• parsing xml using dom4j

  - by D3GAN

  My XML structure is like this: <rss> <channel> <yweather:location city="Paris" region="" country="France"/> <yweather:units temperature="C" distance="km" pressure="mb" speed="km/h"/> <yweather:wind chill="-1" direction="40" speed="11.27"/> <yweather:atmosphere humidity="87" visibility="9.99" pressure="1015.92" rising="0"/> <yweather:astronomy sunrise="8:30 am" sunset="4:54 pm"/> </channel> </rss> when I tried to parse it using dom4j SAXReader xmlReader = createXmlReader(); Document doc = null; doc = xmlReader.read( inputStream );//inputStream is input of function log.info(doc.valueOf("/rss/channel/yweather:location/@city")); private SAXReader createXmlReader() { Map<String,String> uris = new HashMap<String,String>(); uris.put( "yweather", "http://xml.weather.yahoo.com/ns/rss/1.0" ); uris.put( "geo", "http://www.w3.org/2003/01/geo/wgs84_pos#" ); DocumentFactory factory = new DocumentFactory(); factory.setXPathNamespaceURIs( uris ); SAXReader xmlReader = new SAXReader(); xmlReader.setDocumentFactory( factory ); return xmlReader; } But I got nothing in cmd but when I print doc.asXML(), my XML structure print correctly!

• Need help with strange Class#getResource() issue

  - by Andreas_D

  I have some legacy code that reads a configuration file from an existing jar, like: URL url = SomeClass.class.getResource("/configuration.properties"); // some more code here using url variable InputStream in = url.openStream(); Obviously it worked before but when I execute this code, the URL is valid but I get an IOException on the third line, saying it can't find the file. The url is something like "file:jar:c:/path/to/jar/somejar.jar!configuration.properties" so it doesn't look like a classpath issue - java knows pretty well where the file can be found.. The above code is part of an ant task and it fails while the task is executed. Strange enough - I copied the code and the jar file into a separate class and it works as expected, the properties file is readable. At some point I changed the code of the ant task to URL url = SomeClass.class.getResource("/configuration.properties"); // some more code here using url variable InputStream in = SomeClass.class.getResourceAsStream("/configuration.properties"); and now it works - just until it crashes in another class where a similiar access pattern is implemented.. Why could it have worked before, why does it fail now? The only difference I see at the moment is, that the old build was done with java 1.4 while I'm trying it with Java 6 now. Workaround Today I installed Java 1.4.2_19 on the build server and made ant to use it. To my totally frustrating surprise: The problem is gone. It looks to me, that java 1.4.2 can handle URLs of this type while Java 1.6 can't (at least in my context/environment). I'm still hoping for an explanation although I'm facing the work to rewrite parts of the code to use Class#getRessourceAsStream which behaved much more stable...

• Just need someone familiar with HTTPClient to check over a piece of code

  - by jax

  here are two little helper methods I have made for downloading files. I have had to mix and match different tutorials of the web to get what I have here. Now is there anything that I have done blatantly wrong here? public static InputStream simplePostRequest(URL url, List<NameValuePair> postData) throws ClientProtocolException, IOException { DefaultHttpClient httpclient = new DefaultHttpClient(); HttpPost postMethod=new HttpPost(url.toExternalForm()); postMethod.setEntity(new UrlEncodedFormEntity(postData, HTTP.UTF_8)); HttpResponse response = httpclient.execute(postMethod); HttpEntity entity = response.getEntity(); return entity.getContent(); } public static InputStream simpleGetRequest(URL url, List<NameValuePair> queryString) throws ClientProtocolException, IOException { Uri.Builder uri = new Uri.Builder(); uri.path(url.getPath()); for(NameValuePair nvp: queryString) { uri.appendQueryParameter(nvp.getName(), nvp.getValue()); } DefaultHttpClient httpClient = new DefaultHttpClient(); HttpHost host = new HttpHost(url.getHost()); HttpResponse response = httpClient.execute(host, new HttpGet(uri.build().toString())); HttpEntity entity = response.getEntity(); return entity.getContent(); }

