Re: [OT]: Struts, Web Development, J2EE, and what is too much?
Aaron, Try not to think just in terms of EJBs. Instead picture the scenario of persistence management in general. Throw CMPs, BMPs, JDO, Session Beans, Etc. out on the table and consider what each is buying you. In some cases the benefit is in providing a JNDI lookup for other Apps to use if you have several clients using your module. In other cases the benefit is in the memory management features that allow an EJB container to out-perform the servlet container. For myself, I am in the process of ramping up the use of JDO within stateless session beans and Struts is providing the major command pattern breakout of different use cases in the servlet container. A lot of the lower level conditionals and case statement logic for data gathering/updating is in the session beans... some of which uses the strategy pattern for conditionally different persistence management operations. -Tony Aaron O'Hara [EMAIL PROTECTED] wrote:I know this question has probably been asked before, and that biased publications have had their opinions on it, but I wanted to get some feedback regarding some real user experience regarding the use of EJB in a web application used along with Struts.

The application needs to be high performance, uses a single database (so it doesn't have heterogeneous transactional db requirements). I have designed the application in layers, and it will only have a web interface. It's starting small, but will grow to have many functions. Even though I'm confident that I need not invest in EJB's, I don't want to develop the application to find out I should have used them (hence why I'm creating this post). In what scenarios have people found the use of EJB beneficial? When have they been overkill? Does struts integrate smoothly with EJBs?

Is this the case with tomcat? I did not think so. It is. The element (in web.xml) includes a section that maps URL patterns to the role(s) that a user must have in order to access that URL. This is all in the servlet spec, and portable across containers. The only part that's not portable across containers is how you actually set up the users and roles database (in Tomcat terms, that is a matter of which Realm implementation you use). Our needs our very similar. The users with a admin page that allows them to change access to pages. For Tomcat specifically, this can be done easily if you use a JDBCRealm to get user and role information from a database. Then, writing an admin program to manage users is just like any other database maintenance application -- just make it update the same tables that JDBCRealm is using to authenticate and authorize users. Struts also has some built-in support for checking roles dynamically during execution: * You can use a roles attribute on an to limit which users can execute that Action. * You can use to conditionally display parts of your UI to only people that have the role you specify.

Re: jsp, multiple forms and beans
Jacky,
Recently an associated of mine became tired of trying to get DHTML to work properly
between NS and IE and came up with a crafty way of hitting the server just to pass a
flag value in a request parameter to tell the JSP to add a new section of HTML to the
page without affecting any other data that had already been entered on the page. The
Action class basically did nothing but route the request to the same JSP page.
He used a single form per page and named the line item input field(s) with [counter]
and the Form class set accessor method was something like setX(String key, String
value) { x.put(key,value); } where x is a HashMap. Both the JSP and Action class that
processes the data use a loop to pull data out of the HashMap where key = 1, 2,
3 etc. until a null value is returned.
Although this is a bit creative and worked, I am not sure if it is recommend by the
Struts old-timers.
I would avoid using multiple Forms per page. I would also avoid any use of the
innerHTML for dynamic client side adding of input fields into a Form. About the only
choice left that I see is to make a server hit and let the JSP build more line items.
Anyone else out there use something like a NoAction action for this sort of thing?
I hope this helps?

Re: Role Based Struts Validation

Re: perform method deprecated??
If you really like having the perform method separate from the execute, just keep it. But extend the Action class to create a new base class. That way, if perform is ever permanantly removed, your code will still work. For instance, I created a base class that extended Action and called it CounselorAction ( for all the actions applicable to the business rules for counselors - whoever they are) and then packed a lot of common code before/after the call to the perform method inside the execute method. This way, all the action classes for counselors inherit all the common functionality. I ignore the deprecated warning in this case since I know what it is. An alternative that I have seen is to create a second command pattern with is own base class and child classes for the business logic and execute those from the execute method in the child Action class but then the number classes that you have to write is doubled for each action. -Tony julian green [EMAIL PROTECTED] wrote: Andrew Hill wrote: Your upgrading from 1.02 Yes, and until the next non beta release is made that is where I will be staying.

