How to specify custom validate error message in SimpleDateFormat using Spring MVC

Question

In my Smpring MVC application I'm validating dates using SimpleDateFormat as a custom editor in WebDataBinder. When entered date does not match required pattern I get raw error message in my form:errors tag like:

Failed to convert property value of type java.lang.String to required type java.util.Date for property hireDate; nested exception is java.lang.IllegalArgumentException: Could not parse date: Unparseable date: "432345"

My problem is that I want to display on jsp page custom error message something like:

"Date of birth must match "dd/MM/yyyy" pattern"

Here is the code of my @InitBinder:

@InitBinder
protected void initBinder(WebDataBinder binder) {
    SimpleDateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy");
    binder.registerCustomEditor(Date.class, new CustomDateEditor(dateFormat, false));
}

Thanks.

Try registering the following message in your message bundle:

typeMismatch.command.field=Date of birth must match "dd/MM/yyyy" pattern
or
typeMismatch.field = ...

replace command and field with appropriate command object
