Customized deserialization

[sreek, Thiru]

Is there any mechanism in java, which enables us to browse into a serialized file and deserialize a specific object???
I some how stored the offsets of diff objects in the serialized file. but when i try to skip through the ObjectInputStream while deserializing it gives me stream corrupted Exception I tried to use skipBytes(), read(),readBytes()... all of them give me
StreamCorrupted Exception: reached EOF in stream... Any info in this aspect would be of great help.
Thanks
