    copied!<p>I have the following class that I'm using in my Java with JSP applicaton.</p> <p>// public class QuestionBO implements Serializable{</p> <pre><code>private int questionId; private int testID; private String question; private TutorBO infoAboutTutor; private SubjectBO infoAboutSubject; private TestBO infoAboutTest; private List&lt;AnswerBO&gt; answers; public QuestionBO() { } public QuestionBO(String question) { this.question = question; } </code></pre> <p>getter &amp; setter....</p> <p>The JSP page has a form where each Question (its String representation) has a checkbox next to it. A user marks some of the questions and submits the form to the server for processing by a servlet.</p> <p>What is the conventional way of binding the Question objects with the checkboxes so that I could find out what Questions have been selected?</p> <p>Currently I'm using the following approach for constructing the form:</p> <p>// </p> <pre><code> &lt;c:if test="${not empty questionsForSubject}"&gt; &lt;form action="/TutorWebApp/controller" method="POST" name="addQuestionForm"&gt; &lt;input type="hidden" name="command" value="add_question_list" /&gt; &lt;input type="hidden" name="testName" value="${testName}"/&gt; &lt;table border ="1"&gt; &lt;tbody&gt; &lt;c:forEach items="${questionsForSubject}" var="question"&gt; &lt;tr&gt; &lt;td&gt; &lt;input type="checkbox" name ="choosen_question" value="${question.getQuestion()}"&gt; ${question.getQuestion()} &lt;br /&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/c:forEach&gt; &lt;/tbody&gt; &lt;/table&gt; &lt;input type="submit" value="Add questions "/&gt; &lt;/form&gt; </code></pre> <p>And I shouldn't use frameworks.</p> <p>Thanks</p> <p>And I have last question </p> <pre><code> &lt;c:if test="${not empty questionsForSubject}"&gt; &lt;form action="/TutorWebApp/controller" method="POST" name="addQuestionForm"&gt; &lt;input type="hidden" name="command" value="add_question_list" /&gt; &lt;input type="hidden" name="testName" value="${testName}"/&gt; &lt;input type="hidden" name="questionsForSubject" value="${questionsForSubject}"/&gt; &lt;table border ="1"&gt; &lt;tbody&gt; &lt;c:forEach items="${questionsForSubject.keySet()}" var="questionID"&gt; &lt;tr&gt; &lt;td&gt; &lt;input type="checkbox" name ="choosen_question" value="${questionID}"&gt; ${questionsForSubject.get(questionID).getQuestion()} &lt;br /&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/c:forEach&gt; &lt;/tbody&gt; &lt;/table&gt; &lt;input type="submit" value="Добавить вопросы"/&gt; &lt;/form&gt; </code></pre> <p>How I can get map from this page on servlet?</p>
