logic:iterate tag with html:select

[Xiuyu Zhang]

Hi all,

I am try it to do a list in the action class and pass
it to a jsp page as the html:select options.  I am
using Strut 1.0.

in the action class, I do this:


ArrayList codes = new ArrayList();
codes.add("--select one--");

request.setAttribute("CODES", codes);

in jsp, I try to do:








submit  
 


I got the following errors:

Compilation of

sorting using logic:iterate tag

[Chiyaan Schumi]

Hi *,

Is there any possibility of sorting the data elements in the form bean with 
all indexed properties in it.  I need to display this data using  
logic:iterate tag.  does struts provide any functionality similar to this.  
The data has to be displayed in html table format, by selecting any column 
for sort, the other properties need to be ordered according to the sorted 
column

my form bean:

public class IterateForm extends ActionForm {

  private int intIndexed[] ={1,2,3,4,5};

  private String strAry[] =
   { "String 0", "String 1", "String 2", "String 3", "String 4" };
   public String getStringIndexed(int index) { return (strAry[index]); }

   public String[] getStringIndexed(){
return strAry;
   }
   public void setStringIndexed(int index, String value)
   { strAry[index] = value; }
  public int getIntIndexed(int index) {
return (intIndexed[index]);
   }
public int[] getIntIndexed() {
return intIndexed;
}
public void setIntIndexed(int index, int value){
intIndexed[index] = value;
}
}
Thanks in advance
Sch.

RE: Resetting of Checkbox when using logic:iterate Tag

[Raghu.Ramakrishnan]

Hi Susan,

In my application, I do not have to reset the entire form, as I
do an update and return to the same page... The user should be able to
see the checkboxes that he set or disabled. Do you have any ideas??? One
idea given to me was to read the request parameters and then set the
checkboxes according... Plss let me know if you know of anything else...

Thanks,
Raghu

Resetting of Checkbox when using logic:iterate Tag

[Raghu.Ramakrishnan]

Hi,

I have one issue, that is I have some checkboxes within my
, and 

1) When the user clicks on the checkbox, the property corresponding to
the checkbox is set to 'on'. 
2) When the user de-clicks the checkbox(removes the check), the checkbox
is still set to 'on', how do we reset the checkbox...


My code is as follows:



 
 
P 
W
A
M
C






WorkQueueForm is the Form Bean
workQueueArrList is a property of the WorkQueue Form Bean which contains
WorkQueue Beans.


I would be obliged if you could let us know how to reset the checkbox,
when the user
Deselects the checkbox, the checkbox property in the WorkQeue Bean
should be reset to null.

Thanks,
Raghu

The Struts tags are largely in maintainence mode at this point because the
emphasis is on using standardized technologies like the JSTL.  There's
been no decision regarding the future of the Struts tags but I haven't
seen many committers interested in adding new ones or upgrading existing
tags.  There doesn't seem to be much point in maintaining proprietary tags
when the standard versions are easier to use and more powerful.

I'm glad you got it working!

Often a reasonable assumption, in the circumstances, but it turns out not so.

I got my page to work with a straight Servlet full of out.println() statements.
Then I got it working using one Servlet filling my bean and putting it in
session context and then forwarding to the other, in case that was the
problem.

And then I put in  tags to replace my  tags, which I
perhaps should have done in the first place.  I guess I assumed they'd be
as interchangeable as  and .  But 
works.  Which leads me to conclude that the problem might be in .

Am I correct in thinking that future versions of Struts may end up using JSTL
anyway?  If so, then I guess I'll keep to this approach.  Someone else can
debug  if they want to.

  hi,
  this happens only when struts is unable to load the resources from 
  the bundle. make sure u have everything in place and restart web 
  application or server.
  also u may want to try getting that prompt.username from the bundle 
  using 
  in ur jsp to actually check if struts or validator is the

If both JSTL and Struts are failing, it's probably your code that's
broken.

Okay, I got JSTL 1.0 working on my machine(after giving up on 1.1, which is
apparently too bleeding-edge).  Replacing logic:iterate with c:forEach is
straightforward.

And I still get the same problem.  Oh, the exception might come up on a different
line of my compiled JSP, but the same thing is happening.

Does this mean that it's no longer a Struts problem?  Should I be asking these
questions on a JSTL forum?

I suggest you use the JSTL's  tag instead of the Struts iterate
tag.  I have dynamic query pages that use forEach and display n number of
fields with no problem.  As an added bonus you'll get improved page
rendering time because containers can optimize the performance of JSTL
tags.

logic:iterate tag fails on large dataset, succeeds on smallone?

