Dynamic Layouts in Tiles
Is there any reason why I cannot use the names in tiles definitions in tiles-def.xml as the reference in forwards inside Action subclasses? Can I just use "return (new ActionForward([NAME OF TILES DEFINITION]));" rather than, e.g., " return (new ActionForward(mapping.getInput()));"?

Re: Tags creating Tags
Hi Lukas,
If I understand you correctly you need to look into the pushBody and
popBody methods on PageContext. Basically, in doStartTag(), call
pageContext.pushBody() then in doEndTag() you call
pageContext.popBody(), retrieve the BodyContent's value, muck about with
it to your heart's content, then output your transformed markup to the
current JspWriter.
Something like that anyway. This is off the top of my head so I may be
remembering the semantics slightly wrong, but I've definitely done this
before
class MyTag extends BodyTagSupport {
public int doStartTag() {
pageContext.pushBody();
return EVAL_BODY_INCLUDE;
}
public int doEndTag() {
pageContext.popBody();
String transformedMarkup =
doSomeTransformations(getBodyContent().getString());
pageContext.getOut().print(transformedMarkup);
return EVAL_PAGE;
}
}
Hope that helps,
Mark

I've thought about trying to extend BodyTagSupport, return
EVAL_BODY_BUFFERED in doStartTag(), modify the bodyContent in doAfterBody(),

Index properties (once again)
Hello sorry for posting the same question again and again. But I seem to
have gained something on this. Now I have a few (more) questions. Maybe
someone could help me figure out what or where I am getting it wrong.
This is the case. I have a product, with different states(checbox) and
each state has to have a bidAmount (text area) and a transaction
type(radio button). I want the form to be generated such that for
validation.
a. I can check If the checkbox(for the state) has been checked the
bidAmount and transaction type has been selected.
Now my question is,
a. in the action form. Do I need to defind the bidAmount as an array
b. I didn't know about this until know, but are only String type allowed
in actionform ( ihavent read about this anywhere except on one of the
posts in this mailing list)
c. I have set the setter and getter for (lets take the example of
bidAmount only) like this.
public String getBidAmount(int index) {
String tmp = new String();
System.err.println("Value of index: " + index);
try {
tmp = bidAmount[index];
} catch (Exception e) {
System.err.println("Error: " + e.getMessage());
}
return tmp;
}
public void setBidAmount(int index, String value) {
System.err.println("index: " + index);
System.err.println("Value: " + value);
System.err.println("--");
this.bidAmount[index] = value;
}
And the corresponding jsp tags as follows.
BC
| SC
I know the the inline scriptlet is very ugly, but this was the only way
I could get it to call the index number in the getter method. However
the desperate attempt (try and catch) makes the form work (not much use)
I cant get the the setter to set the values in the individual array, and
get a stack trace error instead.
I am not really sure where Is wrong and non or the documentataion define
things very clearly (or maybe I am poor in comprehension)
Apologies again to people who think I am bothering them by posting again
and again, but this is my last hope!!
Hope someone helps!
(ps: once I am through with this, I shall write my own HOW TO for the
indexed properties and its use)

