javax.servlet.ServletException: BeanUtils.populate
Hello all,
Although I have used Struts for five years, I have been facing a trouble since Monday and I don't understand what's happening...
So may I ask for some help in this mailing list ?...
I rather prefer asking before drafting a long mail. :)
Sincerly,

If it's Struts-related, sure.

Dear Li,
Thank you for your help. You are right : I should have avoided using arrays. I decided to turn all of them to List, it is easier to add elements on them.
I tried using your AutoList class, then I have less problems, but some exceptions remain. I will work on them tomorow, as I will go to cinema this evening :)
Those exceptions are due to lacking setters and getters.
I will let you know soon.
Thanks a lot again ! :)

What happens when
(1)liste is null
or
(2)liste is filled by null element
or
(3)index accessed is out of bound?

Li,
I think the issue is here is most likely point 3. When the form is submitted, I suspect struts is trying to call getListe(int) to retrieve a Personne bean before calling the respective setters.
So in this case, Dominque probably just needs an additional getter in the action form that will return the required bean:
public Personne getListe(int i) {
return (Personne) liste[i];
}
Peter.

Subject: Re: javax.servlet.ServletException: BeanUtils.populate
I think the reason of the Exception maybe:
(1)the data you post is named like "liste[0].nom"
(2)Struts1 accept this http param, and try to translate it to a form property, by using a lib named Apache Commons BeanUtils
See: http://commons.apache.org/beanutils/
(3)BeanUtils treats nested property access likes "liste[0].nom"
as some chained java method invokes, like:
targetBean.getListe[0].setNome(someValue)
(4-1)If you did not initialize the array liste, it will be a null, so of cause "getListe" will get a null, and then, "getListe[0]" should throw a NullPointException
(4-2)If you initialized the array, but there is no item in it, then "getListe[0]" should throw an IndexOutOfBoundsException
(4-3)If you initialized the array, but the items in it is null, then "getListe[0]" will get a null, and then "setNome(someValue)" should throw a NullPointException
So, you should initialize the array, and items in it, before you can capture data posted from client side.
Years ago, I meet the same problem. But I used List instead of array.
So I created a new class named "AutoList". When you call the "get(index)" method on it, it will create a new item instance if the item dose not exist yet.
By using this AutoList, when BeanUtils try to invoke method likes "getListe(0).setNome(someValue)", the item instance will be created automatically if need.
In your case, my suggest is:
(1)use AutoList, instead of Array
Or
(2)Since you have done the array/item initialization in the the method "setNom(int index , Personne nom)", so you can use this method instead of "getListe[0].setNome(someValue)".
Which mean, in html side, the data name should be "nom[0]" instead of "liste[0].nom"
How ever, I recommend AutoList solution strongly, because I believe this is a very common problem in Struts1.
You may meet it somewhere else, so AutoList class will be very convenient.
And also, if you use AutoList, you don't have to change the data name on the html side, which means, you can use struts tag lib as normal.
If you need this AutoList class, I can send it to you.

There will be only one class, which will be the class of the elements
in the List.
I just want to find the Constructor with the least parameters if there
are more than one constructors for this class.
Once I get the constructor, I can use it to create instance and append
it to List automatically. This is the final purpose of the AutoList
class.

The day after Black Friday and most folks are still at the WalMart so I'll take a stab at some testcases
private E createElementByConstructor() {
try {
Constructor<E>[] constrArray = (Constructor<E>[]) elementClass
.getConstructors();
Constructor<E> constructor = null;
Class[] paramTypes = null;
for (Constructor<E> constr : constrArray) {
if (constructor == null) {
/*this is executed first which is fine */
constructor = constr;
paramTypes = constr.getParameterTypes();
/*constr ParameterType (Class) count (e.g. 0) is less than number of Classes stored in local var paramTypes (e.g. 1) */
} else if (constr.getParameterTypes().length < paramTypes.length) {
constructor = constr;
paramTypes = constr.getParameterTypes();
}
}/* Testcase execution 1st pass Class is Class1 with 1 parameter named fu*/
Class=Class1 parameter=fu
Constructor is now Class1(fu)
paramTypes.length is now 1
/* Testcase execution 2nd pass Class is Class2 with 0 parameters*/
Class=Class2 0 parameters so constr.getParameterTypes().length()==0 < paramTypes 1
Constructor is now Class2();
paramTypes.length is now 0
/* Testcase execution 3rd pass Class is Class2 with 2 parameters parameter=fu and parameter=bar */
Class3 parameter fu, parameter bar so constr.getParameterTypes().length()==2 < paramTypes 0 FAILS!!!!
assignments to variables of constructor and paramTypes are bypassed
Constructor is STILL Class2();
paramTypes.length is STILL 0
is this what you intend?

