    text
    copied!<p>I have a URLConnection, that access a web page.</p> <pre><code>URL url = new URL("https://domain"); con = url.openConnection(); con.setDoOutput(true); </code></pre> <p>Then i sent some data to the server using <code>con.setRequestProperty()</code></p> <p>I get the response cookies fro ma specified field using </p> <pre><code>String headerValue = con.getHeaderField(6); </code></pre> <p>I also get the html and parse an image url from there. But here is a problem. I can get this image only by sending cache data back to the server ,when i acces my image.</p> <p>So i open a new connection</p> <pre><code>URL url1 = new URL("https://domain/image); URLConnection con1 = url1.openConnection(); </code></pre> <p>I send the cookies back to the server <code>con1.setRequestProperty("Cookie", headerValue);</code></p> <p>And finally i try to acces the image using BufferedInputStream and then creating an iamge in a JLabel</p> <pre><code>BufferedInputStream in = new BufferedInputStream(con1.getInputStream()); ByteArrayOutputStream byteArrayOut = new ByteArrayOutputStream(); int c; while ((c = in.read()) != -1) { byteArrayOut.write(c); } Image image = Toolkit.getDefaultToolkit().createImage( byteArrayOut.toByteArray()); label.setIcon(new ImageIcon(image)); </code></pre> <p>The problem is this seems to not work. Is it another way to get an file from a server through a URlConnection? Error code</p> <pre><code>Server returned HTTP response code: 400 for URL: https://domain/image at sun.net.www.protocol.http.HttpURLConnection.getInputStream(Unknown Source) at sun.net.www.protocol.https.HttpsURLConnectionImpl.getInputStream(Unknown Source) </code></pre> <p>Thanks in advance</p>
