  • Spring MVC 3.0 Rest problem

    - by Gidogeek
    Hi Guys, I'm trying out Spring MVC 3.0 for the first time and like to make it RESTfull. This is my controller: @Controller @RequestMapping(value = "/product") @SessionAttributes("product") public class ProductController { @Autowired private ProductService productService; public void setProductValidator(ProductValidator productValidator, ProductService productService) { this.productService = productService; } @RequestMapping(method = RequestMethod.GET) public Product create() { //model.addAttribute(new Product()); return new Product(); } @RequestMapping(method = RequestMethod.POST) public String create(@Valid Product product, BindingResult result) { if (result.hasErrors()) { return "product/create"; } productService.add(product); return "redirect:/product/show/" + product.getId(); } @RequestMapping(value = "/show/{id}", method = RequestMethod.GET) public Product show(@PathVariable int id) { Product product = productService.getProductWithID(id); if (product == null) { //throw new ResourceNotFoundException(id); } return product; } @RequestMapping(method = RequestMethod.GET) public List<Product> list() { return productService.getProducts(); } } I have 2 questions about this. I'm a believer in Convention over Configuration and therefor my views are in jsp/product/ folder and are called create.jsp , list.jsp and show.jsp this works relatively well until I add the @PathVariable attribute. When I hit root/product/show/1 I get the following error: ../jsp/product/show/1.jsp" not found how do I tell this method to use the show.jsp view ? If I don't add the RequestMapping on class level my show method will be mapped to root/show instead of root/owner/show how do I solve this ? I'd like to avoid using the class level RequestMapping.

  • Guice expert question

    - by Roman
    Hi All I am wondering if someone would be such an expert in guice that he even would know how to implement that : I have an injection annotation (@ConfParam)with some parameters , like that : class TestClass { private final int intValue; @Inject public TestClass(@ConfParam(section = "test1", key = "1") int intValue{ this.intValue = intValue; } public int getIntValue() { return intValue; } } The ConfParam is my custom annotation. Now , when the injection value is requested , I would like guice to create a dynamic binding, to resolve the value. For that binding I will need the parameters inside the annotation. Some example could be , I will have to look in the database in some table where the section is ? and the key is ?. All the trouble is that the data is not available when the injector is created and could be also be added at runtime. Ps. I static solution is easy. ( just have a look at the Names class)

  • Correct handling of return data

    - by Serhiy
    Hello, I have a question related to correct handling of returns of the DAO library I'm writing for one project. This library probably is going to be used by another people and I want to do it correctly. So I would like to know, how I should deal with return statements of the functions of my DAO. Example 1 I have function to getCustomer which should return String. In case query doesn't return any result should I return null, empty string or throw some kind of Exception? Example 2 I have function getCutomerList which return ArrayList. In case query doesn't return any result should I return null, empty ArrayList or throw some Exception? Example 3 Some sql exception was detected, what should I do: throw exception or do try..catch of the block where it can occur? What is the "good" practice or "best" practice to apply in my case? Thanks on advance, Serhiy.

  • Current tasks count at Appengine Task Queue

    - by splix
    Are there any ways to get count of current unfinished tasks at Google Appengine development server? I need it for making my integration test. I found a way to get this when running it local (just in mem), as described at appengine docs. But when i'm running it as a standalone server, from maven, this doesn't work. Just because library appengine-testing conflicts with Appengine SDK classes, and i can't use those classes together, when running sdk dev server.

  • dynamic 404.jsp using struts

    - by Kapsh
    I would like to display an intelligent 404 page with some application data. Currently, there is a 'dumb' jsp, so I just forward to the view and I am done with it. But now I guess I really need to forward to an action so that I can set some more data to display on the error.jsp. How do I do it through configuration via struts-config? I need congifuration because I do not want to touch any individual files that might be forwarding to the existing view. I tried doing the fol, but I get an error and I dont see anything in the log. So currently, <forward name="ErrorView" path="/Error404.jsp" type="org.apache.struts.action.ActionForward"> </forward> What I want: <forward name="ErrorView" path="/errorAction.do" type="org.apache.struts.action.ActionForward"> </forward>

  • Long To XMLGregorianCalendar and back to Long

    - by JD.
    I am trying to convert from millisecond time stamp to XMLGregorianCalendar and back, but I seem to be getting wrong results. Am I doing something wrong? It seems I am gaining days. // Time stamp 01-Jan-0001 00:00:00.000 Long ts = -62135740800000L; System.out.println(ts); System.out.println(new Date(ts)); // Sat Jan 01 00:00:00 PST 1 .. Cool! // to Gregorian Calendar GregorianCalendar gc = new GregorianCalendar(); gc.setTimeInMillis(ts); // to XML Gregorian Calendar XMLGregorianCalendar xc = DatatypeFactory.newInstance().newXMLGregorianCalendar(gc); // back to GC GregorianCalendar gc2 = xc.toGregorianCalendar(); // to Timestamp Long newTs = gc2.getTimeInMillis(); System.out.println(newTs); // -62135568000000 .. uh? System.out.println(new Date(newTs)); // Mon Jan 03 00:00:00 PST 1 .. where did the extra days come from?

