FileNotFoundException Jasperreports [英] FileNotFoundException Jasperreports

问题描述

1. 我在netbeans中加载一个jrxml文件，该文件已成功加载。
   
   但是当我将它部署为jar文件时，它会出现以下错误：

错误

    net.sf.jasperreports.engine.JRException: java.io.FileNotFoundException: src \Reports\print.jrxml(The system cannot find the path specified)

代码

try
{   
 jasperdesign=JRXmlLoader.load("src/Reports/print.jrxml");
} 
catch(Exception error) 
{
Notify.showMessageDialog(null, ""+error+"", "Error Loading Appointment JasperForm", Notify.ERROR_MESSAGE); 
}

推荐答案

我怀疑这位名为 src 在你的jar中

I doubt the dir named srcis in you jar

尝试使用 ClassLoader的方法getResourceAsStream 到打包的jrmx文件并传递它到 JRXmlLoader的加载方法，它将InputStream作为参数。

try getting an InputStream using ClassLoader's method getResourceAsStream to your packed jrmx file and pass it to the JRXmlLoader's load method that takes an InputStream as argument.

getResourceAsStream 的参数应该是完整的jar中jrxml的限定名称。也就是说，包括包名。

the argument for getResourceAsStream should be the full qualified name of the jrxml in your jar. That is, including the package name.
