Single source sending data through multiple messages to a single reciever

Question

Hi all,
I am trying to implement the below scenario:
- I am reading from table1 in a database using a sender channel1. Based on data retrieved, I perform a JDBC lookup on table2 (in same d/b) using a reciever channel2 in an UDF of a message mapping1.
- The data retreived from table2 is mapped to an intermediate format1. A mapping between the intermediate format and target message type1 is performed and message is sent to the recieving system using a reciever channel3.
- Now, I need to map data retrieved from table2 to different target message types1,2,3.. based on some criteria and send it to the same reciever. I intend to use a different target message type and intermediate format for every kind of data obtained from table2 and a corresponding mapping.
I plan to do this without using a BPM. Is it possible? If yes, then are the 3 communication channels sufficient to achieve this or do I need to have more communicatin channels?
Any help would be appreciated.
Thanks,
Amit

Answer 1

This is pretty straight forward...
change your design as folllowing :
1. as you have both table 1 and 2 in the same database , you can directly write a join query to pick data from both the tables . this can be specified in the sender jdbc adapter
so your source data type would be like
row..0..un
+f1(field from table 1)
+f2( field from table 2)
+f3(field from table 2)
2. now just create 3 seperate mappings
mapping 1 = between source structure given above and target MT1
mapping 2= b/w source struc given above and target MT2
mapping 3 = b/w source struc given above and target MT3
3. use 1 receiver determincation ...1 interface detemination where you keep on adding the message interfaces and interface mapings created above..
4. use 3 receiver agreemetns