  • Manage groups of build configurations in Hudson

    - by Lóránt Pintér
    I'm using Hudson to build my application. I have several branches that come and go. Whenever there's a new branch, I have to set up the following builds for it: a continuous build that runs after every change in SVN a nightly build a nightly site generation (I'm using Maven under the hood) and a weekly integration build for some branches currently this means I need to copy four template configurations and set them up with the branch URL. I don't like this for two reasons: It's redundant, so modifying something is error-prone and takes a lot of time. I need four full checkouts of the product per branch on every build slave, plus four separate private Maven repository, not to mention the built artifacts. This is a lot of space wasted. What I'd like instead is to have one workspace and one configuration for allthese builds. Is this possible with Hudson?

  • Can I find out which thread is running using Eclipse?

    - by Roman
    I close my application by pressing a "Close" button. But in the Eclipse I see a red square indicating that something is still running. When I press this red square, I kill my application completely. Is it possible to find out what is still running (which method, which loop) using Eclipse? P.S. I am a newbie. So, it would be nice to have a simple solution. I also might not understand your answer if you use "technical" words which I do not know.

  • How to set attribs in GWT?

    - by Jonas Byström
    I'm not getting any effect out of DOM.setElementAttribute, am I doing something wrong? class MyListBox extends com.google.gwt.user.client.ui.ListBox { .... protected void setHoverAutoWidth() { addDomHandler(new MouseOverHandler() { public void onMouseOver(MouseOverEvent event) { DOM.setElementAttribute(getElement(), "width", "auto"); } }, MouseOverEvent.getType()); addDomHandler(new BlurHandler(){ public void onBlur(BlurEvent event) { DOM.setElementAttribute(getElement(), "width", "100px"); } }, BlurEvent.getType()); } } (I know there are less hacky ways to change the width than to set the style attribute directly, but I don't care about css right now.) Edit: Oops, just realized that width does not change the style width, just adds a width attribute to the tag (which explains why nothing happens). Any suggestions on how to modify the style are still welcome!

    I want to read in a file and create a duplicate of the file but my code only write the last line in the file. How do I make so that whenever I call write(), it writes to a new line. I want to create a new file for the duplicate so I can't add true to FileWriter constructor. This is my code: //Create file reader BufferedReader iReader = new BufferedReader(new FileReader(args[1])); //Create file writer BufferedWriter oWriter = new BufferedWriter(new FileWriter(args[2], true)); String strLine; //reading file int iterate = 0; while((strLine = iReader.readLine()) != null) { instructions[iterate] = strLine; } //creating duplicate for(int i = 0; i < instructions.length; i++) { if(instructions[i] != null) { oWriter.write(instructions[i]); oWriter.newLine(); } else { break; } } try { iReader.close(); oWriter.close(); } catch (IOException e) { e.printStackTrace(); }

  • hibernate annotation bi-directional mapping

    - by smithystar
    I'm building a web application using Spring framework and Hibernate with annotation and get stuck with a simple mapping between two entities. I'm trying to create a many-to-many relationship between User and Course. I followed one of the Hibernate tutorials and my implementation is as follows: User class: @Entity @Table(name="USER") public class User { private Long id; private String email; private String password; private Set<Course> courses = new HashSet<Course>(0); @Id @GeneratedValue @Column(name="USER_ID") public Long getId() { return id; } public void setId(Long id) { this.id = id; } @Column(name="USER_EMAIL") public String getEmail() { return email; } public void setEmail(String email) { this.email = email; } @Column(name="USER_PASSWORD") public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } @ManyToMany(cascade = CascadeType.ALL) @JoinTable(name = "USER_COURSE", joinColumns = { @JoinColumn(name = "USER_ID") }, inverseJoinColumns = { @JoinColumn(name = "COURSE_ID") }) public Set<Course> getCourses() { return courses; } public void setCourses(Set<Course> courses) { this.courses = courses; } } Course class: @Entity @Table(name="COURSE") public class Course { private Long id; private String name; @Id @GeneratedValue @Column(name="COURSE_ID") public Long getId() { return id; } public void setId(Long id) { this.id = id; } @Column(name="NAME") public String getName() { return name; } public void setName(String name) { this.name = name; } } The problem is that this implementation only allows me to go one way user.getCourses() What do I need to change, so I can go in both directions? user.getCourses() course.getUsers() Any help would be appreciated.
