  1. PO403 error while fetching content from URL
    text
    copied!<p>I am trying to automate a process. For that I need to fetch XML by hitting a URL, multiple times in 1 run, and then parse it. For 1 run of the program, the URL could be hit anywhere between 4 to 25 times. This all seems fine until a 403 error response is returned.</p> <p>Interestingly, the 403 always comes up for every 5th or 6th time the URL is hit.</p> <p>I am using JDOM to parse the XML response.</p> <p>I have tried the codes:</p> <pre><code>Document doc = builder.build(new InputSource(url.openStream())); </code></pre> <p>and </p> <pre><code>HttpURLConnection conn = (HttpURLConnection)url.openConnection(); conn.setRequestProperty("User-Agent", "Mozilla/5.0 (Windows; U; Windows NT 6.1; en-GB; rv:1.9.2.13) Gecko/20101203 Firefox/3.6.13 (.NET CLR 3.5.30729)"); Document doc = builder.build(conn.getInputStream()); </code></pre> <p>With the second one I get the Exception:</p> <pre><code>org.jdom.input.JDOMParseException: Error on line 1: White spaces are required between publicId and systemId. </code></pre> <p>Could someone please help me in getting rid of the 403. Please note that I do not have any control over the source if a change is required to be made as talked about <a href="http://www.sugarcrm.com/forums/f6/white-spaces-required-between-publicid-systemid-12367/" rel="nofollow noreferrer">here</a></p> <p>Also, I am not sure if <a href="https://stackoverflow.com/questions/4633048/httpurlconnection-reading-response-content-on-403-error">this link</a> is helpful.</p> <p>Thank you.</p> <p><hr/> [UPDATE 1]: This is somehow working, without having to <code>sleep</code>: </p> <pre><code>try{ doc = builder.build(conn.getInputStream()); }catch(IOException ioEx){ doc = builder.build(new InputSource(url.openStream())); } </code></pre>
