Using Multiple Threads

The annotations described above for asynchronous consumption are also used in the multi-threaded execution model. In this model, the POJO SE executes the POJO instance methods annotated with Operation, OnReply, OnFault, and OnError concurrently when the response messages are received. Since many transaction managers only allow one thread to be associated with a transaction, by default the transaction is not resumed while executing any of the POJO instance methods such as those annotated with Operation, OnReply, OnFault, OnError, and OnDone. Transaction objects are also not propagated to asynchronously consumed services.
