Re: Feedback on Struts Pros and Cons
David Bueche [EMAIL PROTECTED] wrote: Struts Disadvantages: 1. Instead of direct dispatching by controller Servlet(s), dispatching is defined in an XML file, adding a layer of indirection overhead to the architecture. Do you really think, this is an disadvantage? 2. Requires behavior typically factored for commonality in controller Servlet methods to be duplicated in every Action subclass (some common behavior could possibly be delegated to additional classes or components and accessed by each Action subclass). There is still the possibility to subclass ActionServlet and so create own controller. 3. Struts internationalization is limited to static strings and does not include internationalization of data returned by a business component. A bit can be achieved with the placeholders in constant strings. 4. Struts internationalization requires an ApplicationResources.properties file, which conflicts with the current Enterprise Java Application Standard of definely properties directly in the web.xml file. Struts does not use ApplicationResources.properties as real properties. The file is used only as a handy tool for peristing string maps. In our projects we use database backed internationalization with struts. 5. Presentation of message collections is predefined in tag libraries (although these could be modified for more specialized presentation). 6. Requires understanding of custom tags and tag libraries, as well as their deployment. While this may not be a problem for more advanced developers, this will add another layer of complexity for less experienced development and support teams and requiring more intensive EAS involvement. 7. Delegating much of the presentation layer to custom tags can make the final HTML/presentation less clear than HTML placed directly in the JSPs/Servlets. 8. Delegating much of the presentation layer to custom tags can become a performance problem. -- gR -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

Re: dynamic forwards
lisa ward [EMAIL PROTECTED] Hi again, The values in your hash map have been hardcoded in, which works fine. But what do I if I do not know what the user's selection will be in advance. Take for instance, if I have a set of checkboxes on my page, I would like to be able to initialize the map with the values that the user has selected. Or am I just missing the point here? Hold on. You have to have all necessary information, when you are generating the link. It does not matter, whether the keys in the map are hardcoded or determined during the runtime. Important is that you are creating the link on the server side, before the user clicks on any checkboxes. If you want to use user's input, you can do it when serving the next page. You can then generate the map in an Action and generate the link for the next displayed page (so you will know all paramaters in advance, since the checkboxes have been submitted already) Or your Action can use the checkboxes to determine what to do or to determine where to forward to. You don't need to use constant strings in findForward. Another possibility would be using JavaScript on the client, but since many browsers have JavaScript disabled, you should not rely on it. -- gR Please explain further and thank you very much for your patience.

You can do something like this:
in your html.jsp:

TYPE=text/css
HREF='%= response.encodeURL(stylesheet.jsp) %'
and stylesheet.jsp would produce the generated stylesheet, something
like this:

Re: CachedRowSet or SQL, what is the best way?

I've been using straight JDBC calls, but it looks like CachedRowSet would be easier. Anyone know when it will be officially released? Is it currently stable? I use cached RowSets beacuse they hide the connections, SQL and the whole persistence stuff from the JSP which uses them. I only had problems with some Oracle specialities (nested ResultSets will not be serialized by the EarlyAccess version). Other option would be to use the Rowset which opens a life connection to the datasource. The Action would set up its properties and the RowSet would fetsch the data when needed in the JSP. The JSP has then to be responsible for closing teh RowSet (I always call rs.close() in the JSP, even though for the cached ones it is not necessary and it means I have to have scriplet in my JSP) I'd prefer the second option if the caching becomes too heavy burden for the memory.

Re: Including Actions via jsp:include
:-) The question is not, whether it works on different servers, the question is, whether the original including of forwarding Action works on some servers. If the Action.perform returns null, then there is no forward and no reason for such an exception. The real problem with this solution is that it breaks the MVC pattern. In order to make it work, your VIEW (your JSP) which includes the action, decides how to display the action's results. It does so by incluing the second *.jsp. But this decision should be made by the action itself in cooperation with the ActionServlet.