• .net Drawing.Graphics.FromImage() returns blank black image

  - by joox

  I'm trying to rescale uploaded jpeg in asp.net So I go: Image original = Image.FromStream(myPostedFile.InputStream); int w=original.Width, h=original.Height; using(Graphics g = Graphics.FromImage(original)) { g.ScaleTransform(0.5f, 0.5f); ... // e.g. using (Bitmap done = new Bitmap(w, h, g)) { done.Save( Server.MapPath(saveas), ImageFormat.Jpeg ); //saves blank black, though with correct width and height } } this saves a virgin black jpeg whatever file i give it. Though if i take input image stream immediately into done bitmap, it does recompress and save it fine, like: Image original = Image.FromStream(myPostedFile.InputStream); using (Bitmap done = new Bitmap(original)) { done.Save( Server.MapPath(saveas), ImageFormat.Jpeg ); } Do i have to make some magic with g? upd: i tried: Image original = Image.FromStream(fstream); int w=original.Width, h=original.Height; using(Bitmap b = new Bitmap(original)) //also tried new Bitmap(w,h) using (Graphics g = Graphics.FromImage(b)) { g.DrawImage(original, 0, 0, w, h); //also tried g.DrawImage(b, 0, 0, w, h) using (Bitmap done = new Bitmap(w, h, g)) { done.Save( Server.MapPath(saveas), ImageFormat.Jpeg ); } } same story - pure black of correct dimensions

• Android: Gzip/Http supported by default?

  - by OneWorld

  I am using the code shown below to get Data from our server where Gzip is turned on. Does my Code already support Gzip (maybe this is already done by android and not by my java program) or do I have to add/change smth.? How can I check that it's using Gzip? For my opionion the download is kinda slow. private static InputStream OpenHttpConnection(String urlString) throws IOException { InputStream in = null; int response = -1; URL url = new URL(urlString); URLConnection conn = url.openConnection(); if (!(conn instanceof HttpURLConnection)) throw new IOException("Not an HTTP connection"); try { HttpURLConnection httpConn = (HttpURLConnection) conn; httpConn.setAllowUserInteraction(false); httpConn.setInstanceFollowRedirects(true); httpConn.setRequestMethod("GET"); httpConn.connect(); response = httpConn.getResponseCode(); if (response == HttpURLConnection.HTTP_OK) { in = httpConn.getInputStream(); if(in == null) throw new IOException("No data"); } } catch (Exception ex) { throw new IOException("Error connecting"); } return in; }

• Accessing to Request object will lead to ReadEntityBody to return 0 (in a HttpHandler class)

  - by EBAG

  I created a httpHandler that successfully implements IHttpHandler for handling file uploads. It works perfectly fine. You send the file with the form, the class receives it and will save it to hard disk. It reads chunks of file with ReadEntityBody function of HttpWorkerRequest class. Here is the situation i'm faced with.If at any stage before trying to read the file with ReadEntityBody, I try to access Request object (even Request.InputStream.Length!) ReadEntityBody would return 0 means it won't read from file stream. After further testing I found out the reason behind it. Accessing to Context.Current.Request object will trigger some sort of functionality that will cause asp.net to handle file uploads at that moment by it's own! I believe this is a bug. for example exactly after this line of code, asp.net will upload the file completely, and so there will be no stream for ReadEntityBody to read from later. int FileSize = context.Request.InputStream.Length; Can anybody tell how to stop this?

• How to ensure I get the picture is complete? (in java)

  - by Zenofo

  i using below code to get a picture from URL: URL url=new URL("http://www.google.com/images/logos/ps_logo2.png"); InputStream in=url.openStream(); ByteArrayOutputStream tmpOut = new ByteArrayOutputStream(); byte[] buf = new byte[512]; int len; while (true) { len = in.read(buf); if (len == -1) { break; } tmpOut.write(buf, 0, len); } tmpOut.close(); byte[] picture=tmpOut.toByteArray(); System.out.println(picture.length); this code is okay,but my internet connect is very very bad, so ,I maybe get a broken picture like this: How can I ensure the picture file is complete ? I think you can add this code to try and test this: if (len == -1) { change to if (len == -1 || (int)(Math.random()*100)==1 ) { full test code: URL url=new URL("http://www.google.com/images/logos/ps_logo2.png"); InputStream in=url.openStream(); ByteArrayOutputStream tmpOut = new ByteArrayOutputStream(); byte[] buf = new byte[512]; int len; while (true) { len = in.read(buf); if (len == -1 || (int)(Math.random()*100)==1 ) { break; } tmpOut.write(buf, 0, len); } tmpOut.close(); byte[] picture =tmpOut.toByteArray(); System.out.println(picture.length); thanks for help :)

