this EmployeeBean is only for 1 row table, but i want to make that for five rows that to I wanted to know how to create multiple EmployeeBean Objects. please help...
Thnaks!


can you try this,
<%! int TOTAL_NUMBER_OF_ROW = 10; %>
<form action="TimeSheet" method="post">
<fieldset style="width: 90%">
<legend>Timesheet</legend>
<h2>Time Sheet application</h2>

how to set each row to pass its values to servlet - whatever input I click, I have always first row

Why I can only count value for first row, though Jsp displays every row with correct values.
It always pass first row of data to the Servlet. If I choose first row it works, but if I choose any other it takes values of first row and program collapse due to empty string.
#Override
protected void doPost(HttpServletRequest request,
HttpServletResponse response) throws
ServletException, IOException {
PrintWriter printWriter = response.getWriter();
String currency = request.getParameter("currency");
int id = Integer.parseInt(request.getParameter("id"));
float rates = Float.parseFloat(request.getParameter("rates"));
float amount =
Float.parseFloat(request.getParameter("amount"));;
float euro = amount * rates;
printWriter.append(String.valueOf(id)).append(" : ");
printWriter.append(currency).append(" - ");
printWriter.append("rate : ").append(String.valueOf(rates));
printWriter.append(" ---> You have got
").append(String.valueOf(euro)).append("
Euros");
}
<form action="/exchangeServlet" method="post">
<table border="1">
<tr>
<th>Currency</th>
<th>Rate</th>
<th>Amount</th>
<th>Action</th>

<c:forEach var="tempValue" items="${kalkulatorList}"

Thymeleaf Map Form Binding

db.html
<div th:each="pr, stat: *{mergeMap}">
<tr>
<td><input type="text" name="key" th:value="${pr.key}" /></td>
<td><input type="text" name="value" th:value="${pr.value}" /></td>
</tr>
</div>
On submitting this input, i always get mergeMap to be empty at the Spring Controller. What should be done to get the value of mergeMap?
Controller.java
#RequestMapping(value = "/shot")
public String saveMergeProducts(#ModelAttribute(value="prod") MergedProductInfoDTO prod, BindingResult bindingResult,
Model model, HttpServletRequest request) {
System.out.println(prod.toString());
return "forward:/backoffice/db";
}
HTML
<form action="#" th:action="#{shot}" method="POST" th:object="${prod}">
<tr>
<td><span th:text="${index.index}"></span></td>
<td><input type="text" name="id" th:value="*{id}" th:readonly="readonly" /></td>
<td><input type="text" name="categoryName" th:value="*{categoryName}" th:readonly="readonly" /></td>
<td><input type="text" name="subCategoryName" th:value="*{subCategoryName}" th:readonly="readonly" /></td>
<td><input type="text" name="productBrand" th:value="*{productBrand}" /></td>
<td><input type="text" name="productSubBrand" th:value="*{productSubBrand}" /></td>
<td><input type="text" name="series" th:value="*{series}" /></td>
<td><input type="text" name="model" th:value="*{model}" /></td>
</tr>
<tr>
<td colspan="7">
<tr>
<th>KEY</th>
<th>VALUE</th>
</tr>
<div th:each="pr, stat: *{mergeMap}">
<tr>
<td><input type="text" name="mergeMapKey" th:value="${pr.key}" /></td>
<td><input type="text" name="mergeMapValue" th:value="${pr.value}" /></td>
</tr>
</div>
</table>
</td>
<td><input type="text" name="tags" th:value="*{tags}" /></td>
<td><input type="submit" value="Submit" /></td>
</tr>

To access the Map property of the form-backing bean, use the __${...}__ preprocessor
<div th:each="pr, stat: *{mergeMap}">
<tr>
<td><input type="text" name="value" th:value="${pr.key}" readonly="true"/></td>
<td><input type="text" name="value" th:field="*{mergeMap[__${pr.key}__]}"/></td>
</tr>
</div>
What it does it evaluates the inner expression first before evaluating the whole expression. Note that in this case, ${pr.key} should not be modified so that the update will be reflected to the map property of the bean bound to the form.

I dont know how to make employeebean to list type... pelase check the Timesheetservlet and timesheetdao.
please help me to insert 5 rows in database.
thanks!

I have changed your jsp to have different names for the different rows.
and also changed the serverlet code to read and build the list of employee bean.
once you do these changes you can use the logic mentioned by the chrisI08 abovve.
timesheet.jsp.

Note: I have not compiled this code.you may need to change few things.

You need to use batch inserts: http://viralpatel.net/blogs/batch-insert-in-java-jdbc/ Look at "SQL Injection Safe Batch" section. I have modified the TimeSheetDao.insert method as below:
import java.sql.Connection;
import java.sql.PreparedStatement;
public class TimeSheetDao {
// this sql string can be static final
public static final String sql= "insert into logintable values(?,?,?,?,?,?,?,?,?,?)";
public static int insert(List<EmployeeBean> employees) throws Exception {
Connection connection = new getConnection();
PreparedStatement ps = connection.prepareStatement(sql);
try {
for (EmployeeBean employee: employees) {
// set parameters here
ps.setDate(2,new Date(eb.getLogindate().getTime()));
ps.setString(3,eb.getLogintime());
ps.setString(4,eb.getLogouttime());
ps.setString(5,eb.getLunch());
ps.setString(6,eb.getAfterlunchlogin());
ps.setString(7,eb.getAfterlunchlogout());
ps.setString(8,eb.getTask());
ps.setString(9,eb.getTotal());
ps.setString(10,eb.getOvertime());
ps.addBatch();
}
ps.executeBatch();
} finally {
ps.close();
connection.close();
}
}

Whenever I try to insert data using jsp form, it keeps executing nullPointerException as my cust_id is not auto generated or auto increment.
After I click addbutton, servlet sent to updateUser and data cannot be inserted.
Customer customer = new Customer();
customer.setCustName(request.getParameter("custName"));
customer.setCustAdd(request.getParameter("custAdd"));
customer.setCustRegion(request.getParameter("custRegion"));
customer.setCustHandphoneNo(request.getParameter("custHandphoneNo"));
customer.setCustPhoneNo(request.getParameter("custPhoneNo"));

if(cust_id == null || cust_id.isEmpty())

dao.addUser(customer);
}
else

customer.setCust_id(cust_id);
dao.updateUser(customer);
}
RequestDispatcher view = request.getRequestDispatcher(LIST_USER);
request.setAttribute("customer", dao.getAllCustomer());

help me out..

You should never use the same ID on two elements!
It's better to use class instead. The id-attribute is reserved for unique idintifiers
