Re: Struts and DreamWeaver

[Antony Paul]

I face the same problem. It is more complicated if used with
jsp:include or Tiles.  So I dont give the JSP pages back to graphics
designer for editing because it wont display it properly and no Struts
html tags are understood and no html input elements displayed.  So to
edit HTML I have to go through all the steps of deploying, refreshing
and consumes time.

   And here is the advantage of JSF over Struts because it have tool
vendor support and makes the life of programmers easier by rendering
tags.

   I think that Spring is better than Struts in this repspect. I used
it only for learning only.

 I checked the archives, but only found suggestions to use something other

 My current plan is to have them use plain-old html form elements, and I'll
 automate as much as possible the task of switching them over to

 Does anyone have suggestions for coordinating page design with Struts webapp
 development?

RE: Accessing my form from an included page

[Paul McCulloch]

When you execute an action the name of the action from used is set in a
request scope attribute org.apache.struts.action.mapping.instance. It's a
fairly simple matter to get the actual actionform object if you know the
scope. For instance, all my forms are session scope so I can get the
just-used form with:

c:set scope=page var=formBean
value=${sessionScope[requestScope['org.apache.struts.action.mapping.instanc
e'].name]}/

If you don't know the scope then you'll need a bit more logic to get the
formbean.

Does that help?

Problem with logic:iterate and HashMap

[Peter Neu]

Hello all,
I have a problem with the logic:iterate tag. I need to iterate over a
HashMap which stores wrapper objects(which include the actual data).
A wrapper class has for example one attribute velocity. As far
as I know the only way to access such a HashMap is this method:
 logic:iterate id=element name=hashMap indexId=index
bean:write name=element property=key /
bean:write name=element property=value /
 /logic:iterate
Is there any way to get the velocity attribute out of the wrapper class?

Peter

Re: Inheritance of DynaActionForms

[Radu Badita]

Regarding the inheritance of DynaActionForms I've once read an very good 
and interesting article of someone who found an workaround. I don't have 
the url though, so maybe you'll get lucky with google ;-)

Hi,
I am looking for a Best practice of using the ActionForms. We are using
lot of Forms(both ActionForm and DynaActionForms) in our application. All
these Forms share some common properties and some validation logic is also
common.
Currently we are using the Inheritance in the ActionForms, to solve this
requirement(Like we have a Super ActionForm and all the other ActionForms
extend that Super ActionForm).
I would like to know, is there any possibility with the DynaActionForms. I
mean, we configure the properties of DynaActionForm in the
struts-config.xml, is there a possibility that we can say that one
DynaActionForm extends other DynaActionForm ? (with out replicating the
properties in all DynaActionForms)
As the struts-config.xml is an XML file, i guess we can imitate this by
using the XML INCLUDES( we include the super DynaActionForm properties in
the child DynaActionForms). Is there any configuration possible in
struts-config.xml ?
I wonder what are the advantages of DynaActionForms(whose properties are
configured in struts-config.xml) over ActionForms(which are Java Classes
created as JavaBeans) except the creation of extra java classes ?
Thanks,
Vijay.

RE: non-HTML attributes

Well, I'm no guru in this area, but I'd say, from some postings I've read on
the net, that some work has been done in that matter, yet nothing
official. In any case, it's not an issue for me (therefore, my not
worrying at all about that). Despite this, I'm also interested to know if
this has become a stable, robust cross-browser solution...

Another consideration is that, I believe, .htc's are IE-only.  At least, I

Has that changed?  If not, is being tied to IE an issue for you?

 Yes, Frank. Believe it or not, I know what u mean and I agree with u. ;)

 However, in this case, that would mean I'd have to rebuild views (JSP)
 which
 were tightly coupled to Struts tags/forms (time constraints at that time)
 and that would take a while.

 Indeed, for the moment, I'd decided to use plain JavaScript, but I'd
 really
 like to use the behaviours solutions (it's definitely better, more
 robust
 and powerful).

 It's sad how this tiny details can become so important at a given time.

 I remember a Servlet presentation framework I used for previous

 PAJES... it wouldn't complain about this kind of things and had some cool

 Hello everybody,

 Since TEXTAREA doesn't have a MAXLENGTH attribute (which is quite
 useful,
 by
 the way), I wanted to implement my own solution using behaviours (hfc)
 to
 alter the standard TEXTAREA element. However, I've realized that this is
 not
 compatible with Struts' tag, since TLD validation throws a validation
 exception (it detects an attribute that does not belong to the standard
 HTML
 element nor the tag specification). I'd really like to use this
 solution(no
 Validator framework or anything else). Is it possible?

