• How to bring up list of available notification sounds on Android

  - by robintw

  I'm creating notifications in my Android application, and would like to have an option in my preferences to set what sound is used for the notification. I know that in the Settings application you can choose a default notification sound from a list. Where does that list come from, and is there a way for me to display the same list in my application?

• How do I make JPA POJO classes + Netbeans forms play well together?

  - by Zak

  I started using netbeans to design forms to edit the instances of various classes I have made in a small app I am writing. Basically, the app starts, an initial set of objects is selected from the DB and presented in a list, then an item in the list can be selected for editing. When the editor comes up it has form fields for many of the data fields in the class. The problem I run into is that I have to create a controller that maps each of the data elements to the correct form element, and create an inordinate number of small conversion mapping lines of code to convert numbers into strings and set the correct element in a dropdown, then another inordinate amount of code to go back and update the underlying object with all the values from the form when the save button is clicked. My question is; is there a more directly way to make the editing of the form directly modify the contents of my class instance? I would like to be able to have a default mapping "controller" that I can configure, then override the getter/setter for a particular field if needed. Ideally, there would be standard field validation for things like phone numbers, integers, floats, zip codes, etc... I'm not averse to writing this myself, I would just like to see if it is already out there and use the right tool for the right job.

• SPRING: How do you programmatically instantiate classes based on information passed from Flex UI

  - by babyangel86

  Imagine the UI passes back an XMl node as such: <properties> <type> Source </type> <name> Blooper </name> <delay> <type> Deterministic </type> <parameters> <param> 4 </param> </parameters> <delay> <batch> <type> Erlang </type> <parameters> <param> 4 </param> <param> 6 </param> </parameters> <batch> And behind the scene what it is asking that you instantiate a class as such: new Source("blooper", new Exp(4), new Erlang(4,6); The problem lies in the fact that you don't know what class you will need to processing, and you will be sent a list of these class definitions with instructions on how they can be linked to each other. I've heard that using a BeanFactoryPostProcessor might be helpful, or a property editor/convertor. However I am at a loss as to how best to use them to solve my problem. Any help you can provide will be much appreciated.

• Restore previously serialized JFrame-object, how?

  - by elementz

  Hi all. I have managed to serialize my very basic GUI-object containing a JTextArea and a few buttons to a file 'test.ser'. Now, I would like to completely restore the previously saved state from 'test.ser', but seem to have a misconception of how to properly deserialize an objects state. The class MyFrame creates the JFrame and serializes it. public class MyFrame extends JFrame implements ActionListener { // Fields JTextArea textArea; String title; static MyFrame gui = new MyFrame(); private static final long serialVersionUID = 1125762532137824262L; /** * @param args */ public static void main(String[] args) { // TODO Auto-generated method stub gui.run(); } // parameterless default contructor public MyFrame() { } // constructor with title public MyFrame(String title) { } // creates Frame and its Layout public void run() { JFrame frame = new JFrame(title); JPanel panel_01 = new JPanel(); JPanel panel_02 = new JPanel(); JTextArea textArea = new JTextArea(20, 22); textArea.setLineWrap(true); JScrollPane scrollPane = new JScrollPane(textArea); scrollPane.setVerticalScrollBarPolicy(ScrollPaneConstants.VERTICAL_SCROLLBAR_AS_NEEDED); panel_01.add(scrollPane); // Buttons JButton saveButton = new JButton("Save"); saveButton.addActionListener(this); JButton loadButton = new JButton("Load"); loadButton.addActionListener(this); panel_02.add(loadButton); panel_02.add(saveButton); // Layout frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.getContentPane().add(BorderLayout.CENTER, panel_01); frame.getContentPane().add(BorderLayout.SOUTH, panel_02); frame.setSize(300, 400); frame.setVisible(true); } /* * */ public void serialize() { try { ObjectOutputStream oos = new ObjectOutputStream(new FileOutputStream("test.ser")); oos.writeObject(gui); oos.close(); } catch (Exception e) { // TODO: handle exception e.printStackTrace(); } } public void actionPerformed(ActionEvent ev) { System.out.println("Action received!"); gui.serialize(); } } Here I try to do the deserialization: public class Deserialize { static Deserialize ds; static MyFrame frame; public static void main(String[] args) { try { ObjectInputStream ois = new ObjectInputStream(new FileInputStream("test.ser")); frame = (MyFrame) ois.readObject(); ois.close(); } catch (FileNotFoundException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (ClassNotFoundException e) { // TODO Auto-generated catch block e.printStackTrace(); } } Maybe somebody could point me into the direction where my misconception is? Thx in advance!