• Playing repeated sound in Java

  - by Diogo Schneider

  I'm trying to play sounds in a Java game with the following code: AudioStream audioStream = new AudioStream(stream); AudioPlayer.player.start(audioStream); The stream variable is just an InputStream to the resource. By the first time this code is called, the sound is played as expected, but by the second time the program just hangs, not even an exception is thrown. I don't know what's going on or how to prevent this. If I try closing either stream or audioStream after the above code, the program doesn't hang, but no sound is ever played at all. Any tips are welcome, thanks.

• How do I put different textures on different walls? LWJGL

  - by lehermj

  So far I have it so you are running around in a box, but all of the walls are the same texture! I've loaded up other textures for the walls (I want the walls a different texture than the floor) but it seems as if its being ignored... Here's my code: int floorTexture = glGenTextures(); { InputStream in = null; try { in = new FileInputStream("floor.png"); PNGDecoder decoder = new PNGDecoder(in); ByteBuffer buffer = BufferUtils.createByteBuffer(4 * decoder.getWidth() * decoder.getHeight()); decoder.decode(buffer, decoder.getWidth() * 4, Format.RGBA); buffer.flip(); glBindTexture(GL_TEXTURE_2D, floorTexture); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST); glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, decoder.getWidth(), decoder.getHeight(), 0, GL_RGBA, GL_UNSIGNED_BYTE, buffer); glBindTexture(GL_TEXTURE_2D, floorTexture); } catch (FileNotFoundException ex) { System.err.println("Failed to find the texture files."); ex.printStackTrace(); Display.destroy(); System.exit(1); } catch (IOException ex) { System.err.println("Failed to load the texture files."); ex.printStackTrace(); Display.destroy(); System.exit(1); } finally { if (in != null) { try { in.close(); } catch (IOException e) { e.printStackTrace(); } } } } int wallTexture = glGenTextures(); { InputStream in = null; try { in = new FileInputStream("walls.png"); PNGDecoder decoder = new PNGDecoder(in); ByteBuffer buffer = BufferUtils.createByteBuffer(4 * decoder.getWidth() * decoder.getHeight()); decoder.decode(buffer, decoder.getWidth() * 4, Format.RGBA); buffer.flip(); glBindTexture(GL_TEXTURE_2D, wallTexture); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST); glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, decoder.getWidth(), decoder.getHeight(), 0, GL_RGBA, GL_UNSIGNED_BYTE, buffer); glBindTexture(GL_TEXTURE_2D, wallTexture); } catch (FileNotFoundException ex) { System.err.println("Failed to find the texture files."); ex.printStackTrace(); Display.destroy(); System.exit(1); } catch (IOException ex) { System.err.println("Failed to load the texture files."); ex.printStackTrace(); Display.destroy(); System.exit(1); } finally { if (in != null) { try { in.close(); } catch (IOException e) { e.printStackTrace(); } } } } int ceilingDisplayList = glGenLists(1); glNewList(ceilingDisplayList, GL_COMPILE); glBegin(GL_QUADS); glTexCoord2f(0, 0); glVertex3f(-gridSize, ceilingHeight, -gridSize); glTexCoord2f(gridSize * 10 * tileSize, 0); glVertex3f(gridSize, ceilingHeight, -gridSize); glTexCoord2f(gridSize * 10 * tileSize, gridSize * 10 * tileSize); glVertex3f(gridSize, ceilingHeight, gridSize); glTexCoord2f(0, gridSize * 10 * tileSize); glVertex3f(-gridSize, ceilingHeight, gridSize); glEnd(); glEndList(); int wallDisplayList = glGenLists(1); glNewList(wallDisplayList, GL_COMPILE); glBegin(GL_QUADS); // North wall glTexCoord2f(0, 0); glVertex3f(-gridSize, floorHeight, -gridSize); glTexCoord2f(0, gridSize * 10 * tileSize); glVertex3f(gridSize, floorHeight, -gridSize); glTexCoord2f(gridSize * 10 * tileSize, gridSize * 10 * tileSize); glVertex3f(gridSize, ceilingHeight, -gridSize); glTexCoord2f(gridSize * 10 * tileSize, 0); glVertex3f(-gridSize, ceilingHeight, -gridSize); // West wall glTexCoord2f(0, 0); glVertex3f(-gridSize, floorHeight, -gridSize); glTexCoord2f(gridSize * 10 * tileSize, 0); glVertex3f(-gridSize, ceilingHeight, -gridSize); glTexCoord2f(gridSize * 10 * tileSize, gridSize * 10 * tileSize); glVertex3f(-gridSize, ceilingHeight, +gridSize); glTexCoord2f(0, gridSize * 10 * tileSize); glVertex3f(-gridSize, floorHeight, +gridSize); // East wall glTexCoord2f(0, 0); glVertex3f(+gridSize, floorHeight, -gridSize); glTexCoord2f(gridSize * 10 * tileSize, 0); glVertex3f(+gridSize, floorHeight, +gridSize); glTexCoord2f(gridSize * 10 * tileSize, gridSize * 10 * tileSize); glVertex3f(+gridSize, ceilingHeight, +gridSize); glTexCoord2f(0, gridSize * 10 * tileSize); glVertex3f(+gridSize, ceilingHeight, -gridSize); // South wall glTexCoord2f(0, 0); glVertex3f(-gridSize, floorHeight, +gridSize); glTexCoord2f(gridSize * 10 * tileSize, 0); glVertex3f(-gridSize, ceilingHeight, +gridSize); glTexCoord2f(gridSize * 10 * tileSize, gridSize * 10 * tileSize); glVertex3f(+gridSize, ceilingHeight, +gridSize); glTexCoord2f(0, gridSize * 10 * tileSize); glVertex3f(+gridSize, floorHeight, +gridSize); glEnd(); glEndList(); int floorDisplayList = glGenLists(1); glNewList(floorDisplayList, GL_COMPILE); glBegin(GL_QUADS); glTexCoord2f(0, 0); glVertex3f(-gridSize, floorHeight, -gridSize); glTexCoord2f(0, gridSize * 10 * tileSize); glVertex3f(-gridSize, floorHeight, gridSize); glTexCoord2f(gridSize * 10 * tileSize, gridSize * 10 * tileSize); glVertex3f(gridSize, floorHeight, gridSize); glTexCoord2f(gridSize * 10 * tileSize, 0); glVertex3f(gridSize, floorHeight, -gridSize); glEnd(); glEndList();

