Showing an external system in Sequence Diagram

Hi,

In Cade & Sheil example in the 3rd SD "Email Server" has been added and "sendMessage" is called on the "Email Server". Should it there be EmailDAO instead of external system?

Regards,
Krzysztof

Hello,

Guys, in yours sequence diagrams, did you depict an external system as an actor or a just regular box?

Hi,

Even I have same doubt "Cade & Sheil example in the 3rd SD "Email Server" has been added and "sendMessage" is called on the "Email Server". Should it there be EmailDAO instead of external system? "

Because we are referencing webservice into session bean by @WebServiceRef annotation, hence I dont think there is any scope of introducing DAO, but then any external datasource should be accessed using DAO. I am stuck in this point.

Can someone please clarify?
 
I agree. Here's the link: http://ej-technologies/jprofiler - if it wasn't for jprofiler, we would need to run our stuff on 16 servers instead of 3.
