Quickfixj / OMS problem (Redifining datatypes, sending separate loin messages)

[Morris Mwanga]

Hi all,
We are using the marketcetera 0.4.2 platform to connect to an exchange,
The exchange requires a logon first, then an applogin. I could not manage
to login using the oms.
I managed to get the log-file of a previous successful login and it looks
way different. Here it is

-------------------------
Here is a successful logon message...

INPUT:
9000=20080728-08:59:46
:8=FIX.4.4
9=91
35=4
34=1
43=Y
49=DWD
52=20080728-09:00:17.409
56=RBS
122=20080728-09:00:17.409
36=3
123=Y
10=185



Followed by an applogon

INPUT:
9000=20080728-08:59:47
:8=FIX.4.4
9=121
35=UA
34=3
49=DWD
52=20080728-09:00:18.331
56=RBS
553=skariuki
554=nse123
6348=1.1.1.1
6364=10.64.10.32
6400=1234
6731=0
10=198


-------------------------

This is my message from the same exchange

INPUT:9000=20080728-08:59:45
:8=FIX.4.4
9=61
35=A
34=2
49=DWD
52=20080728-09:00:15.972
56=RBS
98=0
108=20
10=207


-------------------------

Now, I need to be able to do 2 things

1)I need to be able to send two messages for login, one after the other
(not all together)
2)I need to be able to redefine my data dictionary (So that tag 35 can be
type 4 and not type A, and so on and so on)

Any help would be appreciated

Morris,

In the sample messages that you sent, you have
1. a SequenceReset message, not a regular "logon" message
2. a custom message (MsgType=UA) where you specify your username and password

The message that you get back is a regular Logon (MsgType=A) message.

> Now, I need to be able to do 2 things

You'd have to do that manually - you make some changes in the
org.marketcetera.ors.QuickFIXApplication.onLogon() method to send
another message out when you receive a reply to a logon event.
Alternatively, you can overwrite the toAdmin() message to send an
"applogon" or a custom message following your first outgoing Logon
message.

does that work for you? We don't have an API yet to insert custom
adapters/additional messages for outgoing Logons, but it seems like
it'd be a good idea to allow for that. I've filed an RFE:
http://trac.marketcetera.org/trac.fcgi/ticket/529

That's very simple. Follow the directions from here:
http://trac.marketcetera.org/trac.fcgi/wiki/0.5.0/Marketcetera/UserFAQ#MybrokerdeviatesfromFIXspec.HowdoIuseacustomFIXdictionary

You can use any of the FIX dictionary from QFJ as the starting point:
http://quickfixj.svn.sourceforge.net/viewvc/quickfixj/trunk/core/src/main/resources/

let me know if you have any other questions. I'd be happy to discuss
the customization of the QuickFIXApplication with you privately if
need more directions.
