Re: AAAARGH! SOMEONE! How do I set the default selection when I'musing html:options?

[Eddie Bush]

Go look at the ValidatorPlugin source :-)  Here is a brief overview:

Each plugin gets a reference to:
- an ActionServlet instance
- an ApplicationConfig instance (for the current "module")

You can use the ActionServlet instance to get at the application 
(servlet-context) scope and then set an attribute.  It'd go something 
like this:

servlet.getServletContext().setAttribute("myAttribute", myVar);

That will result in you having a variable out there in application scope 
named "myAttribute" which is a reference to "myVar".

Note that you're not constrained to using a plugin.  A context listener 
would also get a reference to the context (the application-scope), so 
you could easily adopt this approach too -- especially if there's 
nothing special you need from Struts in order to configure whatever 
you're poking out there :-).  My modules need to know which sub-app they 
are associated with, so I can use that information later ;-) so I have 
opted for the plugin route.  I can get the prefix from the 
ApplicationConfig (config.getPrefix()), and that's enough information 
for me to tell "where I am".

Eddie,

I agree with your approach.  How can I place the beans into application scope?  
Forgive me if these seems ignorant.

Here's what I do:

- Plugin uses digester to load config into bean instances.
- Place the overall container into application scope under a known key.

I don't particularly care of the Struts approach of "declare a constant 
in some distant package for this key", as, at best, it causes the 
introduction of a run-time expression (at least that's the way I've 
found to do it - someone please tell me if there is a better way).  I 
just defined a key under which my config could be found -- and I stick 
to it everywhere.  I wish struts would adopt this approach ...

The top-level object in my graph is a ModuleManager instance.  Once that 
is initialized, I poke it out into application scope under the key of 
"moduleManager".

I suppose Struts uses the keys it does so that it doesn't trample on 
folks names-space.  Personally, I'd give up what insignificant amount of 
namespace Struts would require -- just to have the keys more easily 
accessible.  (hrm ... application config in app scope under "appCfg" or 
"strutsAppCfg" or the like .. same deal on mappings ... resources ... hrm)

No, that's not true.  You can set it to be loaded on startup -- just 
like Struts' own ActionServlet is done.

Jan,

Definitely clear; however, using an Init servlet requires someone to access that 
servlet each time I restart the server, correct?  When I really think about it, that's 
not a big deal, but it's something I might forget :).

How to by using an Init Servlet.

Some examples, since explaining would take too long :

Java startup servlet
---cut---
package org.init.whatever;

import javax.servlet.*;
import javax.servlet.http.*;

public class InitServlet extends HttpServlet {

public void init(ServletConfig config) throws ServletException {
super.init(config);
//DO WHATEVER YOU NEED TO DO HERE
//config.getServletContext().setAttribute("states","some object with 
states in it");
}

public void destroy() {

}

/** Processes requests for both HTTP GET and 
POST methods.
* @param request servlet request
* @param response servlet response
*/
protected void processRequest(HttpServletRequest request, 
HttpServletResponse response)
throws ServletException, java.io.IOException {
//do nothing
}

/** Handles the HTTP GET method.

*/
protected void doGet(HttpServletRequest request, HttpServletResponse 
response)
throws ServletException, java.io.IOException {
processRequest(request, response);
}

/** Handles the HTTP POST method.

*/
protected void doPost(HttpServletRequest request, HttpServletResponse 
response)
throws ServletException, java.io.IOException {
processRequest(request, response);
}

/** Returns a short description of the servlet.
*/
public String getServletInfo() {
return "Init ME";
}

}
cut 
again-
in you web.xml:
-cut cut 

Init Servlet
Init Servlet
Servlet to initialize whatever
org.init.whatever.InitServlet

param1
WEB-INF/maybe.some.file.if.you.need.such.a.thing.properties

Is it clearer or as mud ?