[Aaron Humphrey]

I am trying to do a very simple data-display web application using Struts, with MySQL 
on the
back end.

Basically, I take a ResultSet and its ResultSetMetaData and put it into some beans.  I 
have a
TableDataView object which contains a FieldList and a RecordCollection.  FieldList has 
a property
called fields which returns a List.  RecordCollection implements Collection, and 
containts an
ArrayList of Record objects; Record returns an array of the field value objects as the 
property
fieldValues.

My JSP page(showtable.jsp)looks like:


















If I run this on a small table, with 10 fields and 11 records, it works fine.  If I 
run it on a
large table, with 28 fields and 307 records, then I get:

javax.servlet.ServletException: cannot find bean fvalues in any scope
at org.apache.jasper.runtime.PageContextImpl.handlePageException(PageCon
textImpl.java:533)
at org.apache.jsp.showtable_jsp._jspService(showtable_jsp.java:192)
at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:137)
...[deletia...I can't imagine that any of it has anything to do with my error]
at java.lang.Thread.run(Thread.java:536)

I can eliminate this problem if I reduce the number of fields in the table to 9 or 10,
but I can't see why this should be a problem, and certainly not why my looping bean
should suddenly become unavailable.  My unit tests seem to be telling me that my
Record bean should be properly returning a list of 28 field values.  I don't know at
what point things are breaking down.  I'm not experienced with JSP tag programming,
so I haven't been able to learn much from IterateTag.java, or the compiled version
of showtable.jsp.  Any pointers on my problem would be much appreciated.

RE: Help- logic:iterate tag

[Kamholz, Keith (corp-staff) USX]

As far as your question about rebuilding the table, I'm not sure exactly
what you're asking.  These sorts of things are generally done automatically.

I can answer your other question though.  The 'type' attribute of the
logic:iterate tag specifies the name of the class that is stored in your
collection that you are iterating through.  For example, if you just have an
ArrayList stored in the request with the attribute "someList", and it stores
strings that you want to iterate through, you would use:


(Do something with 'thisElement')


Does that help more?

>>> [EMAIL PROTECTED] 06/09/03 01:22PM >>>
This will definitely help me , but the reason for asking this question
..

In my application my requirement is to have multiple HTML elements with
the same name.

eg:






  
   
   MH 
   MSA 
   NATIONAL 
 




But the above table can be 1 row or many rows (dynamic). Once the user
submits the page, and say there is some validation error, I want to
rebuild the table with the values from the action form.



Hope i am clear, if not I will further info.

Well, I'm not sure exactly what you want to know, but here's an example
of
how I used it in an application I'm currently working on:























"groups" is an ArrayList that I put in the request from the preceding
action.  it stores variables of type AnsmItem.  "ansm" is the local bean
name that you use within the iterate tag to access the current element
of
the collection.

Let me know if you have any questions about it, or if you want to know
anything else.

Hi

I am trying to understand the logic:iterate tag. I have gone thru the
docs
but could figure out some of the attributes of this tag.

My confusion is following attributes

1. property="" 

so should this have a get and set methods in the ActionForm

2. Collection - when will this be used

3. indexID - when should this be used

Can some body throw some insight on these tags or some examples of
usage.

Thanks

Also could u tell me as what u defined ur action form (eg: ArrayList
storing type AnsmItem, and 
what is type used for  type="com.moog.us.app.ans.data.AnsmItem">


>>> [EMAIL PROTECTED] 06/09/03 01:22PM >>>
This will definitely help me , but the reason for asking this question
..

In my application my requirement is to have multiple HTML elements with
the same name.

eg:






  
   
   MH 
   MSA 
   NATIONAL 
 




But the above table can be 1 row or many rows (dynamic). Once the user
submits the page, and say there is some validation error, I want to
rebuild the table with the values from the action form.



Hope i am clear, if not I will further info.

Well, I'm not sure exactly what you want to know, but here's an example
of
how I used it in an application I'm currently working on:























"groups" is an ArrayList that I put in the request from the preceding
action.  it stores variables of type AnsmItem.  "ansm" is the local bean
name that you use within the iterate tag to access the current element
of
the collection.

Let me know if you have any questions about it, or if you want to know
anything else.

Hi

I am trying to understand the logic:iterate tag. I have gone thru the
docs
but could figure out some of the attributes of this tag.

My confusion is following attributes

1. property="" 

so should this have a get and set methods in the ActionForm

2. Collection - when will this be used

3. indexID - when should this be used

Can some body throw some insight on these tags or some examples of
usage.

Thanks

Re: Excluding values inside a logic:iterate tag or an html:optionstag

[Ionel Gardais]

you mean to add the  or  tags inside the 
 tag ?
I guess it should work ok inside the logic:iterate tag because you know 
the name of the element at each iteration but how to do the same inside 
an html:options tag ?

