java - JBoss 类路径问题

Question

在 /class 下的 java 代码中，我有

str_url = "/jasperReports/report.jasper";
url = getClass().getResource(str_url);

实际的report.jasper模板在

Application.war\WEB-INF\classes\jasperReports

从war文件中，但现在应用程序给了我以下异常：

net.sf.jasperreports.engine.JRException: java.io.FileNotFoundException: 
C:\Windows\System32\content\Application.war\WEB-INF\classes\jasperReports\report.jasper

那么发生了什么以及为什么应用程序在 下查找模板System folder，那根本不是临时文件夹或缓存文件夹。

更新

部署应用程序时确实出现异常：