Both are much easier than I thought.  Thanks for the help.  One question remains: if I 
were to have a ConfigurationPlugIn, for example, how would I get that information to 
each servlet.  Should I create static method within the ConfigurationPlugIn class that 
returns an object with all of the config values?

Yeah, actually this might be your best approach.  Mine would depend on 
Struts.  This approach would be totally independent of Struts.  If 
you're (wasn't it spec 2.3 that brought us these listeners?) on an older 
spec, using the plugin may well be the way to go though.

javax.servlet.ServletContextListener @since Servlet2.2 spec acts a
bootstrap.
Prior to Servlet2.2 spec, try a bootstrap  servlet.

A quick scan of the mailing list archives and .
http://www.mail-archive.com/struts-user@jakarta.apache.org/msg38242.html

Re: AAAARGH! SOMEONE! How do I set the default selection when I'musing html:options?

[Eddie Bush]

Michael,

I'm currently building some functionality on top of Struts for a 
project.  The way I found to do this the easiest was to keep my config 
in an XML file and use the commons digester in a Plugin.  Plugin writing 
is very straight-forward, and there are a couple of standard examples 
(TilesPlugin/ValidatorPlugin) out there for you to look at.  Personally, 
when I started in, I looked at the ValidatorPlugin.  It's much shorter 
and covered everything I cared about.

Note:  If you needed to get persistent stuff out of a database, you 
could do your DB-access here to load your beans.

This is probably one of the stupidest questions, but I don't know how to do something 
once during application startup.

For instance, if I wanted a bean to hold a list of states, how would I create that 
once during startup?

One more advice to make your life easier: Why bother getting the states 
from the database for every form ( or even the same form ) when it's 
accessed ? I think the better way is to load the states when the app 
starts up and store it in the application bean in format that you can 
get the list very easy way, by getting it from the application bean on 
the form, like this :








both "statesarraykeys" and "statesarrayvalues" in the application bean 
are "ArrayList"(s).

Let's face it, how often a list of US states changes ? Once in 500 years 
? :)

Aboslutely - must have been brain-dead for not thinking of that (especially

One more advice to make your life easier: Why bother getting the states 
from the database for every form ( or even the same form ) when it's 
accessed ? I think the better way is to load the states when the app 
starts up and store it in the application bean in format that you can 
get the list very easy way, by getting it from the application bean on 
the form, like this :








both "statesarraykeys" and "statesarrayvalues" in the application bean 
are "ArrayList"(s).

Let's face it, how often a list of US states changes ? Once in 500 years 
? :)

RE: AAAARGH! SOMEONE! How do I set the default selection when I'm using html:options?

[Galbreath, Mark]

In your Action class, call a data access object to get a ResultSet from your
database containing all the states and pass them as a List.

Action class:
myDAO dao = new myDAO();
dao.getStates();


DAO:
public List getStates() throws SQLException {
  List states = new ArrayList();

  while( rs.next()) {
states.add( rs.getString( "[name of db column containing states]");
  }
  return states;
}

Action class:
MyActionForm actionForm = (MyActionForm) form;
form.setStates( states);

ActionForm class:
private List states = null;
public void setStates( List states){
  this.states = states;
}
public List getStates(){
  return states;
}

JSP:

  Select A State

RE: AAAARGH! SOMEONE! How do I set the default selection when I'm using html:options?

[Sri Sankaran]

The default value of a  is driven by the value of its property attribute. 
 So, for example, if you have


  Blood
  Leaves
  Sky


and if the 'userChoice' property of the form bean is set to "green", then the default 
selection will show "Leaves".

Please see html-select.jsp that is part of the struts-exercise-taglib war that ships 
with Struts.

I have a list of countries in my JSP:








And then in my ValidatorForm class's reset() method I have:


ArrayList countries = // list of countries from LDAP
String shippingCountry = // users country from LDAP


When the page displays the  list has all of our countries, with the

RE: How do I set the default selection when I'm using html:options?

[wbchmura]

So...

