How to update XML source in ALDSP 3.0?

Question

1. ALDSP 2.5 provides a updateovrride class at server side for programmer to write custom update logic for Non-XA data source.
how does ALDSP 3.0 do update with XML data source???
2. I wrote a simple trigger service for ALDSP 2.5. It processes the datagraph, that is sent to the performUpdate() method of UpdateOverride class at server side, and analyses the update type and update location in the data object. According to this information, the trigger service loads some predefined triggers and performs the action part of these loaded triggers. All this happens at server side and in the performUpdate() methode.
Now it seems that there is no UpdateOverride class in ALDSP 3.0, how can i call my trigger service at server side? :-(

Answer 1

In ALDSP 2.5 (and ALDSP 3.0), non-XA data sources can be updated without writing an update-override. But if you want to do any special processing that is not handled by the default behaviour, or for data services not based on relational databases, in ALDSP 2.5, you can write an update-override.
In ALDSP 3.0, the update model is somewhat different, I suggest that you peruse the ALDSP 3.0 documentation for a thorough discussion. The documentation is here http://edocs.bea.com/aldsp/docs30/index.html I suggest start with a search on 'update'.
In ALDSP 3.0, I believe updateoverride feature still exists for the purpose of backwards compatibility (at least it turned up in a search of updateoverride in the 3.0 docs)
