    I'm writing web-app using MySQL version 5.1.45, Tomcat 5.5.28 and Hibernate 3 When I'm trying to save string that contains non-latin characters (for example ??????) error occurs: 1589 [main] WARN org.hibernate.util.JDBCExceptionReporter - SQL Error: 1366, SQLState: HY000 1589 [main] ERROR org.hibernate.util.JDBCExceptionReporter - Incorrect string value: '\xD0\xA3\xD0\xBF\xD1\x8F...' for column 'name' at row 1 Hibernate connection settings <property name="connection.driver_class">com.mysql.jdbc.Driver</property> <property name="connection.url">jdbc:mysql://localhost/E2012?characterEncoding=UTF8&amp;useUnicode=true</property> <property name="connection.username">***</property> <property name="connection.password">***</property> <property name="hibernate.connection.charSet">UTF8</property> MySQL config My.cnf [client] default-character-set=utf8 [mysqld] default-character-set=utf8 Even query set name utf-8 doesn't resolve problem Thanks for help!

  • How to create a JAX-RS service where the sub-resource @Path doesn't have a leading slash

    - by Matt
    I've created a JAX-RS service (MyService) that has a number of sub resources, each of which is a subclass of MySubResource. The sub resource class being chosen is picked based on the parameters given in the MyService path, for example: @Path("/") @Provides({"text/html", "text/xml"}) public class MyResource { @Path("people/{id}") public MySubResource getPeople(@PathParam("id") String id) { return new MyPeopleSubResource(id); } @Path("places/{id}") public MySubResource getPlaces(@PathParam("id") String id) { return new MyPlacesSubResource(id); } } where MyPlacesSubResource and MyPeopleSubResource are both sub-classes of MySubResource. MySubResource is defined as: public abstract class MySubResource { protected abstract Results getResults(); @GET public Results get() { return getResults(); } @GET @Path("xml") public Response getXml() { return Response.ok(getResults(), MediaType.TEXT_XML_TYPE).build(); } @GET @Path("html") public Response getHtml() { return Response.ok(getResults(), MediaType.TEXT_HTML_TYPE).build(); } } Results is processed by corresponding MessageBodyWriters depending on the mimetype of the response. While this works it results in paths like /people/Bob/html or /people/Bob/xml where what I really want is /people/Bob.html or /people/Bob.xml Does anybody know how to accomplish what I want to do?

  • Invalid method declaration, return type required

    - by Brett Steen
    I am getting an error at public Rectangle(double width, double height){ saying that it's an invalid method declaration, return type required. I'm not sure how to fix it. These are also my instructions for my assignment: Write a super class encapsulating a rectangle. A rectangle has two attributes representing the width and the height of the rectangle. It has methods returning the perimeter and the area of the rectangle. This class has a subclass, encapsulating a parallelepiped, or box. A parallelepiped has a rectangle as its base, and another attribute, its length. It has two methods that calculate and return its area and volume. `public class Rectangle1 { private double width; private double height; public Rectangle1(){ } public Rectangle(double width, double height){ this.width = width; this.height = height; } public double getWidth(){ return width; } public void setWidth(double width) { this.width = width; } public double getHeight(){ return height; } public void setHeight(double height){ this.height = height; } public double getArea(){ return width * height; } public double getPerimeter(){ return 2 * (width + height); } } public class TestRectangle { public static void main(String[] args) { Rectangle1 rectangle = new Rectangle1(2,4); System.out.println("\nA rectangle " + rectangle.toString()); System.out.println("The area is " + rectangle.getArea()); System.out.println("The perimeter is " + rectangle.getPerimeter()); } }`

  • Do Blob properties on entities affect query performance?

    - by Jaroslav Záruba
    Hello I'm trying to make my mind on whether to store a binary representation of an entity as its Blob property, or whether I better keep the blobs in some separate 'wrapping' class. Possible impact on memory heap and/or a query execution time are my concerns in the first case, complexity votes against the other one. I know Blobs are not indexed, i.e. index size is not what I'm worrying about. Also I assume for blobs Datastore puts defaultFetchGroup to false, but does it mean that blobs don't make a difference in queries? Regards J. Záruba

    My source code: final Thread t = new Thread() { public void run() { Looper.prepare(); HttpClient client = new DefaultHttpClient(); HttpConnectionParams.setConnectionTimeout(client.getParams(), 10000); HttpResponse response; JSONObject obj = new JSONObject(); try { HttpPost post = new HttpPost("http://pc.dyndns-office.com/mobile.asp"); obj.put("Model", ReadIn1); obj.put("Product", ReadIn2); obj.put("Manufacturer", ReadIn3); obj.put("RELEASE", ReadIn4); obj.put("SERIAL", ReadIn5); obj.put("ID", ReadIn6); obj.put("ANDROID_ID", ReadIn7); obj.put("Language", ReadIn8); obj.put("BOARD", ReadIn9); obj.put("BOOTLOADER", ReadIn10); obj.put("BRAND", ReadIn11); obj.put("CPU_API", ReadIn12); obj.put("DISPLAY", ReadIn13); obj.put("FINGERPRINT", ReadIn14); obj.put("HARDWARE", ReadIn15); obj.put("UUID", ReadIn16); StringEntity se = new StringEntity(obj.toString()); se.setContentType(new BasicHeader(HTTP.CONTENT_TYPE, "application/json")); post.setEntity(se); post.setHeader("host", "http://pc.dyndns-office.com/mobile.asp"); response = client.execute(post); if (response != null) { InputStream in = response.getEntity().getContent(); } } catch (Exception e) { e.printStackTrace(); } Looper.loop(); } }; t.start(); } } i want to send an Json object to a Website. As far as I can see, I set the header, but still I get this exception, can someone help me? (I'm using Android-Studio) __ Edit: i don't get any exceptions anymore, but still i do not receive the json packet. When i manually call the website i get a log file entry. Does anyone know, what's wrong? Edit2: When i debug i get as response "HTTP/1.1 400 bad request" i'm sure its not an permission problem. Any ideas?

