Re: Drop-Down List - Cannot Retrieve Definition From Form Bean Null
Hi Caroline,
The list should not be a session attribute.
Instead, you should declare member variables inside your Form bean
as follows..
public class EditorForm {
String [] options;
EditorBean editor;
public String [] getOptions() {
return options;
}
public EditorBean getEditor() {
return this.editor;
}
}
In your JSP page,
html:select property=editor
html:options property=options /
/html:select
Hope this helps you...
Ajay
My drop-down list got an error message:
org.apache.jasper.JasperException: Cannot retrieve
definition for form bean null
I have tried to display the drop-down list in two
ways:
First:
html:select size=1 property=editor
multiple=false
html:options collection=editors property=name
labelProperty=name/
/html:select
Second:
bean:define id=editorsList name=editors
scope=session /
html:select property=editor size=1
multiple=false
html:options collection=editorsList
labelProperty=name property=value/
/html:select
The editors is a Collection of EditorBean passed to
the JSP this way:
HttpSession session = request.getSession();
session.setAttribute( editors, editors );
and Editor Bean is:
public class EditorBean
{
private String name;
public EditorBean() {}
public EditorBean( String name )
{
this.name = name;
}
public String getName() {
return name;
}
public void setName( String name ) {
this.name = name;
}
}

Swaroop,
I am trying to implement the way you have mentioned for populating drop downs.
I'm getting the following exception:
javax.servlet.ServletException: Exception thrown by getter for property countries of
bean dropdown
Here's the code that I'm using:
jsp:useBean id=dropdown scope=application class=com.xxx.DropDownCollections
/jsp:useBean
bean:define id=countries name=dropdown property=countries toScope=request /
Bean Class:
package com.xxx;
public class DropDownCollections {
private ArrayList countries = new ArrayList();
public Collection getCountries() {
//ArrayList list = new ArrayList();
try{
countries.add(new LabelValueBean(Australia, 1000));
countries.add(new LabelValueBean(New Zealand, 1001));
countries.add(new LabelValueBean(India, 1003));
} catch (Exception ex) {
ex.printStackTrace();
}
return countries;
}
public void setCountries(Collection options) {
// No op, here to satisfy bean-ness.
}
}
Any possible solution? Please inform.

You can actually use an html:select instead of a nested:select

public ArrayList getCountries() {
// here u can populate the

}
public void setCountries(ArrayList countries)

It is actually calling the getter method.. but something is happening

countries.add(new LabelValueBean(New Zealand, 1001));

RE: drop-down list help
Swaroop,
I have given a system.out.println statement in catch block (as follows):
public ArrayList getCountries() {
ArrayList countries = new ArrayList();
try{
countries.add(new LabelValueBean(Australia, 1000));
countries.add(new LabelValueBean(New Zealand, 1001));
countries.add(new LabelValueBean(India, 1003));
} catch (Exception ex) {
System.out.println(.exception);
ex.printStackTrace();
}
return countries;
}
But nothing is printed on app. server console except for the exception that I've
mentioned before.

RE: drop-down list help

Same error! I modified the function as follows:
public Collection getCountries() {
ArrayList countries = new ArrayList();
try{
countries.add(new LabelValueBean(Australia, 1000));
countries.add(new LabelValueBean(New Zealand, 1001));

In my jsp page, I have given println statements to trace out where exactly the problem
is:

jsp:useBean id=dropdown scope=application
class=com.xxx.utils.DropDownCollections/
% System.out.println(Step 2); %
bean:define id=countries name=dropdown property=countries toScope=request/
% System.out.println(Step 3); %
The output on the console is:

Step 1 and Step2 statements are printed on the console but Step 3 is not printed.

RE: drop-down list help
I don't think u r proceeding the right way.. When u removed property
what has happened is u have eliminated the getCountries method call..
and thus u r able to see ur 3rd print statement. U need to have the
property cauz the collection u need is an attribute of the
DropDownCollections class, not the DropDownCollections class
itself..(which is why its saying Cannot create iterator for
DropDownCollections)..
Internally it creates an iterator out of the collection returned which
its not able to create cauz there is no collection returned at all..
I doubt ur new LabelValueBean is throwing an error. Please do remove the
exception handling from ur class..

Yes I know that there is something wrong in bean:define. As the next

Same error! I modified the function as follows:
public Collection getCountries() {
ArrayList countries = new ArrayList();
try{
countries.add(new LabelValueBean(Australia,
1000));
countries.add(new LabelValueBean(New Zealand,
1001));
countries.add(new LabelValueBean(India, 1003));
} catch (Exception ex) {
System.out.println(.exception);
ex.printStackTrace();
}
return countries;
}
In my jsp page, I have given println statements to trace out where
exactly the problem is:
% System.out.println(Step 1); %

I have given a system.out.println statement in catch block (as follows):
public ArrayList getCountries() {
ArrayList countries = new ArrayList();
try{
countries.add(new LabelValueBean(Australia,
1000));
countries.add(new LabelValueBean(New Zealand,

But nothing is printed on app. server console except for the exception

You are right. I have commented LabelValueBean statements and I got the displayed with
a blank dropdown list.
My bean method is now as follows:
public Collection getCountries() {
ArrayList countries = new ArrayList();
//countries.add(new LabelValueBean(Australia, 1000));
//countries.add(new LabelValueBean(New Zealand, 1001));
//countries.add(new LabelValueBean(India, 1003));
return countries;
}
How to get data into this if I don't use LabelValueBean. What have you used? Can you
post your code for DropDownCollections.java please?