I need this because I have a list of person which I want to be displayed 
in a listbox.
I want all the persons to be displayed except the user who ask this 
page. (all people except the one who ask)

thanks,
ionel

Yes it is.  Use the logic:equal and logic:notEqual tags to do this.
Let me know if you need more info.

RE: logic:iterate tag revisited

[Steve Vanspall]

Yeah that's col, I figured I would have to do that. that's the way I
originally was going to do it,

This then leads me to my next question, which was in the p.s. of my previous
post,

how does struts create a formfile for upload form the path entered by the
user.

My problem is, there could be any number of image files needing uploading,
depending on the strutcture of the template they are going into.

Hence, I can't just have a fixed number of FormFile fields in my form.

So when the user submits the file details, I want to be able to upload that
file to the server, then process it from there.

How do I do that.

There isn't much info about uploading a dynamic number of files to the serve
using struts.

Steve

Yep struts cannot simply act as you wanna do.

Before you can update your files path or everything else
you will need to tell an action :

"Hey retrieve all the kinds of datas on a whole collection
I will made some change on it"

First you got an view page who juste iterate your collection.
and have a tag just as you say to will store some variables
in your request.

But one trouble I see is you are not in a windows like program,
where you can just made some appropriate change and then
pass it to whatever you want.

If you wanna do your job, before you can send to an appropriate
action, you will need to hit it by a client side programming.

RE: logic:iterate tag revisited

[Steve Vanspall]

ok this is the full story

The value come from the form, the IMGTemplateFields object are in an
ArrayList chich is stored in the 'imageFieldsList' field of my
RenderHTMLForm

I want to have struts iterate through that list. For wach occurence of an
IMGTemplateBean I want to make a tag that will allow the user to enter the
path of a file for upload.

this will go into the 'file' field of the corresponding IMGTemplateBean.

Now my problem is, when I submit the form, using the code mentioned in my
previous message, it does not update the IMGTemplateBeans that the 'file'
fields relate to.

Not sure if I am trying to do something that struts can't do, or if I am
just doing it wrong

Regards

Steve

P.S. Alternatively how to I create a FormFile, with inputstream etc. from a
string giving me the path of a file on the clients machine.

I can't understand why you need to re-iterate .

Do you need to do some update on a view page ?

If yes you will need to have an action defined for
that, then you will be redirect on an another page
or update your change on a session scope (for
example)

RE: logic:iterate tag revisited

[Steve Vanspall]

Ok making some headway here,

I have my logic:iterate tag working, but it doesn't do what I want it to

this is my code

 
  



  
  
cnt++;

  

now I want this to populate the original field it got the value from, when I
submit the form.

I can see why this won't do it, but can't work out if struts has a way of
doing it for me

Is there a way to get struts to iterate through a list, and then re iterate
through thelist and make the necessary changes, by populating the
IMGTemplateBean with the apporopriate formFile information

Regards

Steve

are you sure it's not saying "imgFile" is not any scope??? If you look
you named one of them imgFile and the other imfFile but I don't see
where you ever declared the id imgFile ? Is imgFile declared somewhere
else?

Also, are you positive your list has IMGTemplateBeans in it? If you
remove all the  stuff and just print out "test" in there do
you get a bunch of "test"s printed out?

Are you also positive that your imageFieldsList is being populated with
the type "com.crm.util.TemplateBeans.IMGTemplateBean" You sure nothing
is spelled wrong there..etc. ?

I know a lot of this is probably obvious but it's always the obvious
that gets me:) A mistyped letter or something.

logic:iterate tag revisited

[Steve Vanspall]

Hi there

Here's my problem, I have modelled my iterate tag on a working example I was
given by a colleague.

this is my jsp code


  


  
  nameArray[cnt] = '<%=TemplateBeans.IMG_TMPLT%>:';
cnt++;




when I run it I get

javax.servlet.jsp.JspException: Cannot find bean imfFile in any scope

having debugged, when struts puts the bea into pageContext, the id it tries
to pass is set to null.

Looking at the list of variables set at the time, there are two variables
named id one set to null and one set to 'imgFile'.

I figure this is where the problem lies,

Is there something wrong withmy coding?

Any help would be appreciated

Steve

You *can* use .  Be sure to look at the docs at

No surprise here.  The "logic:iterate" tag doesn't create beans, it just references 
them.  The error message says it can't find a bean named "menge" because you never 
created it.  You either have to use "jsp:useBean" or have the bean put into the 
request scope in the action that forwards to this jsp.