Hello Peter,
Thanks for your reply.
You may download the project at this URL : http://athe.pagesperso-orange.fr/EssaiA.zip
zip file contains Java sources in /WEB-INF/src :-) you will find a small part of the real project, this one is very big.
Here's the form bean :
package bean;
import org.apache.struts.action.ActionForm;
public class PageFormulaire extends ActionForm {
/**
*
*/
private static final long serialVersionUID = 1L;
private Personne liste[];
public Personne[] getListe() {
return liste;
}
public void setListe(Personne[] liste) {
this.liste = liste;
}
public void setNom(int index , Personne nom) {
if (liste == null)
liste = new Personne[index + 1];
if (liste.length <= index) {
Personne[] t = new Personne[index + 1];
int i = 0;
while (i < liste.length) {
t[i] = liste[i];
i++;
}
liste = t;
}
liste[index] = nom;
}
public Personne getNom(int index) {
if (liste == null)
liste = new Personne[index + 1];
if (liste.length <= index) {
Personne[] t = new Personne[index + 1];
int i = 0;
while (i < liste.length) {
t[i] = liste[i];
i++;
}
liste = t;
}
return liste[index];
}
}
Here's Personne bean :
package bean;
import org.apache.struts.action.ActionForm;
public class Personne extends ActionForm {
/**
*
*/
private static final long serialVersionUID = 1L;
private String nom;
private String prenom;
public String getNom() {
return nom;
}
public void setNom(String nom) {
this.nom = nom;
}
public String getPrenom() {
return prenom;
}
public void setPrenom(String prenom) {
this.prenom = prenom;
}
}

No problem, Dave.
Any idea about my problem ?...
As I'm supposed to release this application on the 15th December, I'm getting worse... I found a solution, but I really want to understand my error.
Thanks,
Dom

Re: javax.servlet.ServletException: BeanUtils.populate
Posted by Dominique JUSTE <dj...@yahoo.com>.
Thank you Dave,
Let me show you the generated HTML file :
<body>
<table>
<form name="pageForm" method="post" action="/EssaiA/traitement.do">
<tr>
<td>Nom</td>
<td><input type="text" name="liste[0].nom" value="1"></td>
<td>Prénom</td>
<td><input type="text" name="liste[0].prenom" value="0"></td>
</tr>
<tr>
<td>Nom</td>
<td><input type="text" name="liste[1].nom" value="9"></td>
<td>Prénom</td>
<td><input type="text" name="liste[1].prenom" value="2"></td>
</tr>
.....
</body>
We see the indexed liste (liste[0], liste[1], ...).
So, what may I do to indicate that form contains an indexed property ? In which file(s) ?

There's nothing in the form that indicates it's an indexed
property/collection.

Re: javax.servlet.ServletException: BeanUtils.populate
Posted by Dominique JUSTE <dj...@yahoo.com>.
Hello all,
Thanks a lot for your replies. As I'm French, I hope I will clearly expose my problem. It has been a long time since my last English draft. :)
I've worked for one month on an application. It was created with Woody framework, which is no longer supported. Consequently my mission is to turn it to Struts. Work is almost completed, but there is one problem left, I've been trying fixing it since Monday but I can't do anything, I have a Beanutils exception :-((.
The application is composed of MySQl 5.0, Hibernate 3.0 and Struts 1.3.10. My problem is on a formular, hence Struts.
I have a two beans :
- Personne (French translation of Character) with String attributs name and firstname,
- PageFormulaire (extends ActionForm), with only one attribut, Personne[] listP.
**I'm sure the exception is caused by this dynamic array.** If I put an unique bean in PageFormulaire, application perfectly works.
Both beans have setters and getters but I created in PageFormulaire two more :
- public void setNom(int index , Personne nom)
- public Personne getNom(int index)
An action instanciates a PageFormulaire bean, fills in with datas in MySQL, puts it in request then calls a JSP. That's OK, the formular appears with the datas. But when clicking submit button, application crashes, and shows this accursed exception :

<%@ taglib uri="/WEB-INF/tld/struts-html.tld" prefix="h" %>
<h:html>
<head>

<n:iterate name="CLE" property="liste">
<tr>

<td><n:text property="nom"/></td>
<td>Prénom</td>
<td><n:text property="prenom"/></td>
</tr>
</n:iterate>
<tr>
<td colspan="4"><n:submit value="Enregistrer"/></td>
</tr>
</table>
</n:form>
</body>
</h:html>
I thought I forgot the put the bean on session scope, but although I write it on struts-config.xml, nothing to do...
<form-beans>
<form-bean name="pageForm" type="bean.PageFormulaire"/>
</form-beans>
<action-mappings>
<action path="/traitement" name="pageForm" type="presentation.Traitement" scope="session"/>
</action-mappings>
Note : class pathes are obviously correct :)
So, does anyone have an idea ?... If necessary, I may send by mail the WAR files containing all Java sources.
Thanks for your help.
Sincerly,
Dominique
