序列化：读取序列化文件失败

Question

我的代码是：

try {             
                        // De-serialize it!
                        ByteArrayInputStream fis = new 
                        ByteArrayInputStream(serFile);
                        GZIPInputStream gzis = new GZIPInputStream(fis);
                        ObjectInputStream ois = new ObjectInputStream(gzis);                
                        reptDef = (AdHocReportDefinition)ois.readObject();                  


                    }

我在读取seralized文件时在ObjectInputStream上收到此错误。
