In this article, it shows you how to customize standard conversion or validation error message in JSF 2.0.Summary GuideFind your message key from jsf-api-2.x.jar, "Messages.properties" file.Create your http://stackoverflow.com/questions/10411773/how-to-customize-jsf-validation-error-message own properties file, and put the same message key you found in above "Messages.properties" file, and override it with your custom error message.Register your properties file in "faces-config.xml", put it as application level.Done.1. Messages.propertiesAll JSF standard conversion and validation error messages are stored in "Messages.properties" file, which can be located https://www.mkyong.com/jsf2/customize-validation-error-message-in-jsf-2-0/ from jsf-api-2.x.jar, "javax\faces\Messages.properties", see figure below : See portion of this "Messages.properties" file ... # =================================================================== # Converter Errors # =================================================================== javax.faces.converter.DateTimeConverter.DATE={2}: ''{0}'' could not be understood as a date. javax.faces.converter.DateTimeConverter.DATE_detail={2}: ''{0}'' could not be understood as a date. Example: {1} ... # ==================================================================== # Validator Errors # ==================================================================== javax.faces.validator.LengthValidator.MAXIMUM={1}: Validation Error: Length is greater than allowable maximum of ''{0}'' javax.faces.validator.LengthValidator.MINIMUM={1}: Validation Error: Length is less than allowable minimum of ''{0}'' ... For example, 1. If maximum length validation failed, JSF gets "javax.faces.validator.LengthValidator.MAXIMUM". If minimum length validation failed, JSF gets "javax.faces.validator.LengthValidator.MINIMUM".2. If date validation failed, JSF gets "javax.faces.converter.DateTimeConverter.DATE_detail". Note If you do not sure which key match to which validator tag, just display the error message once and compare it with "Messages.properties", then you will know which key you want to override. 2.

When having validators on fields, how can I customize the error messages, but https://dzone.com/articles/jsf-validation-tutorial-error for each field in particular. I know about overwritting javax.faces.component.UIInput.REQUIRED, but I don't want my message to sound so general, like `Validation Error: Value is required`. I want my error message to be customized for customize validation each field, like: Username is required Password is required Please repeat password Alex Nedelcu Greenhorn Posts: 15 posted 10 years ago Unfortunately I found that the answer is not so beginner-friendly. According to this article http://www.oracle.com/technology/pub/articles/masterj2ee/j2ee_wk7.html one can customize these error messages by implementing a phase listener. I'm a little dissapointed. Another hack like this for such a simple thing, and I'll dismiss JSF completely, although I do customize validation error feel a relief that at least it is possible. Jeff Albertson Ranch Hand Posts: 1780 posted 10 years ago Hi Alex, I'd be interested in seeing how others do this but this is my approach: 1. Instead of using required="true" (because I don't know how to override that bit of behaviour), I wrote a custom converter: I won't go into how to write and register a custom converter here. Any JSF book will show how to do this. (Why not a validator? Validators are not called on empty fields.) 2. I use the id of the component as the message key for the label text, so in my message bundles I have: firstname=First name ... msg_something_required={0} is required 3. In the converter, the code goes along these lines: public Object getAsObject(FacesContext context, UIComponent component, String string) { if (string==null) { String id = component.getId(); //"firstname" String label = ... lookup id in message bundles //"First name" String message = ... lookup msg_something_required in message bundles and perform formatting //"First name is required" throw converter exception } return string; } Pulling strings out of message bundles is harder than it should be in JSF, but again, any JSF book w

In a continuationof my previous article on Creating JavaServer Faces JSF application in Eclipse, I am posting the next article in the series. This time we will cover details about JSF Validation Model and Handling Errors in JSF. JavaServer Faces technology supports a mechanism for validating the data of editable components. Each component in JavaServer Faces creates Error Messages during the life cycle of JSF and attaches them to FacesContext object. Hence each message is attached to a component in the component tree and the message is displayed into the view at the end of JSF life cycle.Showing Error Messages on ViewJSF provides different tags to handle and display messages on the view. There are two message tags in Sun’s reference implementation of JSF HTML library: h:messages is used to display all messages at once. You can place h:messages tag in start of your form. You may need to display only global messages using h:messages tag. For displaying only global messages set globleOnly attribute of h:messages to true.Use h:message to display message attached to one component. An attibute for=”" can be used to specify the id of a component whose error messages we need to display. h:message is used to display error message next to the component that generated the error. If more then one message is attached to that component, h:message will display the last message.... ... Each message can have a summary description and a detailed description. When using the h:message tag, the default is to sh