Is that a problem?  I almost think that with something like states you 
would want it to appear as the default and then also in the normal order 
of states...

Tried it.
Problem with that is you now get 2 options that are the same.
ie:

Re: How do I set the default selection when I'm using html:options?

[Michael Lee]

Tried it.
Problem with that is you now get 2 options that are the same.
ie:
GA
AK
AL

GA

RE: How do I set the default selection when I'm using html:options?

[Hoang, Hai]

You need to populate the value of the property of the dropdown before the
jsp is render...the best way to do this is in the action class.

For example, you have getter and setter for State in the form bean...now you
need to setState("TX") in the action class if you want to have Texas as a
default state.

You can add in an  tag above the  tag that 
will be the default.

That's why I sent you a link to the javadocs in my response, and how I knew the 
attribute values should be "value" and  "key".  ;)  I figured you being a smart dude, 
you'd rather figure it out yourself, which you did in about 5 mins.

Re: HELP! html:options with a hashmap

[Michael Lee]

I agree but it's not in a form, it's pulled from a helper class.
I did a little research since you told me about the entrySet() in HashMap.
Since there are no get/set methods in HashMap/Set I thought that "key" and
"value" were just reserved words in struts. This kind of bugged me since it
seemed to deviate from the whole struts/jsp introspection model. I figured I
was missing something and so I looked into entrySet() and this acutally uses
a HashMap internal class called Map.Entry. The javadocs for this are under
java.util.Map.Entry. In the javadocs show Map.Entry has a getKey and
getValue method. I let out a big 'ah' when I saw that. It all makes
sense now. That's why it works and why you can just use a HashMap as long as
you use "key" and "value" (the getKey getValue internal to HashMap). I never
would have found this without that clue (entrySet()). I've included my
updated code below...

 // This gets a HashMap and puts it in a variable called alluserRoles
<%
  pageContext.setAttribute("allUserRoles",
Lookup.getData(Constant.USER.USER_ROLES));
%>
.

  


If you use lots of static data, like dereferencing lists in a database, then
this is very handy.

Mike

Cool.  Glad it works.  You could probably do away with the scriplet by
adding another property getter in your action form though, call it
getAllUserRolesKeysAsCollection, or some such title, and just return
myHashMap.entrySet().  To be honest, I've never used a Hashmap like this in

RE: HELP! html:options with a hashmap

[Joe Barefoot]

Guess I should've mentioned:

Doing it the way below, you'd still need this tag so's the options tag can 'see' the 
collection:




IMHO, the attributes for the options tag was not very well thought out, particularly 
because it does not adhere to the standard name/property way of specifying something 
from your form bean, the way nearly every other tag does.

Joe

Cool.  Glad it works.  You could probably do away with the scriplet by adding another 
property getter in your action form though, call it getAllUserRolesKeysAsCollection, 
or some such title, and just return myHashMap.entrySet().  To be honest, I've never 
used a Hashmap like this in Struts.  I've always used an ArrayList for the Collection, 
populated with KeyValuePair objects (with key/value getters).  Good to know it can be

Re: HELP! html:options with a hashmap

[Michael Lee]

Wow! This worked like a champ! What I was doing was actually not what you
were saying. What I was doing was much more complicated. This is MUCH
cleaner.

The thing I didn't know about we're the "key" and "value" names. I found the
"value" one but didn't understand exactly how to use it. I found the only
pertinent example on some spanish web site. I tried to figure out what they
were doing but to no avail. (Hey Marc, how's that for well documented?)