  • How to develop a Nightly Builder

    - by allenzzzxd
    Hello, I was told to create a tool like a Nightly Builder for a JUnit project. It's a client-server project with oracle database.The tests are based on QTP. Also there is a test interface written on C#. The tester can click on the interface to choose which tests to run and get a report from each test. So I have to make this procedure automated. So what tools should I use? Thanks in advance Best regards

    - by Roman
    Why is the setContextClassLoader() method placed on thread ? What different thread have different classloaders? The question is what if i extended a classloader , loaded there some new classes. to the my custom classloader. Now , I want it to be the context classloader , so I call the method (Thread.currentThread().setContextClassLoader(loader)). Are these new classes awailable only in the context of the current Thread ? ( or how does it work ?) Thanks

  • in a J2EE application when does a listener get called?

    - by josh
    I have a J2EE app and it has a listener in web.xml. Listener contains a method called contextInitialized I want to know when does contextInitialized actually get called? From my reading I understand that it gets called when deploying the application. Can there be situations/scenario's where it could be called after the application has been deployed? Say that I am in a Clustered GlassFish app server environment. Could it be called after the application has been deployed?

  • Reducing the pain writing integration and system tests

    - by mdma
    I would like to make integration tests and system tests for my applications but producing good integration and system tests have often needed so much effort that I have not bothered. The few times I tried, I wrote custom, application-specific test harnesses, which felt like re-inventing the wheel each time. I wonder if this is the wrong approach. Is there a "standard" approach to integration and full system testing? EDIT: To clarify, it's automated tests, for desktop and web applications. Ideally a complete test suite that exercises the full functionality of the application.

  • JMX - MBean automated registration on application deployment

    - by Gadi
    Hi All, I need some direction with JMX and J2EE. I am aware (after few weeks of research) that the JMX specification is missing as far as deployment is concerned. There are few vendor specific implementations for what I am looking for but none are cross vendor. I would like to automate the deployment of MBeans and registration with the Server. I need the server to load and register my MBeand when the application is deployed and remove when the application is un-deployed. I develop with: NetBean 6.7.1, GlassFish 2.1, J2EE5, EJB3 More specific, I need a way to manage timer service runs. My application need to run different archiving agents and batch reporting. I was hoping the JMX will give me remote access to create and manage the timer services and enable the user to create his own schedule. If the JMX is auto registered on application deployment the user can immediately connect and manage the schedule. On the other hand, how can an EJB connect/access an MBean? Many thanks in advance. Gadi.

  • 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?

  • 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); }

  • Ask Basic Configurator in Apache Commong Log

    - by adisembiring
    I use log4j as logger for my web application. in log4j, I can set the level log in log4j properties or log4j.xml. in log4j, we instance logger as follows: static Logger logger = Logger.getLogger(SomeClass.class); I init log4j basic configurator in a servlet file using init method. But, I usually test application using JUnit, So I init the basic configurator in setup method. after that, I test the application, and I can see the log. Because I deployed, the web in websphere. I change all of logging instance become: private Log log = LogFactory.getLog(Foo.class); I don't know how to load basic configurator using ACL. so I can't control debug level to my JUnit test. do you have any suggestion, without changing static Logger logger = Logger.getLogger(SomeClass.class); become static Logger logger = Logger.getLogger(SomeClass.class);

  • copy or clone a HSSFWorkbook

    - by Fortega
    Hi, Currently I am doing the following in a loop (at least 300 times): - create a HSSFWorkbook from a template file - add some values to specific cells in the workbook - save the workbook as a new excel file The first line takes about 70% of the time (reading excel file). What I would like to do is to take this out of the loop, and read the file only once. In the loop, I would like to copy or clone the template HSSFWorkbook. However, I can't find anything about copying/cloning a HSSFWorkbook. Did some of you do this before? Any tips?

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

    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 find the first declaring method for a reference method

    - by Oliver Gierke
    Suppose you have a generic interface and an implementation: public interface MyInterface<T> { void foo(T param); } public class MyImplementation<T> implements MyInterface<T> { void foo(T param) { } } These two types are frework types. In the next step I want allow users to extend that interface as well as redeclare foo(T param) to maybe equip it with further annotations. public interface MyExtendedInterface extends MyInterface<Bar> { @Override void foo(Bar param); // Further declared methods } I create an AOP proxy for the extended interface and intercept especially the calls to furtherly declared methods. As foo(…) is no redeclared in MyExtendedInterface I cannot execute it by simply invoking MethodInvocation.proceed() as the instance of MyImplementation only implements MyInterface.foo(…) and not MyExtendedInterface.foo(…). So is there a way to get access to the method that declared a method initially? Regarding this example is there a way to find out that foo(Bar param) was declared in MyInterface originally and get access to the accoriding Method instance? I already tried to scan base class methods to match by name and parameter types but that doesn't work out as generics pop in and MyImplementation.getMethod("foo", Bar.class) obviously throws a NoSuchMethodException. I already know that MyExtendedInterface types MyInterface to Bar. So If I could create some kind of "typed view" on MyImplementation my math algorithm could work out actually.

  • custom tag 'cannot be resolved to a type'

    I have a custom tag, packaged into a library jar that is included in my web apps war file.

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?
