    <p>When I print the contents of <a href="http://www.amazon.com/s/ref=sr_pg_3?rh=n%3A172282&amp;page=1" rel="nofollow">http://www.amazon.com/s/ref=sr_pg_3?rh=n%3A172282&amp;page=1</a>, I see different HTML than what's displayed when utilizing the "View Source" feature in my browser (Chrome, in my case, though I don't think the exact browser matters). For example, the div with id "result_10" from the aforementioned URL appears like this in one's browser:</p> <pre><code>&lt;div id="result_10" class="rsltGrid prod" name="B007I5JT4S"&gt; </code></pre> <p>But when printing the same web page contents with Java's <code>java.net.URL</code> utility, the same div appears like this:</p> <pre><code>&lt;div class="result product" id="result_10" name="B007I5JT4S"&gt; </code></pre> <p>This is just one of the many differences in identifiers and page structure between the HTML produced by programmatically reading this page and using a browser. I'm not sure if this stems from some sort of URL resolution issue or something entirely different.</p> <p>How can I acquire the same page content I see in my browser from a Java app?</p> <p>Here's the function I've been using to read URLs, with "http://www.amazon.com/s/ref=sr_pg_3?rh=n%3A172282&amp;page=1" being the argument in question.</p> <pre><code>public static void printWebPageContents(String url) throws IOException { URL specifiedUrl = new URL(url); BufferedReader in = new BufferedReader(new InputStreamReader(specifiedUrl.openStream())); String inputLine; while ((inputLine = in.readLine()) != null) System.out.println(inputLine); in.close(); } </code></pre> <p>Don't hesitate to let me know if any clarification is needed.</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.