Anyway, here's the code for all to enjoy;
...
***This section gets the HashMap with the Lookup.getData() method
then calls .entrySet()*
<%
pageContext.setAttribute("allUserRolesKeys",
Lookup.getData(Constant.USER.USER_ROLES).entrySet());
%>


  


Thanks again Joe,
Mike

You don't see an example because html:options expects a *Collection*, not a
Map.  I have no idea if the tag works with a Map, but it probably doesn't
because it expects a Collection object.  If you want to use a Map
implementation (like HashMap), then your property getter should return
myHashMap.entrySet() and you should set these attributes in the
: property="value" labelProperty="key".  Something like
that.

http://java.sun.com/j2se/1.3/docs/api/index.html


Struts javadocs are quite verbose:

http://jakarta.apache.org/struts/doc-1.0.2/api/index.html

Click on any of the taglib packages in the top left frame, then the package
name in the bottom left frame, then the "Description" link that comes up in
the right frame.  Gets you descriptions of any tag.  You can reach these
throught the Struts site as well.

Re: HELP! html:options with a hashmap

[Michael Lee]

Hmm, that's the way I'm trying/having to do it now, it just seems logical
that it would use the keys as the html option value and the map values as
labels by default. Oh well.
Ok, kinda depressing (We have to do this A LOT). Thanks for your help Joe.

HELP! html:options with a hashmap

[Michael Lee]

I posted this before but haven't heard anything. Thought I would put up the error 
message too. What name do I put for name? The examples don't use a hashmap (seems 
logical for 'options'). When I put name it does the name and value. I want it to put 
the name under name and value under value, not both in the drop down.

I want to populate an  with data from a Map (HashMap). I have

...
<% pageContext.setAttribute("allUserRoles", Lookup.getData(Constant.USER.USER_ROLES)); 
%>
...


  


I don't see an example in the struts-exercise-taglib.war under html:select

Re: Help with html:options

[Matt Veitas]

Change the attribute "name"  to "collection" and it should work.

This tag operates in one of two major modes, depending on whether or not 
the |collection| attribute is specified. If the |collection| attribute 
is included, the following rules apply:

* The *collection* attribute is interpreted as the name of a JSP
  bean, in some scope, that itself represents a collection of
  individual beans, one per option value to be rendered.
* The *property* attribute is interpreted as the name of a property
  of the individual beans included in the collection, and is used to
  retrieve the value that will be returned to the server if this
  option is selected.
* The *labelProperty* attribute is interpreted as the name of a
  property of the individual beans included in the collection, and
  is used to retrieve the label that will be displayed to the user
  for this option. If the |labelProperty| attribute is not
  specified, the property named by the |property| attribute will be
  used to select both the value returned to the server and the label
  displayed to the user for this option.

Help with html:options

[Kamal . K . Kang]

hi all,

I am getting the following exception in html:options tag.

[ServletException in:/jsp/EditServerBody.jsp] No getter method available 
for property value for bean under name nngList' 

This is how I am using it



Where nngList is of type Vector and it contains elements of type 
OptionValue which has getValue() and getLabel().

Anything else I am missing.

html:options

[tsawyer]

Hi,

We're trying to use the html:options tag (struts 1.0.2) to render a drop list 
containing the values from a String Tokenizer, which is tokenizing a comma delimited 
string.  We just want a drop list that contains each of the values in the list, with 
the value and description identical.

The behaviour we are seeing is that we are getting half the number of options, because 
the code is sticking the first value from the list as the value, then the second as 
the description, then the third as the second value, and the forth as the second 
description. 

This would appear to be bourne out by this code from the tag itself:

  // Otherwise, use the separate iterators mode to render options
else {

  // Construct iterators for the values and labels collections
  Iterator valuesIterator = getIterator(name, property);
  Iterator labelsIterator = null;
  if ((labelName == null) && (labelProperty == null))
  labelsIterator = getIterator(name, property); // Same coll.
  else
  labelsIterator = getIterator(labelName, labelProperty);

  // Render the options tags for each element of the values coll.
  while (valuesIterator.hasNext()) {
  String value = valuesIterator.next().toString();
  String label = value;
  if (labelsIterator.hasNext())
  label = labelsIterator.next().toString();
  addOption(sb, value, label,
selectTag.isMatched(value));
  }
}

It's using the same iterator for labels and values, and doing a next() twice per row.

