The MQ WF Java API provides a finish() method to complete a work item. I would like to know if finish() can be part of an application's unit of work. Further can any MQ WF Java API be part of a unit of work?
Example:
If I want to finish a work item and update the application's data base in a single unit-of-work, can I do this using the Java APIs? This would be useful to keep the MQ WF Business Process and the application data in sync. |

Steven:
Based on my understanding of MQWF, it only cares about its own database. I.E. application database calls are not transacted. Here I am talking about an ActivityImplementation. If, on the other hand, you are writing a UPES, you can control the transaction yourself.
This question would probably best be answered by one of the MQWF Developers, you might want to post it to the IBM mqwf newsgroup.

MQ WF java API does't participate in transactions....once done is done...there is no way to revert back using java API....
What best u can do is....always keep WF Java API call last in the transaction. So if this call fails entire thing can be rolled back.
As Jmac said u can cotrol transactions if u are using UPES. |
