racters

String keyValuePair =3D null;
String[] arrKeyValue =3D null;
BufferedReader in =3D request.getReader();
while ((keyValuePair =3D in.readLine()) !=3D null) {
arrKeyValue =3D keyValuePair.split("=3D");

Above code reads incomplete data(read only 8192 bytes) at my customer's env=
ironment, but reads complete data in my environment.

String keyValuePair =3D null;
String[] arrKeyValue =3D null;
BufferedReader in =3D new BufferedReader(new InputStreamReader(request.getI=
nputStream()));
while ((keyValuePair =3D in.readLine()) !=3D null) {
arrKeyValue =3D keyValuePair.split("=3D");

Above code reads complete data in both the environments. *no changes done t=
o customer's environment.

I hope you can help me now by finding the reason for data lost at my custom=
er's environment when using request.getReader().

Thanks and Regards,
Harish

.. and the difference between two systems, may be that on one system, the n=
etwork is=20
faster (or the system slower, or the buffer bigger) and so by the time you =
do the read,=20
there are more bytes available in the buffer.