RE: Using anchors with logic:iterate tag

[Galbreath, Mark]

Hmmm...interesting problem

I assume by "that part of the list," you mean when a user clicks on "C," the
first "C" word in the list is the target.

First, just in case:
http://developer.netscape.com/docs/manuals/htmlguid/tags7.htm#1227754

Second,
Using the HTML anchor tag (as defined above) you would have to program some
logic in the body of the  like:

<%
String word = "";
String letter_1 = "";
String letter_2 = "";
%>
;
letter_2 = word.substring( 0,1);

if( !letter_2.equalsIgnoreCase( letter_1) {
out.println( "" + word +
"");
letter_1 = letter_2;
} else {
out.println( word);
}
  %>


Not sure if this will work, but it seems reasonable.  Then, in your menu,
hyperlink the letters to the named anchors.

RE: Search example of complex tables with Nested tag or Logic:iterate tag

[Heligon Sandra]

I am really surprised that nobody made the model of which I speak but it is
perhaps that the nesteds tag do not correspond to the good solution. 

I would like to display a list like:

Id  NameOn/Off  
17  Paris   x
18  Rennes  
24  Londres x

If you click on the id 17 a new window is displayed with details about the
service.
The column On/off is composed of check-box and allow to factorise call to
the server
and reduce request number.

Perhaps that somebody made this type of table with the tag logic:iterate.
This mailing list offers a considerable saving of time for the developments 
I really hope that somebody could help me.

Re: CachedRowset with logic:iterate tag

[aps olute]

Ok from what I gather from the responses, it is not
necessary to use Struts Tags to iterate the contents
of the CachedRowSet.  However I would still like how
to do this. I've looked at webPIM, and were not able
to download as there are no jar files or zip files
package I saw at sourceforge.net, am not about to
pick bits and pieces and spend so much time putting it
together, if a better download site is provided i'd
apprecite it.
Am still not clear if it requires a Collection type
to do any of these iterations, not just logic, but in
html: tags too and what have you.

Re: CachedRowset with logic:iterate tag

[Chad Johnson]

You could use the "forEach" tag from JSTL
(http://jakarta.apache.org/taglibs/doc/standard-doc/intro.html).  "forEach"
can iterate over ResultSet's (and RowSet's via inheritance) with the
assistance from the helper class: javax.servlet.jsp.jstl.sql.ResultSupport .
ResultSupport can convert ResultSet's to the JSTL friendly Result class.

Hi,
When first using struts, I first tried to use a CachedRowSet object as well.
However, based on other people's recommendations, I just went with a simple
Vector of Beans, one representing each row in the ResultSet.  It is true
this is more overhead, but no one has extended the CachedRowSet to have an
iterator which is what is necessary.

It is not necessary to use struts tags; you can use scriplets.  But it is so
nice to just use the struts tags.  You can achieve almost all of the same
functionality and it looks more like an html page.

CachedRowset with logic:iterate tag

[aps olute]

How to iterate over a CachedRowSet using
 tags? I have filled the CachedRowset
with a select
statement and am able to iterate using the
crs.getString(1) or the crs.getString(colname)
methods,
but no am ready to use Struts tags but dont know how.
Do I need to convert it a Collection type? but that
will eat up more memory as two copies CRS and the
Collection with same contents?
Is it necessary to use the Struts tags to work with 
the rest of the Struts features?


<%@ page language="java" %>
<%@ page contentType="text/html" %>
<%@ page
import="sun.jdbc.rowset.CachedRowSet,javax.naming.InitialContext"%>

<% InitialContext ctx = new InitialContext();
  javax.sql.DataSource ds =  
(javax.sql.DataSource)ctx.lookup("java:/DefaultDS");
  java.sql.Connection con = ds.getConnection();
  Contacts.setCommand("SELECT name,
owner,species,sex,birth,death from pet");
  Contacts.execute(con);
  Contacts.first(); %> 


 

  


But nothing is ever printed. if i take out the
logic:present and logic:iterate and replaced with a
while (Contacts.next()  Contacts.getString(1)  at
least
i gets some output.

Display nested information(xml tree) using logic:iterate tag

[BlaineNewsletters\(@yahoo\)]

I want to parse a xml document using Jdom and then 
display the resulting tree . Below I have a sample XML, the code in the jsp page, as well as what is outputted. The nested loop 
is not working correctly. It's nesting over the parent  tag 
and displaying all  tags. Any suggestions on the nested loops would 
be great. I've actually got more nested elements under the  tags, 
but left them out for now. 
Also, the JSP isn't very clean. Any suggestions on 
cleaning it up? 



