Hi Prathima,

You can write Edit validate rule. There you can validate the domain name should be “@example.com” and add this edit validate rule that property.

Please find the below code:

if (theValue == null || theValue.trim().equals("")) return false;

String mail="^[_A-Za-z0-9-]+(\\.[_A-Za-z0-9-]+)*@[A-Za-z0-9-]+(\\.[A-Za-z0-9-]+)+(\\.[A-Za-z]{2,})$";

  java.util.regex.Pattern pattern=java.util.regex.Pattern.compile(mail);

java.util.regex.Matcher matcher = pattern.matcher(theValue);

  String add = theValue;

int domain=theValue.indexOf('@');

String x=theValue.substring(domain +1,theValue.length());

if(!matcher.matches() || !x.contains("example.com")){

 theProperty.addMessage("Entered email domain name should be example.com ");

 return false;}

else

  return true;

Let us know if this helps.

Thanks
