Set bean property values

[Alex Casu]

Hi this is my first thred i hope somebody can help me,
i use struts 1.3,
in a jsp i iterate a bean collection, that may have N objects, and dynamically create a table,
each <tr> have the same inputs with same name but with different value that can be changed from user.
i can't set form-bean properties with the bean properties because i have a collection of bean
how can display the values of different bean properties if i have one bean-form associated ?

sorry for my bad english i hope somebody have understood

any help is appreciated,
tnx

Hi,

Welcome to JavaRanch.

Hope below code snippets may help you.

In Action,

EmployeeManager dao = new EmployeeManager();
List<EmployeeBean> list = dao.getEmpList();
session/request.setAttribute("beanList",list);

In JSP

<tbody>
<logic:present name="beanList">
<logic:iterate id="bean" name="beanList">
   <tr>
     <td><bean:write name="bean" property="id"/></td>
     <td><bean:write name="bean" property="name"/></td>
     <td><bean:write name="bean" property="address"/></td>
     <td><bean:write name="bean" property="mobileno"/></td>
     <td><bean:write name="bean" property="email"/></td>
   </tr>
</logic:iterate>
</logic:present>
</tbody>

Hi Rajagopal thanks for you reply but i've solved, i has something like this

<tbody id="tblDatiContrattoId">
<logic:iterate name="beanCollection" indexId="rIndex" id="record" type="it.gemeaz.affi.common.bean.myBean">
<tr class="<%=classTr%>" json="N" id="tr_<bean:write name ="rIndex"/>">
   <td>
     <logic:notEmpty name="record" property="itemList">
          <html:select property="myItem"  onchange="setRowJSON(this.parentNode.parentNode.id);" > //onchange function set tr json property to S, the tr with json="S" will be update            <html:optionsCollection name="record" property="itemList" value="codice" label="description" />           
          </html:select> 
     </logic:notEmpty>
   </td>
   <td>
     <logic:notEmpty name="record" property="colorList">
          <html:select property="myColor" onchange="setRowJSON(this.parentNode.parentNode.id);" > 
            <html:optionsCollection name="record" property="colorList" value="codice" label="descrizioneCompleta" />           
          </html:select> 
     </logic:notEmpty>
   </td>
   <td>
      ....another select like above
  </td>
   another one....
   another one....
</tr>
</logic:iterate>
</tbody>

every TR is the rappresentation of different bean ex. tr_0 = bean at index 0, tr_1 = bean at index 1 ... and so on..
the user can change one o more inputs value of one o more tr, after save in the combo fields must be selected the new value.
something like html <option value="value" selected="selected" >item 1</option>
ex.

//before user's changes

<tr id="tr_0"><td>item1</td><td>color1</td><td>size1</td></tr>//match with bean at index 0
<tr id="tr_1"><td>item3</td><td>color2</td><td>size5</td></tr>//match with bean at index 1
<tr id="tr_2"><td>item6</td><td>color8</td><td>size6</td></tr>//match with bean at index 2

and so on...

//after user's changes

<tr id="tr_0"><td>item1</td><td>[b]color3[/b]</td><td>size1</td></tr>
<tr id="tr_1"><td>item3</td><td>color2</td><td>size5</td></tr>
<tr id="tr_2"><td>[b]item1[/b]</td><td>color8</td><td>size6</td></tr>

my tryed in this way:

in the end of jsp i call js function like document.onLoad=myFunction();

myFunction(){
//with jstl
get beanCollection and iterate it
//with js
get tbody container and iterate it
match tr and bean having the same index
get all tr select fields and iterate it
if comboField.id == beanpropertyname or form-bean property(it's the same) set values //i think this step is not elegant because i must know what property i need to get//
comboField.value = <c:out value="${bean.property}"/>
}

it works fine
