net.sf.jasperreports.engine.JRException：找不到资源 [英] net.sf.jasperreports.engine.JRException:Resource not found

问题描述

我尝试使用 JasperSoft Studio 使用子报表，但我在下面得到了例外。虽然它在那里但找不到子报告文件。

I try to use subreport using JasperSoft Studio but I get the exception below. It cannot find the subreport file although it is there.

net.sf.jasperreports.engine.JRException:Resource not found at: D:\\JASPERREPORTS\\MyReports

以下是主报告的配置

推荐答案

按照Sharad的回答，如果它仍然没有生成该文件（发生在我身上），你可以试试这个：

Following Sharad's answer, if it still doesn't generate the file (which happened to me), you can try this:

在预览报告之前，你可以先尝试编译它。如果打开jrxml文件（包含子报表的文件），您可能会在编辑器的上方栏中看到一个小图标（带有一些二进制字符串的小文件）。单击此按钮应生成您期望的文件。

Before previewing the report, you can try to compile it first. If you open your jrxml file (the one that includes the subreport), you may notice a little icon (a little file with some binary string) on the upper bar of your editor. Clicking this button should generate the file you're expecting.

我创建了一个新答案，因为我想添加一个显示按钮的图像：

I created a new answer because I wanted to add an image showing the button:

请注意，这也可能有效：使用Project> Clean ...清理包含报告的项目。然后在Project Explorer中右键单击您的项目（通常在左侧），然后单击Build Project。

Notice that this may also work: clean the projects that contain the reports using "Project > Clean...". And then right click your project in the "Project Explorer" (usually on your left), and then click "Build Project".
