    - by Firstthumb
    I am developing a GWT-Spring-Hibernate project and I want to use Spring Autowired annotation in GWT Service Servlet but my autowired annotated service is not injected. it is null. Is there a configuration detail that I missed? I add <context:annotation-config /> <context:component-scan base-package="com.org" /> to my ApplicationContext.xml and I have annotated my service as @Service("myService") @Autowired MyService myService; // This is null so WHY?

  • KeybListener problem

    - by rgksugan
    In my apllication i am using a jpanel in which i want to add a key listener. I did it. But it doesnot work. Is it because i am using a swingworker to update the contents of the panel every second. Here is my code to update the panel RenderedImage image = ImageIO.read(new ByteArrayInputStream((byte[]) get())); Graphics graphics = remote.rdpanel.getGraphics(); if (graphics != null) { Image readyImage = new ImageIcon(UtilityFunctions.convertRenderedImage(image)).getImage(); graphics.drawImage(readyImage, 0, 0, remote.rdpanel.getWidth(), remote.rdpanel.getHeight(), null); }

  • Writing out sheet to text file using POI event model

    - by Eduardo Dennis
    I am using XLSX2CSV example to parse large sheets from a workbook. Since I only need to output the data for specific sheets I added an if statement in the process method to test for the specific sheets. When the condition is met I continue with the process. public void process() throws IOException, OpenXML4JException, ParserConfigurationException, SAXException { ReadOnlySharedStringsTable strings = new ReadOnlySharedStringsTable(this.xlsxPackage); XSSFReader xssfReader = new XSSFReader(this.xlsxPackage); StylesTable styles = xssfReader.getStylesTable(); XSSFReader.SheetIterator iter = (XSSFReader.SheetIterator) xssfReader.getSheetsData(); while (iter.hasNext()) { InputStream stream = iter.next(); String sheetName = iter.getSheetName(); if (sheetName.equals("SHEET1")||sheetName.equals("SHEET2")||sheetName.equals("SHEET3")||sheetName.equals("SHEET4")||sheetName.equals("SHEET5")){ processSheet(styles, strings, stream); try { System.setOut(new PrintStream( new FileOutputStream("C:\\Users\\edennis.AD\\Desktop\\test\\"+sheetName+".txt"))); } catch (Exception e) { e.printStackTrace(); } stream.close(); } } } But I need to output text file and not sure how to do it. I tried to use the System.set() method to output everything from system.out to text but that's not working I just get blank files.

  • Generate encoding String according to creation order.

    - by Tony
    I need to generate encoding String for each item I inserted into the database. for example: x00001 for the first item x00002 for the sencond item x00003 for the third item The way I chose to do this is counting the rows. Before I insert the third item, I count against the database, I know there're already 2 rows, so the next encoding is ended with 3. But there is a problem. If I delete the second item, the forth item will not be the x00004,but x00003. I can add additional columns to table, to store the next encoding, I don't know if there's other better solutions ?

  • I have a ConnectException that isn't being caught for some reason

    - by aakbari1024
    I'm working on an Android application that uses sockets. I have a function called initializeStreams() which opens the socket and attempts a connection. This function throws a ConnectException if the connection could not be established. But for some reason, in the code that calls initializeStreams(), which has a catch block for ConnectException, the log prints out its own stack trace for the exception instead of going to the catch block. The catch block is never reached at all, even though the exact exception is being thrown. Here's the code: The try block: try { initializeStreams(); /* drivesList = new ArrayList<String>(); drivesList = enumerateDrives();*/ } catch (ConnectException e) { //Log.i(TAG, "caught connect exception"); /*loadingProgress.dismiss(); retryConnection();*/ } initializeStreams(): public void initializeStreams() throws ConnectException { try { Log.i(TAG, "Attempting to connect"); requestSocket = new Socket(SERVER_ADDR, PORT); /* other code */ } catch (IOException e) { e.printStackTrace(); } I can't figure this out, so any help would be much appreciated. }

  • No operations allowed after statement closed issue

    - by Washu
    I have the next methods in my singleton to execute the JDBC connections public void openDB() throws ClassNotFoundException, IllegalAccessException, InstantiationException, SQLException { Class.forName("com.mysql.jdbc.Driver").newInstance(); String url = "jdbc:mysql://localhost/mbpe_peru";//mydb conn = DriverManager.getConnection(url, "root", "admin"); st = conn.createStatement(); } public void sendQuery(String query) throws SQLException { st.executeUpdate(query); } public void closeDB() throws SQLException { st.close(); conn.close(); } And I'm having a problem in a void where i have to call this twice. private void jButton1ActionPerformed(ActionEvent evt) { Main.getInstance().openDB(); Main.getInstance().sendQuery("call insertEntry('"+EntryID()+"','"+SupplierID()+"');"); Main.getInstance().closeDB(); Main.getInstance().openDB(); for(int i=0;i<dataBox.length;i++){ Main.getInstance().sendQuery("call insertCount('"+EntryID()+"','"+SupplierID()+"','"+BoxID()+"'); Main.getInstance().closeDB(); } } I have already tried to keep the connection open and send the 2 querys and after that closed and it didnt work... The only way it worked was to not use the methods, declare the commands for the connection and use different variables for the connection and the statement. I thought that if i close the Connecion and the Statement I could use the variable once again since is a method but I'm not able to. Is there any way to solve this using my methods for the JDBC connection?

  • Eclipse: find resource on classpath

    - by seanizer
    Is there a way in eclipse to search the classpath for arbitrary resource file names (or patterns)? I know I can use either Navigate > Open Type (which will scan the classpath for classes) or Navigate > Open Resource, which will search for any resource type, but only in my project folders. Is there any way to achieve a combination ob both, to do a resource search (something like *.xsd) that searches all jars on the classpath?