 I've thought about turning off XML validation. Not sure if this is
 possible
 with Struts and, if possible, I'm not sure I'd buy that with the implied
 tradeoff.

 Ideas anybody?

Hi,

I have tried several setters in the Form class but none of them are called
when the form is terminated. How should me setter look like to the property
dropDownSelection. The getter method is:

public Map getDropDownSelection()

Here's a quick DOM-compliant function for getting the XSLT-like node

function getText(element) {
  if (element.nodeType == 1) {

  concatenation += getNodeValue(element.childNodes.item(i));
}
return concatenation;

RE: Accessing my form from an included page

[Donie Kelly]

[Donie Kelly] Hi Guys

OK, I ran through most of what your are telling me and must first thank you
all for the detailed responses.

I'm sure I need to explain my case a bit more clearly and please let me know
if what I am trying to do is easier if I take some other approach as I'm new
to struts.

1) I want to check I have a valid session so that I know the objects I have
been carrying through the session are still there. It they are not, I want
to reestablish them by redirecting back to some starting page which
initialises the session.

2) Need to put page navigation in the header.jsp page to make it easy to
navigate. I guess I will be putting stuff in the session to make so I was
going to use the form to return the breadcrumb name. Is this a good way to
do it?

That's it really.

RE: Accessing my form from an included page

[fzlists]

That's what one of my solutions was too, although I wasn't 100% sure the 
mapping instance was actually in request (I thought I remembered seeing it, but 
wasn't sure).

The argument against doing that though is that the attribute name could 
conceivably be changed down the road, breaking your code.  If your going to do 
something like this, you might be better off doing...

request.setAttribute(mapping, mapping);

...in your Actions, assuming mapping is the name of the variable passed to 
execute() for the ActionMapping object.  Yes, it's a bit of extra work in all 
the Actions, but it insulates your app from changes to the attribute name down 
the road.

I didn't notice this in the thread - but I didn't read it in depth as it was
pretty long.

I see more risk in one of my developers forgetting to add the call than in
the attribute name Struts uses changing. If that's a real concern why not
use a custom request processor to put the mapping in an attribute whose name
you define?

RE: Accessing my form from an included page

 [Donie Kelly] Hi Guys
 
 OK, I ran through most of what your are telling me and must first thank
 you
 all for the detailed responses.

You spawned an interesting thread!  The seemingly simple questions are usually 
the ones that do that though. :)

 1) I want to check I have a valid session so that I know the objects I
 have
 been carrying through the session are still there. It they are not, I want
 to reestablish them by redirecting back to some starting page which
 initialises the session.

I can tell you the way I've done this in the past... Firstly, note that the 
best way is with some plug-in to your web server (or app server) that 
externalizes security, something like Netegrity for example.  This would handle 
expiring sessions and such as you want, redirecting to some logon page 
presumably.

In the absence of that though, what I've done is to have an ActionHelpers 
class... This class contains two methods, start() and finish().  start() is 
called at the start of each Action and finish(), you guessed it, is called 
right before returning the ActionForward.

Let's ignore what finish() does because it's not applicable here... start() 
however is... The first thing it does is calls checkSession() (my own method) 
that verifies if the session is valid or not, and redirects to the logon page 
if it's not.

That takes care of one piece of the puzzle... the other is what happens if 
someone accesses a JSP directly?  All I do here is call checkSession() 
directly.  If it's invalid, the page renders a redirect.  So, all the JSP's 
have a structure along these lines:

% if (!ActionHelpers.checkSession()) { %
 HTMLHEADTITLE/TITLE
 META HTTP-EQUIV=refresh CONTENT=0;URL=http://www.mysite.com/logon.do;
 /HEADBODY/BODY/HTML
% } else { %
 ... The actual page goes here
% } %

That does the trick.  I'm in NO WAY saying this is industrial-strength 
security, but it gets the job done.  In the environment I do this in, security 
isn't an issue though, so this is fine.  Also, it wouldn't be trivial I think 
to hack this anyway since you have to get a valid session on the server at some 
point that matches what's on the client, and assuming that can only be done 
through some logon procedure, it should be not completely insecure :)
 
 2) Need to put page navigation in the header.jsp page to make it easy to
 navigate. I guess I will be putting stuff in the session to make so I was
 going to use the form to return the breadcrumb name. Is this a good way to
 do it?