How to include an .do from a jsp
Hi all, some time ago I've written about my problem including *.do in jsps. E.g. in the template tags. The problem is caused be the way, how Action/ActionServlet controls the invocation of its view. The request is either forwarded or redirected to the view and neither forwarding nor redirecting work, when the action is included. My workaround is, to let the Action's perform() method to return null and then in my composite view include the sub-view. So something like: jsp:include page=thing.do / jsp:inlcude page=thing-success.jsp / This definitely breaks the MVC pattern, since the composite view controls the view of the sub-action. My proposal: Now I can specify in struts-config.xml that a forward should be redirected with redirect=true. What about allowing include as well? Even better would be, it ActionServlet recognised, the action is beeing included and it would include the view instead of forwarding/redirecting to it. I'll try to have a look at it in September and submit a patch. -- gR

Re: Dates and Struts
Matt Raible [EMAIL PROTECTED] wrote: Is it true that Struts cannot handle a java.sql.Date or java.util.Date datatype? I seem to get errors everytime I try to have one in my form. Thanks, Matt No it cannot. Date is not so easy to parse since it is locale dependent. Also the displaying a date is not easy. This brings me to one general architecture question: Where do you (I mean all struts users) put the formatting/parsing´of values? For display only data, I try to put it into the JSP (with custom tags). But what about the editable data? Is the ActionForm the right place? I store the data in non-string form (like Date) and the get/set methods operate with strings. The language dependent formats use an addiotional property locale which I set either in the reset() method (from request and session). It could be done simpler, I used only string aware ActionForms and the whole formatting were done in Action.perform, but this wouldn't be conform with the MVC pattern, woul'd it? -- gR

Re: form validation
Mike Dewhirst [EMAIL PROTECTED] How is it possible to validate input in struts for formatting? What I mean is, is it possible to check when a string is entered into an input field that populates an int? It seems that the Controller populates the int with a 0, which makes it difficult to detect if this was an invalid input, or a real 0. Would we need to extend the framework if we want to be able to detect this? Thanks for any advice!! You can either use String (in this way you can accept inputs like 2.001), or you can use Integer. It will be null, if no correct integer is has been entered. -- gR

Hi Fracois, so I've hacked a bit in the beanutils package and now struts does work perfectly with your string based properties. No need to change struts, it is enough to change beanutils.

I'll do it later if necessary) - I've changed the StringKeyedPropertyDestrciptor to inherit from PropertyDescriptor - made PropertyUtils getPropertyDescriptor to return it. - changed the method BeanProperties.populate Now I can use string keyed properties in Struts. The source code however is quite messy now. -- gR

Initializing Application Scope Attributes *.do in template:put
Hi, perhaps these are FAQ: 1) My application has menu structure configurable in the database. I want to read the structure from the database when the app starts and store it in an application scoped bean. To be able to read the data, I need a DataSource so I need access to actionServlet. What is the best way to do this? I know, I can use my own servlet inherited form ActionServlet - but is there any ohter, perhaps more configurable way? 2) When I need initiazed data in my application, I usually put the initialization into setServlet of the action which needs the data and I thought never to need to access such data from a JSP directly. But now I've found this problem when creating menus. I've created a MenuForm which holds the information about the current location id and a collection of menu's children. MenuAction reads the id and fills the children collection, checking whether the current user should see the menu items. menu.jsp then displays the menu structure from MenuForm. It works perfectly, till I try to put this menu into another JSP via jsp:include ... or template:put content=/menu.do?id=100 The problem is that my MenuAction does not produce the HTML, it *forwards* it to the menu.jsp. And forwardning seems to be forbidden inside an include. (Err: Cannot forward as OutputStream or Writer has already been obtained) Is there a way, how to include a *.do generated page which internally uses forward?

I've similar problems when I used the ActionForm for displaying read only properties which did not have an html:hidden on the jsp page. In request scope it works something like this: The ActionForm instace (A1) is used to fill jour JSP. A1 has been probably prepared by some Action. After delivering the response (JSP) the instace A1 is forgotten and eventually garbage collected. The teh user sumbits your JSP. New instace (A2) of your ActionForm is created and filled with the sumbitted values. If the countries list is neither filled in the reset() method, nor the constructor, nor the sumbitted HTTP parameters, than it might be empty or null. Because the instace A1 and A2 are different. If the form is in session scope, than A1 is preserved. -- gR
Nested classes
Hi all,
I am using an ActionForm with a collection of Rows which should be
editable.
My ActionForm contains a property getRow(int i) which returns a bean
with the row's properties.
Everything work perfectly, when the class returned from getRow(int) is
a standalone class. But as soon as I make this class a nested class
of my ActionForm, struts complains, if cannot find property setters:
This works:
public class MyForm ... {
public MyRow getRow(int i) {
...;
}
}
public class MyRow {
public setProperty(String value) {
...;
}
}
This does not: (cannot find property setter for row[0].property)
public class MyForm ... {
public MyRow getRow(int i) {
...;
}
public static class MyRow {
public setProperty(String value) {
...;
}
}
I'd really like to use nested classes. Is there a way?

