    <p>Just pass the unique identifier of the book as request parameter or request path info and have a <a href="https://stackoverflow.com/tags/servlets/info">servlet</a> to perform the data lookup in the <code>doGet()</code> method based on the identifier, store it in the request scope and forward to a JSP file which generates all the necessary HTML.</p> <p>E.g. as request parameter <code>/book?id=123</code> with this servlet</p> <pre><code>@WebServlet("/book") public class BookServlet extends HttpServlet { @EJB private BookService service; @Override protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { Book book = service.find(request.getParameter("id")); request.setAttribute("book", book); request.getRequestDispatcher("/WEB-INF/book.jsp").forward(request, response); } } </code></pre> <p>Or as request path info <code>/book/123</code> with this servlet</p> <pre><code>@WebServlet("/book/*") public class BookServlet extends HttpServlet { @EJB private BookService service; @Override protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { Book book = service.find(request.getPathInfo().substring(1)); request.setAttribute("book", book); request.getRequestDispatcher("/WEB-INF/book.jsp").forward(request, response); } } </code></pre> <p>Either way, the <code>/WEB-INF/book.jsp</code> could just look like this the usual way.</p> <pre><code>&lt;p&gt;Title: &lt;c:out value="${book.title}" /&gt;&lt;/p&gt; &lt;p&gt;Author: &lt;c:out value="${book.author}" /&gt;&lt;/p&gt; &lt;p&gt;Summary: &lt;c:out value="${book.summary}" /&gt;&lt;/p&gt; </code></pre> <p>In order to generate those links to the servlet, just loop over a <code>List&lt;Book&gt;</code> in <code>/WEB-INF/books.jsp</code> as follows, assuming that you want URLs like <code>/book/123</code>: </p> <pre><code>&lt;ul&gt; &lt;c:forEach items="${books}" var="book"&gt; &lt;li&gt; &lt;a href="${pageContext.request.contextPath}/book/${book.id}"&gt; View book with title: &lt;c:out value="${book.title}" /&gt; &lt;/a&gt; &lt;/li&gt; &lt;/c:forEach&gt; &lt;/ul&gt; </code></pre>

    2. COThat's just a loop over `List<Book>`. It's like `for (Book book : books) {}` in normal Java code. Click the "servlet" link in my answer for more examples.

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).
