Would like to check if there is an way to validate resolve the services for jpos if the message header indicate the length as 100 however the sent length is 99? Currently when i received the message from my client end it would required to restart if not the sequence message would fail.
Thank you in advance.
Such a message is malformed an should be rejected. It expect most operators would flag this because its an indication of a major software fault somewhere along the line.

I'm learning about POP3 by reading RFC 1939.
The description of the RETR command says the following:
Possible Responses:
+OK message follows
-ERR no such message
Examples:
C: RETR 1
S: +OK 120 octets
S: <the POP3 server sends the entire message here>
S: .
What does "120 octets" refer to? Is this optional information about the message that may or may not be included, and if so, is "message follows" not required (as specified under "Possible Responses")?
What does "120 octets" refer to? Is this optional information about the message that may or may not be included
Correct, the "120 octets" is optional informational text but is not required text nor can the number of octets be used as definitive for calculating the end of the message data.
and if so, is "message follows" not required (as specified under "Possible Responses")?
That's why it was stated to be a "possible response" ;-)
Basically, all you can really use from that first line is the first token which will be "+OK" or "-ERR". Everything after that is informational text that may be a helpful when debugging, but not guaranteed to be useful for your code to try and interpret.
I would argue that if it is of the form "# octets", you might be able to use it to show progress as you read data, but that's about the best you can do.
Even so, I would probably recommend using the octet value from the LIST command instead.
Our FIX Engine implemented in QuickfixJ send the received quote message in the quote session to another application listening on JMS queue for further processing like persistig to DB.
The message serialized and de-serialized using Apache serializationUtils.
The problem is, the application throws FieldNotFound error when it attempts to retrieve SenderCompId header field from the de-serialized message.
setSenderlocid(header.getField(new SenderLocationID()).toString())
quickfix.FieldNotFound: Field [142] was not found in message.
at quickfix.FieldMap.getField(FieldMap.java:216)
at quickfix.FieldMap.getFieldInternal(FieldMap.java:353)
at quickfix.FieldMap.getField(FieldMap.java:349)
Does serialization work with QuickFixJ messages?
I'm trying to handle UDH data for multipart messages and I want to use an appropriate error code when there's a problem with the multipart fields. There are several error codes for bad TLV's, but I don't see anything except generic failure messages that I could use for UDH. Is that the best I can do here, or is there a more direct message I could use?
Your observation is correct - there is not a single error defined for UDH.
If you want, you can use error codes from reserved section and assign specific meaning to one/some of them. I think the "Reserved for SMSC vendor specific errors" (0x400-0x4FF) can be a good candidate.
Actually it looks to me like ESME_RX_R_APPN = 0x66 "ESME receiver reject message error." is the best error code to throw here.
It should correspond to a permanent error for this message only and let further messages be processed.
when sending a specific CAN message via chanel 0x74D the lenght is specified in l=8 and the response must contain several Ca, msg, unfortunatly i receive only the first one, please note also that all the received msg are in chanel 0x76D .
im using C# code, here attach a question that i have answered but with no response

any idea on how to do that ?
"The action of the default handlers is to print an explanatory message and exit." (link)
Example of such message:
X Error of failed request: BadWindow (invalid Window parameter)
Major opcode of failed request: 12 (X_ConfigureWindow)
Resource id in failed request: 0xc0007a
Serial number of failed request: 140
Current serial number in output stream: 141
If I set (XSetErrorHandler) my own "ignore everything" error handler, the "explanatory messages" disappear.
How to make Xlib ignore errors, but still print error messages?
If you actually want those error messages you pretty much have two options:
Pull _XPrintDefaultError out of XlibInt.c along with some private headers (with all the caveats of using library-private definitions).
Redefine exit() not to actually exit when _XDefautError calls it.
Neither is especially pretty and both may break and reduce your portability, but they do work.
You have to format your own message. The contents of the message is the contents of the XErrorEvent struct:
