copied!<p>Disclaimer: I have no idea how the Panda Video Converter works, this is just an example of using <code>RequestBuilder</code> to make GET and POST requests to a server.</p> <p>The steps to accomplish this seem to be roughly:</p> <ol> <li>Send a POST to <code>hq.pandastream.com/videos.(yaml|xml)</code> with your account ID as a parameter.</li> <li>Receive a response including the ID of the new video you've created (a placeholder)</li> <li>Display a form to the user based on the ID. The form is retrieved by sending a GET to <code>upload.pandastream.com/videos/[id]/form</code></li> <li>Submitting this form uploads the video, whose information can be retrieved by sending a GET to <code>GET hq.pandastream.com/videos/id.(yaml|xml)</code></li> </ol> <p>Since the only elements of this process are POST and GET requests, you can use the <a href="http://google-web-toolkit.googlecode.com/svn/javadoc/1.6/com/google/gwt/http/client/RequestBuilder.html" rel="nofollow noreferrer">RequestBuilder</a> to make these requests for you in GWT.</p> <p>We'll go through step by step.</p> <p>Send a POST to <code>hq.pandastream.com/videos.xml</code> with your account ID as a parameter.</p> <pre><code>RequestBuilder rb = new RequestBuilder(RequestBuilder.POST, "http://hq.pandastream.com/videos.xml"); rb.sendRequest("account_key=foo", new RequestCallback() { protected void onResponseReceived(Request request, Response, response) { // parse XML to get "id" element } // onError() ... }); </code></pre> <p>Now that you have the ID, you can make another request to get the upload form HTML.</p> <pre><code>rb = new RequestBuilder(RequestBuilder.GET, "http://upload.pandastream.com/videos/" + id + "/form"); rb.sendRequest(null, new RequestCallback() { protected void onResponseReceived(Request request, Response, response) { // this may not work, and it may be a bad idea to inject third-party HTML // straight into your page. You might also want to open a popup window // instead of injecting the HTML directly. someWidget.setHTML(response.getText()); } // onError() ... }); </code></pre> <p>With that form, the user uploads the video, etc.</p> <p>Now, to get info about the video, it's -- you guessed it -- another <code>RequestBuilder</code> call.</p> <pre><code>rb = new RequestBuilder(RequestBuilder.GET, "http://hq.pandastream.com/videos/" + id + ".xml"); rb.sendRequest(null, new RequestCallback() { protected void onResponseReceived(Request request, Response, response) { // parse response XML to get info you want } // onError() ... }); </code></pre> <p>Another disclaimer: This is a <em>very</em> rough outline of what <em>appears</em> to be the process of uploading a video, based on the docs you linked. This just serves as a basic example of using <code>RequestBuilder</code> to make GET/POST calls.</p>