• getRequestProperty("Authorization") always returns null

  - by Thilo

  I am trying to read the authorization header for an HTTP request (because I need to add something to it), but I always get null for the header value. Other headers work fine. public void testAuth() throws MalformedURLException, IOException{ URLConnection request = new URL("http://google.com").openConnection(); request.setRequestProperty("Authorization", "MyHeader"); request.setRequestProperty("Stackoverflow", "anotherHeader"); // works fine assertEquals("anotherHeader", request.getRequestProperty("Stackoverflow")); // Auth header returns null assertEquals("MyHeader", request.getRequestProperty("Authorization")); } Am I doing something wrong? Is this a "security" feature? Is there a way to make this work with URLConnection, or do I need to use another HTTP client library?

• JavaME FileConnection url

  - by Trimack

  Hi there, I want to save data to my Sony Ericsson K750i. I know the phone implements FileConnection version 1.0. The list of roots taken from FileSystemRegistry.listRoots(); returns single element named "c:/". I want to save a file.txt just about anywhere, but preferably to the memory stick attached. Unfortunately, it doesn't seem to work. It throws an IOException without any message. I tried opening the fileconnection on numerous roots like c:/, C:/, /, ./, root1/, SDCard/, CFCard/, MemoryStick/ and perhaps some more but without any luck. The exception is thrown right after this line for any of those roots: FileConnection filecon = (FileConnection) Connector.open("file:///MemoryStick/file.txt"); Please, what URL should i use?

• Help with calling a secure (SSL) webservice in Android.

  - by mmattax

  I'm new to Android and am struggling to make a call to an SSL web service for an Android Application. My code is as follows: Log.v("fs", "Making HTTP call..."); HttpClient http = new DefaultHttpClient(); HttpGet request = new HttpGet("https://example.com/api"); try { String response = http.execute(request, new BasicResponseHandler()); Log.v("fs", response); } catch (Exception e) { Log.v("fs", e.toString()); } The Output is: Making HTTP call... javax.net.SSLPeerUnverifiedException: No peer certificate Any suggestions to make this work would be great. EDIT I should note that this is a valid cert. It is not self-signed.

• Configuring Hadoop logging to avoid too many log files

  - by Eric Wendelin

  I'm having a problem with Hadoop producing too many log files in $HADOOP_LOG_DIR/userlogs (the Ext3 filesystem allows only 32000 subdirectories) which looks like the same problem in this question: http://stackoverflow.com/questions/2091287/error-in-hadoop-mapreduce My question is: does anyone know how to configure Hadoop to roll the log dir or otherwise prevent this? I'm trying to avoid just setting the "mapred.userlog.retain.hours" and/or "mapred.userlog.limit.kb" properties because I want to actually keep the log files. I was also hoping to configure this in log4j.properties, but looking at the Hadoop 0.20.2 source, it writes directly to logfiles instead of actually using log4j. Perhaps I don't understand how it's using log4j fully. Any suggestions or clarifications would be greatly appreciated.

• Is serialVersioUID require in Interfaces(I hope not)?

  - by learner

  My understanding is serialVersionUID is applicable only to classes, because we can create an object only to classes and the concept of serialVersionUID is for object serialization and deserialization.

