Action Tag

The action tag is a generic tag that is used to call actions directly from a JSP page by specifying the action name and an optional namespace. The body content of the tag is used to render the results from the Action. Any result processor defined for this action in struts.xml will be ignored, unless the executeResult parameter is specified.

Add the following code snippet into the struts.xml file.

struts.xml

<action name="actionTag" class="net.roseindia.actionTag">
<result name="success">/pages/genericTags/success.jsp</result>
</action>

Create an action class as shown below:

actionTag.java

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

public class actionTag extends ActionSupport {
  public String execute() throws Exception{
  return SUCCESS;
  }
}

Now create a jsp page using <s:action> tag as shown in the success.jsp page. The action tag is used to call actions directly from a JSP page by specifying the action name and an optional namespace.

success.jsp

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

<html>
  <head>
  <title>Action Tag Example!</title>
  </head>
  <body>
  <h1><span style="background-color: #FFFFcc">Action Tag 
  (Data Tags) Example!</span></h1>
  <s:action name="success">
  <b><i>The action tag will execute the result and include 
  it in this page.</i></b></div>
  </s:action>
  </body>
</html>

Output of the success.jsp