Lukas Bradley wrote: Ruth, Craig, and lurkers, I think what I'm after boils down to a method like this: public String renderTag(PageContext pPageContext, Tag pTagToRender) throws JspException A look at the JSP Specification will tell you that this would not work at all for a classic tag handler (i.e. implements Tag or implements BodyTag). After creating the tag manually, you could pass it to this method, and have it rendered. The return value of a String should be the final output of the Tag. The method would check for BodyTag, IterationTag, etc support, and react to it. This way, the user could embed custom tags (Struts or otherwise) within their own custom tags. I'm surprised a method like this doesn't already exist. This wouldn't be recursive, nor would it recompile on each shot. You may be right in calling this a tad "hackish," but it would be useful, no? I can even think of another method that would be the incredi-hack: public String renderTag(PageContext pPageContext, Tag pTagToRender) throws JspException Where you pass in "" instead of the Tag object itself. Now that would be aggressive. For another approach, the JspFragment interface looks promising. However, I'm stuck with Tomcat 4.1 for now, so JSP 2.0 is out. I think the approach you suggest is problematic, for many of the reasons that Action chaining is problematic. The most serious issue is that you're trying to use a JSP artifact (a custom tag implementation class) for something it was never designed to do (be a reusable "output generator" outside the context of the very strict and complex lifecycle for tag instances described in the JSP specfiication). "Hackish" does not begin to describe how much trouble this kind of anti-object-oriented approach will lead you to in the long run. The right answer would be to create your own tag class that does exactly what you want. If your tag wants to leverage functionality from existing tag classes (and you don't want to cut-n-paste), either make your class a subclass of the existing one (presuming the stuff you need is already abstracted into useful protected methods), or abstract the stuff you need into utility classes that can be shared between your tag and the standard ones, and then lobby to have the same factoring done in the standard classes. This is the foundational basis on which all Struts tag classes are organized, and has proven to support a pretty rich library of tag class implementations that (in many cases) reuse or specialize protected methods in their subclasses. In no case was a "generate a tag" type of hack considered, because it's not necessary. All that's necessary is applying sound design practices for factoring reusable code into reusable chunks. I won't try to claim that we've done a perfect job at the current factoring, but the existence of something like struts-el (which was basically built on top of the existing tags, without having to rip them apart) is pretty good evidence that we're on the right track. Trying to interfere with the tag instance lifecycle that the JSP page compiler assumes pretty much guarantees you'll end up with disaster.

Re: Tags creating Tags
I apologize for the original cross-post. I was hoping there might be a Struts method to do what I wanted. Here is something I wrote to the other group, after a post from Felipe Leme. > I think you can accomplish what you're looking for using JSP 2.0 and tag > files. Yep. That's exactly what I'm looking for. Now Tomcat 5 just needs to be released, because I'm stuck with JSP 1.2 for now. *sniff* Thanks for the help everyone. I'm including a snippet from the JSP 2.0 PFD 3. Lukas JSP.8.1 Overview As of JSP version 2.0, the JSP Compiler is required to recognize tag files. A tag file is a source file that provides a way for a page author to abstract a segment of JSP code and make it reusable via a custom action. Tag files allow a JSP page author to create tag libraries using JSP syntax. This means that page authors no longer need to know Java or ask someone who knows Java to write a tag extension. Even for page authors or tag library developers who know Java, writing tag files is more convenient when developing tags that primarily output template text. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Multiple parameters
Rajat, Perhaps I'm missing something here, but by definition, one of your radio buttons should be checked. If you display your form without having any of your radio buttons checked, then it amounts to a checkbox. If you initialize your form bean correctly, one will be checked and then, you shouldn't need to validate the radio button at all.

Re: Indexed properties help!
Rajat,
Here is an example of an indexed property called 'signal' (in my
application it holds complex objects, not simple strings or integers):
public OrderedSignalBean getSignal(int index) {
while( index >= this.getSignals().size() ){
this.getSignals().add(new OrderedSignalBean());
}
return (OrderedSignalBean) this.getSignals().get(index);
}
public void setSignal(int index, OrderedSignalBean signal) {
while ( index >= signals.size() ){
signals.add(new OrderedSignalBean());
}
signals.set(index, signal);
}
The 'signals' member is private and is of type 'ArrayList'. It is
created in the form's contructor and the reset method of the form :
signals = new ArrayList().
The setter and getter methods of the indexed property perform so-clled
"lazy-initialization" so you do not have to worry about the siez of the
array list.
Hope this helps.

What is the purpose of this confirmation page? Is this just a display of
what the user has just entered and asking the user if it is ok to submit
now? If the user is happy with the input, (s)he is supposed to click on a
"Done" button and if not, (s)he clicks on a "Cancel" button. Is this
correct? If so, forget about the Javascript, use ordinary Actions to
direct the user to the correct place. and you can just use the
> 4) On confirmation page, the user clicks "Done" button

I assume the user is redirected to index.jsp only if there are no errors?
and you are using the form bean validate for checking input errors and so
on. What do you mean to do if there are no input errors but for some
reason the registration is a failure (as in database is done etc.?)

