The following warning message may be observed in the fixaj.log file while placing the order.xml file each time:

[WARN ] [MRThread:targetId-senderId] [b] Method onNewMessage of user listener thrown exception: Invalid message type: 8
[WARN ] [MRThread:targetId-senderId] [a] Invalid message received: 8=FIX.4.49=19135=849=senderId56=targetId52=20120403-14:23:32.53334=11437=ORD:3000311=9000100817=EXECID-

java.lang.IllegalArgumentException: Invalid message type: 8

Workaround:

Ensure that one of the following parameters are set in the properties file:

• Always. The session will send logon with 34= 1 and 141=Y every time (during connection and reconnection).
• OneTime. The session will send logon with 34= 1 and 141=Y only one time (during connection).
• Never. This means that user can set the 34= 1 and 141=Y from session parameters by hand.

This is not something that is implemented by iWay. It is just passed as a configuration parameter to the B2Bits FIX engine. However, different behavior is sometimes observed depending on how it is set. Ensure you do not also have it set in the configuration file because the values in the configuration file take precedence over the values you specify on the provider page. In addition, be advised that if you update the provider parameters you must restart iSM for them to take effect.
