Dear Friends,
I am new to
Struts, and using Struts 1.1
Here i encounter probelom while using Validate method in Form,following are the Details
1.ValidationAction -> Action class
2.ValidationForm ->Form class
Following are the Syntex that is used in ValidationAction class
public ActionErrors validate(ActionMapping mapping,HttpServletRequest request)
{
ActionErrors errors= new ActionErrors();
if(isMissing(getName()))
errors.add("name",new ActionMessage("name.required"));
if(isMissing(getPlace()))
errors.add("place",new ActionMessage("place.required"));
return(errors);
}
in struts-config.xml ths configuration lookes like this
<form-bean name="ValidationForm"
type="manualvalidation.ValidationForm" />
.
.
<actionpath="/Validation"
type="manualvalidation.ValidationAction"
name="ValidationForm"
scope="request"
validate="true"
input="/validation/Validation.jsp">
<forward name="success" path="/validation/success.jsp" />
</action>
<message-resources parameter="MessageResources" />
When i Accessed the page and given submit,
it return the following error in browser