This is wierd. Seems like your onClick method isn't working correctly.
Have you looked at the source of the regisration page? Have you checked
for javascript errors? You could change you confirmSubmit() function so
that all it does is throw an alert so that you know that onClick is
working if you really want to dig into this. On the other hand, if your
specs are such that (as I suspect) Javascript will not even be needed any
more, maybe you can do away with this whole code anyway..

how you get the validate function to check if you entered a float value
or not.

I think ActionForm beans accept only String values. It's up to you to do

Indexed properties help!
Hello, I am pasting some excepts from the struts documentation. It would be really great if someone could help me clear this. Question 1: The "indexed tags" feature is provided by several tags that have an optional boolean "indexed" attribute. This is only legal when inside a "" tag. When the "indexed" attribute is true, then the tag will incorporate the loop index into the resulting HTML component. The several tags that support the "indexed" attribute can be broken into three groups, split by what they do to incorporate the loop index into the resulting HTML component. Group 1 Group 2 Group 3 checkboxbutton link fileimage hidden submit password radio select text textarea In Group 1, all of these tags will generate an HTML "name" attribute of "name[nn].property". The value of each tag will also be initialized by the getter method corresponding to that property specification. So if I have name[nn].property, that essentially means I am creating an array of the form. But what I really need is an array of property, instead of the bean. Question 2: How should the property be declared in the the actionForm if it has to receive an array of information. thanks Rajat Pandit | [EMAIL PROTECTED] +91 612 3117606 [ Developer and Part Time Human Being] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Multiple parameters
Its certainly the case with dynaforms, that life is easier just to have
everything as strings including any nested beans..
I'd stick to strings, and perhaps organise things so you have a bid
object that you nest in your form.
this would result you being less confused.
By your question I guess that your bid object class is part of you
object model (stuff from db in this case)
If you using 1.1 here's how i'd be thinking about the problem..
[if you know how big you array is going to be define here, else just
scope the form to session.
..
a bid bean
..
public class BidBean {
private String amount;
public String getAmount() {
return amount;
}
public void setAmount(String str) {
this.amount = str;
}
}
..
ArrayList bidList = new ArrayList();
bidList.add(new BidBean());
theForm.set("bid",bidList);
request.setAttribute("bid",bidList.toArray());
..
..
Assuming you've an existing om and thats why you seem a little concrete
in your thinking, here's where to think about bringing stuff together.
..
DynaActionForm theForm = (DynaActionForm) form;
ArrayList bidList = (ArrayList) theForm.get("bid");
for(int i = 0;i < bidList.szie();i++) {
BidBean bid = (BidBean) bidList.get(i);
.. now copy the properties to your model classes. You'll need to change
strings to floats etc. and set the values accordingly
}
..
when your action servlets get kinda long, you start moving this sort of
thing out to your model layer.
Cheers Mark

RE: Indexed properties help!
Looks OK.
However, I would not use a basic array (private members) but ArrayList,
HashMap or LinkedList, etc.
I did not manage to have arrays working (the lazy initialization
failed).
You will have problems in JSPs.

Tags creating Tags
Hi all, Maybe I'm just tired, but the answer to this is not to be found. I could me making this harder than it is, or something might be right in front of me, and I don't see it. What I want is a custom tag that creates other custom tags. Here is a simple example: Should produce something like this: English Which should then evaluate to: English I've thought about trying to extend BodyTagSupport, return EVAL_BODY_BUFFERED in doStartTag(), modify the bodyContent in doAfterBody(), then return EVAL_PAGE() in doEndTag(). However, BodyContent has a protected constructor, and no way to set its content. I want to maintain the functionality gained from Struts-like custom tags, while extracting the creation of them in a super-duper momma tag. Any help?

Re: Tiles And Images
Using the tag is powerful, though, as it allows you to use relative (to page) references for links/images/etc. - if needed, and module relative references are still supported by , , and of course, tags. That's how our application is structured - this way, when we put things in different directories, and each of those directories has its own images directory, so we can use the same tile or JSP in each of those directories and have them use relative image paths, when necessary (specific to the hierarchy they're in), and *also* use module relative paths by using the other Struts tags. Makes code re-use in HTML a lot more attractive :) Brice Holman, Cal wrote: Ruth>> I don't think so. They were thinking of this option. The HTML:BASE renders a tag reference relative to the page request. So if your template is in the app root then the effect is the same. I use templates that are actually in different directories so in order to ensure all relative references are to the root I use the scriplet. Not sure this is a best practice. But I do not need to worry what jsp I am coding on - all references are relative to the root. This simplifies the html and if I reorganize the site there are no links/img changes necessary. It does make IDE rendering harder since they typically do best with relative urls and no base tag.

