  • Wicket Drag and drop functionality for adding an image

    - by Marcel
    I'm making a wicket app that can manage some options for a cashdesk app. One of the options is to change the image of a selected Product. The user(manager) can choose from the already present images in the database (SQL) when this option is selected, or add a new image if the desired image is not present. Don't mention the test names and awesome images (it's still in test-fase) I prefer to see the adding of an image achieved by Drag and Drop html5 demo [dnd-upload] (From the desktop into the browser) I'm currently using Wicket-6.2.0 and wicket-dnd 0.5.0 and i can't seem to get this working! All examples I can find are from wicket 2.x or lower. It is possible to use drag and drop in Wicket-6.2, but how do I achieve this? There seems to be some DraggableBehavior in wicket? Any help is welcome! [UPDATE] Upgraded to wicket-dnd 0.6

  • Is it possible to inject a bean into a spring form bean

    - by Mike
    I tried to do it 2 different ways, but neither way worked. @Component public class EmailForm{ ... private QuestionDAO questionDAO; ... @Autowired public void setQuestionDAO(QuestionDAO questionDAO) { this.questionDAO = questionDAO; } ... Another way: @Component public class EmailForm implements ApplicationContextAware { ... public void setApplicationContext(ApplicationContext applicationContext) throws BeansException { this.questionDAO = (QuestionDAO)applicationContext.getBean("questionDAO"); } ... Neither way results in questionDAO being injected Form bean is populated by spring: @RequestMapping(method = RequestMethod.POST) public String submit(@Valid final EmailForm emailForm, BindingResult result, final Model model) {

  • How to save file and read

    - by Jessy
    Hello everyone, I create a program that place random image in grid layout format. The size of the grid layout is 6 x 6 = 36. Only 10 were filled with images (each image was different) and the rest were empty. freeimagehosting.net/uploads/bfb7e85f63.jpg How can I save it to a file and read it again, so it will display the same images with same placement on the grid? Here is the code that I used to save the images: //image file String []arrPic = {"pic1.jpg","pic2.jpg","pic3.jpg","pic4.jpg","pic5.jpg","pic6.jpg","pic7.jpg","pic8.jpg","pic9.jpg","pic10.jpg",,"pic11.jpg","pic12.jpg","pic13.jpg"}; ArrayList<String> pictures = new ArrayList<String>(Arrays.asList(arrPic)); ArrayList<String> file = new ArrayList<String>(); JPanel pDraw = new JPanel(new GridLayout(6,6,2,2)); ... //fill all grids with empty label for (int i =0; i<(6*6); i++){ JLabel lbl = new JLabel(""); pDraw.add(lbl); } ... //Choose random box to be filled with images for(int i=0; i<10; i++){ Boolean number = true; while(number){ int n = rand.nextInt(35); if(!(arraylist.contains(n))) number = false; arraylist.add(n); } //fill the grids with images for(int i=0; i<arraylist.size(); i++){ //select random image from arraylist int index = rand.nextInt (pictures.size()); String fileName = (String) pictures.get(index ); //find the image file icon = createImageIcon(fileName); //save the file in a new file file.add(fileName); //rescaled the image int x = rand.nextInt(50)+50; int y = rand.nextInt(50)+50; Image image = icon.getImage().getScaledInstance(x,y,Image.SCALE_SMOOTH); icon.setImage(image); //remove empty label and replace it with an image int one = (Integer) arraylist.get(i); pDraw.remove(one); final JLabel label; pDraw.add(label,one); }

