Struts2 - Text Tag (Data Tags)

In this section, we are going to describe the text tag. The text tag is a generic tag that is used to render a I18n text message. Follow one of the three steps:

1. Keep the message to be displayed in a resource bundle with the same name as the action that it is associated with ie. create a properties file in the same package as your Java class with the same name as your class, but with .properties extension.

2. If the property file does-not work or the message is not found in the resource bundle, then the body of the tag will be used as default message.

3. If there is no body, then the name of the message will be used. Add the following code snippet into the struts.xml file.

struts.xml

<action name="textTag" class="net.struts2.textTag">
   <result>/pages/genericTags/textTag.jsp</result>
</action>

Create an action class as shown below:

textTag.java

package net.struts2;
import com.opensymphony.xwork2.ActionSupport;

public class textTag extends ActionSupport {

  public String execute() throws Exception{
  return SUCCESS;
  }
}

Create a property file in the same package where your Java program file (textTag.java) is saved with the name as package.properties.

package.properties

webname1 = http://www.struts2.net
webname2 = http://www.java.com
webname3 = http://www.newstrack.com

Now create a jsp page to see the working of the text tags.
The first three tags , and uses the package.properties file to display the text message.
The next tag Vinod, Amit, Sushil, ....... uses the body of the tag as a default message.
The last tag does not have access to the package.properties files nor does it have a body so it uses name of the message to display.


textTag.jsp


<%@ taglib prefix="s" uri="/struts-tags" %>

  <s:text name="webname2"></s:text><br>
  <s:text name="webname3"></s:text><br>
  <s:text name="empname">Vinod, Amit, Sushil, .......</s:text><br>
  <s:text name="empname"></s:text>

  </body>

Global Action Forwards and Action Mappings

What is an action forward? A action forward can be used to forward to a jsp or action mapping. There are two different action forwards. The global action forward and the local action forward. You can access a global action forward on each jsp or action class. A local action forward can only be accessed by the assigned action class. What is a action mapping? The action mapping is the heart of struts. It managed all actions between the application and the user. You can define which action will be executed by creating a action mapping. The diagram show you, how the application server manage the request of the index.jsp or a non existing action mapping. In the first step we create a new action mapping. Open the struts-config.xml, you will find it in the folder WebRoot/WEB-INF. Right click in the outline window on action-mapping. Choose Use Case default and Action Type Forward. The Forward Path is the welcome page /jsp/index.jsp In the second step you create a global act...
