Assuming you've defined your message bundle in faces-config.xml: ApplicationResources ... You can add your custom messages to (in this case) WEB-INF/classes/ApplicationResources.properties, and leave messages.properties alone. -- Wendy - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Other ideas and > suggestions are welcome! Wendy's technique works fine, although it would be nice if Commons Validator would read more than one resource bundle file without needing to extract it and add the file to WEB-INF/classes yourself (your reading of the ordering requirements is correct). As for doing things in pure JSF validators (either a separate Validator implementation or as a validation method pointed to with a method binding), Shale does offer some help for formatting the messages. There are two classes in the org.apache.shale.util package for this purpose: * LoadBundle - Loads a resource bundle and exposes it as a Map (similar in spirit to what the tag does in a page, but making the messages available programatically as well. * Messages - Utillity for getting locale-specific messages from a set of resource bundles, including parameter substitution, similar to what Struts Action Framework provides with MessageResources. Both of these classes are pure POJOs designed to be configured with setter injection, so it is very easy to configure them as managed beans (normally in application scope). See the class level javadocs of these two classes for examples. HTH, > -- > Wendy > http://wiki.wsmoak.net/cgi-bin/wiki.pl?ShaleValidator Craig

This is an interesting question because I have a custom validator in a Struts app that does exactly that. Here's what I came up with, though I would advise waiting for Craig to comment on whether he intended for this to happen. :) I added another to validator-rules.xml: The ValidationUtil.isDate method takes a String and returns true/false (boolean). Left to its own devices, oas.validatorCommonsValidator uses the (localized) messages.properties file in org.apache.struts.validator (inside shale-core.jar). Since I know the Servlet spec requires that things in WEB-INF/classes be loaded before things in WEB-INF/lib, I extracted the messages.properties file from shale-core.jar, to WEB-INF/classes/org/apache/shale/validator/, and added my new message to it. In the JSP: At least for simple validations, it appears to work fine. It has advantages over all of the 'pure JSF' methods that I investigated-- I certainly don't want to write a custom Validator, and even a simple method binding in the 'validator' attribute of a component means you're responsible for formatting the error message. But if you need more/different parameters than the ones provides, then I do think you'd need to write your own custom JSF Validator and tag, or possibly extend the ones in Shale. I'm going to open a couple of enhancement tickets for things like including validator-rules.xml in shale-core.jar so that you don't have to find and include a copy in your webapp to use the provided validators, and making the the name and location of both the messages and the validation rules file(s) configurable.

custom server side validation in shale
Hi all, Please let me know about how can we do server side validation in shale. Like user validation, when user enters some value that time we need to check with database whether that is correct one or not. If not that will through a alert not message on the screen.
