Hi !
I have the following problem that i want to solve with MDB, but i don´t know who to do it.

Image that i have 1 million clients orders that i want to process at some time.
I want to generate on a mdb, messages to process later something.

But i want to process several messages at same time, but for a client it has to sequencial.
Example

send message client 1 process data 1
send message client 1 process data 2
send message client 2 process data 1
send message client 3 process data 1

I want that the flow is the following:

jboss
process client 1, data 1              
process client 2, data 1             
process client 3, data 1             
  end process client 1, data 1              
process client 1, data 2             
end process client 2, data 1              
end process client 3, data 1              
end process client 1, data 2              

How can i do it?

best
