    <p>My code look like this:</p> <p>When I try to invoke this method with incorrect url e.g. <a href="http://en.dddddddddssss.org/" rel="nofollow">http://en.dddddddddssss.org/</a> execute throw exception and response is null. Why? How can I got http code in that situation?</p> <pre><code>public Document getDocumentFromUrl(String url) throws SiteBusinessException { Response response = null; try { response = Jsoup.connect(url).timeout(Constans.TIMEOUT).ignoreHttpErrors(false).userAgent(Constans.USER_AGENT) .ignoreContentType(Constans.IGNORE_CONTENT_TYPE).execute(); return response.parse(); } catch (IOException ioe) { LOGGER.warn("Cannot fetch site ]"); return null; } } </code></pre> <p>EDIT</p> <pre><code>public Document getDocumentFromUrl(String url) throws SiteBusinessException { Response response = null; try { response = Jsoup.connect(url).timeout(Constans.TIMEOUT).ignoreHttpErrors(false) .userAgent(Constans.USER_AGENT).ignoreContentType(Constans.IGNORE_CONTENT_TYPE).execute(); return response.parse(); } catch (HttpStatusException hse) { LOGGER.warn("Cannot fetch site [url={}, statusMessage={}, statusCode={}]", new Object[] { url, response != null ? response.statusMessage() : "&lt;null&gt;", response != null ?

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.
