    Default how to delete record from checking checkbox value.

    i would like to use jsp and java to write a add/edit/delete function.

    I am a beginner, now i dont know how to create a java as a database layer in which i connect to database and write sql statement to insert/delete/update the table.

    afterwards, i would like to use jsp to create a layout.

    now , I don't know how to check the checkbox value from the table and then the user click the delete button to delete all ticked record in the table.

    I already write the code in jsp as belows:
    <INPUT TYPE="submit" value="Delete" onClick="">
    while(rs.next())
        {
         %>
         <tr><td><%=rs.getString(1) %></td>
         <td><%=rs.getString(2) %></td>
         <td><%=rs.getString(3) %></td>
         <td><center><input type="checkbox" name="del" ></center></td></tr>

    To use java to access the database, first please read about the JDBC apis.
    and then learn how to use javascript to access DOM objects

    Cheers

    If your page has a control something like this:

    <input type="checkbox" name="idValue" value="${myObj.id}">


    Then in the servlet that you go to when submitting the form:
    String[] idsToDelete = request.getParameterValues("idValue");
    That will give you an array of all the ids that were selected that need to be deleted.
    Loop through that array, and delete them one by one.
