html:javascript simple question
Hi,
In my jsp's i do on the bottom of the jsp:
script
today();
/script
In my head section i then define the method...
function today(){
var today = new Date();
var month = today.getMonth()+1;
var year = today.getYear();
var day = today.getDate();
if(day10) day = 0 + day;
if(month10) month= 0 + month ;
if(year1000) year+=1900;
var date=day + / + month + / + year;
window.document.forms[0]'shipments.shipmentDate'].value=date;
}
This is working fine, but thaught might there be a better way doing this ? Using
html:javascript ?
Thanks !!

RE: html:javascript simple question
Or with JSTL:
%@ taglib prefix=fmt uri=http://java.sun.com/jstl/fmt; %
jsp:useBean id=today class=java.util.Date/
script type=text/javascript language=javascript
!--
function today() {
var date = fmt:formatDate value=${today} pattern=dd/MM//;
window.document.forms[0]['shipments.shipmentDate'].value = date;
}
// --
/script
But seeing as how this is a Struts list, why not handle it in ActionForm.reset
(or wherever else you might be initializing the form's data)?

Simple Question about Long property
I have a form with a Long property; I used Long instead of long to have the property nullable, but if the (html) form includes such a property, struts sets the corresponding bean property to 0, even if it has no value (value=); what I'd like is struts to leave the property at null!! It also behaves so if the (html) property has non numeric value!! Any help is appreciated Renato Renato Romano Sistemi e Telematica S.p.A.

Re: simple question
Here are some random guesses.. Looks like it should work to me.
I use
html-el:form action=${url}
usually url is defined in a tiles def but what you're doing should work
fine..
what about
c:set var=url value=/foo.do /
to test if its some problem with the bean:define tag you could try.
%
java.lang.String url = /foo.do;
pageContext.setAttribute(url,url);
%
or perhaps your container is storing your variable as an object. so
html:form action=%= url.toString() %
Cheers Mark

Nothing to add really just a few variations on a theme.
c:forEach var=num begin=0 end=999
html-el:option value=${num}
c:out value=${num} /
/html-el:option
/c:forEach
i think
c:forEach var=num begin=0 end=999
htmll:option value=%= num %%= num % //html:option
/c:forEach
will also work although perhaps you need to convert the int to a string.

I know the question is targeted at doing this in a JSP, but why wouldn't you
just set up a String[100] in application scope, name it numbers (or whatever)

simple question
Hi all, I think I have a relative easy question. I have a J2EE application which has some entitybeans. I want to display the values of these entitybeans in my JSP pages (using Struts). I have made value objects of the entitybeans. In my ListAllCategoriesAction.java, I do something like the following: Collection allCategories = mySessionFacade.getAllCategories(); DisplayBean displayBean = new DisplayBean(); displayBean.setCategories(allCategories); request.setAttribute(categories, displayBean); return mapping.findforward( SUCCESS ); As you can see I'm using a special bean (displayBean) to pass the categories to my JSP page. In my JSP page I use the logic:iterate tags to iterate through te collection and display the proper information. Is this a normal / good approach? Or do I have to use ActionForm classes for this purpose? Thanks a lot, Harm de Laat Informatiefabriek The Netherlands - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: simple question
Yes. This is a normal approach. ActionForms are used only if you want to pre-populate data. i.e If you have to show default values in a text field you can pre-populate the Action Form and forward to a JSP. You can also store a Collection directly in one of the scopes and show that but Custom beans like this are useful because they can be manipulated quite well with the tag handlers.

What you are doing should be fine (as long as your collection is not too terribly big).

In my JSP page I use the logic:iterate tags to iterate through te collection and display the proper information. Is this a normal / good approach? Or do I have to use ActionForm classes for this purpose?

simple question
Hi, there is a possibility to send an object in the request if i don't pass it with parameter of the link? for example: % request.setAttribute(in,index); % ... hm:link page=/index.jsp transaction=true home /hm:link this obviously don't work...but there is a system to obtain this whit a Struts component? I should pass a String value to action, but this must be not visible in the url. In particular my action don't know the page that call it and for this... I try to pass it as message, but this don't work.. Any idea? Thanks in advance Alessio - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: simple question
You can try this : form name=myLink action=html:rewrite page=/index.jsp/ method=POST input type=hidden name=in value=... /form a href=javascript:document.forms.myLink.submit()home/a Notice the (not visible) HTML form will add a visual line break in browser. You can avoid it by putting it a page bottom or in an hidden div, or between two rows of a table.

Re: simple question
You don't need an ActionForm (but you can). You can use request.getParameter(in) in your action, you can use a dynaForm too if you don't wan't to create a formBean for this. As you can read in the code I sent, I did not used html:form, so action form definition is not needed. This beeing said, using a dynaForm an struts tags would be IMHO the cleaner way, and you will not have to create the code for a new formbean. Nico.

