  • @OneToyMany property null in Entity after (second) merge

    - by iNPUTmice
    Hi, I'm using JPA (with Hibernate) and Gilead in a GWT project. On the server side I have this method and I'm calling this method twice with the same "campaign". On the second call it throws a null pointer exception in line 4 "campaign.getTextAds()" public List<WrapperTextAd> getTextAds(WrapperCampaign campaign) { campaign = em.merge(campaign); System.out.println("getting textads for "+campaign.getName()); for(WrapperTextAd textad: campaign.getTextAds()) { //do nothing } return new ArrayList<WrapperTextAd>(campaign.getTextAds()); } The code in WrapperCampaign Entity looks like this @OneToMany(mappedBy="campaign") public Set<WrapperTextAd> getTextAds() { return this.textads; }

  • Calling javascript function with arguments using JSNI

    - by jav_000
    I'm trying to integrate Mixpanel with GWT, but I have problems calling an event with a property and one value. My function to track an simple event (without values): public native void trackEvent(String eventName)/*-{ $wnd.mixpanel.track(eventName); }-*/; It works. But when I want to add some properties and values, it doesn't work properly: public native void trackComplexEvent(String eventName, String property, String value)/*-{ $wnd.mixpanel.track(eventName, {property:value}); }-*/; I have 2 problems with this: 1) Mixpanel says the property name is: "property"(yes, the name of the variable that I'm passing, not the value). 2) Mixpanel says the value is:undefined An example from mixpanel web is: mixpanel.track("Video Play", {"age": 13, "gender": "male"}); So, I guess the problem is I'm doing a wrong call or with wrong type of arguments.

  • timeline charts with rich ui

    - by Karthick R
    hi all, I have a requirement to come up with a time line chart and a few more controls on a single page[with rich ui]. I have short listed Flex, JSF[apache trinidad], html5, gwt these technologies. None of them provide timeline charts on their own. I am looking at other options such as using third party libraries. The chart should have drill down capabilities as well. Let me know if there is any specific technology that I should try. regards

  • How can I pass an object as a parameter in the google app engine RPC flow?

    - by jimmartens
    I'm building a pretty basic app, and one thing I want to do is pass an object as a parameter up through the service - async - impl instead of passing up a million separate parameters. so in async, I do something like this: import shared.Profile; ... public interface ProfileServiceAsync { public void addProfile(Profile inProf, AsyncCallback<Void> async); Now, profile is a class in com. ... .shared and I have the following in my ... .gwt.xml <source path='shared'/> That being said when I try to compile I get this error. [ERROR] Errors in 'file:/D:/projects/eclipse/workspace/.../src/com/.../client/ProfileServiceAsync.java' [ERROR] Line 11: No source code is available for type shared.Profile; did you forget to inherit a required module? Any ideas on this?

  • No response in Eclipse: File ->Import->Existing Projects into Workspace

    - by Hula
    I'm trying to import one of the GWT samples into Eclipse by following the instructions below. But when I browse to the directory containing the "Hello" sample and uncheck "Copy projects into workspace", the Finish button is grayed out, preventing me from completing the import. Any ideas why? -- Option A: Import your project into Eclipse (recommended) -- If you use Eclipse, you can simply import the generated project into Eclipse. We've tested against Eclipse 3.3 and 3.4. Later versions will likely also work, earlier versions may not. In Eclipse, go to the File menu and choose: File - Import... - Existing Projects into Workspace Browse to the directory containing this file, select "Hello". Be sure to uncheck "Copy projects into workspace" if it is checked. Click Finish.

  • How to keep statefull web clients in sync, when multiple clients are looking at the same data?

    - by Hilbrand
    In a RIA web client, created with GWT, the state is maintained in the web client, while the server is (almost) stateless (this is the preferred technique to keep the site scalable). However, if multiple users looking at the same data in their browser and one user changes something, which is send to the server and stored in the database, the other users still have the old data in their browser state. For example a tree is shown and one of the users adds/removes an item from the tree. Since there can be a lot of state in the client, what is the best technique to keep the state in the clients in sync? Are there any java frameworks that take care of this?

