问题 I am facing this error while running my GWT application. I have these jar files in my classpath: slf4j-api & slf4j-log4j12 Any idea what could be the reason? 回答1: This problem is due to a change in slf4j-log4j12 jar. From version 1.5.6 it doesn't allow to access the field org.slf4j.impl.StaticLoggerBinder.SINGLETON. To resolve it, use the newest jars (or at least version 1.5.6 onward) for both slf4j-api & slf4j-log4j12. <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api<

问题 I have a GWT Project containing some GWT modules that I would like to have NO entry point, functioning as libraries for other modules WITH entry points. The GWT 'entry point' modules compile fine with the "GWT Compile Project" option in Eclipse if I choose not to compile the GWT 'library' modules with them. They also run fine. When I choose to deploy my project to the Google App Engine with the "Deploy App Engine Project" option, all modules will get compiled and this process gets stuck on

问题 I want to use method level security on my GWT application. I'm trying to use Spring Security 3.1, as I found a working example here, but it doesn't use form-login. After reading this answer the first method call successfully obtains the SecurityContext, but then clears it before the next call: [org.springframework.security.web.context.HttpSessionSecurityContextRepository] - Obtained a valid SecurityContext from SPRING_SECURITY_CONTEXT: 'org.springframework.security.core.context

问题 I'm getting this error after running my application. There were no errors during compilation. Also, thr's no other application running.

问题 i know there is a lot of questions on this already but I still didn't seem to find a definitive answer. What i'm looking to do is have users be remembered after they login for say 2 weeks or until they log out. Below is what I think should be happening and I was wondering if anyone with a bit more experience could tell me if i'm right or wrong. User logs in for the first time. An RPC call to the server returns a 'UserInfo' object which includes with it a new sessionID. Aka on the server this

问题 I am trying to install the gwt-maven-plugin for Eclipse Indigo 3.7.2 (running on Ubuntu), following the instructions here: http://uptick.com.au/content/getting-started-gwt-maven-and-eclipse However, when I get to the step to install "Maven Integration for Eclipse WTP", I get the following error: Cannot complete the install because one or more required items could not be found.

问题 I would like to use GWT to read and parse local csv file. EDIT: Local file here means client file. I know I can use HTML5 with javascript to achieve that, but I would like to use GWT to do it. One way of doing it is by using JavaScript Native Interface (JSNI), however I think it beats the purpose of using GWT. Another way of doing this would be upload the file to server, and send it back as a json. But I feel it's not the best way of doing it. Please advise. Thanks. EDIT: I intend to design a

问题 I realize that GWt doesn't compile the classes not in the Client package. But what is the importance of the shared package? What are the classes that I need to put in this package? 回答1: What are the classes that I need to put in this package? Any logic or data types that are used by both the client and the server. This will save you from duplicating code across both sides, and potentially keep the logic and data types consistent . 来源： https://stackoverflow.com/questions/3356100/importance-of

问题 I'm trying to figure out how to serialize a list using AutoBean in GWT, but I keep getting a Null Pointer Exception. Here's what I have: GuideCreatorFactory beanFactory = AutoBeanFactorySource.create(GuideCreatorFactory.class); List<Guide> guides = new LinkedList<Guide>(); Guide guide = new Guide(); guide.setText("this is the text"); guide.setTitle("this is the title"); guides.add(guide); GuideCreatorList<Guide> impl = new GuideCreatorListImpl(); impl.setGuides(guides); System.out.println(