Is this a bug?  Am I missing something obvious?

Cheers,

Tim.

Have you looked at the source for OptionTag yet?

The first thing it does is check for a SelectTag in the pageContext.
I believe it is forcing this because it needs to know if it should render it
as "selected".

If you need the functionality of Options, but need to write your own select,
I would suggest using logic:iterate.

Hope that helps.

Anyone know why this is the case - ie why html:options won't accept a regular
html  tag to be enclosed in?

Makes it very frustrating when you don't care about value of select when it's
submitted, but want to use html:options for speed to display a collection.  You
have to add a dummy getter in the action form which seems very cumbersome at the
least.

Cheers,

David

Re: populating list for html:options tag within FormBean

[Damien VIEL]

I think it's what I'm doing ?
companyJob object is doing the DB calls and his methode getAllCompany
returns the ResultSet of the query. Should this methode return the ArrayList
?
Would you give me the subject of the Tread about this subject ?

It is not a good practice to have DB calls in ur Action class. Action Class
belongs to web tier and it should call db layer thru' Business objects via a
Business delegate. There was a good thread couple of weeks ago on this.
After the call is made to the Db and results are returned, u can store the
list as done in the last few lines in this code.

Just my thoughts.

populating list for html:options tag within FormBean

[Gary Bartlett]

Question - 

I saw in an earlier post that someone was populating
the list for an html:options tag within a FormBean. 
My question is how does the FormBean place the list
into the context so it is available to the tag ?  

I realize this is a pretty basic question, but my only
frame of reference here is the example where the jsp
scriptlet creates the list and places it into the
context with pageContext.setAttribute();

Thanks, 

Gary Bartlett

RE: html:options

[Chen, Dean (Zhun)]

I have a similar situation:

I'm trying to display the keys of an enumeration in a drop down list.

The keys are Integers and are stored in a Hashtable
>reports.put(new Integer(reportID), item);

The function getReportsKeys returns  reports.keys();

I have two questions:

1. Can html:options collection be used with an enumeration?

2. How can I display the list of keys in JSP?
I have this, what should go in ___WHAT_GOES_HERE???,
I tried intValue   //from the Integer class, but I get
"javax.servlet.ServletException: No getter method for property
reports.reportsKeys of bean com.gs.ed.sh.GLOBAL"

if there's no solution, would I have to create another class call reportID
with getters & setters?
here's the code


--Select Report
Type--

  

Thanks,

Dean Chen

html:options bug?

[Hoang, Hai]

 
I've been using the html:options tag like following without any problems in
the past.
 







 
 
However, I recently get this weird javax.servlet.ServletException:
PropertyDescriptor: internal error
while merging PDs: type mismatch between read and write methods

 

When I change the code to the following and everything is working fine...Any
ideas?

 



<%

User[] users = (User[])session.getAttribute("allusers");

if (users != null)

{

for (int i = 0; i < users.length; i++)   

{%>

<%=users[i].getName()%>

<%}

}%>



 

Thank you

You have to use the "collection" property of the options tag - read the tag

but it's not going to work

You have to use the "collection" property of the options tag - read the tag
spec:

http://jakarta.apache.org/struts/struts-bean.html

but it's not going to work

Subject: Problem in Html:options tag


Hi
I have an options tag which gets a list of values somehwre around 
111 in number.But while displaying the page it gives an error and 
page is not shown.Everything in my code is correct.Just wanted to 
know is there any restriction on the number of options we can show 
in select box or is there some other way to make it around.





I have GetFamilyList which builds up a list from the table and the 
SetFamilyList and GetFamily and setFamily methods which works 
correctly when I select less values.
Is there any other way to achieve this.

Any help would be appreciated.

