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>

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>
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
Before starting, I'm sorry for my bad English, because English is not my first language. However, I have a problem with Struts 2 redirecting.
One part of my Struts.xml file is like this:
<package name="login" namespace="/" extends="struts-default">
<action name="login" class="Action.loginAction">
<result name="success" type="redirectAction">
<param name="actionName">search</param>
<param name="namespace">/</param>
</result>
<result name="error">/login.jsp</result>
<result name="input">/login.jsp</result>
</action>
</package>
I have a loginAction that's responsible for logging in the user (no matter what is the content of this file). When the result of this action is success, I want to redirect to search action. Everything works fine, but my problem is, when I redirect to search action, the URL looks like this: http://localhost:8080/MyWebApplication/search.action
I want to have the .action removed from the URL, when redirecting to a particular action. What do I need to change to fix this?
Thanks for your attention.
By default struts2 framework will add .action you can override it by following configuration.
<constant name="struts.action.extension" value=""/>
For ref:
http://struts.apache.org/release/2.3.x/struts2-core/apidocs/org/apache/struts2/dispatcher/mapper/DefaultActionMapper.html
With some help of the people here, I've managed to get my project to call the default actions of the packages without the suffix .htm. However, the request end up to index.jsp inside the webapp folder if I call the URL without the forward slash.
<struts>
<constant name="struts.enable.DynamicMethodInvocation" value="false"/>
<constant name="struts.action.extension" value="htm,," />
<constant name="struts.objectFactory" value="spring" />
<constant name="struts.devMode" value="true"/>
...
<package name="home" namespace="/secured" extends="default">
<default-action-ref name="index" />
<action name="index" class="homeAction" method="execute">
<result name="success" type="tiles">home</result>
</action>
</package>
</struts>
Actions are executed if I call http://someurl/someproject/secured/, but calling the URL http://someurl/someproject/secured end up to the file index.jsp.
What to do? Thanks
When you are calling http://someurl/someproject/secured url the secured is treated like action w/o suffix, because you have configured that actions can have empty suffix (which is also default btw). If you want that this url redirects to /secured namespace you can declare secured action with redirectAction result in package with empty or / namespace.
<package name="..." namespace="/" extends="struts-default">
...
<action name="secured">
<result type="redirectAction">
<param name="actionName">index</param>
<param name="namespace">/secured</param>
</result>
</action>
...
</package>
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.
