Struts unable to find action class - java

Been banging my head for quiet sometime now as I don't seem to understand why struts is unable to find my action class.
This is 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">
<struts>
<package name="default" extends="struts-default">
<action name="getTutorial" class="org.mypackage.actions.TutotrialAction" method="execute">
<result name="success">/success.jsp</result>
<result name="failure">/error.jsp</result>
</action>
</package>
</struts>
This is my project structure
And finally this is the error that I see
Clearly the action seem to be present, not sure why it is unable to find it. Another eye ball would be appreciated!

Small typo:
<action name="getTutorial" class="org.mypackage.actions.TutotrialAction" method="execute">
^
should be
<action name="getTutorial" class="org.mypackage.actions.TutorialAction" method="execute">

How can I map the root path of my web application using struts2?

When I run my strust2 web application, I want to execute an action for the root path [/].
It would be something like an action with no name or just "/", something like:
<action name="/" class="ControllerName" method="execute">
<result name="success">ShowTheFirstPageAfterTheAction.jsp</result>
</action>
...
<struts>
...
<package name="user" namespace="/" extends="struts-default">
<action name="" class="ControllerName" method="execute">
<result name="success">ShowTheFirstPageAfterTheAction.jsp</result>
</action>
// Other actions depending on how you've designed your application
<package
// Other packages (also) depending on how you've designed your application
</struts>

Struts2: Setting constant struts.action.extension to "," not working

I am working on struts2-archetype-starter. Got a demo struts 2 project by executing:
mvn archetype:generate -B -DgroupId=demoStrutsStarter -DartifactId=DemoStrutsStarter -DarchetypeGroupId=org.apache.struts -DarchetypeArtifactId=struts2-archetype-starter
I modified my struts.xml and added a struts.action.extension constant declaration. Now it looks like this:
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
"http://struts.apache.org/dtds/struts-2.3.dtd">
<struts>
<constant name="struts.action.extension" value=","/>
<constant name="struts.enable.DynamicMethodInvocation" value="false"/>
<package name="myPackage" extends="struts-default">
<default-action-ref name="index" />
<action name="index" class="demoStrutsStarter.IndexAction">
<result>/jsp/index.jsp</result>
</action>
<action name="helloWorld" class="demoStrutsStarter.HelloWorldAction">
<result name="input">/jsp/index.jsp</result>
<result>/jsp/helloWorld.jsp</result>
</action>
</package>
</struts>
But, I am getting a 404 error when I type:
http://localhost:8080/DemoStrutsStarter/index
I am not sure where I am wrong. Can anybody please help me find out why I am unable to call actions without .action extension?
Try adding a namespace to your package:
<package name="myPackage" namespace="/" extends="struts-default" >
Try this out in both results
result 1
<result>/WEB-INF/jsp/index.jsp</result>
result 2
<result>/WEB-INF/jsp/helloWorld.jsp</result>
else check your package name is correct or not.
by default, it's name default
try this links. it may help
1.stack overflow link 1
2.link 2 mkyong
3.stack overflow link 3

Get Request in Struts 2

I am new to struts2. In application there is Action called userLogin. when i enter to url http://servername:9090/appName/userLogin, It should forward the request directly to to /jsp/account/login.jsp. it should not call action method. how can i ensure that when request is through get then forword to loginPage else if Request is Post then it should call the action
Struts.xml is as follows
<?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" />
<constant name="struts.custom.i18n.resources" value="ApplicationResources" />
<package name="default" extends="struts-default">
<action name="index">
<result>jsp/index.jsp</result>
</action>
<action name="userLogin" class="com.ril.tc.action.LoginAction">
<result>jsp/account/login.jsp</result>
<result name="success">jsp/index.jsp</result>
<result name="error">jsp/account/login.jsp</result>
</action>
<action name="ministatement" class="com.ril.tc.action.MiniStatementAction">
<result>jsp/account/ministatement.jsp</result>
<result name="success">jsp/account/ministatementdetails.jsp</result>
<result name="error">jsp/account/ministatement.jsp</result>
</action>
</package>
</struts>
1. You can simply check the request method in action method before the business method executes.
It will add 2-3 lines of java code in action method and a line modification in xml configuration.
2. Or you can strictly restrict the execution of the Action method by using an interceptor.
Interceptor requires a seperate java class and a few lines of xml configuration.
Method 1
a) Java code
public String execute (){ // or your method name
if(ServletActionContext.getRequest().getMethod().equals("GET")){
return "getrequest";
}
........
//your business logic
}
b) xml configuration
<action name="userLogin" class="com.ril.tc.action.LoginAction">
<result name="getrequest">jsp/account/login.jsp</result>
<result name="success">jsp/index.jsp</result>
<result name="error">jsp/account/login.jsp</result>
</action>
Method 2.
a) Java Code
public GetRequestFilterInterceptor extends AbstractInterceptor{
#Override
public void intercept (ActionInvocation action){
if(ServletActionContext.getRequest().getMethod(). equals("GET")){
return "getrequest";
}else{
action.invoke();
}
}
}
b) Xml configuration
<struts>
<package name="default" extends="struts-default">
<interceptors>
<interceptor name="getUrlFilter" class="packagename.GetRequestFilterInterceptor"/>
<interceptor-stack name="requestFilter">
<interceptor-ref name="getUrlFilter"/>
<interceptor-ref name="defaultStack"/>
</interceptor-stack>
</interceptors>
......
<action name="userLogin" class="com.ril.tc.action.LoginAction">
<interceptor-ref name="requestFilter"/>
<result name="getrequest">jsp/account/login.jsp</result>
<result name="success">jsp/index.jsp</result>
<result name="error">jsp/account/login.jsp</result>
</action>
</package>
</struts>
I recommend you to use interceptors, if you want to filter a lot a methods. If you have want to filter only one method, the first one is better.

How to remove the extensions from url

I have designed an application using struts2, and need to remove the extensions for example
www.myweb.com/register.action
How to remove the .action so when I click on register it call www.myweb.com/register without action extension?
I use the following
Register
I've found the answer. I should change the struts configuration as following:
<struts>
<constant name="struts.action.extension" value=""/>
<package name="default" extends="struts-default">
<action name="register">
<result type="tiles">register</result>
</action>
</package>
</struts>

Resource ... is not available

If i try to use this action (test2) it always returns "The requested resource (/WebApplication4/newFolder/test2.jsp) is not available."
Running tomcat6 and netbeans 6.7.1
config.xml (it is included in 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">
<struts>
<package name="mypackage" namespace="/" extends="struts-default">
<action name="test2">
<result>/newFolder/test2.jsp</result>
</action>
</package>
</struts>
alt text http://img2.pict.com/87/b7/dc/1676731/0/clipboard4.jpg
but if i change result value from "/newFolder/test2.jsp" to "test.jsp" - everything works.
Solved, needed:
<result>/WEB-INF/newFolder/test2.jsp</result>
