RE: UML Diagrams for Struts
I agree that this would be a good resource to have. In particular, it would be good if struts could be defined (perhaps using UML) as a design pattern. This would enhance understanding and enable synergy with similar projects like Turbine. -Original Message- From: Hines, Bill [mailto:[EMAIL PROTECTED]] Sent: 31 October 2000 18:29 To: '[EMAIL PROTECTED]' Subject: UML Diagrams for Struts Does anyone know of or have any UML type diagrams for the struts-type model 2 core behavior?

David Geary's article about Struts in this month's Java Report includes some class and sequence diagrams that I found helpful.

Lori, I think I found the article he was talking about at: http://www.javareport.com/html/from_pages/column.cfm?articleID=1615 It doesn't mention struts (just at a glance) and I don't think it is by Geary, but it does have some UML diagrams!

I really appreciate it. One question I had for you, though, is where the StartUpServlet comes from. I am assuming that it is a custom servlet you had created to initialize the webapp? I have the same problem: how to initialize the app (building connection pool, find EJBs, etc). Has anyone else given this any thought? One solution would be to specify a startup class in the actions.xml file. This class implements init() which is basically called by the ActionServlet's init(). Any ideas? Thanks, Seth
RE: UML Diagrams for Struts
You're right. I will have to implement a StartupServlet. For now, it is only on the design document. Same remark for the ConnectionPool class. I'll use one of those which are available as Open Source on the Net.

Thanks for the UML diagram for Struts. Is there any further description about the relations / differences between BusinessObject and BusinessObjectBean. How do you seperate them, what's in the Object, what in the ObjectBean ? Maybe an example would be very helpful ...

RE: UML Diagrams for Struts
The role of the BusinessObjectBeans, which conform to the javabean specifications, is to contain the data needed by the JSP pages. So, when a JSP page is about to construct an html page, it will ask the BOBean to provide the required data. So, the BOBean are the way the Presentation layer is communicating with the Business layer, or the model. The Presentation layer only access the model through the BOBeans. The BusinessObjects are private classes of the model, which are not intended to be used by the JSP developer. While BusinessObjectBeans are pretty dumb, the BusinessObjects host the business logic, or business rules. They know how to calculate the information which will be stored into BOBeans for the JSP's. Any comment on this philosophy is welcomed.

Any ideas? > Application initialization is a little bit clumsy under servlet versions < 2.3. The solution I chose in the Struts example application was to create a separate servlet (DatabaseServlet) that fulfills the role of the startup servlet in the diagram, and then made sure that it is marked in the web.xml file. That way, it will get loaded before requests are processed, and can initialize global resources, storing them as servlet context attributes to make them visible to the rest of the app. The clumsy part of this, though, is that I put the code to gracefully close these connections in the destroy() method of DatabaseServlet, based on the assumption that the servlet container will not actually remove this servlet while the app is running. That is true for many / most servlet containers today, but is not guaranteed. Under the new Servlet 2.3 spec, however, there is a new feature -- application events -- that is designed to deal with this situation gracefully. You can register (in web.xml) a listener class that is notified when the application is started, and when it is shut down. This is a perfect place to do initialization and finalization type activities. > > Thanks, > Seth Craig McClanahan
