You need to enhance the Exotica Web application in such a ray that when the Inquire Nov/ hyperlink is clicked, the Inquire Nov/ Web page gets displayed. Therefore, you need to develop the Inquire Nov/ Web page, as shown in the following figure.
In addition, you need to perform the following validations when the form is submitted:
• The values, such as name, address, contact number or email ID. and query, are filled by the user.
• If the user has selected the option. Respond via phone, the contact number field must have a value: and if the user has selected the option. Respond via email, the email field must have a value.
• If the respond via phone option is selected, you also need to ensure that the date and time is selected.
Further, if the user has submitted the form with appropriate values, the message. Thank you. Our executive will get back to you soon, should be displayed.
1. Open the Web application. ExoticaTravel.
2. Create the JSP page. InquireNowPage.jsp. and replace the cede with the following code:
<%@ taglib prefix="c"
uri="http://java.sun.com/jap/jstl/core" %>
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html charset=UTF-8">
<title>JSP Page</title>

<body>
<c:if test="S(not empty errorMessage)">
<P>
<£ont color="red">Please correct the following errors:
<ul>
<c:forEach var="message" items="${errorMessage}">

</c:forEach>
</ul>
</font>
</p>
</c:if>
<form action="InquireNowServlet">

3. Create a servlet. InquireNowServletjava. and replace the existing code with the following code:
import java.io.IOException; import java.io.PrintWriter; import java.util.ArrayList; import javax.servlet.RequestDispatcher; import javax.servlet.ServletException; import javax.servlet.annotation.WebServlet; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse;

responseTypeEmailVal — "unchecked", day, month, year, time; ArrayList errorMessage = new ArrayList();

throws ServletException, IOException { response.setContentType("text/html;charset=UTF-8"); PrintWriter out = response.getWriter();
try {
errorMessage.clear();

day = request.getParameter("day"); month = request.getParameter("month"); year = request.getParameter("year"); time = request.getParameter("time");
if (errorMessage.isEmpty()) {
iNarae = request.getParameter("iNamc");
if (iName.equals("")) {
errorMessage.add("Please enter your

}
if (query.equals("")) {
errorMessage.add("Please specify your

)
if (phone.equals("") && email-equals("")) { errorMessage.add("Please enter the contact number or email ID");

if(!phone.equals("")){
if (!(phone.matches("-?\\d+(\\.\\d

errorMessage.add("Please enter a

if (responseType == null) {
errorMessage.add("Please select the

} else {

responseTypcEmailVal =

if (day.equals("select") ||
month.equals("select") || year.equals("select") || time.equals("select")) {
errorMessage.add

}
}
}
}
else { if

}
(email.equals("") ) { errorMessage.add("Please enter

}
if (! errorMessage. isEmptyO ) {
request.setAttribute("iName", iName); request.setAttribute("address",
address);
request.setAttribute (••query", query) ; request.setAttribute("phone", phone); request.setAttribute("email", email); request.setAttribute
("responseTypePhone", responseTypePhoneVal);
request.setAttribute

request -setAttribute("errorMessage",
errorMessage);
RequestDispatcher rd =
request.getRequcstDispetcher("InquireNowPage.jsp");
rd.forward(request, response);
> (
System.out.println ("InquireNowDisplayPagc.jsp");
RequestDispatcher rd =
request.getRequestDispatcher("InquireNowDisplayPage.j sp");
rd.forward(request, response);
}
}
catch (Exception e) {
System.out.println(e);
} finally {
out.close();
}
}