DynaBeans, Struts, OR mapping tools and code generators
Has anyone seen any effort afoot to make a drag-N-drop between a GUI like the one in MiddleGen and an ActionForm so that you can build your pages using point and click and have all the code generation for the action classes, DTOs/VOs, EJBs/DAOs done behind the scenes xdoclet style. I know the propriatary nature of some databases and app servers makes this a little difficult but it looks like a lot of pieces for this are starting to fall in place. Especially with the new commons-beanutils with features such as RowSetDynaClass (as recently mentioned by Craig) I don't mind coding all this stuff by hand... Not!... and don't mind trying out various popular OR mapping tools and code generators (free ones that is). But it seems like someone might be looking at assembling into a single tool many of the loosely coupled projects not only at Apache but also sourceforge. I am looking forward to see what the SUN Faces product will do and how Struts and JSTL relates to or is incorporated into that but I do not know easy it will be to map database fields to a face. But for my next scheduled development with Stuts 1.1 and the new commons code, this looks like still a lot of hand coding or hand configuring of code generators... I suppose I'll need to ask each of the current tool's user lists to see if they are planning to support some of the new features and integration with Struts. :) But I wanted poll the great Struts masses first :) -Tony - Do you Yahoo!?

Re: flow control decision making
I have been working on a series of pages that follow a guided tour approach where the logic used to determine the next routing may have not much to do with the updates that are performed by the action. The guided tour somewhat resembles a maze in a few places and sometimes relates to information gathered a few pages back in the tour. For instance, the business rules may say that after updating the database to say that you want Global Van Lines to move 5 boxes of stuff to the address XYZ, route to the data entry screen for customs form data for international moves, or route to the data entry page for moving stuff into temporary storage if that type of move was picked two pages back, or route the flow to the data entry page for moving a boat if that was the thing chosen to be moved 1 page back in the tour... etc. So the decision making for what the next page in the tour is has nothing to do with the action of updating the database with Global Van Lines and I would prefer to put the logic for it in a separate class with a whereNext() method that is executed if the Action passes... lets say... a null ActionForward AND a routing decision class is configured for the action. David Graham [EMAIL PROTECTED] wrote:I'm confused by your question. The value returned from an Action *is* an ActionForward. Actions are already simply routing logic anyways.

Re: RE: RE: The right place/time to clean up a session before session tim e out, or user logoff
Vernon, Yes, there are some possible timing issues with using object references attached to the session in any class implementing HttpSessionBindingListener. I believe that the order which references are unbound is unpredictable. When I did this, I ran into the same problem and compromised by using a constructor that would copy any reference that I might need for the session, inside the class implementing HttpSessionBindingListener. But... from a bird's eye view of this issue, I see that MVC, as used with servlet programming, appears to not be a complete solution for creating actions that are generated from clock events that need to interact with stateful data used by actions from user events. I would like to see a way to reuse a Struts action by a listener, etc. and set it up all within the struts_config. I do not want to turn Struts into daemon or anything like that. But it would be nice if it's footprint of responsibility might cover some of these other events that are not strictly MVC-user requests. -Tony Vernon Wu wrote: Jason, Now, I see what you're doing here. Rather than calling the session invalidate method in the log off, you call the method to clean up the session. That is some thought. I, however, think there shall be a more straight forward solution than twise thing around by the servlet desing. Thanks for explaining your solution.

RE: Ending a Session After Browser Has Gone Away
I'm not sure if this helps, but... If the users use the File-New-Window on the browser, they will have multiple windows to the same session... but if they create a new instance of the browser (ie. clicking on the icon), these will be totally separate sessions where the user will have to identify their selves in some way... if you are not adversed to cookies, (long term cookies that is), you could stash the user's identifier there... but I hate cookies... sorry I mentioned it. :) Cohan, Sean wrote:We must be stateful. This not an internet application (although it will be used across the internet.) It's an enterprise app and we must use state. Also, the users have requested they be able to use multiple browsers and won't want to log into to each one. I looked at HttpSessionBindingListener but didn't get a real good feel for how it can help us when the browser (or I should say when all browsers) have gone away and the user needs to log back in. Note: we flip a logged in flag during the login process to prevent the user from logging in twice. This gets flipped back when the user logs off or the session expires. This flag will prevent the user from logging back in, unless we can somehow get around cases where they've exited without logging out. I'm sure this is an age old browser problem and I'm sure there have been good solutions to getting around this. So I'm hoping someone can steer me in the right direction.

