试一下
FileResolver fileResolver = new FileResolver() {
@Override
public File resolveFile(String fileName) {
URI uri;
try {
uri = new URI(this.getClass().getResource(fileName).getPath());
return new File(uri.getPath());
} catch (URISyntaxException e) {
// TODO Auto-generated catch block
e.printStackTrace();
return null;
}
}
};

哥，我下来了你的etes，部署运行后，没发现有关报表的东东。能否给个全的sourcecode ，谢谢了！！！补充：Java , Web 开发
