Hello Everyone,

I am creating a sample application in Struts 2 but i am getting stuck due to some jar file missing used for the taglib.

My Programs are lke this:

My Pojo class:

My Action class:

My first jsp page:

My second jsp page:

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">

<default-action-ref name="index" />

<global-results>
            <result name="error">/error.jsp</result>
        </global-results>

<global-exception-mappings>
            <exception-mapping exception="java.lang.Exception" result="error"/>
        </global-exception-mappings>

<action name="index">
       <result>/index.jsp</result>
       </action>
       
       <action name="welcome" class="com.bs.MessageAction" method="execute">
       <result name="success">/Welcome.jsp</result>
       </action>
    </package>

</struts>

My web.xml file:

Also I am using these jar files for my application:

struts2-core-2.2.3.jar
srtuts2-convention-plugin-2.2.3.jar
struts2-config-browser-plugin-2.2.3.jar

On deploying my application in Apache Tomcat 7

I am getting this type of error:

type Exception report

message

description The server encountered an internal error () that prevented it from fulfilling this request.

exception

note The full stack trace of the root cause is available in the Apache Tomcat/7.0.14 logs.

Which handler class is the Tomcat server talking about:
For struts-tags.tld file, I already knew that this tld file is stored in
struts2-core-2.2.3.jar file and I am using it too then why am i getting this type of error:

Also, What other jar files do i need for running my application.

Any reply for this topic is highly appreciable............

Thank You