• Android - How do I load a contact Photo?

  - by PaulH

  I'm having trouble loading a photo for a contact in Android. I've googled for an answer, but so far have come up empty. Does anyone have an example of querying for a Contact, then loading the Photo? So, given a contactUri which comes from an Activity result called using startActivityForResult(new Intent(Intent.ACTION_PICK,ContactsContract.CommonDataKinds.Phone.CONTENT_URI),PICK_CONTACT_REQUEST) is: content://com.android.contacts/data/1557 The loadContact(..) works fine. However when I call the getPhoto(...) method, I get a null value for the photo InputStream. It is also confusing because the URI values are different. The contactPhotoUri evaluates to: content://com.android.contacts/contacts/1557 See the comments inline in the code below. class ContactAccessor { /** * Retrieves the contact information. */ public ContactInfo loadContact(ContentResolver contentResolver, Uri contactUri) { //contactUri --> content://com.android.contacts/data/1557 ContactInfo contactInfo = new ContactInfo(); // Load the display name for the specified person Cursor cursor = contentResolver.query(contactUri, new String[]{Contacts._ID, Contacts.DISPLAY_NAME, Phone.NUMBER, Contacts.PHOTO_ID}, null, null, null); try { if (cursor.moveToFirst()) { contactInfo.setId(cursor.getLong(0)); contactInfo.setDisplayName(cursor.getString(1)); contactInfo.setPhoneNumber(cursor.getString(2)); } } finally { cursor.close(); } return contactInfo; // <-- returns info for contact } public Bitmap getPhoto(ContentResolver contentResolver, Long contactId) { Uri contactPhotoUri = ContentUris.withAppendedId(Contacts.CONTENT_URI, contactId); // contactPhotoUri --> content://com.android.contacts/contacts/1557 InputStream photoDataStream = Contacts.openContactPhotoInputStream(contentResolver,contactPhotoUri); // <-- always null Bitmap photo = BitmapFactory.decodeStream(photoDataStream); return photo; } public class ContactInfo { private long id; private String displayName; private String phoneNumber; private Uri photoUri; public void setDisplayName(String displayName) { this.displayName = displayName; } public String getDisplayName() { return displayName; } public void setPhoneNumber(String phoneNumber) { this.phoneNumber = phoneNumber; } public String getPhoneNumber() { return phoneNumber; } public Uri getPhotoUri() { return this.photoUri; } public void setPhotoUri(Uri photoUri) { this.photoUri = photoUri; } public long getId() { return this.id; } public void setId(long id) { this.id = id; } } } Clearly, I'm doing something wrong here, but I can't seem to figure out what the problem is. Thanks.

