seems to work better.

Anyways, good link, thanks!!
What I find the most troublesome is getting a good definition of Component Diagrams. There seems to be a zillion ways of doing them, both in the level of detail and in notation used.

I'm using Rational Software Architect from IBM, which doesn't use lollipop notation, but has a required interface and a provided interface section for each component.

First of all, the rule is not to talk about the assignment. Second - there is no correct/expected rule The key to the success is to prove your solution is correct, not to do as they expect you to do. Be creative! There isn't just one solution to part II, everyone can pass if he/she really knows what software design is.

I've removed the original post and the reply that appeared to be discussing a partial solution to the beta assignment.

Adam - thanks for reminding people of the rule. I removed the quoted section, but left the remainder since it is generic enough.

In a deployment diagram, I would thought a "3D box" represents a physical machine, say for example an application server, database server. In the link above, it shows the web server is different from the servlet engine. Is there any reason that we split the web server with the servlet engine?

I know it is possible where the web server is an apache server (for example) to serve static content, whereby the servlet engine is responsible to handle JSP and servlet requests, but it is *common* to split them into two boxes?

Hi,

In my opinion, this is very common. Think about clustered environment: you have one access point - a web server machine (without any static app content). On the top of webserver there is a JEE adapter, which redirects you to the appropriate application server handling your request. This way your web server box acts just like a proxy, and the application servers do the real job! Of course this is just a simplified image of how it works, but I hope that helps.