  • I am getting an error with a oneToMany association when using annotations with gilead for hibernate

    - by user286630
    Hello Guys I'm using Gilead to persist my entities in my GWT project, im using hibernate annotations aswell. my problem is on my onetomany association.this is my User class that holds a reference to a list of FileLocations @Entity @Table(name = "yf_user_table") public class YFUser implements Serializable { @Id @GeneratedValue(strategy = GenerationType.AUTO) @Column(name = "user_id",nullable = false) private int userId; @Column(name = "username") private String username; @Column(name = "password") private String password; @Column(name = "email") private String email; @OneToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY) @JoinColumn(name="USER_ID") private List fileLocations = new ArrayList(); This is my file location class @Entity @Table(name = "fileLocationTable") public class FileLocation implements Serializable { @Id @GeneratedValue(strategy = GenerationType.AUTO) @Column(name = "locationId", updatable = false, nullable = false) private int ieId; @Column (name = "location") private String location; @ManyToOne(fetch=FetchType.LAZY) @JoinColumn(name="USER_ID", nullable=false) private YFUser uploadedUser; When i persist this data in a normal desktop application, it works fine , creates the tables and i can add and store data to it. but when i try to persist the data in my gwt application i get errors i will show them lower. this is my ServiceImpl class that extends PersistentRemoteService. public class TestServiceImpl extends PersistentRemoteService implements TestService { public static final String SESSION_USER = "UserWithinSession"; public TestServiceImpl(){ HibernateUtil util = new HibernateUtil(); util.setSessionFactory(com.example.server.HibernateUtil .getSessionFactory()); PersistentBeanManager pbm = new PersistentBeanManager(); pbm.setPersistenceUtil(util); pbm.setProxyStore(new StatelessProxyStore()); setBeanManager(pbm); } @Override public String registerUser(String username, String password, String email) { Session session = com.example.server.HibernateUtil.getSessionFactory().getCurrentSession(); session.beginTransaction(); YFUser newUser = new YFUser(); newUser.setUsername(username);newUser.setPassword(password);newUser.setEmail(email); session.save(newUser); session.getTransaction().commit(); return "Thank you For registering "+ username; } this is the error that im am getting. the error goes away when i remove my onetoManyRelationship and builds my session factory when i put it in , it on the line of buildsessionfactory in hibernate Util that it throws this exception. my hibernate util class is ok also. this is the error java.lang.NoSuchMethodError: javax.persistence.OneToMany.orphanRemoval()Z Mar 24, 2010 10:03:22 PM org.hibernate.cfg.annotations.Version <clinit> INFO: Hibernate Annotations 3.5.0-Beta-4 Mar 24, 2010 10:03:22 PM org.hibernate.cfg.Environment <clinit> INFO: Hibernate 3.5.0-Beta-4 Mar 24, 2010 10:03:22 PM org.hibernate.cfg.Environment <clinit> INFO: hibernate.properties not found Mar 24, 2010 10:03:22 PM org.hibernate.cfg.Environment buildBytecodeProvider INFO: Bytecode provider name : javassist Mar 24, 2010 10:03:22 PM org.hibernate.cfg.Environment <clinit> INFO: using JDK 1.4 java.sql.Timestamp handling Mar 24, 2010 10:03:22 PM org.hibernate.annotations.common.Version <clinit> INFO: Hibernate Commons Annotations 3.2.0-SNAPSHOT Mar 24, 2010 10:03:22 PM org.hibernate.cfg.Configuration configure INFO: configuring from resource: /hibernate.cfg.xml Mar 24, 2010 10:03:22 PM org.hibernate.cfg.Configuration getConfigurationInputStream INFO: Configuration resource: /hibernate.cfg.xml Mar 24, 2010 10:03:22 PM org.hibernate.cfg.Configuration doConfigure INFO: Configured SessionFactory: null Mar 24, 2010 10:03:22 PM org.hibernate.cfg.search.HibernateSearchEventListenerRegister enableHibernateSearch INFO: Unable to find org.hibernate.search.event.FullTextIndexEventListener on the classpath.