• Trying to convert simple midlet application to Android application but running into problems.

  - by chobo2

  Hi I am trying to do some threading in Android so I took an old threading assignment I had done fora midlet and took out the midlet code and replaced it with android code(such as textview). package com.assignment1; import android.app.Activity; import android.os.Bundle; import android.widget.TextView; public class Threading extends Activity { private TextView tortose; private TextView hare; private Thread hareThread; private Thread torotoseThread; private int num = 0; private int num2 = 0; public Threading() { } /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); tortose = (TextView) findViewById(R.id.TextView01); hare = (TextView) findViewById(R.id.TextView02); Hare newHare = new Hare(); hareThread = new Thread(newHare); hareThread.start(); Torotose newTortose = new Torotose(); torotoseThread = new Thread(newTortose); torotoseThread.start(); //updateDisplay(); } private synchronized void check(int value1, int value2) { if((value1-value2) >= 10) { try { wait(); } catch(Exception ex) { System.out.println(ex); } } } private synchronized void getGoing(int value1, int value2) { if((value1-value2) == 0) { try { notify(); } catch(Exception ex) { System.out.println(ex); } } } private class Hare extends Thread { public void run() { while(true) { num++; hare.setText(Integer.toString(num)); check(num, num2); try { // are threads different in andriod apps? Thread.sleep(100); // hareThread.sleep(100); } catch(Exception ex) { System.out.println(ex); } } } } private class Torotose extends Thread { public void run() { while(true) { num2++; tortose.setText(Integer.toString(num2)); getGoing(num,num2); try { Thread.sleep(200); //torotoseThread.sleep(200); } catch(Exception ex) { System.out.println(ex); } } } } } First it wanted me to change my threads to like static threads.So is this just how Android does it? Next when I run this code it just crashes with some unexpected error. I am not sure what the error is but when I try to debug it and goes to like to create a new "hare" object it shows me this. // Compiled from ClassLoader.java (version 1.5 : 49.0, super bit) public abstract class java.lang.ClassLoader { // Method descriptor #8 ()V // Stack: 3, Locals: 1 protected ClassLoader();

• Android: retrieving all Drawable resources from Resources object

  - by Matt Huggins

  In my Android project, I want to loop through the entire collection of Drawable resources. Normally, you can only retrieve a specific resource via its ID using something like: InputStream is = Resources.getSystem().openRawResource(resourceId) However, I want to get all Drawable resources where I won't know their ID's beforehand. Is there a collection I can loop through or perhaps a way to get the list of resource ID's given the resources in my project? Or, is there a way for me in Java to extract all property values from the R.drawable static class?

