Internal Server error while calling an Java method from JSP

This is my JSP

extra.jsp:

<%@taglib uri="http://struts.apache.org/tags-bean" prefix="bean"%>
<html>
<head>
</head>
<body>
<h1><bean:write name="HelloWorldForm" property="message">
</h1>
</body>
</html>

this formBean

HelloWorldForm.java:

package com.redhat.rhn.frontend.action.common;
import org.apache.struts.action.ActionForm;
public class HelloWorldForm extends ActionForm{
    String message="HelloWorld!";
    public String getMessage() {
            return message;
    }
    public void setMessage(String message) {
            this.message = message;
    }
}

this is action

HelloWorldAction.java:

package com.redhat.rhn.frontend.action;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;

import com.redhat.rhn.frontend.action.common.HelloWorldForm;

public class HelloWorldAction extends Action{
    public ActionForward execute(ActionMapping mapping,ActionForm form,
            HttpServletRequest request,HttpServletResponse response)
    throws Exception {
            HelloWorldForm HelloWorldForm = (HelloWorldForm) form;
            HelloWorldForm.setMessage("Hello World! Struts");      
            return mapping.findForward("success");
    }
}

I have added following code in struts-config file

struts-config.xml:

<form-bean name="HelloWorldForm"
        type="com.redhat.rhn.frontend.common.HelloWorldForm">
</form-bean>


<action path="/extra"
scope="request"
name="HelloWorldForm"
type="com.redhat.rhn.frontend.action.HelloWorldAction">
<forward name="success" path="/WEB-INF/pages/extra.jsp" />
</action>

I get internal server error when I try to access the extra.jsp from browser The intention behind printing hello world is to get to know how to call java method from jsp

The error code 500 is produced via jasper compiler when compiling JSP page that has errors

The tag

<bean:write name="HelloWorldForm" property="message">

isn't closed and compiler will result the error with 500 status code