Example XML 
:--
  
Code in jsp 
page:--
 
<% test.TestConfigBean testbean = new 
test.TestConfigBean();
  java.util.List testfamilylist = 
testbean.getTestFamily(testbean.getTestIndexElement());  
pageContext.setAttribute("j_tflist",testfamilylist, 
PageContext.PAGE_SCOPE);
  %>
<%  java.util.Iterator i_tf = 
testfamilylist.iterator();  while (i_tf.hasNext()) 
{        org.jdom.Element _testType =

ttype = testbean.getTestArgs (_testType);    
    pageContext.setAttribute("j_ttlist",ttype,

RE: Another question about the logic:iterate tag

[Melissa]

Yes - yes, and again, yes. Thanks, Ted.

To further expound (in the chance that it might help someone else), when one
needs to iterate through the key/value pairs of a hashmap, instantiate the
object as type Map:

Map aMap = new HasMap();

and place it in the request.  When you need to retrieve the elements, you
can save time by using the struts logic:iterate tag as follows:





This works b/c the element that gets exposed as the iterator is actually a
Map.Entry object, which contains the key value pairs as properties (although
this utility is only available during the life of the iteration).

Very useful! It reduced my code from a natty 11 lines (see below) down to 4.

Feeling *much* better now,
Melissa

RE: Another question about the logic:iterate tag

[Melissa]

I have just tried this, but the "id" attribute is apparently required. My
guess is that this can just be an arbitrary variable... However, the bigger
issue seems to be that the iterate tag isn't really suited to the retrieval
of more than one oject (i.e. the hashmap's key/value pairs)...

here's the old code I was hoping to "convert":

<%
}
%>

Is there a way to integrate this into a Struts iterate tag, or should i just
stick with the original code?


Thanks so much for your help.

The docs say "JSP bean", but the meaning there is broad. So, yes, you
can do this:

request.setAttribute("hashmap",hashmap);

To use an actual bean, you would also specify the property



which resolves to javaBean.getHashmap()

Another question about the logic:iterate tag

[Melissa]

Hi again.  I am wondering whether the logic:iterate tag requires you to use
a bean (or bean property) as the collection to iterate over. I would
actually like to iterate over a hashmap that i placed in the request in my
action class, but I have not determined through the user docs whether this
is possible or not.

Any help would be greatly appreciated!

logic:iterate tag

[TIqbal]

Can someone explain me about property parameter in the logic:iterate tag?
I have something like below and this works fine. but I have seen in struts
example
where property parameter is alos used:

e.g. 

in this line I know 
name="user" is an object,
id="subscription" is a bean
but i can not understand
 property="subscriptions"  what is this and from where it came?

any good explanation would be highly appericated...

===


<%java.util.ArrayList list = new java.util.ArrayList();
list.add(new LabelValueBean("ONE","1"));
list.add(new LabelValueBean("TWO","2"));
list.add(new LabelValueBean("THREE","3"));
list.add(new LabelValueBean("FOUR","4"));
list.add(new LabelValueBean("FIVE","5"));

pageContext.setAttribute("list",list,PageContext.PAGE_SCOPE);

%>



 

Re: problems with the logic:iterate tag

[Craig R. McClanahan]

There was a bug in the nightly build versions through early January -- the
 tag was not exposing the variable name you specified with "id"
to the rest of the page.  This has been fixed, AFAIK.  Can you please try this
with a very recent nightly build?

For the record, where "someList" is a bean that implements Collection, the
following code should work correctly:

For 





  

  


  

  


Try 





  

  


  

  


Or, maybe just 



The real point being that the "id" property is what you want to call
the object in the given scope. So when you hand the object off from
useBean to iterate, the useBean's "id" becomes iterate's "name", and
then you pick some other "id" for the instance of each thing iterated.
(whewww.)

HTH, and let me know if it doesn't. Iterate's can be tricky at first.

RE: Newbie Question on Logic:Iterate Tag

[Jouhal, CJ]

OK.. here is my code.. I couldn't get it to work properly:

ArrayList myObj = new ArrayList();

I only add objects to the list that are instances of mySubObj

I pass myObj to the JSP page using request.setAttribute("myObj",myObj);

(I can print it out using loops)

Now this is what I had for my struts:iterate tag:

  strut test... (this should repeat)

Ted,

In this example (I'm still having problems using the iterate tag), how does
the "row" get put into a context?  Where is that bean?  According to the tag
docs, id is "The name of a page scope JSP bean that will contain the current
element of the collection on each iteration."

Basically, iterate will run through a collection object that you've
stored in one of the contexts (page, request, session, or application),
using a call like request.SetAttribute("myObj", myObj); You can then do
something like