• Azure storage: Uploaded files with size zero bytes

  - by Fabio Milheiro

  When I upload an image file to a blob, the image is uploaded apparently successfully (no errors). When I go to cloud storage studio, the file is there, but with a size of 0 (zero) bytes. The following is the code that I am using: // These two methods belong to the ContentService class used to upload // files in the storage. public void SetContent(HttpPostedFileBase file, string filename, bool overwrite) { CloudBlobContainer blobContainer = GetContainer(); var blob = blobContainer.GetBlobReference(filename); if (file != null) { blob.Properties.ContentType = file.ContentType; blob.UploadFromStream(file.InputStream); } else { blob.Properties.ContentType = "application/octet-stream"; blob.UploadByteArray(new byte[1]); } } public string UploadFile(HttpPostedFileBase file, string uploadPath) { if (file.ContentLength == 0) { return null; } string filename; int indexBar = file.FileName.LastIndexOf('\\'); if (indexBar > -1) { filename = DateTime.UtcNow.Ticks + file.FileName.Substring(indexBar + 1); } else { filename = DateTime.UtcNow.Ticks + file.FileName; } ContentService.Instance.SetContent(file, Helper.CombinePath(uploadPath, filename), true); return filename; } // The above code is called by this code. HttpPostedFileBase newFile = Request.Files["newFile"] as HttpPostedFileBase; ContentService service = new ContentService(); blog.Image = service.UploadFile(newFile, string.Format("{0}{1}", Constants.Paths.BlogImages, blog.RowKey)); Before the image file is uploaded to the storage, the Property InputStream from the HttpPostedFileBase appears to be fine (the size of the of image corresponds to what is expected! And no exceptions are thrown). And the really strange thing is that this works perfectly in other cases (uploading Power Points or even other images from the Worker role). The code that calls the SetContent method seems to be exactly the same and file seems to be correct since a new file with zero bytes is created at the correct location. Does any one have any suggestion please? I debugged this code dozens of times and I cannot see the problem. Any suggestions are welcome! Thanks

• How to dump ASP.NET Request headers to string

  - by FreshCode

  I'd like to email myself a quick dump of a GET request's headers for debugging. I used to be able to do this in classic ASP simply with the Request object, but Request.ToString() doesn't work. And the following code returned an empty string: using (StreamReader reader = new StreamReader(Request.InputStream)) { string requestHeaders = reader.ReadToEnd(); // ... // send requestHeaders here }

• Connect MySQL database from Android

  hello people! well this is the code snippet i use to access the getUser.php to retrive user details from a MySQL database in my application: String result = ""; //the year data to send ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(); nameValuePairs.add(new BasicNameValuePair("uid","demo")); //http post try{ HttpClient httpclient = new DefaultHttpClient(); HttpPost httppost = new HttpPost("http://192.xxx.xx.xxx/getUser.php"); httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs)); HttpResponse response = httpclient.execute(httppost); HttpEntity entity = response.getEntity(); InputStream is = entity.getContent(); }catch(Exception e){ Log.e("log_tag", "Error in http connection "+e.toString()); } //convert response to string try{ InputStream is = null; BufferedReader reader = new BufferedReader(new InputStreamReader(is,"iso-8859-1"),8); StringBuilder sb = new StringBuilder(); String line = null; while ((line = reader.readLine()) != null) { sb.append(line + "\n"); } is.close(); result=sb.toString(); }catch(Exception e){ Log.e("log_tag", "Error converting result "+e.toString()); } //parse json data try{ JSONArray jArray = new JSONArray(result); for(int i=0;i<jArray.length();i++){ JSONObject json_data = jArray.getJSONObject(i); Log.i("log_tag","id: "+json_data.getInt("id")+ ", name: "+json_data.getString("fname")+ ", sex: "+json_data.getInt("sex")+ ", birthyear: "+json_data.getInt("dob") ); } } catch(JSONException e){ Log.e("log_tag", "Error parsing data "+e.toString()); } } This snippet is taken from http://helloandroid.com Everything is configured fine: the MySQL Db, IIS with FASTCGi, PHP tools and drivers. even the script below when called from browser with url: http://192.xxx.xx.x.xxx/getUser.php?uid=demo works fine, But returns error in android with java.lang.NullPointerException and org.json.JSONEXCEPTION: End of input at character 0 <?php mysql_connect("myhost","username","pwd"); mysql_select_db("mydb"); $q=mysql_query("SELECT * FROM userinfo WHERE uid ='".$_REQUEST['uid']."'"); while($e=mysql_fetch_assoc($q)) $output[]=$e; print(json_encode($output)); mysql_close(); ?> Can anybody help in this section?

• How do I substitute an xsd when using dom4j?

  - by HappyEngineer

  I'm using dom4j to load an xml file which references an xsd. If the xml file references the xsd http://foo/bar.xsd, how can I tell dom4j to instead use an xsd file located in the classpath? I was hoping that I could open an inputstream to the local xsd and then pass that to dom4j to use when it encounters that url. The next best thing would be to just have dom4j use an alternate url that could point to a local file like file:///c:/foo/bar.xsd.