Did u remove the try catch block as I said.. If u remove that u will

Subject: RE: drop-down list help
Swaroop,
You are right. I have commented LabelValueBean statements and I got the
displayed with a blank dropdown list.
My bean method is now as follows:
public Collection getCountries() {
ArrayList countries = new ArrayList();
//countries.add(new LabelValueBean(Australia, 1000));
//countries.add(new LabelValueBean(New Zealand, 1001));
//countries.add(new LabelValueBean(India, 1003));
return countries;
}
How to get data into this if I don't use LabelValueBean. What have you
used? Can you post your code for DropDownCollections.java please?
Sriram

I don't think u r proceeding the right way.. When u removed property
what has happened is u have eliminated the getCountries method call..
and thus u r able to see ur 3rd print statement. U need to have the
property cauz the collection u need is an attribute of the
DropDownCollections class, not the DropDownCollections class
itself..(which is why its saying Cannot create iterator for
DropDownCollections)..
Internally it creates an iterator out of the collection returned which
its not able to create cauz there is no collection returned at all.. I
doubt ur new LabelValueBean is throwing an error. Please do remove the
exception handling from ur class..

Swaroop,
I have made a change to bean:define.
I removed 'property' -- (If not specified, the bean identified by name
is given a new reference identified by id.)
Then my println statements are working till Step 3. So, I presume the
previous problem is solved.
There's some problem now with html:select.
Trying to debug that:

Yes I know that there is something wrong in bean:define. As the next
step remove the try {} catch{} block in the getCountries method. Let it

try{

Oops sorry.. Sriram.. since the problem is with LabelValueBean
use the separate bean which u have created
html:options property=CountryID labelProperty=CountryName/

hi,
i'm using struts 1.1 and so i'm trying to use lablevaluebean.
u can create a simple javabean with two variables, with set,get methods
and use it
it is as easy
- so in my bean, i should have get and set methods for CountryID and
CountryName.
And how should I refer them in html:options tag?
html:options property=CountryID labelProperty=CountryName/
correct?

Good afternoon, I have just changed one of my forms to use the DynaValidatorForm and I'm not convinced of the benifits of it! I remove the Form with the getX() and setX() methods and also validate() and reset(), so I have less classes floating about. But now I don't have the reset method which we were using to pre populate some of the jsp form. Building the Form class was not really a problem using the generate getters and setters functionality of Eclipse, which makes me wonder what are the real benifits of DynaValidatorForms?

RE: drop-down list help
Hi, Rick: Take a look at http://www.reumann.net/do/struts/main In Lesson II, you'll find an example of how to use the html:select tag Lesson II-4 Create ActionForm - The UI element for entering a value into the department field will be a drop-down list. Lesson II-6 Create DepartmentBean - This bean will be used to represent options for the drop-down list. Lesson II-8 Create EmployerService - shows how the list of departments is created. Lesson II-9 Create SetUpEmployerAction - this is where the list of options is put into the session context. code: -- Collection departments = service.getDepartments(); HttpSession session = request.getSession(); session.setAttribute( departments, departments ); -- Lesson II-14 Create employeeForm.jsp - shows how the html:select and html:options is used to present a drop-down list of departments. Note the property and labelProperty attributes in the html:options tag: both id and description are properties of the DepartmentBean created in II-6. The collection attribute is the name departments which was used when the list of DepartmentBeans was added to the session context (II-9). --- Rick Col [EMAIL PROTECTED] wrote: Hi, Swaroop: I have a question about your implementation, do we still need to implement an actionForm class for the following drop down list? regards, --- Swaroop George [EMAIL PROTECTED] wrote: jsp:useBean id=dropdown scope=application class=com.xxx.DropdownCollections /jsp:useBean bean:define id=months name=dropdown property=months toScope=request/ html:select property=month html:options collection=months property=key labelProperty=value/ /html:select Hi this is a part of the page I developed..

But if you need to show the 3rd option as slelected in the list how do we do that in struts? thanks a lot in advance Mahesh If you use the struts-html tags, and use a form bean which is setup with the correct defaults, struts does this automagically. So for example, say the drop-down list is a choice between a, b and c, and the property is called 'choice', and you want c to be the default, then you just make sure that the default value of choice in your form bean is c. If you need me to clarify further, email me and I'll send you some code to show what I mean.

When adding options to a select that are stored in a database, we have the
action class look-up the necessary information, store it in a bean, place the

the source (the bean) and the property (database column) that should be used to
populate the select.
This gaurentees that the data in the select list is up to date.

Re: Drop-down list
Add the attribute to your tag like so:
html:select ... multiple="true" ...
and make sure the corresponding property in your form bean is an array of
values.
See the docs for more details:

Add the attribute to your tag like so:
html:select ... multiple="true" ...
and make sure the corresponding property in your form bean is an array of
values.
See the docs for more details:
http://jakarta.apache.org/struts/struts-html.html#select
Hope this helps.

When adding options to a select that are stored in a database, we have
the

place
the
bean in the request / session, and then use a taglib on the page that
specifies
the source (the bean) and the property (database column) that should

used to
populate the select.
This gaurentees that the data in the select list is up to date.

Get the content at the top of the JSP page.

pageContext.setAttribute("nameSuffixTypes",
getServletContext().getAttribute("nameSuffixTypes"));

Place this where you want the Drop Down List on the JSP page.
html:select property="suffix"

O.k. so I declare it like so:

Then I get it:

}
Then I set it:

I'd remove all the square brackets. If you want to keep them, the
parameter
type in setProviderName should be String[].
I don't know for sure though.

What I do in my real applications is to load in the options for each combo box at startup time, and store each as servlet context attributes. That way, everyone uses the same copy without having to go to the database every single time. If the values do change occasionally, and you don't want to shut down your app to recognize them, you could even define an Action that reloads them. Craig
