发帖数: 1223 | 1 我有一个关于GWT的问题。好像坛子里讨论的不多。在以前的一个帖子里，魔法胖子提
到“google will own your rear end”。这是个什么意思？
其实我的理想状态还是后端用jdbc或者别的persistance, 然后前端用GWT代替jsp,
这个可行吗？这个GWT前后端是怎么talk的？还需要一个spring mvc或者别的什么web
tier的东西吗？我的直觉是spring mvc 和GWT 整合应该是没戏了。谢谢了。 |

发帖数: 15201 | 2 我刚开始学gwt,想做个小应用，call一个web service(SOAP),该service会返回一个
object数组，然后我想用gwt的一些widgets在用户端来显示这个object数组包含的数据。
现在我是在gwt的server code里面调用web service，成功的取到了这个对象数组"
errorlist"。 我想把errorlist返回给client code。
我google来的近似答案是，需要把errorlist这个class放在shared目录，让client
side code可以编译到它。
但是现在的问题是，这个errorlist从WSDL生成，里面用到了org.apache.axis的一些类
。如果是把这个类文件放server端编译就毫无问题。放到shared目录后，就出错，说是：
org.apache.axis.description.ElementDesc can not be found in source packages.

I evaluated both of them a short while ago.
Ext-gwt gives me a feeling that it's more native
GWT, while SmartGWT feels like a wrapper
around SmartClient.
OTOH, Ext-gwt is either GPL or commercial, while
SmartGWT's licensing model is a little more
flexible. |

Never mind that. Just one of my poor attempts at being funny. :-)
You can still have gwt running with spring mvc, or any other http
service for that matter. Gwt supports sending standard http requests.
That's actually how I made my gwt login form communicate with spring
security's login processing service. |

I am not supposed to share the source code I have, but basically
it works like this:
1. Some GWT code submits a form to a url,
2. The url is mapped to a spring mvc handler that, well, handles
it just like any other form submission requests, prepares the model,
and forwards to a view,
3. The view renders a json response (as oppose to typical html),
4. Finally the GWT code gets the response, and parses the json.
So in the steps above, 1 and 4 are completely gwt, while 2 and 3
are spring mvc. They |

With introduction of the Dart programming language, Google has reassured the
GWT community that GWT will continue to be supported for the foreseeable
future, but also hinted at a possible rapprochement between the two Google
solutions for "structured web programming". They've also admitted however
that a number of engineers previously working on GWT are now working on Dart

发帖数: 9224 | 11 GWT我一直不看好，原因就一个: 太麻烦。而且web designer没法插手做。基本上必须
要programmer才行。
Google的东西，很多的也是他们自家的产品，对于想做软件创业的人来说，需要尽量避
免。比如说GWT, 就是个又大又笨重的东西。做点B2B的web软件，或者intranet的东西
，还行。
我觉得，做软件，要keep it simple. 软件是为了市场服务的，不是耍酷或者要多
fancy的。
话说Google，他家其实90%多的收入还是来自网络广告的。其他都是icing. Google
drive, 社交，其实都是点缀，不是他家的主营业务。
如果哪天web http protocol变化了，Google的web search的垄断会受影响。但目前，
在整个互联网基于tcp/ip, http协议的基础上，没有根本变化的情况下，Google的网页
搜索基本上是无法被撼动的。
Google不去做word啥的，其实有道理。一个公司就要focus到一件事情上，否则啥都做
不好。 |

I did an application with gwt a while ago. It was much
better experience than I had anticipated, actually.
It was quite pleasant and productive to be able to write
everything in java and in eclipse.
The caveat, of course, is that google will own your
rear end. The vendor lock-in is next to impossible to
get away from. If you are comfortable with that, gwt
is great to work with. |

发帖数: 4260 | 14 I'm sure it's not :-) but it's messy, in a lot of people's eyes.
Part of the benefit of using GWT is that you can write JS in a
language that you like better than you do JS. Being able to
use Java's compile time check is nice. Even without this, I'd
pick Python over JS any day.
And of course this package (pyjamas) is open source.
Core component in GWT is not. |

gwt前后端通过rpc和http通信
我现在的项目就是用gwt(rpc) + spring mvc + ibatis做的
我记得网上有个文章讲这个的 就是写一个service接受所有rpc 然后通过spring mvc转

好像还有一个开源的项目做了这个框架 不用自己写 google一下吧 |

on this thing. There is one question just pop up to my head: if a GWT form

data process and then forwards to a view which renders as JSON, than how
could that form or other GWT component catch this JSON? |

What I like most compared to GWT is that it has the option to do the so-
called Server+client Fusion. Developers are allowed to access the client-
side widgets directly if they want to. ZK Client Engine is based on jQuery.
Technically you can use jQuery-compliant libraries and widgets.
zkoss does have the problem of making too many ajax requests to server, so
the GUI may feel retarded if the network latency is too high.
Also I don't see third party zkoss widgets like Sma... 阅读全帖 |
