Param.UnnamedParametric

public class Text
extends ContextBean
implements Param.UnnamedParametric

Render a I18n text message.

The message must be in a resource bundle with the same name as the action that it is associated with. In practice this means that you should create a properties file in the same package as your Java class with the same name as your class, but with .properties extension.

If the named message is not found in a property file, then the body of the tag will be used as default message. If no body is used, then the stack will be searched, and if a value is returned, it will written to the output. If no value is found on the stack, the key of the message will be written out.

• name* (String) - the i18n message key

Example:

 

 Accessing messages from a given bundle (the i18n Shop example bundle in the first example) and using bundle defined through the framework in the second example.


 
 

 

 <!-- First Example -->
 <s:i18n name="struts.action.test.i18n.Shop">
     <s:text name="main.title"/>
 </s:i18n>

 <!-- Second Example -->
 <s:text name="main.title" />

 <!-- Third Examlpe -->
 <s:text name="i18n.label.greetings">
    <s:param >Mr Smith</s:param>
 </s:text>

 
 

 

 <-- Fourth Example -->
 <s:text name="some.key" />

 <-- Fifth Example -->
 <s:text name="some.invalid.key" >
    The Default Message That Will Be Displayed
 </s:text>
