JSF validation. can this be simplified?

Question

I have a simple form with a bunch of fields. each of them is required, and each has a different name:

• city
• state

when the form is submi

Answer 1

Either use requiredMessage attribute

---

Or use label attribute and supply a custom required message template.

with a CustomMessages.properties in the classpath which contains the custom message template

javax.faces.component.UIInput.REQUIRED = {0} is required.

The {0} will be substituted with the value of the label attribute. You can find an overview of all keys in the JSF specification (e.g. JSF 2.0 spec - chapter 2.5.2.4). Declare the message properties file in faces-config.xml as message-bundle:

    com.example.CustomMessages

(assuming that it's in the package com.example, you can name it whatever you want)

For more message template keys, check the JSF specification.