Re: how to detect when the user presses the stop button
This is a browser client and JavaScript question unless you are using an applet with an open connection to your server. You may want to redirect the question to the Mozilla org. The browser folks have not built in detection of those window component events on an individual basis except for general onClose purposes. There might be some tricks you can do with the mouse x and y to determine if the click was out of the regular screen area but this is cowboy hack and may not work for both IE and Netscape.

Re: how to detect when the user presses the stop button
On an associated topic... When someone clicks the browser stop button and the session eventually times out, I have in the past implemented HttpSessionBindingListener on a special class used just for cleaning up the database/ejbs and attached an instance to the session in an overridden ActionServlet when a new session is detected. Is there another way of doing this... Or something that I have overlooked in Struts. Craig R.

The answer is that, assuming the page they are waiting to load is printing things out, you will get an IOException when you try to send output. AFAIK, this is the only way to detect it. About the best you can hope for is that you *may* get an IOException -- there are no guarantees. Two cases where you definitely won't: * When the response content is small enough to fit into the response buffer, and you didn't flush it before returning from the servlet's doGet() or doPost() method -- the container might encounter a problem when it flushes, but it's too late for your application to hear about it. * When your client is conencted to you via a proxy server (or something like the Apache-Tomcat web connector), where there is an intermediary involved -- unless the intermediary is designed to forward a disconnect notification in some manner that your servlet container understands (and, for HTTP proxies, there's basically nothing like this). This is one of the issues that makes programming web apps quite interesting ...

Re: Struts Vs. Sun J2EE Compliance and Design Patterns
The pre-release Chapter 1 of Chuck's book has a section on this... about 15 pages down or so and explains the syndrome that your ex-colleague is demonstrating. ...Tell him that it's curable though :) Juan Alvarado (Struts List) wrote: Hello folks: Recently I had a discussion with an ex-colleague of mine regarding struts. I explained to him that it's an awesome framework and that it has everything for developing web applications using MVC. His response was something to the effect of I'm sure struts is great but we are very happy with our architecture here and that it has all the benefits of struts and that they are 100% J2EE compliant and sun pattern compliant and blah blah blah He also made it a point to point out that his architecture is just J2EE and no third party libraries. I tried telling him that struts was all J2EE also and that it was written in pure java. His response was that it was a third party package on top of J2EE. He then tried to tell me what patterns he uses for his architecture and those consisted of: Service to Work, with Servlet Front Strategy, Displatcher in Controller Strategy, and JSP View Strategy, Value Objects,and Data Access Objects. I tried to tell him that all that was nice and dandy, but with struts he could use all those patterns with struts and in the process save himself a ton of time in developing his application(s). Basically this was his response: I'm just against anything other than the base stuff. I don't like reallying on any pieces that are from other parties or that put layers on top of Java... to be honest, I'm just not interested. I'm sure that many of the people on there will have lots to say about why struts is great, but I already looked into it, along with all other options, and saw no benefits beyond adopting J2EE and Sun's core J2EE patterns. There isn't anything struts does that our architecture now doesn't do, and it doesn't do it any easier, so why would I bother? So my question is as follows... Isn't this person wrong in saying that struts puts layers on top of Java and that struts doesn't do anything easier than his sun based architecture?? If that was the case, why aren't we using his architecture/framework?? I mean as far as I know, sun doesn't have anything close to what struts is, and if truth be told, aren't they(Sun) using at least one of the struts creators for their own Java Server Faces framework. I would love to hear what the community's reaction to these comments are.
