how to send and receive objects using sockets, serilization exception in socket programming

hello all

I am writing a file transfer code

I serialize an instance of filetransfer class
add chunks of file data to the object and then serialize that object.
after serializing I add a one byte of marker which indicates the end of the object data.

upon receiving each packet is added to a list of byte[] byte array.

once the receiving is done I create another list in which the data is rearranged with respect to the end marker.

I deserialize each byte array in the rearranged array to reconstruct objects and get file data. the code works for small files but fails for larger files with the serialization exception.

Please help how to send and receive objects using sockets.

Thanks all
