requestfactory

问题 I'm using gwt-maven-plugin to manage a GWT project. I use the gwt:run goal all the time to run locally in "dev mode" for testing. I now want to compile my project into a war for deployment on Tomcat. When I run gwt:compile , however, I get compile errors that indicate a classpath configuration issue. An example: Finding entry point classes [ERROR] Errors in 'shared.MyClass.java' [ERROR] Line 4: The import server.model.MyObject cannot be resolved Any ideas? Do I need to manually add the server

问题 Does anyone have a working example of using the new GWT constructs for RequestFactory with a SmartGWT DataSource for databound widgets ? If possible I would like to make a generic data service that contains methods for listAll , getByExample , getByPrimaryKey etc. I beleibe it should be possible ??? If using RequestFactory would it make sense to ditch the datasource altogether and work directly with the widget fields ? Cheers, Andy 回答1: http://forums.smartclient.com/showthread.php?t=10850

问题 I compiled the version in svn tagged as gwt2.4rc. Now there are a couple of more libraries than I had the last time. Are the any instructions on which library is needed for what? I tried it with only the standard libraries (servlet, servlet-deps, user) but I get the following error when a requestfactory call is made: java.lang.NoSuchMethodError: com.google.gwt.core.client.impl.WeakMapping.setWeak(Ljava/lang/ Object;Ljava/lang/String;Ljava/lang/Object;) I tried declaring the requestfactory

问题 In Google's RequestFactory tutorials, they recommend putting my persistence logic (in my case, Hibernate) inside the Entity classes. Then they pose the question: "What if you don't want to implement persistence code in an entity itself?" and proceed to explain an alternate method. My question: which is better, putting persistence logic inside the Entity class, or keeping all persistence logic in a separate class? Any info is appreciated, thanks. -tjw 回答1: Putting the persistence code in an

问题 I'm using IDEA 117.216 It would be great if CrazyCoder sees this question :) How do you guys reference another module so GWT compiler sees it ? When I say module I mean module in IntelliJ IDEA's terminology. Here is my situation. I have midside project (GAE + GWT + RequestFactory). Now I created Android module in my project. The idea is that it will use C2DM and talk to the server via RequestFactory (RF). So naturally I created 3rd module within my project and moved all RF proxies and

问题 I'm new to RequestFactory but with generous help of Thomas Broyer and after reviewing documents below it's getting much better :) Getting Started with RequestFactory Request Factory Moving Parts RequestFactory changes in GWT 2.4 But could you please explain why Locator<>.find() is being called so unnecessarily (in my opinion) often ? In my sample project I have two entities Organization and Person that maintain parent-child relationship. When I fetch Organization Objectify automatically
