Customizing the Client-side JavaScript validation message
UDTT uses Dojo to provide basic client-side validations. If you want to customize the validation message, you can override the default message in relative JavaScript file.
1 In the Java EE perspective, expand the directory WebContent > js > dojo > nls from Project Explorer.
2 Choose the language file. In this case, open dojo_ko.js.
3 Find the validation message and rewrite it between double quotation marks.
