<% // these will be used in formatting the message for test2 java.util.Date dateArg = new java.util.Date(); java.lang.Float numberArg = new java.lang.Float("123.45"); %> The current locale is <%= pageContext.getResponse().getLocale() %>. Items show in italics are localized.

The message tag with no body displays the value provided for the provided key in the bundle named by the localize tag.

<i18n:message key="test1"/>

The message tag with nested messageArg tags make use of the java.text.MessageFormat class.

  <i18n:message key="test2">
    <i18n:messageArg value="<%= dateArg %>"/>
    <i18n:messageArg value="<%= numberArg %>"/>
  </i18n:message>

The message tag with a defined body provides a default in case a particular locale doesn't have the key defined. This is also useful to

provide some text during development
allow the JSP's to be laid out using standard html editing tools
provide "if not" JSP processing

  <i18n:message key="no.such.key">
     This text would be displayed if a language neglected to
     define a value for no.such.key.  Arguments are supported {0,date,short}
    <i18n:messageArg value="<%= dateArg %>"/>
  </i18n:message>

This text would be displayed if a language neglected to define a value for no.such.key. Arguments are supported {0,date,short}