Thanks

Re: usage of html:options

[Arron Bates]

The tag Ted mentions is html:optionsCollection, and it's in Struts 1.1

If you have to run 1.0/1.0.1, then what you're doing with the 
bean:define is the standard use. Or, if you have a collection for the 
values, and a value for the labels, then you can just use the 
html:options, with the "property" property pointing at the bean property 
that will yield the value list, and the "labelProperty" pointing at the 
bean property that will be the list of labels. Only thing about this is, 
is that they're separate lists.

But to use the list of beans that themselves hold the label and values, 
then there is no other way but your bean:define usage you already have, 
or the new html:optionsCollection tag.

Arron.

Re: usage of html:options

[Ted Husted]

If the collection is stored on the ActionForm, you have to use
bean:define under Struts 1.0.x 

For Struts 1.1, there is another tag that gets around this.

Trimming strings in html:options

[Bhaskar Gopalan]

Hi,
I am dynamically populating a options field from the database. For this I am
getting an ArrayList
of strings that are formatted as id:value. 

Code:
<%
PipelineFilterForm pipelineFilterForm =
(PipelineFilterForm)session.getAttribute("PipelineFilterForm");
java.util.ArrayList statusOptions = pipelineFilterForm.getStatusOptions();
if(statusOptions != null) {
pageContext.setAttribute("statusOptions", statusOptions,
PageContext.PAGE_SCOPE);
%>

 Select One
 


The options displayed are id:value which is ok. But I want to set the value
of each option
equal to the 'id' part of the string. Is there any way to do this?

Also, line 2 of the code shows how I access the formBean from the form. Is
there any other
way to acheive this?

Thanks,
Bhaskar

Re: html:options Iterator Creation error -

[Ted Husted]

If PersonalForm has a 

Collection getSecurityOptions();

method then it does look OK. 

This shouldn't matter, but you could try a type property with
bean:define

html:options Iterator Creation error -

[Sunder]

Hi, 
I am trying to implement the html:options tag in one of our
applications,

I have a form bean with the following attributes,

private Collection securityOptions = null;
private String security = "Default";

PersonalForm perform = (PersonalForm) form;
Collection list = (Collection) new ArrayList();
for(int i = 0; i<10; i++)
{
list.add(new LabelValueBean("Default","Value"));
}
perform.setSecurityOptions(list);

and finally in my jsp, I try to display the collection using
html:options tag as follows

 
 
  


I get the following error when I try to view the page

Re: Controlling MaxWidth for html:options or html:select?

[theron . kousek]

Hi Aaron:

I tried using a stylesheet but perhaps I am doing it wrong:

My stylesheet class looks like:

.selectStyle
{
font-size: 7pt;
font-family: verdana;
font-weight: bold
   max-width: 110;
}

and the html:select looks like:


   
  

The 2 problems I have is:
1.  The text showing up in the collection is not showing up with the bold
weight.
2.   It ignores my max-width 110 and still decides to show about 300 pixels
for the states collection

:-(

thanks,
Theron

That's a good one actually. Problem is though, you'll never see what's
cut off by the width in IE. NS6 actually shows the whole thing when it
drops down. Quite cool NS!.

Re: Controlling MaxWidth for html:options or html:select?

[Arron Bates]

I'm afraid that there's nothing you can do about it.

Limitation defined by Html, because no horizontal scroll bar will appear 
so users can read the whole string. You'll either have to split it up 
into the different parts or abreviate it in some way.

Controlling MaxWidth for html:options or html:select?

[theron . kousek]

I'm having a hardtime controlling the field-width for a dropdown using
html:select with html:options:

For example:
   

   
  
   

My "states" collection contains states like:
Alaska
Arkansas
etc,...

but there's one that is:
ARMED FORCES CANADA/EUROPE/PACIFIC/AFRICA/MIDDLE EAST/ASIA

Problem I am having is no matter how I try and limit the "width" of the
dropdown, it wants to be as wide as the largest value in my collection..
Is there a way to control this so that you get a "horizontal" scrollbar
when you do the dropdown? In my example above, it's ignoring my "td
width="100" and it seems to be taking up about 300 pixels to display the
largest value  :-(

thanks,
Theron

Re: html:options problem with labelProperty

[keithBacon]

quick wild guess..
one of the calls to getMerchandiseCategoryDescriptions() returns null.
try returning  "it was null" if you are about to return a null.