• Android HttpsURLConnection and JSON for new GCM

  - by Ryan Gray

  I'm overhauling certain parts of my app to use the new GCM service to replace C2DM. I simply want to create the JSON request from a Java program for testing and then read the response. As of right now I can't find ANY formatting issues with my JSON request and the google server always return code 400, which indicates a problem with my JSON. http://developer.android.com/guide/google/gcm/gcm.html#server JSONObject obj = new JSONObject(); obj.put("collapse_key", "collapse key"); JSONObject data = new JSONObject(); data.put("info1", "info_1"); data.put("info2", "info 2"); data.put("info3", "info_3"); obj.put("data", data); JSONArray ids = new JSONArray(); ids.add(REG_ID); obj.put("registration_ids", ids); System.out.println(obj.toJSONString()); I print my request to the eclipse console to check it's formatting byte[] postData = obj.toJSONString().getBytes(); try{ URL url = new URL("https://android.googleapis.com/gcm/send"); HttpsURLConnection.setDefaultHostnameVerifier(new JServerHostnameVerifier()); HttpsURLConnection conn = (HttpsURLConnection) url.openConnection(); conn.setDoOutput(true); conn.setDoInput(true); conn.setUseCaches(false); conn.setRequestMethod("POST"); conn.setRequestProperty("Content-Type", "application/json"); conn.setRequestProperty("Authorization", "key=" + API_KEY); System.out.println(conn.toString()); OutputStream out = conn.getOutputStream(); // exception thrown right here. no InputStream to get InputStream in = conn.getInputStream(); byte[] response = null; out.write(postData); out.close(); in.read(response); JSONParser parser = new JSONParser(); String temp = new String(response); JSONObject temp1 = (JSONObject) parser.parse(temp); System.out.println(temp1.toJSONString()); int responseCode = conn.getResponseCode(); System.out.println(responseCode + ""); } catch(Exception e){ System.out.println("Exception thrown\n"+ e.getMessage()); } } I'm sure my API key is correct as that would result in error 401, so says the google documentation. This is my first time doing JSON but it's easy to understand because of its simplicity. Anyone have any ideas on why I always receive code 400? update: I've tested the google server example classes provided with gcm so the problem MUST be with my code.

• Java multithreaded server - each connection returns data. Processing on main thread?

  - by oliwr

  I am writing a client with an integrated server that should wait indefinitely for new connections - and handle each on a Thread. I want to process the received byte array in a system wide available message handler on the main thread. However, currently the processing is obviously done on the client thread. I've looked at Futures, submit() of ExecutorService, but as I create my Client-Connections within the Server, the data would be returned to the Server thread. How can I return it from there onto the main thread (in a synchronized packet store maybe?) to process it without blocking the server? My current implementation looks like this: public class Server extends Thread { private int port; private ExecutorService threadPool; public Server(int port) { this.port = port; // 50 simultaneous connections threadPool = Executors.newFixedThreadPool(50); } public void run() { try{ ServerSocket listener = new ServerSocket(this.port); System.out.println("Listening on Port " + this.port); Socket connection; while(true){ try { connection = listener.accept(); System.out.println("Accepted client " + connection.getInetAddress()); connection.setSoTimeout(4000); ClientHandler conn_c= new ClientHandler(connection); threadPool.execute(conn_c); } catch (IOException e) { System.out.println("IOException on connection: " + e); } } } catch (IOException e) { System.out.println("IOException on socket listen: " + e); e.printStackTrace(); threadPool.shutdown(); } } } class ClientHandler implements Runnable { private Socket connection; ClientHandler(Socket connection) { this.connection=connection; } @Override public void run() { try { // Read data from the InputStream, buffered int count; byte[] buffer = new byte[8192]; InputStream is = connection.getInputStream(); ByteArrayOutputStream out = new ByteArrayOutputStream(); // While there is data in the stream, read it while ((count = is.read(buffer)) > 0) { out.write(buffer, 0, count); } is.close(); out.close(); System.out.println("Disconnect client " + connection.getInetAddress()); connection.close(); // handle the received data MessageHandler.handle(out.toByteArray()); } catch (IOException e) { System.out.println("IOException on socket read: " + e); e.printStackTrace(); } return; } }
