[Quickfixj-users] BUG? - Re: InvalidMessage exception
|
From: Alvin W. <AW...@FF...> - 2007-03-08 21:05:37

OK, I took the pain to step into QFJ's codes. In Message.java, we have:
public Message(String string) throws InvalidMessage {
fromString(string, null, true);
}
DataDictionary is null, as a result, it cannot parse a message with group
correctly. My question is what is the use of the constructor if it cannot
handle group at the end?
I do not have this problem with QF java wrapper. It has the following:
public Message(String string) throws InvalidMessage {
initFromString(string, true);
}
private void initFromString(String string, boolean validate)
throws InvalidMessage {
create();
header = new Header( this );
trailer = new Trailer( this );
fromString(string, validate);
}
That means QF java wrapper can validate without the dictionary.... (Oren,
maybe you can clarify a bit, i did not go down to C code after this...)
thanks...

Can you show us an example of the message string that you're passing in
from the counterparty, along with the reported actual and expected
message lengths? It might give a clue as to where in the message the
problem is occurring, and in turn help nail where in the code the
problem is.

for 1.0.4 but broken in 1.0.5?

Basically, I received the message from counterparty via FIX as a string,
then I use "new Message(String str)". It is correct that that message
string contains some repeating group, but that should not be relevant as
the message is not built by my code, instead it was received as a
string.
I am using QuickFIX/J 1.0.5, I just wonder if there is any change in
FieldMap.java from 1.0.4 to 1.0.5?
Thanks.

In general terms it's simply saying that your FIX message isn't
constructed properly.
I think this can happen when you don't build a group properly, for
example adding fields to the body directly rather than as part of a
group. Another possibility is that you have a RawData field without a
RawDataLength preceding it.
It would help to see the code that's building the message header and
body, including construction of any groups, if the above doesn't help
you fix the problem.
Regards,
Toby