html:options problem with labelProperty

[Allen Walker]

I have the following:

[html:select property="merchandiseCategory"]
[html:options property="merchandiseCategoryCodes" 
labelProperty="merchandiseCategoryDescriptions"/]
[/html:select]

Now when I take out the labelProperty attribute, all works. When the 
labelProperty attribute is in, I get:

java.lang.NullPointerException at 
org.apache.struts.taglib.html.OptionsTag.doEndTag(OptionsTag.java:296) at 
_jsp._cbmsi._admin._editbookrecord__jsp._jspService(D:\work\resin-1.2.7\webapps\cbmsi\admin\editbookrecord.jsp:101)
 



This worked fine until I moved to Struts 1.0.2. There is nothing wrong with 
my formbean, it contains the "merchandiseCategoryDescriptions" getter on 
the associated form bean.

Thanks for any help.

Re: html:options bug?

[Arron Bates]

The collection attribute needs the bean reference only. The dot notation 
is for your property. Because the collection isn't the bean itself 
you'll have to use a define tag or something to make a bean reference 
directly to your collection, then use that reference in your collection 
attribute.

For your second example... The collection attribute is overriding, and 
ignores the name attribute. It's meant to be the direct link to a bean 
reference that itself is a collection.

html:options bug?

[Lawlor, Frank]

The Struts Options tag seems to have problems accessing collections 
that are in some other object (e.g., your form).  The following dotted
notation should work (I thought) (roleList is an ArrayList):

   

   

or alternatively:

   

   

But both of these result in an error that a bean cannot be found in
roleList.
A workaround is to "cache" the list:

   
   

   

Is this a bug or expected behavior?

You mean you're displaying a list in a table or you are displaying a

The html:options tag works great with forms, it'll initialize the select
box to what's in the form object, and it'll display appropriate labels
and set up the appropriate values on each option.

You can quite easily use the CachedRowSet.toCollection(column) to return
any column of the rowset as a collection. Instead of putting the whole

If your lists are just lists and not select boxes (it's not clear from

CachedRowSet for html:options

Hi,
I am currently retrieving a cachedRowSet from a session bean and
displaying lists using the rowset. I would like to use the struts
html:options tag to do the same, From the documentation, it looks like I
have to put this rowset into a collection and use the same. Is there a

html:select and html:options tags

[Viet Kevin]

Hello all

My question is about the struts html:select and html:options tags

public class xxxForm extends ActionForm 
{
private Person choosed;
private Collection persons;


public get...
// accessors for this attributes are defined but I do not display
// them
}

When creating the form I set the choosed properties to firs instance in the persons 
list
xxxForm.setChoosed(xxxForm.getPersons.iterator.next());

Then I want to display that list in a html page for selecting a person in that list.
The html select must list all the persons AND the chooseen one must be displayed first 
(setting the html-attibute selected="selected" for the choosen one)

The other problem is that I want to use an index (an int that index the instances in 
the list) as the value
of the html option tag (not the name of the person)

so the html produced must be something like : 

 John  
 Henri 
 Max 


I play a lot of time trying to obtain this result with the struts tags 
but never figured out how to do it

Please tell me if it is possible to do or propose me an other solution
but I must have an index in my list so the value in the option tag must 
be an int


And the last question is I can't see what the attribute named tabindex in the 
html:select
tag is used for?

Thx in advance

Tell me if I'm wrong, but it seems to me that the findAttribute(String)

This method "searches for the named attribute in page, request, session (if

html:options

[Luke Studley]

Hi all

This is my first post - so excuse me if it is really basic but I am trying
to get the html:options tag to work as documented. My code looks like:



nameTitles.put("Mr",null);
nameTitles.put("Mrs",null);
nameTitles.put("Miss",null);



.