I would suggest looking for a canned breadcrumb solution.  There was a recent 
thread about just that, and some existing solutions were mentioned.

If your going to build your own, you need to determine what information you 
really need to construct your nav bar.  I doesn't sound like you need access to 
the Form Bean, as I had thought you were asking originally (maybe you were, 
maybe I misunderstood... doesn't really matter I guess :) ).  Sounds like what 
you really need is the Action path for all the pages that have been visited in 
order.

I would myself be thinking of a linked list structure, stored in session, with 
each item holding the mapping path.  That should be all you need to construct a 
breakcrumb path.

But again, no sense reinventing the wheel... Solutions for this exist already.

 That's it really.

Oh, I misunderstood.  Sorry!  Off the top of my head without much

RE: Accessing my form from an included page

[Paul McCulloch]

1) You'll pretty much always have a valid session - the container will
create one for you if it isn't already there. What you need to do is
establish if an *initialised* session is there. 

One way to do this would bet to, in your initialise session action, create a
session scope attribute to say so:
request.getSession.setAttribute(ValidSession, Boolean.TRUE);

To check that you have a valid session I'd implement a Filter
(http://java.sun.com/j2ee/sdk_1.3/techdocs/api/javax/servlet/Filter.html)
which would check for the presence of the attribute. In it's absence send
the user back to the initialise action.

All of this pre-suposes that you *don't* have security requirements. If you
do then look into a security framework, such as container managed security,
which will very probably already have things in place to deal with your
scenario.

2) Don't know. Check the group archives
(http://marc.theaimsgroup.com/?l=struts-userr=1w=2) - breadcrumbs have
come up before.

A long thread??  With Jack and I involved?!?  Surely you jest... :)

We're probably the two most verbose guys around these parts!
 
 I see more risk in one of my developers forgetting to add the call than in
 the attribute name Struts uses changing. If that's a real concern why not
 use a custom request processor to put the mapping in an attribute whose
 name
 you define?

Fair point.  I didn't mean to imply it was a particular big risk by the way...  
Certainly if the Struts team did change it we're not talking about a 
monstrously difficult task to change it on our side anyway, especially if it's 
just in JSPs as we were talking about.

 That's what one of my solutions was too, although I wasn't
 100% sure the mapping instance was actually in request (I
 thought I remembered seeing it, but wasn't sure).

 The argument against doing that though is that the attribute
 name could conceivably be changed down the road, breaking
 your code.  If your going to do something like this, you
 might be better off doing...

 request.setAttribute(mapping, mapping);

 ...in your Actions, assuming mapping is the name of the
 variable passed to execute() for the ActionMapping object.
 Yes, it's a bit of extra work in all the Actions, but it
 insulates your app from changes to the attribute name down the road.

Re: Which setter do I need in the ActionForm for this example?

[Richard Yee]

Zsolt,
The selected item in a html:select input is typically a String property. It 
is separate from the collection that is used to populate a dropdown list. 
You should have a getter and setter for a string property and use that 
property as the value of the property  attribute of the html:select tag.

Re: Accessing my form from an included page

[fzlists]

 Lord, Frank --- no worries.  One of the worst things is people who
 take things too seriously and read jots and tiddles on these lists.
 Relax with me.  Sounds like therapy?  LOL  ;-)

Therapy... I could use that :)

 I did not mean that it was in the response object but accessed within
 the object building the response object, as well as other places.

Ok, gotcha :)
 
 This is the misconception, I think.  ActionForms are not for pages but
 for Actions.  A page can have a multitude of Actions and ActionForms
 in any particular tile.  ActionForms are never tile or page bound.
 Indeed, I think, the same ActionForm and Action can be found in
 various places in a single tile or page.  Right?  The ActionForm and
 Action are part of the framework and not part of the view in the MVC.
 You know this I know.  I am just thinking out loud and not really
 concentrating on the communication aspect.

I absolutely agree.  I also have to say I've only toyed with Tiles 
superficially, so any discussion that brings that in I'm a bit out of my 
element with.  I don't think that applies here though.