  • Text box loses focus when DIV is hovered

    - by Konoplianko
    Hello. I have a problem: When I enter a text into suggestion text box, popup panel appears. But when user places mouse over this popup panel with suggestions - text box loses focus. What should I do to prevent losing focus ? Example which have the same behaviour: http://demo.raibledesigns.com/gwt-autocomplete/ Thanks for any help. Update 1 SuggestionMenu which is being shown is extending MenuBar which sets focus for all menu items. void itemOver(MenuItem item, boolean focus) { if (item == null) { // Don't clear selection if the currently selected item's menu is showing. if ((selectedItem != null) && (shownChildMenu == selectedItem.getSubMenu())) { return; } } // Style the item selected when the mouse enters. selectItem(item); if (focus) { focus(); } // If child menus are being shown, or this menu is itself // a child menu, automatically show an item's child menu // when the mouse enters. if (item != null) { if ((shownChildMenu != null) || (parentMenu != null) || autoOpen) { doItemAction(item, false); } } } It's clear that i cant fix loosing focus. Now question is - how to make on pressing backspace or any key to focus on edit box? Thanks in advance

  • Passing an arbitrary JSONValue to a JSNI function

    - by Riley Lark
    I have a JSONValue in my Java that may be a JSONArray, a JSONObject, a JSONString, etc. I want to pass it to a JSNI function that can accept any of those types. If I naively write my JSNI as something like: public final native jsni(Object parameter) /*-{ doSomething(parameter); }-*/; public void useFunction(JSONValue value) { jsni(value); //Throws js exception at runtime :( } then I get a javascript exception, because GWT doesn't know how to convert the JSONValue to a JavaScriptObject (or native string / number value). My current workaround is public final native jsniForJSO(Object parameter) /*-{ doSomething(parameter); }-*/; public final native jsniForString(String parameter) /*-{ doSomething(parameter); }-*/; public final native jsniForNumber(double parameter) /*-{ doSomething(parameter); }-*/; public actuallyUseFunction(JSONValue value) { if (value.isObject()) { jsniForJSO(value.isObject().getJavaScriptObject()); } else if (value.isString()) { jsniForString(value.isString().stringValue()); } else { //etc } } This is a big burden for code maintainability, etc... especially if you have more than one parameter. Is there a way to generate these functions automatically, or get around this issue altogether? I've taken to wrapping everything in a JSONObject first, so I can definitely get a JavaScriptObject to pass to my jsni, but that's another clumsy mechanic.

  • Problem with Google Calendar API invocation at server side

    - by Raffo
    Hi guys, I have problems with the invocation of the Google Calendar API. I downloaded the library for java and I added as external JAR in eclipse the following files: gdata-core, gdata-calendar, gdata- calendar-meta, gdata-client-meta, gdata-client. Then, I created a the method as it follows: import com.google.gdata.client.calendar.CalendarService; import com.google.gdata.data.calendar.CalendarEntry; import com.google.gdata.data.calendar.CalendarFeed; import com.google.gwt.user.server.rpc.RemoteServiceServlet; public class GCalServImpl extends RemoteServiceServlet implements GCalServ { @Override public String RetrieveCalendars() { // TODO Auto-generated method stub // Create a CalenderService and authenticate try{ CalendarService myService = new CalendarService("taskR"); myService.setUserCredentials(***username***, "***password***"); // Send the request and print the response URL feedUrl = new URL("http://www.google.com/calendar/feeds/default/ allcalendars/full"); CalendarFeed resultFeed = myService.getFeed(feedUrl, CalendarFeed.class); System.out.println("Your calendars:"); System.out.println(); String s = ""; for (int i = 0; i < resultFeed.getEntries().size(); i++) { CalendarEntry entry = resultFeed.getEntries().get(i); s=entry.getTitle().getPlainText(); System.out.println("\t" + s); return s; } }catch(Exception e){ e.printStackTrace(); } return null; } I then call it from the client side doing a basic async invocation.

  • Quel avenir pour la boite à outils graphique GWT avec le désengagement progressif de Google ? Venez vous exprimer

    Lors du dernier Google IO (https://docs.google.com/presentation...1#slide=id.p18), le leader technique de GWT Ray Cromwell a annoncé le début du désengagement progressif de Google dans le développement de la boîte à outils graphique. Ce désengagement n'est pas surprenant puisque de nombreuses lacunes de la boîte à outils obligent les développeurs à compléter leur code avec des projets communautaires (Cf sondage sur les bibliothèques de composants graphiques). C'est sûremen...
