大师们救救我！报表编译报错。

Java code

我设计好了报表放在sampleReportFile + ".jrxml"，然后加载进来，再编译。如下代码JasperDesign design = JRXmlLoader.load(sampleReportFile + ".jrxml");            //编译JasperReport report = new JasperCompileManager().compileReport(design);//这句有异常这两行代码放的一个单独的类中的main里能正常运行。但是放到我的项目中就报异常，无法编译，抛出异常如下(myReport_1216356285140_165076.class这个文件是它自动创建的怎么找不到？但在单独类中的main中为什么行？)。java.io.FileNotFoundException:

[解决办法]
D:\other-workspace\TestReport\myReport_1216356285140_165076.class有这个文件吗？
看看你的文件系统中是否有这个问题件，如果没有，检查是不是你的环境配置的问题，比如配置到另外的目录了
[解决办法]
我试了下,怎么没看到class文件,只出现了java,jasper,还有一个就是配置中的文件,我配置的是pdf,然后就多了个配置文件
估计LZ是配置的问题,LZ用的是IReport吧?不是有文档么,照着再配一次

它报的是找不到指定文件么...系统要这个文件.但是在这个目录下找不到..
所以.我想是你的配置哪个环节有问题..所以生成的这个myReport_1216356285140_165076.class 没有在那个目录下.
你在main里面可以是因为生成的这个myReport_1216356285140_165076.class 在同一目录下，所以不存在找不到class咯
