Question

我为远程数据库创建了一个简单的SOAP Web服务，它在WebLogic 12c服务器和Jdeveloper HTTP分析器中运行良好。当我在下面的代码中使用相同的Web服务时，我收到以下错误（我已将参考流中的System.out.println输出包含在代码流中）我使用的是Jdeveloper 12C MAF 2.0.0.0。在Mac OSx 10.9上有41个。

Answer 1

这可能不是这个问题的答案，但它可能是搜索＆＃34; 无法读取DataControl用途的答案，在loadDataControl上为id ＆＃34;

就我而言，它适用于Oracle MAF，但这也适用于Oracle ADF。

您的Web服务需要位于DataBindings.cpx文件中。

像：

＆＃13;

<dataControlUsages>
    <dc id="WLFNewActWS " path="mobile.WLFNewActWS "/>
</dataControlUsages>

＆＃13;

我欺骗并将一些东西从WS拖到一个页面中，并让jdeveloper为我添加DataBindings.cpx中的记录。

Answer 2

发生绑定问题。请在amx页面中创建对“WLFNewActWS”的引用/绑定。它会解决你的问题......！

Oracle MAF错误“无法读取DataControl用法，在loadDataControl上为id：”
