Hello Ranchers,

I have been a silent member of this group and now need your help in order to complete the 2nd and 3rd parts. I have a few questions.

1) How do I show an external system in the Sequence Diagram?

Almost all questions and responses on CodeRanch are welcome, however there are very specific rules for our SCJD and SCEA forums. These are spelt out in the SCJD specific rules, and the SCEA FAQ. More generic rules about certification issues are spelt out in our policy on real questions.

In looking at your post, I felt that part of it was discussing a real solution, so I had to delete it.

Perhaps you could re-word it to be less assignment specific?

Is it a good design to have a separate stateless session bean for handling payment or could it be part of other session bean?
I agree. Here's the link:
