In the jsp code u given onsubmit="return validateCustomerForm(this); but
in validator-user.xml the form name is custForm, so replace that with
onsubmit="return validateCustForm(this);
Thanks,
Srinivas.

Hello everybody,
I'm new to Java. I'm working on Struts now. I got this application
from one struts PDF. I've one jsp for customer details as follows:
CustomerDetails.jsp:
<%@ page contentType="text/html;charset=UTF-8" language="java"%>
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html"%>
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean"%>
<html:html>
<head>
<html:base/>
</head>
<body>
<html:form action="submitCustomerForm" onsubmit="return
validateCustomerForm(this);">
<bean:message key="custForm.firstName"/>
<html:text property="firstName" size="16" maxlength="16"/>
<br>
<bean:message key="custForm.lastName"/>
<html:text property="lastName" size="16" maxlength="16"/>
<br>
<html:submit value="Submit"/>
</html:form>
</body>
</html:html>
CustomerForm.java:
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionErrors;
import org.apache.struts.action.ActionError;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.validator.ValidatorForm;
import javax.servlet.http.HttpServletRequest;
public class CustomerForm extends ValidatorForm
{
private String firstName;
private String lastName;
public CustomerForm(){
firstName="";
lastName="";
}
public String getFirstName(){
return firstName;
}
public void setFirstName(String fn){
this.firstName=fn;
}
public String getLastName(){
return lastName;
}
public void setLastName(String ln){
this.lastName=ln;
}
}
CustomerAction.java:
import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;

public class CustomerAction extends Action
{
public ActionForward execute(ActionMapping mapping,ActionForm
form,HttpServletRequest request,HttpServletResponse response) throws
Exception{
if(isCancelled(request)){
System.out.println("Cancel Operation Performed");
return mapping.findForward("mainpage");
}
CustomerForm custForm=(CustomerForm) form;
String firstName=custForm.getFirstName();
String lastName=custForm.getLastName();
System.out.println("Customer First name is "+firstName);
System.out.println("Custoemr Last name is "+lastName);
ActionForward forward=mapping.findForward("success");
return forward;
}

Upto now it's working fine. But it's not displaying the error message
that I've mentioned in the properties file. This file is as follows and
is in WEB-INF/classes.
App1Messages.properties:
custForm.firstName=First Name
custForm.lastName=Last Name
errors.required=Required
validator-rules.xml
<!DOCTYPE form-validation PUBLIC

msg="errors.required"/>

validator.xml
<!DOCTYPE form-validation PUBLIC

<formset>
<form name="custForm">

</form>
</formset>
</form-validation>
I've my success.jsp and failure.jsp.
When I don't enter data into firstname and lastname, the form is
displayed, but the error message is not displying. validator.xml is
working fine because if I don't give any one or both of first name and
last name it's displaying the empty form and if I give both, success.jsp
is displaying. In some struts pdfs I've seen that if validation errors
occur, the JSP u menthioned in input attribute is displayed with the
errors taken from properties file. Is is true or not? If so, why did the
author used the Failure.jsp again? Please clear me why the message is not
coming from properties file. Is the error in properties file or
validator-rules.xml or some other.
Thanks and regards,
Saritha
