    <p>I'm trying to retrieve a table from a database and populating it in a table. The table will be editable by using EditableGrid (<a href="http://www.editablegrid.net/en" rel="nofollow">http://www.editablegrid.net/en</a>). I'm populating the tables automatically like so:</p> <h1>Report Results</h1> <pre><code>&lt;table id="htmlgrid" border="1"&gt; &lt;!-- column headers --&gt; &lt;tr&gt; &lt;c:forEach var="columnName" items="${result.columnNames}"&gt; &lt;th&gt;&lt;c:out value="${columnName}" /&gt;&lt;/th&gt; &lt;/c:forEach&gt; &lt;/tr&gt; &lt;!-- column data --&gt; &lt;c:forEach var="row" items="${result.rowsByIndex}"&gt; &lt;tr&gt; &lt;c:forEach var="column" items="${row}"&gt; &lt;td&gt;&lt;c:out value="${column}" /&gt;&lt;/td&gt; &lt;/c:forEach&gt; &lt;/tr&gt; &lt;/c:forEach&gt; &lt;/table&gt; </code></pre> <p>The result is retrieved like so:</p> <pre><code>c = ConnectionManager.getConnection(); ps = c.prepareStatement("select * from test_persons", ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_READ_ONLY); rs = ps.executeQuery(); Result result = ResultSupport.toResult(rs); request.setAttribute("result", result); RequestDispatcher rd = request .getRequestDispatcher("/display.jsp"); rd.forward(request, response); </code></pre> <p>The thing is, in order to use EditableGrid, the tr tags need an id, for example:</p> <pre><code> &lt;tr id="R1"&gt; &lt;td&gt;Duke&lt;/td&gt; &lt;td&gt;Patience&lt;/td&gt; &lt;td&gt;33&lt;/td&gt; &lt;td&gt;1.842&lt;/td&gt; &lt;td&gt;uk&lt;/td&gt; &lt;td&gt;patience.duke@gmail.com&lt;/td&gt; &lt;td&gt;false&lt;/td&gt; &lt;td&gt;11/12/2002&lt;/td&gt; &lt;/tr&gt; &lt;tr id="R2"&gt; &lt;td&gt;Rogers&lt;/td&gt; &lt;td&gt;Denise&lt;/td&gt; &lt;td&gt;59&lt;/td&gt; &lt;td&gt;1.627&lt;/td&gt; &lt;td&gt;us&lt;/td&gt; &lt;td&gt;rogers.d@gmail.com&lt;/td&gt; &lt;td&gt;&lt;/td&gt; &lt;td&gt;07/05/2003&lt;/td&gt; &lt;/tr&gt; </code></pre> <p>How would I use the jstl to automatically put in the tags in? The database may return any number of rows depending on the query. Is this possible? Or is there a better solution to populate a table from a resultset and make it editable (for the purposes of updating the database later on).</p>

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.
