Question

这是我第一次使用GWT。我正在按照教程：http://code.google.com/webtoolkit/tools/gwtdesigner/tutorials/stockwatcher.html

我无法超越GWT Java项目的创建。当我单击完成时，我得到：发生了错误。有关详细信息，请参阅错误日志 m_selectedModuleFile

当我查看错误日志时，我得到：

    and so on...

此外，您何时使用WinBuilder，何时应使用GWT Designer或Web应用程序项目？我不确定他们之间的差异。我正在寻找可以与App Engine一起使用的一些眼睛酸痛的东西。

Answer 1

这似乎可能在安装中出现了问题。我通常安装Eclipse Java EE版本（与Java不同），然后GPE减去Android部分（除非我需要设置它，然后在GPE之前安装Android SDK），然后安装WindowsBuilder - 用于额外的向导。之后一切正常。我创建了一个新的GWT项目（使用示例代码 - 更容易上手），然后可以使用任何向导。

Answer 2

事实证明我有一个旧版本的WindowBuilder，这导致了这个问题。但不确定这是否是整个问题。到目前为止它已经奏效了。
