I think Struts is a really nice implementation of MVC. It's certainly a lot quicker and easier to use than writing one yourself - I know, I've done both!
If you have a specific question relating to Struts, I'll try to answer it.

Reply 3 of 39 I'd like to use struts instead of petstore for my future application. The only problem is the implementation of an EJB framework on struts. You have to do it by yourself, and perhaps it could be too slow to implement!
Let me know your experience.
thanx

Reply 4 of 39 I work in an environment where we must use STRUTS. My personal opinion of it is that it is worthless.
Keep in mind, I prefer system performance over anything else, and STRUTS does add overhead.
In my opinion, STRUTS is smoke and mirrors. Instead of using the HttpRequest object to look for parameters, STRUTS requires that you build and object that extends the ActionForm (if I have the wrong name, please correct me). The set methods in this form must match the name of the parameter coming in (a TextBox with the name jimbo will only be set in a object with a setJimbo() method). Now, regardless of if you use the Request object or STRUTS form, you still need to know the names of the parameters you are looking for.
STRUTS then forwards the ActionForm to an Action. This is for the work you want to do. A Servlet calls the doPost/doGet to do this.
STRUTS allows for a Mapping type structure. Using a return value from the logic you've coded, it determines which JSP page to forward the request to. This can be done very easy without STRUTS.
In my opinion, it is MUCH better to learn the Java Servlet specs instead of STRUTS. The arguement for using STRUTS is that it gives you an MVC environment. If you think about this, the Servlet Container gives this to you already. The client (Brower) is the view. Only the HTML/WML you send is seen by the client. JSPs where created just for this purpose. The web container and servlets you develop are the controller. When you deploy a servlet, you can configure the URL or URL pattern that servlet will answer for. Servlets should only verify the incoming data and prepare the outgoing data. The JSP (view) will take that data and format it for the client. The Model is of course any data (usually a JDBC Database) that is used to perform the requested logic.
Why this needs to be changed is beyond me, especially considering the Servlet spec provides for everything you should need.

Reply 5 of 39 I agree with you Ken, 100%
I am currently involved in building reusable frameworks for our web infrastructure. One of these frameworks is a template implemenetation of the Front Controller pattern. I thought about using Struts instead of writing the code myself, but since Struts is not a standard, and, not to mention, implementing Front Controller is not very difficult, I choose to write the framework instead.
I'm a firm believer in using frameworks, but there are some that are worthless, such as Struts. The overhead involved in learning Struts and customizing it for your environment can be spent writing the entire framework yourself. You will also learn much more about the Servlet API, as Ken mentioned, if you write the framework yourself.
Even though Struts is 100% Java, it's still a 3rd party proprietary API, which means that if you implement it, your are dependent on it. Always stick to standards.

Reply 6 of 39 While struts is a 3rd party API, I would not be suprised if it became part of the J2EE servlet, JSP specification.

Reply 7 of 39 Why would you be surprised if STRUTS became a standard?
Everything STRUTS allows you to do can already be done. Why would SUN add the overhead of STRUTS while adding no new functionality?
Learn the Servlet/JSP specification, you'll be MUCH better off.

Reply 9 of 39 Ken, i wouldn't call Struts worthless. It depends on what you're trying to do and what skills you're having in your company. While Struts is definitely useful for your web-centric applications, you'll need something else for your EJB-centric applications. While servlets are cool, i'm very happy with Struts' form handling. If you prefer system performance over anything else, you'll almost always end up writing something by yourself. But what about contributing your performance tipps to the Struts developers?
SAF, i have to disagree with your 'The overhead involved in learning Struts and customizing it for your environment can be spent writing the entire framework yourself.' For me this was simply not true. When i started with Struts, it was somewhat difficult to get recent documentation but this has changed. If you have a look at the Struts resources, you'll find a bunch of articles, papers and the like. For 3rd party proprietary APIs: the Apache Software Foundation develops Struts, not somebody as proprietary as for example Microsoft. Struts lead developer is a member of JSR052 and you get the full source code.
'Everything STRUTS allows you to do can already be done.' Well, everything Java allows you to do can already be done with C++. So why not stick with this ISO standard?
And finally: this is version 1.0! Not much other software is that useful in such an early release. I'm personally very happy with Struts and recommend it for web-centric applications.

Reply 10 of 39 If it where my money I was spending to build an app, I would no doubt require that the J2EE servlet spec be used.
In my opinion, any java web developer worth their weight will know servlets. This gives me a larger pool of talent to select from and allows for zero time training on a internal/3rd party API.
I believe that there is ZERO reason to build a 'framework'. Again, I think the Servlet API is more than what is needed.
Sometimes I think people get sucked into the idea of following certain buzzwords like 'pattern' and 'framework'. EVERY application will have it's own requirments. I want to hire the person who can look at a set of requirements and build an app using industry standard tools.
Just because you CAN fit an app into a pattern does not say you SHOULD make it fit a pattern.
As for frameworks, the application itself should dictate how it is built. Too many times I have seen a simple problem solved in a way to requires too much overhead, just to conform to the current 'framework'. Frameworks should only be used when they lower development/training time, not just to have one.

Reply 11 of 39 ken, i agree with you that frameworks, patterns and the like can be used and abused (which applies to every technology, of course). One should only use a framework if it helps to solve the task at hand. And yes, servlets are essential for web development. Anyway, i'll continue to have a look at frameworks and patterns and i encourage everybody to do the same. They give us something to think about, even if we don't use them.

I think most Enterprises currently working in J2EE, roll their own J2EE frameworks. (I'm on my second), this is mainly because Struts is only just becoming complete. I think that in the future this is likely to change with a lot of late adoptors of J2EE starting to use Struts.

Hrm, object-oriented programming has promised code-reuse for years now (or was that decades?), but still fails. When will this dream come true? Anyway, i'm having the impression that code-reuse works better for Java as for C++.
Thank god we're already in the 'post OOP era' and we're now entering the 'component-oriented programming era' which will do better, of course
