看这些内容能大概知道是什么错误吗？
这行的代码是这个client.service.ClientService.addClient(ClientService.java:18)

List fileInfoList = client.getFiles();
FileInfo fileInfo = (FileInfo)fileInfoList.get(0);
这行是client.action.ClientAction.addClient(ClientAction.java:25)
clientService.addClient(client);

是类型转换错误。估计是下面的出了问题。
List fileInfoList = client.getFiles();
FileInfo fileInfo = (FileInfo)fileInfoList.get(0);

帮顶

ClassCastException

强制类型 转换错误

FileInfo fileInfo = (FileInfo)fileInfoList.get(0);

看看fileInfoList集合存放的类型是FileInfo 类型不

检查一下

FileInfo的包路径不同,然后类也就不同,就出现类转换异常!
仔细的检查下!
