warning in server

hello,

The problem has been rectified, now i am able to store the objects EData and
ToDo.

but in the server for each and every transaction i get an warning as
follows:


[warn] (691) InvokeServer: handleClientException():
java.net.SocketException: Co
nnection reset by peer: JVM_recv in socket input stream read
    java.net.SocketException: Connection reset by peer: JVM_recv in socket

org.ozoneDB.DxLib.net.DxMultiServerClient.run(DxMultiServerClient.
            java:41)
        at java.lang.Thread.run(Unknown Source)

how can i rectify this and why do i get this.  Server and Client are the
same machine.
thanx
bye
priyaa