RE: [XEN] Simple question: forward and redirect
I hope to be not too much oot :-) I would even say that the forward is internal to the server (ie, no client/server communication) but the redirect is a http response to the client. The forward is sometimes used to separate the business logic (p.ex : a servlet) from the presentation (p.ex : a jsp). A problem can be if the servlet and the jsp sit in different directories. For example : a client accesses a servlet in x.com/servlet/frontcontroller that forwards to /gui/screen1.jsp. The client's path is still x.com/servlet/frontcontroller since the forward is internal. If the jsp needs to get a picture in /gui/image.gif then the html must look like img src=../gui/image.gif even if the jsp and the image are in the same directory. The redirect can be used for non-existing pages (p.ex : x.com - x.com/index.html), but there are other uses probably... A forward cannot go out of the application server since it is internal. The application server is not a proxy... Have a look at HttpRequest.getDispatcher(...) and HttpResponse.sendRedirect(...).

RE: html-el:link and logic-el:iterate and tiles --- Just a simple question.
Thanks that was what I was missing...
I ended up with: html-el:link page=${item.link} jsp:getProperty
name=item property=value//html-el:link
Last questions is the jsp:getProperty needed? I was hoping to find a
html-el:link / implementation that Produced Aproduced text/A.. Is
that possible?
Second question is how do I test for the last instance of item within
the iterate tag?

RE: Simple Question
Without a request instance, you'd be confined to accessing only the default bundle for the default module - a little limiting.

Since 1.1b1, the instance of MessageResources that you need is set in the request (under Action.MESSAGES_KEY) during request processing. The current subapp and message-resources key are used to decide which one to set. So, you will need access to the request in order to retrieve the correct instance.

Simple question about Struts
Hi all, I've studiing Struts for the past 3 weeks because I have done a generic Jsp content-management web site connected on a MySql database using a set of custom tag libraries following the Manning book Tag Librairies. So I am still new at Struts, and I would like a simple advice over the Struts framework. I was hoping to adapt my site to a Struts framework to gain some architectural strenght and, by re-using the work I've done with Strut, I thaught, limit the future development when doing another site with the same framework. My question is : Can a Strut web site be modify or upgrade without the outcome of a java programmers? I means without the creation of multiple java classes? It seems that if you want to add a page, or modify the parameter or the validation of a form, you must go into the java classes that controle this form and add some logic into it. Without questioning the strength of MVC, in a first glance, it seems that this framework is not light-weight and demands some real professional effort to adapt or modifie any web solution using this structure. So, maybe, loosing the goal of building a generic solution? By the way, I think I have having a virus a day (just got one) with this mailing list, nobody scan the mail before sending it?

Having trouble nesting iterate tags (long explanation,relatively simple question)
Hi. I'm fairly new to Struts, but I've gone through the Struts documentation
and KeyboardMonkey's helpful tutorial. What I want to do is (almost) right
out of the tutorial, but it's not working the way I would expect.
The list archives show that other people have had this problem, and the few
real solutions I've found seem to indicate that I'm doing the right thing,
but I keep getting exceptions. My understanding is complicated by the fact
that the tutorial shows how to nest lists within a form, but I'm not using a
form (surely that's not necessary?).
One clarification I need: the KM tutorial indicates that only Object[] can
be used for nested lists, even though the Struts taglib docs say that
logic:iterate can iterate over Collection, Enumerations, arrays, etc. Is
that still true? Or can I nest lists where the bean property getters return
java.util.Collection?
So let me describe what I have, and what I'm trying to do. BTW, simply using
a single-level logic:iterate tag works great. I'm using Tomcat 4.0.4b2
and the nightly build of Struts from a couple days ago.
I have a set of Locations that are in a City. I have a list of Cities. I
would like to list all the Cities, and under each City list all the
locations. My code manages to list all the Cities, but when I add tags
HTML to list the Locations, I get variously tag nesting exceptions or null
pointer exceptions (and occasionally a getter not found exception),
depending on various ways of writing the code.
I have a City bean (called a Site for historical reasons, it will
eventually be changed) defined like this:
public class Site {
public StringgetCity() { return mCity; }
public voidsetCity(String inCity) { mCity = inCity; }
public StringgetState() { return mState; }
public voidsetState(String inState) { mState = inState; }
public CollectiongetLocations() { return mLocations; }
public voidsetLocations(Collection inLocations) { mLocations
= inLocations; }
private StringmCity = null;
privateStringmState = null;
privateCollectionmLocations = null; // Vector of Locations
}
and a FindResults bean defined like this:
public class FindResults {
public CollectiongetCities() { return mCities; }
public voidsetCities(Collection inCities) { mCities =
inCities; }
private CollectionmCities; // A Vector of Sites
}
There's also a simple Location bean:
public Location {
public String getName() { return mName; }
public void setName(String inName) { mName = inName; }
}
As a result of submitting a form, my FindAction object gets executed. It
takes the form input, does a JDBC lookup, then creates a FindResults bean
and puts it in the session state. The following (simplified) JSP displays
the list of cities satisfactorily:
%@ page contentType=text/html;charset=UTF-8 language=java %
%@ taglib uri=/WEB-INF/struts-bean.tld prefix=bean %
%@ taglib uri=/WEB-INF/struts-html.tld prefix=html %
%@ taglib uri=/WEB-INF/struts-logic.tld prefix=logic %
%@ taglib uri=/WEB-INF/struts-nested.tld prefix=nested %
jsp:useBean id=findResults scope=session
type=com.latencyzero.cc.FindResults/
head
titleSearch Results/title
/head
body bgcolor=#ff
logic:iterate id=foundCity name=findResults property=cities
table
trtd
Locations in bean:write name=foundCity property=city/
/td/tr
trtd
!-- insert location list here --
/td/tr
/table
/logic:iterate
/body
/html:html
It's when I try to nest a list that I run into trouble. I started by
replacing the insert location list here comment with the following:
logic:iterate id=foundLocation name=foundCity property=locations
pbean:write name=foundLocation property=name/p
/logic:iterate
As soon as I do that, I get org.apache.jasper.compiler.ParseException: End
of content reached while more parsing required: tag nesting error?.
Various permutations of using nested instead of logic and bean result
in other errors. For example, if I use nested:iterate for the inner loop
(and on the bean write), I get null pointer exception (even if I remove the
'name=foundCity' attribute).
I even tried to make a single outer loop (the very first example above) that
used a nested:write tag, just to see if I could get *something* nested
going. Using both logic:iterate and nested:iterate, this resulted in a
null pointer exception.
Clearly, I'm missing some fundamental point about nesting. Some people's
responses on the list indicate that they've had success simply nesting
logic:iterate tags without trouble
(http://www.mail-archive.com/struts-user@jakarta.apache.org/msg23493.html).
I'd be happy with that for this situation (I don't think I need the
implicit-dotting of hierarchies of properties for this simple operation).
TIA for any help!
BTW, is my approach of

