Hi Maybe I have found the root cause. It 's the start byte. My program is used for Japanese Customer. In Japan, the HL7 message is no start byte. And the sending tool I used cut the start byte of sending message automatically.
Then I find the related log : " 2011/02/10 20:03:36.968: <WARN> [HL7MLLPDecoder] writeString(66) {AnonymousIoService-2} - No start byte found, reading from beginning of data " After I added the start byte, it works. Thanks for both of your kindly help again.
