how to prepopulate a form using form:input tag?

[hernan rodriguez]

hi, i need some help, need to prepopulate a form , just take the data from the db and put them into a form. I tried using the "value" attribute but it didn't work, i got an error: Undefined attribute name "value". In the form should appear the user's credentials so he can edit them... but i don't know how to do it...,
there's is also select tags in the form.

thanks

regards

What does your Controller method look like? How about your jsp file? We can't figure it out unless we see that information.

My index.jsp:

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<%@ taglib uri="http://www.springframework.org/tags/form" prefix="form"%>
...
<c:if test="${fn:length(attribute) > 0}">

<form:form name="form" method="POST" commandName="user" action="form_onsubmit.htm">

     <form:input path="name"  />

     <form:radiobutton path="gender" value="M" /> 
     <form:radiobutton path="gender" value="F" /> 

     <form:select path="day"> 
	     <form:option value="" label="-  " />					
	     <c:forEach var="i" begin="1" end="31" step="1">
                      <form:option value="${i}" label="${i}  " />
     	     </c:forEach>			
     </form:select> 

</form:form>

</c:if>
...

My controller:

...

@RequestMapping(method = RequestMethod.POST) public ModelAndView form_onsubmit(HttpServletRequest request, HttpServletResponse response, @ModelAttribute("user") User user, BindingResult result) throws Exception {

userValidator.validate(user, result);

modelMap.addAttribute("attribute", "attribute");

return new ModelAndView("index",modelMap);

}
