<result name="success" type="redirectAction">/index.jsp</result>
</action>
</package>
<!-- Add packages here -->
</struts>
Then at web-info folder I have the web.xml which I have this thing:

And after that at WebContent I have index.jsp and Login.jsp which I have this code:
<%# page contentType="text/html; charset=UTF-8" %>
<%# taglib prefix="s" uri="/struts-tags" %>

And the libraries at the lib folder inside of the WEB-INF are : asm-3.3.jar, asm-commons-3.3.jar, asm-tree-3.3.jar, commons-fileupload-1.2.2.jar, commons-io-2.0.1.jar, commons-lang3-3.1.jar, freemarker-2.3.19.jar, javassist-3.11.0.GA.jar, ognl-3.0.5.jar
, struts2-core-2.3.3.jar, xwork-core-2.3.3.jar . Please, what I'm doing wrong?
Do this
Change
<action name="Login" class="com.uniway.action.LoginAction">
<result name="input">/Login.jsp</result>
<result name="success" type="redirectAction">/index.jsp</result>
</action>
To
<action name="Login" class="com.uniway.action.LoginAction">
<result name="input">/Login.jsp</result>
<result name="success">/Login.jsp</result>
</action>
Change this
<s:form action="Login.action">
To
<s:form namespace="/" action="Login">
Next
Change
<s:submit method="execute"/>
To
<s:submit value="Login"/>
I had this problem with my 404.jsp page and this was my solution:
We should not use <s: tags in 404.jsp!!!
I don't know why, but this solved my problem!
I have been trying to get through an example of tiles based program in struts.
I am using a very simple program. Inside web.xml, I am calling a listener class as shown.
<listener>
<listener-class>
org.apache.struts2.tiles.StrutsTilesListener
</listener-class>
</listener>
Whenever I include this lines in web.xml, my program shows a HTTP status 404 error.
Can anyone tell me what is wrong with this listener class?
Another problem is I am unable to map from struts.xml to tiles.xml.
I am not 100% sure whether this latter problem is because of non-inclusion of that listener class so as to allow my program to run. Just to clarify that doubt also, consider my part of struts.xml file.
Struts.xml
<action name="login" class="Myclass">
<result name="success" type="tiles">/WelcomeFile.tiles</result>
</action>
tiles.xml
<definition name="/WelcomeFile.tiles" extends="BaseLayout">
<put-attribute name="body" value="myFile.jsp" />
So is it necessary that files should be extended by .tiles. Please clarify on this.
Basically when the user goes to example.com I want to serve it the same content I would have, if it went to example.com/news. Below is the code snippet.
Current COnfig
<action name="" class="action.public.news">
<result>/jsp/labs/listLabs.jsp</result>
</action>
<action name="news" class="action.public.news">
<result>/jsp/labs/listLabs.jsp</result>
</action>
Desried COnfig
<action name="" class="action.public.news">
Use Action Named "news" instead
</action>
<action name="news" class="action.public.news">
<result>/jsp/labs/listLabs.jsp</result>
</action>
If i understand it right you want that when user hit the base domain example.com it should fetch the content of the action news one way to do this is.
create an empty file name welcome in your web-content folder.Add following entry to your web.xml
<filter>
<filter-name>action2</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>action2</filter-name>
<url-pattern>/*</url-pattern>
<dispatcher>REQUEST</dispatcher>
<dispatcher>FORWARD</dispatcher>
<dispatcher>INCLUDE</dispatcher>
<dispatcher>ERROR</dispatcher>
</filter-mapping>
replace your welcome list file in web.xml as
<welcome-file-list>
<welcome-file>welcome</welcome-file>
</welcome-file-list>
and finally in your strus.xml do something like
<action name="welcome" class="action.public.news">
<result>/jsp/labs/listLabs.jsp</result>
</action>
what we are trying to do is that when we hit example.com instead of showing the welcome jsp file we are hitting the action and using its result
Most people create a index.jsp page in the webapp folder containing this:
<% response.sendRedirect("index.action"); %>
This will redirect the visitor to the index.action when they arrive at your domain. Then, in struts.xml:
<action name="index" class="action.public.news">
<result>/jsp/labs/listLabs.jsp</result>
</action>
Cheers,
Christian
