问题 I have an REST server as backend, it provides a set of services, also, it uses basic authentication method for access. Now I need to create an GWT frontend,so, I need to perform http calls to the REST backend from the GWT frontend After some research I found the HttpBuilder to handle http requests to the backend, but it seem to be a pain when trying to perform cross-site requests, and also it comes with some restricions related with Safari browser. Then I found this https://developers.google

问题 I'm just not getting this: I use Gin in my java GWT app to do DI. The login screen is integrated into the full application window. After the user has logged in I want to inject the user object into other classes like GUI Presenters which I create, so I have some sort of runtime dependency I believe. How do i do that? One solution I can think of is sth like: class Presenter { @Inject Presenter(LoggedInUserFactory userFactory) { User user = userFactory.getLoggedInUser(); } } class

问题 Here is the error I am receiving. I've looked everywhere for answers and I cannot figure out why anyone else isn't running into the same issue. The error happens when I'm retrieving a Proposal object from Hibernate which has a many-to-one constraint with User_Info on two properties, author and advisor. If needed I can provide the classes and hibernate configs. Just a note, I do implement isSerializeable and have empty constructors...I really appreciate any advice or help... Starting Jetty on

问题 Is there a way to ensure the same PersistenceManager instance is used throughout the different code parts executed in the context of the same RPC request? Having to manually handle out the persistence manager instance from function to function is quite a pain: for example: private void updateItem(ItemModel listItem) throws UserNotLoggedInException { PersistenceManager pm = PMF.get().getPersistenceManager(); if (isItemIsNew(pm, listItem)) { workOnItem(pm, listItem); } workSomeMoreOnItem(pm,

问题 I am working to recreate (conceptually) a prototype I've written in Cappuccino in GWT/GXT. Cappuccino made it trivial to display an external webpage as part of the application by using a WebView.

问题 I'm working on GWT. In my application I want to add a session time out after 2 minutes when no action is performed (including mouse events). I wrote a class in which I used a GWT session object. public static boolean ValidSession(HttpSession session) { boolean aResult = true; logger.debug("Start of ValidSession"); try { if(session!=null ) { String strUserInf=""; strUserInf=(String)session.getAttribute("userInf"); logger.debug("User Inf in session is: " + strUserInf); if(strUserInf==null ||
