Re: load data from db into form

[Mark Lowe]

Okay assuming the following..

<form-bean name="registerFull" 
type="org.apache.struts.validator.DynaValidatorForm">
             <form-property name="id" type="java.lang.Integer" />
           <form-property name="fullname" type="java.lang.String" />
            <form-property name="notify" type="java.lang.Integer" />
</form-bean>

..

<html:text property="fullname" />
<html:text property="id" />
<html:text property="notify />
or if you are nesting you bean which in that case i wouldn't (too 
short).

<form-property name="mybean" 
type="cz.chalu.struts.modules.completeregister.ComplRegisterDTO">

Then assuming that fullname, id, and notify are all properties of 
ComplRegisterDTO.

<html:text property="mybean.fullname" />
<html:text property="mybean.id" />
<html:text property="mybean.notify" />
Cheers Mark

Thanks Mark
I do not know if I understnad well.
No I have in struts config:
<form-bean name="registerFull" 
type="org.apache.struts.validator.DynaValidatorForm">
             <form-property name="prop" 
type="cz.chalu.struts.modules.completeregister.ComplRegisterDTO" />
             <form-property name="id" type="java.lang.Integer" />
           <form-property name="fullname" type="java.lang.String" />
            <form-property name="notify" type="java.lang.Integer" />
...

, action definition:
<action
           path="/Register2"
           
type="cz.chalu.struts.modules.completeregister.LoadDataAction"
           parameter=".main.registerFinish"/>
, LoadDataAction is:
public ActionForward execute(ActionMapping mapping,
                                            ActionForm form,
                                            HttpServletRequest request,
                                            HttpServletResponse 
response)
                   throws Exception, DatabaseException
   {

       LoadDataService service = new LoadDataService();
       ComplRegisterDTO registerDTO = service.loadUser(request);
       BeanUtils.copyProperties(form, registerDTO);
             return (mapping.findForward("success"));
   }
and form:
   <html:form action="/FinishRegister" method="post" 
focus="registerFull">
     <table border="0">
       <tr>
         <td><bean:message key="register.name.Fullname" />:</td>
         <td><html:text property="fullname" /></td>
       </tr>
       <tr>
         <td><bean:message key="register.name.Mail" />:</td>
         <td><html:text property="mail" /></td>
       </tr>
       <tr>
         <td><bean:message key="register.name.MailNotification" 
/>:</td>
         <td valign="top">
           <html:radio property="notify" value="1" ><bean:message 
key="register.name.MailNotifYes" /></html:radio>
           <html:radio property="notify" value="0" ><bean:message 
key="register.name.MailNotifNo" /></html:radio>
         </td>
       </tr>
...

and i got exception

ServletException: No destination bean specified

what is wrong?

Your from bean definition is the most useful thing you can provide to 
answer this..

if in your formBean definition or in the actionForm class you've got 
type

<form-property name="myprop" type="com.whatever.ComplRegisterDTO" />

Then you're on the right lines.. But you're nesting so you jsp needs 
to be more like

ComplRegisterDTO myObj = whatever...

theForm.set("myprop",myObj);

.. or if you dig beanutils

BeanUtils.copyProperties(theForm, myObj) ; //a bit silly in the this 
case,

<html:text property="myprop.fullname" />

......Other wise if you've got (recommended).

<form-property name="fullname" type="java.lang.String" />
<form-property name="mail" type="java.lang.String" />
DynaACtionForm theForm = (DynaActionForm) form;

theForm.set("fullname","Joe Bloggs");
theForm.set("mail","[EMAIL PROTECTED]");
Does this help?
