The easiest way to avoid this problem is to keep the OutputStream open when you write the data, instead of closing it after each object. Calling reset() might be advisable to avoid a memory leak.

The alternative would be to read the file as a series of consecutive ObjectInputStreams as well. But this requires you to keep count how many bytes you read (this can be implementd with a FilterInputStream), then close the InputStream, open it again, skip that many bytes and only then wrap it in an ObjectInputStream().