  • How build my own Application Setting

    - by adisembiring
    I want to build a ApplicationSetting for my application. The ApplicationSetting can be stored in a properties file or in a database table. The settings are stored in key-value pairs. E.g. ftp.host = blade ftp.username = dummy ftp.pass = pass content.row_pagination = 20 content.title = How to train your dragon. I have designed it as follows: Application settings reader: interface IApplicationSettingReader { read(); } DatabaseApplicationSettingReader { dao appSettingDao; AppSettings read() { List<AppSettingEntity> listEntity = appSettingsDao.findAll(); Map<String, String> map = new HaspMap<String, String>(); foreach (AppSettingEntity entity : listEntity) { map.put(entity.getConfigName(), entity.getConfigValue()); } return new AppSettings(map); } } DatabaseApplicationSettingReader { dao appSettingDao; AppSettings read() { //read from some properties file return new AppSettings(map); } } Application settings class: AppSettings { private static AppSettings instance; private Map map; Public AppSettings(Map map) { this.map = map; } public static AppSettings getInstance() { if (instance == null) { throw new RuntimeException("Object not configure yet"); } return instance; } public static configure(IApplicationSettingReader reader) { instance = reader.read(); } public String getFtpSetting(String param) { return map.get("ftp." + param); } public String getContentSetting(String param) { return map.get("content." + param); } } Test class: AppSettingsTest { IApplicationSettingReader reader; @Before public void setUp() throws Exception { reader = new DatabaseApplicationSettingReader(); } @Test public void getContentSetting_should_get_content_title() { AppSettings.configure(reader); Instance settings = AppSettings.getInstance(); String title = settings.getContentSetting("title"); assertNotNull(title); Sysout(title); } } My questions are: Can you give your opinion about my code, is there something wrong? I configure my application setting once, while the application start, I configure the application setting with appropriate reader (DbReader or PropertiesReader), I make it singleton. The problem is, when some user edit the database or file directly to database or file, I can't get the changed values. Now, I want to implement something like ApplicationSettingChangeListener. So if the data changes, I will refresh my application settings. Do you have any suggestions how this can be implemented?

  • Get Cell RSSI(Network Signal Strength) on Android 1.5

    - by Brandon
    Is there any way to retrieve the current cellular Signal Strength (RSSI) on Android 1.5? I know there's a way to listen for signal strength updates through the TelephonyManager, but this seems to only give a "state," not a numeric value. Is using the RSSI field on a neighboring cell fairly accurate? I'm guessing not, but I'm running out of ideas.

  • Converting a string to an integer (Android)

    - by James Rattray
    I'm not 100% on how to do this so i'm asking... May seem stupid but... How do I convert a string into an integer? Background info: I have a textbox I have the user enter a number into... it then: EditText et = (EditText) findViewById(R.id.entry1); String hello = et.getText().toString(); gets the string 'hello' Now I want to convert it to a integer so I can get the number they typed in -will be used later on in code... Is there a way to get the edittext to a integer? -That would skip the middle man... If not, string to integer will be just fine... Thanks alot, James

  • Hibernate generate POJOs with Equals

    - by jschoen
    We are using hibernate in a new project where we use the hibernate.reveng.xml to create our *.hbm.xml files and POJOs after that. We want to have equals methods in each of our POJOs. I found that you can use <meta attribute="use-in-equals">true</meta> in your hbm files to mark which properties to use in the equals. But this would mean editing alot of files, and then re-editing the files again in the future if/when we modify tables or columns in our DB. So I was wondering if there is a way to place which properties to use in the equals method for each pojo(table) in the hibernate.reveng.xml file?

  • Is it safe to reuse javax.xml.ws.Service objects

    - by Noel Ang
    I have JAX-WS style web service client that was auto-generated with the NetBeans IDE. The generated proxy factory (extends javax.xml.ws.Service) delegates proxy creation to the various Service.getPort methods. The application that I am maintaining instantiates the factory and obtains a proxy each time it calls the targetted service. Creating the new proxy factory instances repeatedly has been shown to be expensive, given that the WSDL documentation supplied to the factory constructor, an HTTP URI, is re-retrieved for each instantiation. We had success in improving the performance by caching the WSDL. But this has ugly maintenance and packaging implications for us. I would like to explore the suitability of caching the proxy factory itself. Is it safe, e.g., can two different client classes, executing on the same JVM and targetting the same web service, safely use the same factory to obtain distinct proxy objects (or a shared, reentrant one)? I've been unable to find guidance from either the JAX-WS specification nor the javax.xml.ws API documentation. The factory-proxy multiplicity is unclear to me. Having Service.getPort rather than Service.createPort does not inspire confidence.