Re: Multiple parameters
my response was about indexed properties. and the next man was just
suggesting you use strings rather than float.
fred's answer looks like it will work, in principle its along the same
lines as mine, just he's not nesting a bean in the form bean. So its
more along what you've got already.
there's been a few responses that put you on the right track.. even if
they're not the exactly what you're looking for, they'll give you some
insight..
i wouldn't worry about upsetting or hurting anyone, its just
frustrating when you see a whole list of answers and you obviously
haven't taken the time to read them. the docs are good as well.

RE: Indexed properties help!
Hello fred,
Thanks for the reply, so just for clarifiation, if I am using a
property which will be "indexed" then the getters and setters will be a
little different from the usual set and get
Ie
public String getBidAmount(int index) {
return bidAmount[index];
}
And
public void setBidAmount(int index, String val) {
bidAmount[index] = val;
}
And have to implement the bidAmoutn as an array?
Protected String[] bidAmount;
Do confirm if igot that right?
Thanks once again for ur time.

Subject: Re: Indexed properties help!
Rajat,
Here is an example of an indexed property called 'signal' (in my
application it holds complex objects, not simple strings or integers):
public OrderedSignalBean getSignal(int index) {
while( index >= this.getSignals().size() ){
this.getSignals().add(new OrderedSignalBean());
}
return (OrderedSignalBean) this.getSignals().get(index);
}
public void setSignal(int index, OrderedSignalBean signal) {
while ( index >= signals.size() ){
signals.add(new OrderedSignalBean());
}
signals.set(index, signal);
}
The 'signals' member is private and is of type 'ArrayList'. It is
created in the form's contructor and the reset method of the form :
signals = new ArrayList().
The setter and getter methods of the indexed property perform so-clled
"lazy-initialization" so you do not have to worry about the siez of the
array list.
Hope this helps.

Re: Multiple parameters
Are you sure you can use float arrays in an ActionForm.
I think ActionForm beans accept only String values. It's up to you
to do conversion from/to Float.

Re: Multiple parameters
Look man I know what its like being up against the wire, but you're
demanding that someone else bails you out the chaos. don't try and
build apps around validator you'll run into trouble.
If you took a proper look at the responses instead of wetting your

RE: Tiles And Images
Ruth>> I don't think so. They were thinking of this option. The HTML:BASE renders a tag reference relative to the page request. So if your template is in the app root then the effect is the same. I use templates that are actually in different directories so in order to ensure all relative references are to the root I use the scriplet. Not sure this is a best practice. But I do not need to worry what jsp I am coding on - all references are relative to the root. This simplifies the html and if I reorganize the site there are no links/img changes necessary. It does make IDE rendering harder since they typically do best with relative urls and no base tag.

Hi, everybody. I have my problem solved. The images
should be relative to the application root (it is
where my mistake was).
Nonetheless, if you do not mind, why it does not work
at all when I tried to put image in the style sheet:
td.bar {
background:

and I did the following in my JSP:

ActionMessage and the Validator
I read that the ActionErrors and ActionError classes will be deprecated by ActionMessage and ActionMessages.. Question 1: How will this influence the signature for a validator which today has ActionErrors as one of the parameters: (java.lang.Object, org.apache.commons.validator.ValidatorAction, org.apache.commons.validator.Field, org.apache.struts.action.ActionErrors, javax.servlet.http.HttpServletRequest, javax.servlet.ServletContext) Question 2: Since all the predefined validators use the ActionError(s) classes, I'd still have to handle the ActionError queue in my jsp-pages, even if I start writing my own validations using ActionMessage(s). Since I'd only like to handle one queue in my jsp-pages I feel we have a problem here. Did I misunderstand something?
