Hi, Looks like the sending application (or receiving application when sending the acknowledgement) is violating the hl7 minimal lower layer protocol.
The basics of MLLP are that the start of a hl7 message that is sent over the tcp/ip network should be indicated by a ASCII 11 (or hex 0B) and terminated by ASCII 28 (1C) and 13 (0D). See http://www.hl7.org/v3ballot/html/infrastructure/transport/transport-mllp.htm#MLLP-block for more info about MLLP. If your sending and receiving applications run on different pc's you can use Wireshark (http://www.wireshark.org) to monitor the network traffic and verify (follow tcp-stream) if both applications are sending the right MLLP characters. Hope this helps Best Regards Nico At 17/12/2008, Dayu Han wrote: >Hi All > >I've come to this exception when sending an ADT message.
