RE: logic:iterate question

I don't think you can pass parameters in JSTL, at least not yet.  But
you could, in your action, call getModelList passing the String you got
from the request, and then when you forward to the JSP, iterate over
that Collection.
I am not sure what you meant, Wendy, but, in case you meant that you cannot 
use parameters, then check out: 
http://jakarta.apache.org/struts/faqs/indexedpropers.html .

If this is helpful, I use this with a BeanMap I whipped up:

public final class BeanMap
implements Map {
  private Map map;
  private BeanMap() {
  }
  public static Map getInstance(Map map) {
BeanMap bean = new BeanMap();
bean.setMap(map);
return bean;
  }
  public void setMap(Map map) {
this.map = map;
log.info(this.map);
  }
  public void setValue(Object key, Object value) {
map.put(key,value);
  }
  public Object getValue(Object key) {
return map.get(key);
  }
  // Forwarding, composition, methods
  public void   clear()   { map.clear(); }
  public booleancontainsKey(Object key)   { return 
map.containsKey(key);}
  public booleancontainsValue(Object value)   { return 
map.containsValue(value); }
  public SetentrySet(){ return map.entrySet(); }
  public booleanequals(Object object) { return 
map.equals(object); }
  public Object get(Object key)   { return map.get(key); }
  public inthashCode(){ return map.hashCode(); }
  public booleanisEmpty() { return map.isEmpty(); }
  public SetkeySet()  { return map.keySet(); }
  public Object put(Object key, Object value) { return 
map.put(key,value); }
  public void   putAll(Map map)   { map.putAll(map); }
  public Object remove(Object key){ return map.remove(key); }
  public intsize(){ return map.size(); }
  public Collection values()  { return map.values(); }
  public String toString(){ return map.toString(); }
}///;-)

Forgot the obligatory, "but you should really do this in an action". There's no
reason to clog your JSP with this kind of stuff. Grab the collection in an
action, set it as a request attribute, forward to the JSP, and...

You should be able to use BeanUtils' mapped property access for this, right?





Which should give you a bean called "modelList" that holds your collection. This
assumes there's a bean called "bean" whose class implements the getModelList method.

I don't think you can pass parameters in JSTL, at least not yet.  But
you could, in your action, call getModelList passing the String you got
from the request, and then when you forward to the JSP, iterate over
that Collection.

If getModelList returned a Map, or you made a getAllModelLists method
that returns a Map, you might have this:




That depends on how big they are, and whether they change for each user.
If you models are fixed and change infrequently, you might be able to
put a big Map in Application scope and use it across the entire webapp.

Out of curiosity, what class is getModelList from?

Hi,

Thank you for your answer.I would like to change the code shown below,

this:

requestString is a parameter of the http request..

JSTL and/or Struts-EL can probably help, but I'm not quite sure what

However, i have no idea what to fill in in the dots (should be something like

any hints on how to do this?

The following link should help:

http://www.mail-archive.com/[EMAIL PROTECTED]/msg71256.html

however it talks about using el, but this is not
necessary.

I have got the nested tags to work properly.  The
logic tag should work, but I think I was doing
something slightly wrong when I tried.

Remember to have

getMap(String key)

and 

setMap(String key, Object value)

in your form.  The online help has more on this.

Re: logic:iterate question

[Garth Patil]

my previous question regarding use of logic:iterate with a HashMap can be 
cleared up by using the 'name' attribute rather than the 'collection' 
attribute in the tag.
now that i figured that out, i'm having some trouble nesting an iterate. now 
that i have the example below actually able to render, the nested 
logic:iterate only generates one result (although there are many in the 
Collection) before moving on to the next result in the outer iterator. any 
ideas how to fix this?
thanks /gp

Dumb question:  Is the object reference 'myObj' pointing at anything before
set it to the name 'myObj'?  That sounds confusing -- too many myObjs

You'll have to use indexed property getters.  I believe you'll also have to put vTwo 
into your form bean so you can take advantage of the indexed property getter.

Like so:



,
 
:  


I used single quotes around the attributes here because of the double quotes within 
the JSP expression, b.t.w.


Note that this would be a lot cleaner if you used a Tuple object (named whatever you 
like) that contained (number,letter) fields and use a single Vector of these objects:

:

Just read the API description for "".  Your answer is one of
the attributes of "".  I'm leaving out the actual attribute
name to make sure you read it, because it is very useful to go through it.

I have not used the indexId property before myself, but I have experienced with other 
properties/tags that names you define in the tag itself is not available from 
scriptlets. So the snippet <%= index%> will return an empty string or fail.

Subject: logic:iterate question


Hello all,

I've got a question about the logic:iterate tag.  I'm trying to
reference a bean which returns a String[] but I only want one of the
values in the array.  The indexID is working but it isn't getting passed
to the bean:write tag corretly.  It throws a 

java.lang.IllegalArgumentException: Invalid indexed property
'attributeNames[]'

If I passed the bean a hardcoded index value, it works.  I can also
print out the value of the index.  I think it may be some kind of timing
issue in struts and maybe it can't be done.  Any Ideas?







 


Thanks,
Graham

Correct your bean:write tag so attribute property becomes full scriplet
syntax coded :

property='<%= \"mapController.dataConnection.attributeNames[\"+ index +
\"]\"%>'

I can do that I suppose, but not sure whether old netscape users like
multiple forms.
Other problem is that if you define forms within a table the table row will
become larger, but thx for that solution

It should be something like this



 instead of the static 

checks this document http://jakarta.apache.org/struts/struts-html.html for
 reference doc.

Hi ,

>From what I understand you want to create links for each headline and pass
the head line as a parameter.
So inside the logic:iterate tag U should put :

 
   <%info.put("HeadLineID", "X"); %>

   Headline 


U can replace the one line of code with 

It worked for me.

If you mean, can you wrap a long column into two or more columns, like a
newspaper article, then there is no html way to do this. You would need to do in
manually somehow.

Hi all,

I am using the iterate tag to iterate over a collection of items stored in
the FormBean. And all work fine (so far :) ). My question is: A I have a
large number of items in the collection is it possible arrange them in
columns?? Here is a code snippet:

 
  

  
  
  
  

  


This prints everything in one long column. Is there a html thing I can use??