  • custom tag 'cannot be resolved to a type'

    - by lotus99t
    I have a custom tag, packaged into a library jar that is included in my web apps war file. I get the following error: An error occurred at line: 66 in the jsp file: /WEB-INF/jsp/portlet/portfolio/operations/operationsInfo.jsp org.apache.jsp.tag.meta.form.WidgetFactory_tag cannot be resolved to a type 63: <c:forEach var="fldCfg" items="${config.page.fields}" > 64: <tr> 65: <td><form:Label fld="${fldCfg}"/></td> 66: <td><form:WidgetFactory fld="${fldCfg}" decodesMap="${decodesMap}" command="${operationsInfoBean}" dateFormat="${preferredDateFormat}"/></td> 67: </tr> 68: </c:forEach> 69: </table> But it doesn't seem to complain about Label which is in the same taglib. I've confirmed that the jar is in the war and that the tag file is in the jar and the that the TLD (in META-INF) expressly defines 'WidgetFactory' Why am I getting this error?

  • B-Tree Revision

    - by stan
    Hi, If we are looking for line intersections (horizontal and vertical lines only) and we have n lines with half of them vertical and no intersections then Sorting the list of line end points on y value will take N log N using mergesort Each insert delete and search of our data structue (assuming its a b-tree) will be < log n so the total search time will be N log N What am i missing here, if the time to sort using mergesort takes a time of N log N and insert and delete takes a time of < log n are we dropping the constant factor to give an overal time of N log N. If not then how comes < log n goes missing in total ONotation run time? Thanks

  • Android - Making an activity display different things depending on what is clicked

    - by user3682017
    I have a listview that is populated by an arraylist of classes. public void populateThingsList(){ listExample.add(new Example("Example name", 1, "Example detail 1", "Example detail 2", R.drawable.1_icon, "Example detail 3")); listExample.add(new Example("Example name1", 2, "Example detail 1", "Example detail 2", R.drawable.2_icon, "Example detail 3")); listExample.add(new Example("Example name2", 3, "Example detail 1", "Example detail 2", R.drawable.3_icon, "Example detail 3")); listExample.add(new Example("Example name3", 4, "Example detail 1", "Example detail 2", R.drawable.4_icon, "Example detail 3")); listExample.add(new Example("Example name4", 5, "Example detail 1", "Example detail 2", R.drawable.5_icon, "Example detail 3")); listExample.add(new Example("Example name5", 6, "Example detail 1", "Example detail 2", R.drawable.6_icon, "Example detail 3")); listExample.add(new Example("Example name6", 7, "Example detail 1", "Example detail 2", R.drawable.7_icon, "Example detail 3")); listExample.add(new Example("Example name7", 8, "Example detail 1", "Example detail 2", R.drawable.8_icon, "Example detail 3")); listExample.add(new Example("Example name8", 9, "Example detail 1", "Example detail 2", R.drawable.9_icon, "Example detail 3")); listExample.add(new Example("Example name9", 10, "Example detail 1", "Example detail 2", R.drawable.10_icon, "Example detail 3")); } This is the code for the clicklistener. ListView list = (ListView) findViewById(R.id.exampleListView); list.setOnItemClickListener(new AdapterView.OnItemClickListener() { @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { Example clickedexample = listExample.get(position); startActivity(new Intent("com.example.app.EXAMPLEACTIVITY")); } } Is there any way I can get the information from clickedExample and set the textViews and imageView in ExampleActivity depending on which one was clicked?