Where I am declaring a simple map and then trying to use it to populate the
option list. But I get the following error:

javax.servlet.jsp.JspException: No getter method available for property
personTitle for bean under name org.apache.struts.taglib.html.BEAN
at
org.apache.struts.taglib.template.GetTag.doStartTag(GetTag.java:193)
at org.apache.jsp.pagetempl$jsp._jspService(pagetempl$jsp.java:265)
at
org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:107)


What am I doing wrong???!

Finding a value from html:options bean

[Denham, Martin]

Hi,

I have 2 similar forms.  An edit form which allows editing, and another view
form which displays the same data but is read-only.

The read-only form is like the edit form but the html:text have been
removed.

Is it possible to look up the value which should be shown in the select box
from the bean I use which contains all the options.

Part of my edit form is shown below.




My quick and dirty solution is to look it up in the Action and save it to
another String property in the ActionForm, then use that in the jsp.  But I
am sure ther must be a simple way to look it up using struts tags.

Thanks in advance for any help.

I recently had this problem, but I ended up creating the collection as a
separate bean in my Action class.  However, after I got past this, Ted
H. pointed out to me that the phrase from the reference, "the name of a JSP
bean in some scope", could refer to the same name as set in the "name"
attribute of the "action" element in "struts-config.xml".

So, if you look at the "html:options" reference, take the choice of NOT setting
"collection", then set "name" to the name specified in the "action", and
"property" to the name of the field in the ActionForm.  I haven't done this,
but I believe that's what you would do.

Re: html:options with FormBean

[Peter Pilgrim]

There are two ways but the best way is to set up a simple bean
like "LabelValueBean" that has two attribute; the option value and the
option description

public class LabelValueBean {
 String label, descrip ; 
 public String getLabel() { ... }
 public void setLabel( String newValue ) { ... }
 public String getDescription() { ... }
 public void setDescription( String newValue ) { ... }
}

Write a collection and store  LabelValueBean inside it.
Write an action form that allows you get the collection or add
the collection directly to the request scope under a known name.
Then you write your  tags to get all the options
You need to tell  the JavaBean property to get the value ie "label" == 
getLabel()
and the display text "description" == getDescription

Hi,

I'd like to use the  tag to display that Collection.
Could anyone give me an example on how to do that?

something like that??


Thanks.

Re: html:options & collection of beans in FormBean

[Ted Husted]

The ActionForm itself is a bean "in some scope". The name is whatever
you specified in struts-config.

People tend to send the options collection over seperately from the form
(your #1), since it usually a seperate query and sometimes used in more
than one place. But referring to the ActionForm itself should work as
well. You should not have to bother with a bean:define.

html:options & collection of beans in FormBean

[David M. Karr]

I have an ActionForm that has a property which is a collection of beans.  I
obtained this collection in my Action.perform() method.

In my JSP page, I want to display an html:options list where the label is one
property of each of those beans, and the value is another property.

It appears, from the description of the attributes of "html:options", that I
can't directly use the collection, being a property of my ActionForm, to
directly render the options list.

It seems like I want to use the "collection" attribute of "html:options", if I
want one property of a bean to be the label, and another to be the value.
However, it doesn't appear as if I can specify a property of the FormBean for
this, it just has to be a bean "in some scope".

Do I have this correct so far?

It appears that I have two choices:

1. To not have the collection as a property of the ActionForm, but have the
Action.perform() method manually place the collection into a property in
request or session scope.

2. To keep the property in the ActionForm, but do a "bean:define" in the JSP
page to get it into a request or session scope bean.

Is this a correct assessment?

If I do the first one, should I pay attention to the "mapping.getScope()"
value, to decide whether to put the property in "request" or "session" scope?

If these are the two basic choices, what are the design tradeoffs?  Will either
of these "smell bad" after being utilized many times?