It is true however that for any given page, it's only going to use a single 
Form Bean, as far as Struts goes.  What I mean is, unless you yourself pass 
more beans (as I do in one app, via the request object), Struts only allows for 
a single Form Bean, per page, per request.  This is, I think the relevant point 
for this discussion, even though we now agree Donnie wasn't actually asking how 
to access the Form Bean :)  Indeed, if there could be more than one bean 
available, the question would be more difficult because now you'd also have to 
ask which bean to go after in addition to what name to use and in what scope.
 
 The bean is available without being imported.  It is in scope because
 of the framework.  Right?  Importation is just for identification.

Yes, after I wrote that I was worried the use of the word import would be 
confusing... I didn't mean to say or imply that you had to import anything... I 
was using it to refer to one JSP including another... That's something like an 
import... Bad usage of the term :)
 
 Sure you remember the good part.  We have family here for the holidays
 and people were laughing about the town pornographer of some years
 past.  His son was blind.  How ironic, we thought.  H.  Seemed
 funny then and cruel now.  You have to have been there.  My wife's
 brother was talking about how he beat up the blind kid in camp.  Turns
 out this made the blind kid happy because he felt part of the group.
 God knows I must have really been part of the group under the measure.
  LOL

If I'd have known that I could have been beating up handicapped kids for the 
holidays all through school :)  Would have been a great present for them!
 
 True, but all Donie wanted was the *name*, which is passed to the
 ActionForward in creating the ActionForward.

Yep, I WAS playing the Scottrade guy... Always trying to give more than is 
requested :)
 
 This is where we were parting ways.  Donie just said he wanted the
 name. So, that is what I have focused on.

I'm with ya :)

 Yah.  I think we've got this down alright?

For the sake of ever seeing this thread die, I agree :)

 I don't know if I am a fan of taglibs but I develop enough of them
 myself.  They are fairly easy to write once you get the hang of it and
 I build a custom suite pretty quickly.

I've written a couple myself as well.  To say I never use them wouldn't be 
accurate, but to say I think of them first in any given situation also wouldn't 
be accurate.

Then again, my environment is not one where we separate page developers from 
business class developers (although we may be moving in that direction).  In 
such an environment I suspect I would be more in favor of taglibs as I think 
that's where they really start to pull their weight, so to speak.  Absent 
that situation though, I find them more trouble than they are worth 8 times out 
of 10.
 
 I am surprised at this.  I like them for what they are worth.  Why do
 you hate them?

Well, I think my main objection is complexity.  I think they tend to add more 
than they take away.  So long as we're talking about purely presentational 
code, I don't have a problem with scriplets in JSPs, in fact I prefer being 
able to see precisely what's going on in one place without digging through some 
other class somewhere.  Obviously you have to be careful not to let application 
logic sneak in.

Taglibs are just more to configure and more dependencies.  Not a huge amount I 
admit, but I'm a simplicity bigot, I like my apps to rely on as little as 
possible, have as few pieces as possible.  I don't feel like taglibs do this, 
most of the time.

As I said though, I DO use them when I think it's warranted, but they aren't my 
first answer to a given problem, 8 times out of 10.
 
 Oh I have done that too.  I think of ActionForms more as data grabbers
 and do not take them too seriously.  Struts is great but

Re: Which setter do I need in the ActionForm for this example?

With multiple=true, I think that you need a property of type String[] 
in your ActionForm.

Zsolt,
The selected item in a html:select input is typically a String property.
It
is separate from the collection that is used to populate a dropdown list.
You should have a getter and setter for a string property and use that
property as the value of the property  attribute of the html:select tag.

If you are using Dreamweaver, and using its facilities to insert a flash 
button, just set the link to:
javascript:document.formName.submit();

If its a button you created in Flash yourself, then I'm not sure. I 
think you have to set it up to call the JS, but I don't know how.

You'll need to write a little bit of JavaScript to get that to work 
well.  Try adding 
onclick=document.forms.namedItem('yourFormName').submit()

(See

Struts tags / JSTL question

[Vinicius Caldeira Carvalho]

Hi there!
I have a collection of beans, and this collection is set to the request. 
I'd like to retreive only the first object of the collection (later on 
I'll iterate over it completely) How can I do this? My Collection is a List.
I tried c:set var=bean value=${collection.get(0)}
and also c:set var=bean value={$collection.iterator.next}

none of 'em seems to work. Any ideas?

session form bean problem

[t t]

Hi, all,
First, happy holidays to you!
I got a question. I have such action mapping:

action path=/Populate
   type=myClasses.PopulateAction
name=SearchForm
scope=request
   validate=false
   forward name=success path=/search.jsp/
   /action
-
I want to populate SearchForm with some existed values(stored in session) 
before showing search.jsp. This work is done in execute method of 
PopulateAction.
It works well when I use the mapping code shown above. But when I take out the 
line -- scope=request, that is, I want this form bean to be a session bean. 
Then the values were not set. They are  just the initial values of the form 
bean. 
It seems a new form bean object was created after execute method of 
PopulateAction. Or , execute method of PopulateAction was not executed.
Any idea anyone?
 
