Hi Jerry,


I am not getting any exceptions in the console...but while displaying errors in jsp page...they are not getting displayed properly...


following are the messages getting diaplyed on jsp Page


command=com.person.formBean.Person@1fbe88
org.springframework.validation.BindingResult.comma nd=org.springframework.validation.BeanPropertyBind ingResult: 2 errors Error in object 'command': codes [firstName.emptyerror.command,firstName.emptyerror]; arguments []; default message [null] Error in object 'command': codes [lastName.emptyerror.command,lastName.emptyerror]; arguments []; default message [null]

where Person is the command i'm using and firstName,lastName are properties in that...


Thanks in advance.....

Hi,

I want to see ur JSP code containing the properties firstName,lastName.

or

Tell me, have u used the following attribute in form tag, commandName="---"

[bdontu]

If i use below code for dispalying errors i'm not even getting them displayed in my JSP:

CODE :
------

<spring:bind path="personForm.*">
<c:forEach items="${errorMessages}" var="errormsg">
<c:out value="errormsg"/>
</c:forEach>
</spring:bind>


But if i use

<spring:bind path="personForm.*">
<c:forEach items="${errorMap}" var="msg">
<c:out value="${msg}"/>
</c:forEach>
</spring:bind>

i'm able to display the following as error messages



personForm=com.person.formBean.Person@57df5 org.springframework.validation.BindingResult.perso nForm=org.springframework.validation.BeanPropertyB indingResult: 2 errors Field error in object 'personForm' on field 'firstName': rejected value []; codes [firstName.emptyerror.personForm.firstName,firstNam e.emptyerror.firstName,firstName.emptyerror.java.l ang.String,firstName.emptyerror]; arguments []; default message [First Name should not be Empty!] Field error in object 'personForm' on field 'lastName': rejected value []; codes [lastName.emptyerror.personForm.lastName,lastName.e mptyerror.lastName,lastName.emptyerror.java.lang.S tring,lastName.emptyerror]; arguments []; default message [LastName should not be Empty!]


what i used in controller is:

if (null != errors && null != errors.getModel()) {
//check for existance of errors
mav.addObject("errorMap",errors.getModel());
return mav;
}


and i'm using following code to configure my poperties files in application context xml file

<bean id="messageSource"
class="org.springframework.context.support.Reloada bleResourceBundleMessageSource">
<property name="basenames">
<list>
<value>/WEB-INF/resources/person</value>
</list>
</property>
</bean>


person.properties contains


firstName.emptyerror=LastName is required
lastName.emptyerror=LastName is required

please lety me know the wrong place....do i need to change my resourcebundle in applicationcontext.xml file????



Thanks in advance....

I'm facing similar problems as member have discussed previously..but there is some difference I'm trying to vaildate nested property..


My Validate method

public void validate(Object obj, Errors errors) {
ElementBean elembean = (ElementBean) obj;
HuYdgElementsT element = elembean.getYdgElements();
if (element == null) {
//errors.rejectValue("Element", "error.Element.not-specified", null,"Value required.");
} else {
errors.pushNestedPath("ydgElements");
if(element.getElementTitleC()==null||element.getEl ementTitleC().equals("")){
errors.reject("error.elementTitleC");
}
errors.popNestedPath();
}
}


Exception Occuring
org.springframework.web.bind.ServletRequestBinding Exception: Errors binding onto object 'command'; nested exception is org.springframework.validation.BindException: org.springframework.validation.BeanPropertyBinding Result: 1 errors
Error in object 'command': codes [error.elementTitleC.command,error.elementTitleC]; arguments []; default message [null]


Please provide some sample code if possible

Thanks in Advance

Hi

paste u r jsp and controller code from where you r calling valiadtor.....

[prande]

Controllers Code where validator is getting called

public ModelAndView submitForm(HttpServletRequest httpServletRequest,
HttpServletResponse httpServletResponse, ElementBean command) {
logger.info("Entered addElement Method###################");
ServletRequestDataBinder binder;
ModelAndView mav= null;
try {
binder = createBinder(httpServletRequest, command);
errors = binder.getBindingResult();
if(errors.hasErrors())
{
mav = new ModelAndView("Multi",errors.getModel());
}
mav =new ModelAndView("Multi","elementBean",command);

}catch (Exception e) {
e.printStackTrace();
}
return mav;
}

Form in the JSPhaven't wrriten anything yet to print errors

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix="spring" uri="http://www.springframework.org/tags"%>
<%@ taglib prefix="springform" uri="http://www.springframework.org/tags/form"%>
<springform:form name="elementForm" method="post" action="/Univ/Multi.htm?testParam=submitForm" commandName="elementBean">

spring mappings

</property>
<property name="elementBO" ref="elementBO"></property>
<property name="validators"><list><ref bean="elementFormValidator"/></list></property>
</bean>

I think u have to use commandName instead of ydgElements...in jsp input path elements

and tell me the type of errors variable u r using....
