    <p>I am trying to display a list of cars from my jsp. But i don't understand why nothing appears at the runtime :</p> <p>Servlet code: </p> <pre><code>public class SDisplayCar extends HttpServlet{ private static final long serialVersionUID = 1L; private Gestion gestion = Gestion.getInstance(); protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { int category = Integer.parseInt(request.getParameter("category")); int place = Integer.parseInt(request.getParameter("place")); String startingDate = request.getParameter("dstart"); String endingDate = request.getParameter("dend"); Date start = gestion.getDate(startingDate); Date end = gestion.getDate(endingDate); List&lt;Vehicle&gt; list = gestion.getVehiclesAvailable(category,place,start,end); HttpSession session=request.getSession(); session.setAttribute("list", list); request.getRequestDispatcher("listeOfVehicle.jsp").forward(request,response); } } </code></pre> <p>JSP code:</p> <pre><code>&lt;table border="1"&gt; &lt;thead&gt; &lt;tr&gt; &lt;th&gt;Category&lt;/th&gt; &lt;th&gt;Brand&lt;/th&gt; &lt;th&gt;Model&lt;/th&gt; &lt;th&gt;Places&lt;/th&gt; &lt;/tr&gt; &lt;/thead&gt; &lt;tbody&gt; &lt;c:forEach var="vehicle" items="${list}"&gt; &lt;tr&gt; &lt;td&gt;&lt;c:out value="${vehicle.category}" /&gt;&lt;/td&gt; &lt;td&gt;&lt;c:out value="${vehicle.brand}" /&gt;&lt;/td&gt; &lt;td&gt;&lt;c:out value="${vehicle.model}" /&gt;&lt;/td&gt; &lt;td&gt;&lt;c:out value="${vehicle.places}" /&gt;&lt;/td&gt; &lt;/tr&gt; &lt;/c:forEach&gt; &lt;/tbody&gt; &lt;/table&gt; </code></pre> <p>Am I missing something. I don't get it. When I run the servlet it should display the list of vehicles in the jsp page.</p> <p>I am using hibernate (which works fine and access the database perfectly) and using the MVC model.</p> <p>Here is my form:</p> <pre><code> &lt;body&gt; &lt;Form action="DisplayCar" method="post"&gt; &lt;TABLE BORDER=0&gt; &lt;TR&gt; &lt;TD&gt;Category&lt;/TD&gt; &lt;TD&gt; &lt;SELECT name="category"&gt; &lt;OPTION VALUE="1"&gt;1&lt;/OPTION&gt; &lt;OPTION VALUE="2"&gt;2&lt;/OPTION&gt; &lt;OPTION VALUE="3"&gt;3&lt;/OPTION&gt; &lt;OPTION VALUE="4"&gt;4&lt;/OPTION&gt; &lt;OPTION selected VALUE="5"&gt;5&lt;/OPTION&gt; &lt;/SELECT&gt; &lt;/TD&gt; &lt;/TR&gt; &lt;TR&gt; &lt;TD&gt;Date&lt;/TD&gt; &lt;TD&gt; &lt;P&gt;Starting date: &lt;input type="text" name="dstart" /&gt; &lt;P&gt;End date &lt;input type="text" name="dend" /&gt; &lt;/TD&gt; &lt;/TR&gt; &lt;TR&gt; &lt;TD&gt;Place&lt;/TD&gt; &lt;TD&gt; &lt;SELECT name="place"&gt; &lt;OPTION VALUE="4"&gt;4&lt;/OPTION&gt; &lt;OPTION VALUE="5"&gt;5&lt;/OPTION&gt; &lt;/SELECT&gt; &lt;/TD&gt; &lt;/TR&gt; &lt;TR&gt; &lt;TD COLSPAN=2&gt; &lt;INPUT type="submit" value="Send"&gt; &lt;/TD&gt; &lt;/TR&gt; &lt;/TABLE&gt; &lt;/Form&gt; &lt;/body&gt; &lt;/html&gt; </code></pre>

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
