我花了很多时间分享两个GWT模块的数据源。
我已经尝试了一切。我会张贴一些东西,但不确定它会有什么帮助,因为我已经对它做了这么多修改。 关于如何在两个GWT模块之间共享数据源的指导/研究?
我有一个问题。 一个模块会将数据添加到源头, 源代码会进入 HSQLDB 中以保持持久性。 这很好。 但是第二个模块不会接收添加的数据。 如果我试图显示第一个模块的数据, 我就不会遇到问题 。
我在两个模块中使用“ 数据源. get (“ DS_ Name ”) ” 。
在每个 HTML 中,我都添加了这一行:“[Scrcs="FirstModuleName/sc/Data source Loader?数据源=DS_Name" [/prity]”。
有什么想法吗?
由于这是SmartGWT, 您第二个模块的 html 中, 请确保无形态的 Dir =" FirstModuleName/ sc" 。 这应该为它提供数据源 Loader 的正确路径 。
