java - Tomcat giving Error : "There is no Action mapped for action name" in Struts 2 -

-

this question has answer here:

tried changing location of struts.xml still getting error. namespace being used in url still getting error.

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" namespace="/program" extends="struts-default">          <action name="gettwo" class="strutstwopack.programtwo">             <result>/success.jsp </result>             <result>/failure.jsp</result>         </action>             </package>     </struts>

web.xml:

<?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" xsi:schemalocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="webapp_id" version="3.0">   <display-name>strutsstart</display-name>   <welcome-file-list>     <welcome-file>index.html</welcome-file>     <welcome-file>index.htm</welcome-file>     <welcome-file>index.jsp</welcome-file>     <welcome-file>default.html</welcome-file>     <welcome-file>default.htm</welcome-file>     <welcome-file>default.jsp</welcome-file>   </welcome-file-list>     <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>    </web-app>

action class:

package ninad.struts2one;  import service.programbest;  public class programoneaction {      private string bestprog;     private string lang;      public string execute()     {         programbest pb = new programbest();         setbestprog(pb.givebestprogram(getlang()));         system.out.println(bestprog);         //system.out.println(getlang());         return "success";     }      public string getbestprog() {         return bestprog;     }      public void setbestprog(string bestprog) {         this.bestprog = bestprog;     }      public string getlang() {         return lang;     }      public void setlang(string lang) {         this.lang = lang;     }   }

service class:

package service;  public class programbest {      public string givebestprogram(string lang) {         if (lang.equals("java")){         return "my code";         }         else             return "no other code";     }  }

the url enter in apache window :

http://localhost:8484/strutsstart/program/programone.action

the error is: 

there no action mapped action name programone. - [unknown location]

you have posted question

'there no action mapped action name gettwo' in struts2

the action gettwo mapped class strutstwopack.programtwo in namespace /program. if error true means either class wrong or namespace wrong in url.

what should do???

post sscce, or decide wrong version better resolvable.
