business delegate is proxy to the service layer. its perfectly legal to call an
external system over SOAP/JCA from your session facade. you should not be
writing that logic directly in the facade but should delagate it to some
handler class.
Business Delegate -> Session Fa?ade -> Business Object -> SOAP Handler
hope it helps

Subject: Business Delegate and Web Services
Hi list.
Briefly, our architecture follows:
Business Delegate -> Session Fa?ade -> Business Object -> DAO -> DB
Our Use Cases are implemented in the BusinessObject layer.
The problem:
We have to call a webservice from our Business Object layer. This
webservice is hosted outside our company.
I suggested to create a BusinessDelegate to encapsulate this call, so our
business rules wouldn't be mixed with those xml/soap technical details. In
this situation, our system would be designed as:
Business Delegate -> Session Fa?ade -> Business Object -> Business Delegate
-> Web Service
Others think that BusinessDelegate is not an integration pattern, and the
DAO should be used instead:
Business Delegate -> Session Fa?ade -> Business Object -> DAO -> Web
Service
What does the list think?
Cheers