• No Hibernate Exception on the same insert of data

  - by Mark Estrada

  Hi All, Hibernate Newbie here. I am quite unsure why I am not getting any exception when I am executing below code. On first attempt, this code creates the Book Entry on my Book Table. But my concern is that when I execute below code again, no error was pop out by Hibernate. I was in fact expecting some sort of Violation of Primary Key Constraints as what I have bee doing in JDBC code. public class BookDao { public void createBook(Book bookObj) { Session session = HibernateUtil.getSessionFactory() .getCurrentSession(); session.beginTransaction(); session.saveOrUpdate(bookObj); session.getTransaction().commit(); } } public class HibernateUtil { private static final SessionFactory sessionFactory = buildSessionFactory(); private static SessionFactory buildSessionFactory() { try { // Create the SessionFactory from hibernate.cfg.xml return new AnnotationConfiguration().configure() .buildSessionFactory(); } catch (Throwable ex) { // Make sure you log the exception, as it might be swallowed ex.printStackTrace(); throw new ExceptionInInitializerError(ex); } } public static SessionFactory getSessionFactory() { return sessionFactory; } } public class BookDBStarter { public static void main(String[] args) { Book bookHF = new Book(); bookHF.setIsbn("HF-12345"); bookHF.setName("Head First HTML"); bookHF.setPublishDate(new Date()); BookDao daoBook = new BookDao(); daoBook.createBook(bookHF); } } Is this normal hibernate way? And how will I know if my insert is successful? Any thoughts?

• j2ME setLocationListener()

  - by Jeff Catania

  I'm programming a GPS tracking system using the Motorola i335 running on Sprint's IDEN network. I'm using the javax.microedition.location api to find the GPS coordinates. To set up the updating, you use the [setLocationListener][1] method. I originally tried passing (listener,2,1,1). However there was too many invalid locations being received (where the GPS could not get the fix in the specified time), so I changed the parameters to (listener, 20, 20, 1). Now the system barely throws any invalid locations. My goal is to get the fastest number of updates that are realistic. Have any of you found a happy medium for parameters of this method?

• How to use an IN clause in iBATIS?

  - by furtelwart

  I'm using iBATIS to create select statements. Now I would like to implement the following SQL statement with iBATIS: SELECT * FROM table WHERE col1 IN ('value1', 'value2'); With the following approach, the statement is not prepared correctly and no result returns: SELECT * FROM table WHERE col1 IN #listOfValues#; iBATIS seems to restructure this list and tries to interpret it as a string. How can I use the IN clause correctly?

• Resizing a GLJPanel with JOGL causes my model to disappear.

  - by badcodenotreat

  I switched over to using a GLJPanel from a GLCanvas to avoid certain flickering issues, however this has created several unintended consequences of it's own. From what I've gleaned so far, GLJPanel calls GLEventListener.init() every time it's resized which either resets various openGL functions i've enabled in init() (depth test, lighting, etc...) if i'm lucky, or completely obliterates my model if i'm not. I've tried debugging it but I'm not able to correct this behavior. This is my init() function: gl.glShadeModel( GL.GL_SMOOTH ); gl.glEnable( GL.GL_DEPTH_TEST ); gl.glDepthFunc( GL.GL_LEQUAL ); gl.glDepthRange( zNear, zFar ); gl.glDisable( GL.GL_LINE_SMOOTH ); gl.glEnable(GL.GL_NORMALIZE); gl.glEnable( GL.GL_BLEND ); gl.glBlendFunc( GL.GL_SRC_ALPHA, GL.GL_ONE_MINUS_SRC_ALPHA ); // set up the background color gl.glClearColor( ((float)backColor.getRed () / 255.0f), ((float)backColor.getGreen() / 255.0f), ((float)backColor.getBlue () / 255.0f), 1.0f); gl.glEnable ( GL.GL_LIGHTING ); gl.glLightfv( GL.GL_LIGHT0, GL.GL_AMBIENT, Constants.AMBIENT_LIGHT, 0 ); gl.glLightfv( GL.GL_LIGHT0, GL.GL_DIFFUSE, Constants.DIFFUSE_LIGHT, 0 ); gl.glEnable ( GL.GL_LIGHT0 ); gl.glTexEnvf( GL.GL_TEXTURE_ENV, GL.GL_TEXTURE_ENV_MODE, GL.GL_MODULATE ); gl.glHint( GL.GL_PERSPECTIVE_CORRECTION_HINT, GL.GL_NICEST ); // code to generate model Is there any way around this other than removing everything from init(), adding it to my display() function? Given the behavior of init() and reshape() for GLJPanel, i'm not sure if that will fix it either.

