java - 碧 Jade 报告 : Resource not found

Question

我正在使用 Netbeans 7.1 进行开发。

在我的碧 Jade 报告中，我有子报告。它在一个地方完美地工作。我复制并粘贴到另一个地方，现在显示此错误:

Answer 1

路径 D:\ShareMarket\build\web\WEB-INF\classes\custom\kksharemarket 可疑。它应该是 /custom/kksharemarket 因为它位于您的应用程序的类路径中。应用程序可能打包在 jar/war 中，文件路径不行。可能资源也不是通过文件系统获取的，而是在类路径上获取的。这通常是“资源”在 Java 术语中的含义。

它适用于第一次开发，因为存在目录结构。
