I modified the included Java sample SendFile.java (see below) to use transactional support.

I tried both with AMT.SAMPLE.POLICY snycPoint on and off.

I get the following error:

D:MQSeriesamtsamplesjava>java SF -t SF.java
>>> START AMI Sample SF
create()
open()
SF()
>>> AMI SF experienced an Exception ...
java.lang.Exception: <<< AmError >>>
from method[begin]
of class[AmSession]
with reasonCode[54]

>>> END AMI Sample SF

I modified the SendJava code by renaming the class from SendJava. I then inserted the following line:
mySession.begin();
before the sendFile method and:
mySession.commit();
afterward.

Anyone have success with snycpointing/Java/AMI?

My first question would be whether or not you are using 2-phase commits under XA? Because if you aren't, you don't need to issue the begin command. As soon as you do an MQGET or MQPUT while specifying syncpointing, a new unit of work should begin. It will continue to grow with subsequent GETs and PUTs, and will be completed once a commit or backout is issued. You only need to issue a begin if you are doing resource coordination with an external system (like a database)...

Thank you. I took out the begin and it works.