  • Is there a way to filter out offensive words from Jcaptcha?

    - by elduff
    We are using JCaptcha for a captcha tool in a small app that my team is writing. However, just during development time (on a small team - 4 of us), we've run across a number of curse words and other potentially offensive words for the actual captchas. Is there a way to filter out potentially offensive words so that they are not presented to the user?

  • Text input for multi-valued attribute

    - by Sean
    I need to create an input form that will allow a user to enter any number of values for a particular attribute. I've tried several approaches, all of which seem to have various levels of failure. The latest model bean looks something like: public class Product { private String name; private String[] tags; ...accessors... } The input fields look something like: <h:inputText id="name" value="#{product.name}"></h:inputText> <h:inputText id="tag0" value="#{product.tag[0]}"></h:inputText> My plan was to allow the user is to use javascript to add additional form fields as needed. This type of setup gives me a 'Target Unreachable' error. What am I missing? I am using JSF 1.1 on WebSphere 6.1

  • OnClickListener onClick=true and selector

    - by azerto00
    I have not found any answer for my problem, so I need your help ... I have an LinearLayout which I want to be clickable in order to lunch another activity. So I implement an onClickListener to it. I created an selector for this LinearLayout in order that what someone click on it, the background change. I just don't understand that : If my LinearLayout doesn't have android:clickable="true" in the xml, I'm able to click on it and get what I want but the selector doesn't work. If I remove this line, it is the opposite .. the selector work but not the onClick event. So, can anyone can explain me why ? Just in case, here is my the content of my selector file : <selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:drawable="@drawable/btn_restaurants_background_state_pressed" android:state_pressed="true"></item> <item android:drawable="@drawable/btn_restaurants_background_state_pressed" android:state_focused="true"></item> <item android:drawable="@drawable/btn_restaurants_background_state_pressed" android:state_selected="true"></item> <item android:drawable="@drawable/btn_restaurants_background_state_normal"></item> </selector> Thanks you in advance

Exemple : Eager in place of Lazy can change dramaticly the response time....

  • Getting a JFrame's actual current location

    - by Ian Fellows
    Hello community, I am trying to create a (child) JFrame which slides out from underneath one side of a second (parent) JFrame. The goal is to then have the child follow the parent around when it is moved, and respond to resizing events. This is somewhat related to this question. I have tried using a ComponentListener, but with this method the child only moves once the parent has come to a stop, whereas I would like the child to move as the parent is dragged around the screen. Another option I attempted was to start a new refresher thread that continually updated the child's location using getLocation() or getLocationOnScreen(), but the lag was the same as with ComponentListener. Is there a way to get the true actual location of a JFrame even in the midst of a drag? or if not, is there a way to get the effect of a sheet sliding out from underneath and following the Frame around?

  • Compiling error with API 10

    - by Suhel De Corser
    I was following the basic tutorials on developers.android.com and came by creating the activity named DisplayMessageActivity. It is a blank activity with all the specifications given as shown in the tutorial. FYI, I am using Min SDK = API 8, Target SDK = API 16, Compile with = API 10 The next thing is that there are two errors: "The method getActionBar() is undefined for the type DisplayMessageActivity "home cannot be resolved or is not a field" I tried changing the API to 14 which called for another problem, it wants the minimum API to be 11. That solves these problems, but the main problem is so many devices still use Gingerbread or maybe FroYo. Can't I write for them? Do I have to go higher? How to write for them?

  • How to set specific column settings in JTable?

    - by HansDampf
    How can I make my JTable show specific stuff for each column? Can I use an Object for more than one column? I want to have a column showing the date (dd.mm.yyyy) and another to show the time (hh:mm) but as I have it now it only shows the String representation of the Date object as a whole. public class AppointmentTableModel extends AbstractTableModel { ... @Override public Object getValueAt(int rowIndex, int columnIndex) { return appointments.get(rowIndex).getByColumn(columnIndex); } } public class Appointment { ... public Object getByColumn(int columnIndex) { switch (columnIndex) { case 0: return date; case 1: return date; case 2: return sample; case 3: return sample; case 4: return history; case 5: return comment; } return null; } }

  • Excel workbooks produced by POI don't work when linked

    - by Eric Nicolas
    Here is what I'm doing : Create a workbook in memory (book = new HSSFWorkbook(), ...) Save it to disk (book.write(...)) Open in Excel (ok) Create another workbook in Excel, which links to the first one (=PoiWorkbook?xls!A1) Close Excel Then everytime I open the second workbook again, all the links are #N/A, unless I also open the POI-generated workbook at the same time. I never saw this behaviour with standard workbooks created in Excel. Anyone has seen this and found a workaround ? Thanks.

  • How to determine whether a spread-sheet cell contains a date, or a real number?

    - by Everyone
    When a cell in a spreadsheet contains a simple date (mm/dd/yyyy) the poi API flags the cell-type as 'numeric'. This is probably because spreadsheets ( IMO ) historically recognize only strings and real numbers. It is possible to hard-code the cell-index, and use it conditionally to call 'getDateCellValue'. But this feels like a hack. What other ways are there in the poi API to determine whether the content in a cell is a Date rather than a real number?

  • Spring 3 - Theme with separate JSP

    - by Max
    Hi, I'm trying to rewrite some Spring 1.2 code to Spring 3.0 one. Currently I'm stuck with JSP resolved by URL problem. Application uses separate JSP files with different layouts for serving the same model from the same controller. The JSP is switched using interceptor, that intercepts the url and changes the view. For example: /design_one/mypage.htm -> MyPageController -> /design_one/mypage.jsp /design_two/mypage.htm -> MyPageController -> /design_two/mypage.jsp Is there a way to make same or similar functionality using something better than raw interceptors?