Re: Updation using iterate tag

Hi All,
I have one form bean namely MyFormBean.
This bean contain vector (pricesVector) of class type Price.
The class Price has two attribute oldPrice and newPrice
I want to display prices vector in such fashion
-
oldprice1 (as label) newPrice1 (in text box)
oldprice2 (as label) newPrice2 (in text box)
oldprice2 (as label) newPrice2 (in text box)
-
How do I do this using iterate tag, so that any updation in text box should
get updated in the vector (prices)?
I tried using iterate tag but could not get through?
Anybody having solution for this.
1) You have to have two properties in your ActionForm:
public Collection getPrices();
and
public Price getPrice(int i);
Note: getPrice() should return valid Price even if the Vector does not
contain it.
it could look something like this:
public Price getPrice(int i) {
while (pricesVector.size() = i) {
pricesVector.add(new Price());
}
return pricesVector.get(i);
}
2)
your iterate tag could look something like this:
logic:iterate
name=editPricesForm property=prices
id=element indexId=i
type=Price
tr
tdbean:write name=element property=oldPrice //td
tdhtml:text property='%= price[ + i + ].newPrice %' /
html:hidden property='%= price[ + i + ].productID %' /
/td
/tr
/logic:iterate
You have to know, that the Vector will be FILLED (not just updated) when the
form is submitted.

Re: Iterate tag update
The problem is, the generated names of the HTML form elements do not
correspond to the names of properties of your ActionForm.
Here a sample, how this can be done:
logic:iterate name=myForm property=elements id=element indexId=i
type=de.grayman.test.struts.MyElement
tr
td
html:checkbox property='%= element[ + i + ].member %' /
html:hidden property='%= element[ + i + ].elementName %' /
/td
tdbean:write name=element property=elementName //td
tdbean:write name=element property=elementDescription //td
/tr
/logic:iterate
In the MyForm class, there have to be two properties (getter methods):
1) the collection elements
2) indexed property element
private Vector elements;
public Collection getElements() {
return this.elements;
}
public MyElement getElement(int i) {
while (getGroups().size() = i) {
this.element.add(new MyElement());
}
return (MyElement) this.elements.get(i);
}
Note: Class MyElement has read/write properties member, elementName,
elementDescription, ...
Note: The getElement(int i) fills the Vector with empty elements, if they do
not exist.
In this way, the form will be filled correcly from the submitted HTML-Form. Of
course,
you could use another approach, e.h. HashTable or an Array instead of Vector.

Hi,
I am using logic:iterate tag as follows to print a table with text
boxes.
logic:iterate id=product name=productSearchForm

filter=true/
/td
td align=center

I have a array of objets(Product) in productList. When I update the quantity
and submit the page, it does not update the information into the
productList.
What might be the problem???

I18n was: jsp vs do
Thanks, this can be the source of some problems I've had with the i18n. I am using Struts only about one month, I has some problems with figuring out, how bean:message determines the locale it should use. So I peeked in the sources and found out, it uses a session sttribute. I haven't look in the sources deep enough, so I did not find, who actually sets the session attribute. So I used a tiny scriplet which checks to see whether the attribute is set, and if it is not, the scriplet sets it according to the request's preferences. I mean, this could/should be done by the bean:message tag as well. -- gR - Original Message - Timothy Shadel [EMAIL PROTECTED] wrote: One thing to note, however, is that the internationalization (bean:message tags) won't go to non-default mappings unless you use a *.do extension.

If you need to make your login screen available (to continue the example) in several languages, you need to link to the *.do version, and write your Action class in a way that either won't auto-validate the ActionForm, or won't require info up front.

template and I18N
Hi all,
I've just started to use Struts and I have some questions:
1. How can I use the I18N features in the template tags?
In my template.jsp I've got the following tag:
titletemplate:get name='title'//title
In the page using this teplate the following:
template:put name='title' content='Kalkulation' direct='true'/
I'd like to replace the German text 'Kalkulation' with its
key e.g. 'app.title.calculation' Is there a nice way to do this?
2. How can I use use the I18N features in Struts directly
in Java Scriplets?
Sometimes I need the translated texts in scriplets. What is
the best way to access them?
Now I am using this aproach:
%
MessageResources resources =
(MessageResources) pageContext.getAttribute(
Action.MESSAGES_KEY, PageContext.APPLICATION_SCOPE);
Locale locale =
(Locale) pageContext.getAttribute(
Action.LOCALE_KEY, PageContext.SESSION_SCOPE);
if (null == locale) {
locale = request.getLocale();
}
String myText = resources.getMessage(locale, app.the.text,key);
%
Thanks for an answer
