    <p>It seems that there are two methods for templating with JSP. Including files with one of these statements </p> <pre><code>&lt;%@ include file="foo.html" %&gt; &lt;jsp:include page="foo.html" /&gt; </code></pre> <p>or using JSP tag files </p> <pre><code>// Save this as mytag.tag &lt;%@ tag description="Description" pageEncoding="UTF-8"%&gt; &lt;html&gt; &lt;head&gt; &lt;/head&gt; &lt;body&gt; &lt;jsp:doBody/&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <p>And in another JSP page call it with</p> <pre><code>&lt;%@ taglib prefix="t" tagdir="/WEB-INF/tags" %&gt; &lt;t:mytag&gt; &lt;h1&gt;Hello World&lt;/h1&gt; &lt;/t:mytag&gt; </code></pre> <p>So which method should I use? Is one now considered deprecated or are they both valid and cover different use cases?</p> <p><strong>Edit</strong></p> <p>Isn't using this tag file the same as using an include?</p> <pre><code>// Save this as product.tag &lt;%@ tag description="Product templage" pageEncoding="UTF-8"%&gt; &lt;%@ tag import="com.myapp.Product" %&gt; &lt;%@ attribute name="product" required="true" type="com.myapp.Product"%&gt; Product name: ${product.name} &lt;br/&gt; Quantity: ${product.quantity} &lt;br/&gt; </code></pre> <p>And call it on another JSP with</p> <pre><code>&lt;%@ taglib prefix="t" tagdir="/WEB-INF/tags" %&gt; &lt;t:product&gt; &lt;c:forEach items="${cart.products}" var="product"&gt; &lt;t:product product="${product}"/&gt; &lt;/c:forEach&gt; &lt;/t:product&gt; </code></pre> <p>That seems to me to be the very same as using an include and passing parameters to it. So are Tag Files the same as includes?</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.
