Hi,
I have prepared test application where after the log in the user can
choose from combo box the country and then the chosen country is added
to arraylist.
Combobox is in html page and business logic and presentation layer are
in JSP.
Now I want to refactor the project in order the business logic to be
included in Serwlet and presentation layer will be in JSP.
I would like to ask you to point me and advise me how to do that in most
professional way.
Bellow I give you the files:
FORM.HTML
<body>
<h3 style='font-size:40px' align='center';>Test Application</h3>
<pre>
<form action="result.jsp" method="get">
<p>First name <input type="text" name="firstName" /></p>
<p>Surname <input type="text" name="surname" /></p>
Male<input type="radio" name="sex" value="male" />
Female<input type="radio" name="sex" value="female" /><br>
Preferable country to live <select name="countryType">
<option value="poland">Poland</option>
<option value="norway" selected>Norway</option>
<option value="hungary">Hungary</option>
<option value="vietnam">Vietnam</option>
<option value="uk">UK</option>
<option value="france">France</option>
</select>
<p><input type="submit" /></p>
</form>
</pre>
</body>
RESULT.JSP
<body>
<h3 style='font-size:40px' align='center';>Test Application</h3>
<%ArrayList arraylist = (ArrayList)session.getAttribute("arraylist");
if(arraylist == null){
arraylist = new ArrayList();
session.setAttribute("arraylist",arraylist);
}
String firstName = request.getParameter("firstName");
String surname = request.getParameter("surname");
String sex = request.getParameter("sex");
String countryType = request.getParameter("countryType");
if(firstName !=null && surname !=null){
Testapplication.Person person1 = new Testapplication.Person();
person1.setFirstName(firstName);
person1.setSurname(surname);
person1.setSex(sex);
person1.setCountryType(countryType);
//The object person1 is added to arraylist
arraylist.add(person1);
}
out.println("The list contains " +arraylist.size()+ " persons");
%>
<div class="results">
<table border="1"; style="height: 40px;width: 500px; background:white;" >
<tr><th colspan="5"><strong>Results:</strong></th></tr>
<tr>
<td><strong>First name</strong></td>
<td><strong>Surname</strong></td>
<td><strong>Sex</strong></td>
<td><strong>Country</strong></td>
</tr>
<%/*ListIterator it = arraylist.listIterator();
while (it.hasNext()){
Person person =(Person)it.next();*/%>
<% for (Iterator it = arraylist.iterator(); it.hasNext();){
Person person =(Person)it.next();%>
<tr>
<td>
<% out.println(person.getFirstName());%>
</td>
<td>
<%out.println(person.getSurname());%>
</td>
<td>
<%out.println(person.getSex());%>
</td>
<td>
<%out.println(person.countryType());%>
</td>
</tr>
<%}%>
</table>
<br/><input type=button value="Add new
record"onClick="document.location='form.html'">
</div>
</body>