  • XML strings in JAXB

    - by OOO
    I have a JPA entity class mimicking a table. Something like this: @XmlType(name="MyClassElementType") public class MyClass { String name; String xmlDesc; public MyClass() {} @XmlElement String getName() { return name; } void setName(String name) { this.name = name; } @XmlElement String getXmlDesc() { return xmlDesc; } void setXmlDesc(String xmlDesc) { this.xmlDesc = xmlDesc; } } In a Jersey REST get call I'm trying to return this class: @Get @Produces("application/xml") public MyClass get() { return myClass; } Now I'm expecting the already xml string(xmlStr) to be returned as is, but Jersey/JAXB escapes it... So anyway around this?

  • Oauth callback problem

    - by yogsma
    I am using OAuth with google data api. We have a portal only for authorized users. So when users are logged in and if they are accessing calendar page, they will be asked if they want to sync their calendars with google calendar. If yes, they will be redirected for authentication. Once user has granted access, google appends OAuth_Token to the callback URL. the callback URL was that of the page of calendar in portal. This url has its query string options encrypted. But when the redirection happens , it takes back to login page of url. url is like http://aaa.xyz.com/(encrypted part of query string) and after oauth_token is authorized, this url becomes http://aaa.xyz.com/(encrypted part of query string)&oauth_token. So the user sees the login page after redirection instead of original page. How should I handle this in code.

  • Sending Email with attachment, sends a blank file.

    I am using this code: File myDir = new File(getApplicationContext().getFilesDir().getAbsolutePath()); try { Log.i("CSV Testing ", "CSV file creating"); FileWriter fw = new FileWriter(myDir + "/myfile.csv"); // // write data to file // Log.i("CSV Testing ", "CSV file created and your data has been saved"); // Process for sending email with CSV file File CSVFile = new File(myDir,"myfile.csv"); if(CSVFile.exists()) { Log.i("CSV FILE", "CSV file exists"); } else { Log.i("CSV FILE", "CSV file not exists"); } Log.i("SEND EMAIL TESTING", "Email sending"); Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND); emailIntent.setType("text/csv"); emailIntent .putExtra(android.content.Intent.EXTRA_EMAIL, new String[]{"myemailid"}); emailIntent .putExtra(android.content.Intent.EXTRA_SUBJECT, "my subject"); emailIntent .putExtra(android.content.Intent.EXTRA_TEXT, "_____________\n Regards \n Pankaj \n ____________ "); emailIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse("file://" + CSVFile.getAbsolutePath())); emailIntent.setType("message/rfc822"); // Shows all application that supports SEND activity try { startActivity(Intent.createChooser(emailIntent, "Send mail...")); } catch (android.content.ActivityNotFoundException ex) { showMSG("There are no email clients installed."); } Log.i("SEND EMAIL TESTING", "Email sent"); } catch (FileNotFoundException e) { Log.i("ExportCSV Exception", e.toString()); } catch (IOException e) { Log.i("ExportCSV Exception", e.toString()); } But it sends myfile.csv as a blank file. I checked it from file explorer, where myfile.csv is not blank and contains right data. How can I solve this?

  • Playing around with Eclipse features - Project files are now hidden?

    - by Daddy Warbox
    I don't even remember how, but somehow I managed to make all of my project's source files hidden in Eclipse's Package and Project Explorer panels. Go figure. 'Show Filtered Children (alt+click)' temporarily reveals the files, and only in Package Explorer can I double-click to reopen them from this view. They go back into hiding after I select another item, though. Plus, now I'm getting other annoyances, such as all of the folded non-hidden trees altogether expanding when I click on any item, and the entire file folder tree of my project now being shown in these panels (including my .svn subversion folders... which shouldn't be any of Eclipse's business, presently). Long story short, my Package/Project Explorers' just blew up on me, and I want to know how to fix this. Thanks in advance. P.S. What's a good guide I can use to learn my way around this silly contraption, anyway?