Does this tag exist architecture [was] This hopefully is a simple question that has been dealt with

Note that we only populate ML the fields we actually plan on displaying, since ML it is pointless to populate the other fields. Thanks for your feedback Larry. (By the way nice job on that AthensGroup paper on Struts if you wrote it). Currently I already have an EmployeeForm bean (all String fields) and an EmployeeBean (Strings, ints, etc.). The business tier does the DB query and returns an ArrayList of EmployeeBeans. Now the question becomes what next in order to iterate through this list and display the EmployeeBean fields in a nice way (ie. proper date format, currency format, etc.) ?... I'm assuming from your reply that you might have extra logic somewhere that will take that ArrayList of EmployeeBeans and loop through the list and populate a new List of EmployeeForm beans. In this step calls will be made to make sure the Strings in each EmployeeForm object are correctly formatted. I see how this idea will work, although it seems a shame that you have a perfectly good ArrayList of Employee objects and now you are iterating through it just to populate another ArrayList of Employee objects with all String fields. Before I looked into Struts I didn't see the big deal of iterating though this list of regular EmployeeBean objects and then where formatting was needed just call my helper util class to change the format. For example: %= RickUtils.displayDateAsString( bean.getBirthDate() ) % I know, everyone says the above it bad because you now have scriplets in your JSP code. Still, though, this seems to make more sense to me than to going through the overhead of looping through possibly a large ArrayList of beans in order to just populate a similar ArrayList with just String fields. I suppose I will go the later route in order to maintain the Struts architecture of perfectly clean JSP pages. Being new to struts and new to using tags, would it be that difficult to create a tag that when passed a double it new to spit out a display in some currency format or if it received a Date it would display it in the proper format. I noticed there is a tag library out there for display dates, but ideally I would like one tag that would just pick up the datatype and if datatype is double display this way, if Date display this way. Does a tag library like the above already exist? Thanks again for your feedback. I'm posting this to the list as well for any other ideas. ML There is a utility in Struts to help with this, but ML I have never used it, since it always seemed like ML learning to use it was more work than doing it ML manually.

Re: This hopefully is a simple question that has been dealt with
I haven't found the solution I will use yet to solve this problem in my own project, so advice would definitely be helpful. I found a taglibrary that purports to do this (at http://jsptags.com) http://www.sqlt.com/taglib.html I have not investigated using it just yet though. I think even writing one's own tag to format dates and numbers should be easy enough: just extend the bean:write tag to support a format attribute and use the existing java formatting capabilities (SimpleDateFormat, NumberFormat). Doing arbitrary String masking would be cool too (typical example is phone number formatting, currency formatting, but I also have additional requirements). Does anyone know of a taglib that does this kind of thing? Vlad Sorry to post this question again, but I'm still curious about this ...
