Re: anyone using Castor with Struts?
Hello John, We use Castor Struts in our projects. The right way to use Castor is to develop beans to work with entities from the problem domain, develop database structure and mapping configuration. And after that develop your Struts application. Struts' ActionForms are presentation specific classes - a some kind of informational proxy between entity beans and HTML form data from user input. Action classes incorporates business logic and work with Castor to take and store entity beans from/to persistence storage. I think that idea to use ActionForm as beans in Castor mapping is a potential source of problems. ActionForm must store field values between user submits and the best choice for type of properties in ActionForm is java.lang.String. Entity beans can contains any type properties and all values for it you can transfer from the ActionForm with help of BeanUtils.populate() method, which perform automatic conversion of the field values between String values and such types as Data, Integer and so on.

Re[2]: Includes and processing time
Hello Arron, There are some underground features... With static include we have one servlet for every page and for dynamic include we have one servlet plus additional servlets for every include. Every include page can be used in a number of pages so this code will processed by JIT as common used part of application. So, in some conditions dynamic include can be more preferable... Thursday, January 24, 2002, 4:40:04 PM, you wrote: A Actually... for performance, the first one is best. Why?... as when the A main page is compiled, the files included by this method are included as A if they were written in the one file, and then compiled. If a change is A made to the include, it wont be picked up unless the main page is A changed/recompiled for some reason. As it all ends up being the same A page, this is faster performance wise when everything is compiled and A dancing (CD? :). A For flexibility, the second. This method will create a servlet for each A include, and then pass the context from the first, to the included A second. Because the servlets have to pass the context and everything, A this is slower when everything is CD. The second can also be called A directly in its own right. A For my money, I usually go the first. Well, at least for any include A that wont be edited without being able to restart the server. If it A needs to be recompiled, you just touch the main page. A In some instances you need that second servlet. Why?... Java's spec A means that it will only take a compiled class up to 62K (If memory A serves. It's around there). Some pages we have to make can make this A quite easily once it's all said and done. So this means you have to use A the separate servlets. In one case I used the same include on multiple A pages by creating an empty wrapper JSP which would make another servlet, A and then include the static include like the other pages, and where A included use the dynamic include.

You can calculate query string for current page
%
String sourceURL = null;
StringBuffer URL = HttpUtils.getRequestURL(request);
String queryString = request.getQueryString();
if( (queryString!=null) (queryString.length()0) ) {
URL.append(?);
URL.append( queryString );
}
sourceURL = URL.toString();
%
for example. But this will work only if you call your page directly
and not use forward from action.
If you use forward (without redirect) then you must calculate path to
redisplay page in action class, store it in request scope and use this
string as parameter for language switch. Language switch action take
this query string and make forward to it after language switching.

Hi,
Is anyone using the STRUTS framework in a production environment yet?
We're currently developing a MVC based webapp and are looking at
potentially taking a step backwards and basing it around STRUTS. One area
of concern is the dynamic creation of the Action objects using 'forName'.
What sort of performance hit does this give?
Advice from our Tech Architect at the moment seems to be to look at STRUTS
but write our own version and he's not too keen on 'forName' processing.
Is this an unfounded concern?
CRM There are several considerations to think about in trying to address this
CRM concern:
CRM * How often does it happen? In Struts, objects are created
CRM dynamically only under the following circumstances:
CRM - The first time a particular Action class is accessed (so it's not
CRM really relevant to discussions about performance impacts).
CRM - When you are a using form bean, AND the form bean does not already
CRM exist in appropriate scope. If you adopt a pure MVC approach (and
CRM flow all your requests through the controller), you can easily
CRM arrange to create form bean instances from a recyclable pool if
CRM you want to.
CRM * Does it matter when it does happen? One of the most striking
CRM differences between modern HotSpot-based JVMs and earlier generations
CRM is that the cost of object creation (and the subsequent garbage
CRM collection) has been dramatically reduced. I have had people who are
CRM pretty sharp tell me that object pooling can easily cost you more
CRM performance than it saves by avoiding object creations, in many
CRM circumstances.
CRM * Is it worth the cost? The point of many features of Struts (or any
CRM other application framework) is to accelerate development, and to
CRM reduce ongoing maintenance costs by making your architecture naturally
CRM easier to maintain. Is this worth throwing a little extra hardware
CRM at the server to deal with any perceived overhead of object creation?
CRM For many people, the answer is yes, absolutely. And projections for
CRM the future cost of a developer's time, as compared to the cost of
CRM x MIPs worth of CPU time, is going to make this even more attractive.
CRM As you can see, there's no cut-and-dried answer. Dynamic object creation
CRM has a cost (which can be mitigated in your application design). So does
CRM introspection to do the BeanUtils.populate() trick of copying request
CRM parameters into bean properties (which vastly reduces the work needed to
CRM create and maintain form bean classes). Like everything, it's a balance
CRM of cost versus benefit. And the benefits can be quite dramatic.

Re[2]: Proposed feature: Bean property transformations
Hello Ted, Saturday, June 02, 2001, 1:30:00 AM, you wrote: TH Harris, Andrew S wrote: A component would be able to hold a text value and a data value. The text value could hold the value entered by the user, prior to validation, then this could be played back to the user if validation failed on that component. If validation succeeded, the data value would be updated, then the text value would be replaced by the formatted value, using the data value and the formatter. TH This is a good design pattern, and one we can use with Struts today. In TH the ActionForm bean, define two properties, one for the text value and TH one for the data value. If validation succeeds, convert the text value TH to the data value, and (optionally) update the text value to match your TH preferred formatting. TH Though, with a general conversion/transformation package, we would TH really only need to store the desired data value since we could TH transform it again later when the value was accessed for presentation, TH perhaps via a bean:writeTransform tag. What reason to store text values and data values in ActionForm? I think that more flexible approach is to use ActionForm with text only fields and data bean with native types, not String. In this case we can name all corresponded fields in data bean with same names as for ActionForm and use convert methods under it, for example, or use another convert methods. We can convert text values to/from with one of the ways - 1. Perform conversion of all fields in some method in ActionForm, for example import/export. 2. Make it in every setter/getter. 3. Write special helper class to perform conversion - in this case more flexible approach can be used - one helper can handle multiple sources and targets. -- Best regards, Olegmailto:[EMAIL PROTECTED]

I use next approach to support validation of int values.

Any exception in this stage will be processed and error will be stored in ActionErrors. With such scheme you can hold user's input and make stable conversion mechanism. KS Consider the following scenario : KS I have a form element "A" that can accept only integers. KS Corresponding to this property, I have a setA(int i) and getA() methods in my ActionForm. KS When the user enters a non-integer value for "A" and submits it, the ActionServlet populates the form and calls the validate method on my form bean KS (assuming my form is a validating type). KS I want to validate in my ActionForm if the value entered is an Integer and if not i want to populate an error message and have the original user KS entered text in place. KS - When I looked at the Struts code, I understand that when converting this property value to an Integer, if it hits a NumberFormatException, Struts KS replaces the value with "0" and calls the validate routine.