• How to preserve object identity across different VMs

  - by wheleph

  To be specific let me illustrate the question with Spring http-remoting example. Suppose we have such implementation of a simple interface: public SearchServiceImpl implements SearchService { public SearchJdo processSearch(SearchJdo search) { search.name = "a funky name"; return search; } } SearchJdo is itself a simple POJO. Now when we call the method from a client through http-remoting we'll get: public class HTTPClient { public static void main(final String[] arguments) { final ApplicationContext context = new ClassPathXmlApplicationContext( "spring-http-client-config.xml"); final SearchService searchService = (SearchService) context.getBean("searchService"); SearchJdo search = new SearchJdo(); search.name = "myName"; // this method actually returns the same object it gets as an argument SearchJdo search2 = searchService.processSearch(search); System.out.println(search == search2); // prints "false" } } The problem is that the search objects are different because of serializaton although from logical prospective they are the same. The question is whether there are some technique that allows to support or emulate object identity across VMs.

• JSF: Showing/Calling a dialog programatically

  - by Sway

  has anybody an idea to show/call a dialog programatically and add this to stage(actual browser window) ?! I am running in circles and cannot find a solution :/ More background what I want to do: I want to trigger a database update every 2 hours. This I have done with a TimerTask... This works fine for me, the Timertask gets all the data I want from the database... Before this TimerTask is triggered I want to "lock" the screen for some seconds that no user(session scoped) can access the database(this I also know how this will work) ... My problem is that I don't know/ cannot find a way/ i am to stupid to call a dialog programatically ... Any tips, hints would be very cool :) Thanks a lot ! UPDATE: I want to set this primefaces dialog: Dialog dialog = new Dialog(); dialog.setAppendToBody(true); dialog.setModal(true); dialog.setVisible(true); dialog.setWidgetVar("generatedDialog"); dialog.setId("fancyDialog"); dialog.setClosable(false); dialog.setHeader("Getting latest information from the database"); dialog.setDynamic(true); dialog.setResizable(false); dialog.setDraggable(false); How can I do that ? :/ How do I display it to my browser ? :o Regards

• Google App Engine - Cannot See Children in Datastore Viewer

  - by Taylor L

  I have the following kinds/relationships in my datastore: UserAccount 1-to-1 PersistentLogin 1-to-many PersistentLogins They are all in the same entity group and UserAccount is the parent. Should I expect to see the other kinds in the datastore viewer? Currently, I only see UserAccount entities, but I'm pretty confident the other entities are there because my code is working as expected. Is this just a nuance of the datastore viewer?

• Request attributes in jsf / icefaces behaves strange (survive request end)

  - by hubertg

  I have the following code in a listener method: FacesContext.getCurrentInstance().getExternalContext().getRequestMap().put("time", new Date()); When a button is clicked the following code is executed System.out.println(FacesContext.getCurrentInstance().getExternalContext().getRequestMap().get("time")); One could except that "time" is null when the listener was not executed while processing the current request, but: it seems like the "time" object survives the request processing. So when "time" has been set sometimes in the past it stays there... can anybody explain this? Thanks.

• Single log file for multiple webapps

  - by Ashish Aggarwal

  In my tomcat there are multiple webapps deployed and they communicate with each other. Currently they all have their own log file. But when there is some issue comes from call I have to 1st check with the app to whom I made a call and check log file of respective apps involved in the call. So I want that, as all apps is deployed in same tomcat and sharing a common log4j, if a call made to any app then all logs should be in a single log file and no matters how my webapps are involved all error comes from any webapp during the call should be in a single log file. I have no idea how can I achieve this. So any help is appreciable. Edited: I think my question is not cleared so updated with use case: I have three webapps A, B, C having logs files as A.log, B.log and C.log. I made two calls. 1st one to A (that internally calls C) and 2nd to B (that internally calls C). Now logging of first call must be in A.log (with the logs of every step performed inside the webapp c) and second call must be in B.log (with the logs of every step performed inside the webapp c).

• Jaxb Simplify Plugin

It is attached to a wrong place, or its inconsistent with other bindings. i used exactly the configuration, i also have other jaxb plugins which work, so i am not quite sure, if the plugin is broken or something? has anybody managed to get this running?
