copied!<p>I'm trying to connect to the internet via my J2ME application on my Netbeans emulator with the following function which connects to a webpage and prints out its HTML using <code>System.out.println()</code>.</p> <pre><code>function getHTML(String url) { HttpConnection httpConn = null; InputStream is = null; OutputStream os = null; try { httpConn = (HttpConnection)Connector.open(url); int respCode = httpConn.getResponseCode(); if (respCode == httpConn.HTTP_OK) { StringBuffer sb = new StringBuffer(); os = httpConn.openOutputStream(); is = httpConn.openDataInputStream(); int chr; while ((chr = is.read()) != -1) sb.append((char) chr); System.out.println(sb.toString()); os.close(); is.close(); } else { System.out.println("Error " + respCode); } httpConn.close(); } catch(IOException ioex) { ioex.printStackTrace(); } } </code></pre> <p>But I've been getting the following error;</p> <pre><code>javax.microedition.io.ConnectionNotFoundException: error 10051 in socket::open at com.sun.midp.io.j2me.socket.Protocol.open0(), bci=0 at com.sun.midp.io.j2me.socket.Protocol.connect(), bci=209 at com.sun.midp.io.j2me.socket.Protocol.open(), bci=216 at com.sun.midp.io.j2me.socket.Protocol.openPrim(), bci=4 at com.sun.midp.io.j2me.http.Protocol.createConnection(), bci=41 at com.sun.midp.io.j2me.http.Protocol.connect(), bci=41 at com.sun.midp.io.j2me.http.Protocol.streamConnect(), bci=164 at com.sun.midp.io.j2me.http.Protocol.startRequest(), bci=7 at com.sun.midp.io.j2me.http.Protocol.sendRequest(), bci=33 at com.sun.midp.io.j2me.http.Protocol.sendRequest(), bci=3 at com.sun.midp.io.j2me.http.Protocol.getResponseCode(), bci=5 </code></pre> <p>I know my code isn't the problem because this used to work on my old laptop, but it hasn't worked since I installed Netbeans on my new laptop. Is it because of my internet connection, or my firewall settings, or my settings in Netbeans, or did I just not install Netbeans properly?</p>
