Delphi XE – Datasnap Filter problems -


i have tcp/ip datasnap -xe server uses pc1 , zlib filter

on client both of these filters defined in datasnap tsqlconnection

when client connects server "connection closed gracefully” error message

if use pc1 filter on own - there no problem

if use zlib filter on own - there no problem

any ideas on how can both filters working @ same time?

you need deploy libeay32.dll , ssleay32.dll client application well.

a quote delphi xe datasnap development courseware manual:

"if deploy datasnap standalone server, using tcp/ip , rsa , pc1 filters, must deploy 2 indy specific ssl dlls: libeay32.dll , ssleay32.dll – or make sure exist @ server machine. these dlls needed rsa filter (which encrypts password used pc1 filter). without these 2 dlls, client wants connect server “connection closed gracefully” message, because server unable load 2 dlls start rsa filter encrypt pc1 keys, etc.

by way, same 2 dlls required datasnap client, whether connected tcp/ip server using rsa , pc1 filters, or whether connected isapi filter using https."
