gwt-rpc

问题 I'm trying to understand the RPC functionality which GWT uses, and have followed this guide. It works perfectly OK if I follow the guide and has the call to the server in a separate class file. However when I try to have the call where the entryPoints creates it will not work. I wonder why it is like that and how to fix it? package com.async.me.client; import com.async.me.client.widgets.HelloWidget; import com.google.gwt.core.client.EntryPoint; import com.google.gwt.core.client.GWT; import

问题 In a GWT application, I have a long process that runs server side and invoked using rpc(GWT dispatcher) and I want to have a feedback to the Client as a progress bar showing messages and the total progress.

I'm interested in any solution thank you in advance for your help. 回答1: Have a look at the get progress bar in the incubator. Here is another example of someone using it.

问题 Is there an easy way to invoke a GWT RPC service endpoint directly from Java code? I mean real Java code, not Java code compiled down into javascript. I ask because we want to run performance benchmarks/stress tests against a GWT RPC interface. I would like to write the test harness in Java and run it in a JVM (as opposed to javascript running in a browser). I figure there must be a way to do this because I assume GWT Hosted mode requires such functionality. However, I can't really find any

问题 I'm new to gwt. I don't know how to start up Super Dev mode . I need the detailed explanation step by step.

问题 After upgrade from GWT 2.4.0 to 2.5.0 only one of many (many!) RPC methods is broken and I have no idea why. Here is what happens (and what does not): The program gets to async service object and calls its method. Underyling, generated by GWT proxy object exists and is called (I don't know its internals, though). The browser doesn't send any request to server (at least developer tools built into Google Chrome doesn't show anything like that happening. On the other hand... see 5.). The

问题 I am having a weird bug with GWT google visualization library wrapper, specifically AnnotatedTimeLine. Namely, I draw my chart on the initial ajax call to google visualization tools, and then I redraw it every 5 seconds using a timer. Each time it redraws, the "steps" on Y axis change their values and frequency (sometimes you will have them in more frequent intervals). Note values of graph stay exactly the same. I've included 2 screenshots to show you 2 stances it goes from. On every

问题 I have a GWT app, I'm using the MVP4G framework. I'm able to pull up my app just fine if I use HTTP. However, when I try to open it using HTTPS it does not work. My entire site works fine with the SSL certificate I have. Is there a particular configuration that I need to enable when I compile GWT? Or is there something I need to do in my apache configuration?
