String path = scontext.getRealPath("src/main/webapp/relatorios");
JasperPrint jasperPrint = JasperFillManager.fillReport(scontext.getRealPath("src/main/webapp/relatorios")+ File.separator+relatorioNome+".jasper", parametros, dataSource);
```
也就是说，他引用了src/main/webapp/relatorios中的文件。这可能适用于有源文件树的开发机器上的测试类，但Maven通常不会将src文件夹放入最终部署的WAR中

然而，在本案中，所讨论的文件来自^{。此文件夹的内容将复制到WAR根目录中。因此
```
String path = scontext.getRealPath("relatorios");
JasperPrint jasperPrint = JasperFillManager.fillReport(scontext.getRealPath("relatorios")+ File.separator+relatorioNome+".jasper", parametros, dataSource);
```
应该有用。尽管如此
- 我不确定JBoss是否真的提取了战争。如果没有，就没有真正的道路。但是，查看文档，可以看到getRealPath返回null，如果servlet容器无法将给定的虚拟路径转换为真实路径由于问题与null值无关，因此JBoss似乎在提取
- 我怀疑你是否想公开你的*.jasper文件。但在你的情况下，他们似乎是