Thanks in advance.

Re: Struts tags / JSTL question

[Dakota Jack]

I just sent a couple of classes using a standard list iterator/handler
pattern from the core J2EE design patterns book to Uma.k on this list
that answer this with one solution.  I will send it along to you too. 
I think that when you see the code the answer to your question will
become obvious.  ListHandler allows you to access members of the list
in a very sophisticated way.  This is a very handy and simple design
pattern.

Re: Struts and DreamWeaver

[Dakota Jack]

But it is good to have the choice between JSF and Struts.  Hopefully
they don't become one as proposed in Shale so that the choice is gone.
 I don't take Dream Weaver people too seriously because I don't run in
that crowd.  I do understand that the Dream Weaver crowd, however, is
real and important and has its own needs.  I cannot imagine a large
scale commercial project on Dream Weaver and consider it a part of the
small site area of the industry, but I probably am mistaken.

Help needed - submitting dynamic text boxes to ActionForm

[krishna mohan d]

Hi,

I am struck in the middle of one web application. I am using struts 1.1 
framework.

I have a form where I have nearly 12 text boxes per row, which are generated 
dynamically.

means I have a form where I have 12 text boxes per row and I am assigning name 
dynamically.[I am using plain jsp and javascript].
The number of text boxes depends on the value fetched from database.

suppose if my database value is 10, 
my form will be having 12 [Textboxes per row] * 10[no. of rows] = 120 
textboxes. if the database value is 5, I will be having 60 textboxes.

my question is
How to write the action form.

I think it is a bad programming to write 120 properties and 240 methods [getter 
and setter].Also beacuse the textboxes changes depending on the database value, 
I think I cannot define 60 / 120 /200 properties and getter and setter methods.

How to handle this situation and submit the data entered by user to the action 
form, get them into Action class.

Any help on this is appreciated.

Thanks
Krishna.

Input type with map-backed action forms

[icon911]

I am trying to have a form built at run time. It seems that map-backed
ActionForms good fit for what I need. Hower I have a problem coming up
with a solution as to what to do when not all input types are text
fields, so this does not work

html:text property=value(foo)/

because the field has to be text, what if its checkbox?

Basically when fields are dynamic and I retrieve them using a loop,
what can I do to determine if it will be a text field or a checkbox or
so on  Is there a way to add to a map a LabelValueBean so label
would be the actual field name and the value its type, or something
like that?

Re: Struts and DreamWeaver

[Antony Paul]

I added Struts html tags to DreamWeaver using the add tag from tld
option. But it is not rendering the tags as html elements. I use
DreamWeaver  for visual display.

 Hi
 I use macro media dreamweaver and can add tag library
 and so can support struts or jstl, i explained my
 graphical designer to use these tags instead of html
 tags and it worked out well, try teaching graphical
 designer to use tags..

  there's the fun of JSTL
  tags embedded within HTML tags, which works fine
  but can't exactly be

  I checked the archives, but only found suggestions
  to use something other
  than DreamWeaver.  I don't think that's going to go
  over well.
  
  My current plan is to have them use plain-old html
  form elements, and I'll
  automate as much as possible the task of switching
  them over to
  html-el:... tags.   Not much fun, but far better
  than having to do the
  page design.
  
  Does anyone have suggestions for coordinating page
  design with Struts webapp
  development?

DB Connection Best practice

[uma.k]

Hi,
I wanted to insert a record into the database or
update a record in the database or
get a record from the database.

Where do I make my database connection? Is it in the Action class? Can I
make a single java class handle all of that for me?

If the above are wrong. Please let me know which is the best practice to do
this.

Thanks
Uma

Better practice would be delegating to a handler (application layer)  
class and let it return data in form of some bean and use that in action.
In this way you'll be isolating Controller from Business model.
