Property Tag (Data Tag) Example

     

In this section, we are going to describe the property tag. The property tag is a generic tag that is used to get the property of a value, which will default to the top of the stack if none is specified.

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

struts.xml

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

Create an action class as shown: 

propertyTag.java

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

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

Create a bean class "companyName" as shown: 

companyName.java

package net.roseindia;

public class companyName {
  
  private String name;

  public void setName(String name){
  this.name =name ;
  }

  public String getName(){
  return name;
  }
}

Create a jsp using the tags.

<s:property value="%{name}" /> it prints the result of myBean's getMyBeanProperty() method.

<s:property value="name" default="Default Value" /> it prints the result of companyName's getName() method and if it is null, print 'a default value' instead.

propertyTag.jsp

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

<html>
  <head>
  <title>Property Tag (Data TagExample</title>
  </head>
  <body>
  <h1><span style="background-color: #FFFFcc">Property Tag 
    (
Data TagsExample!</span></h1>
  <!-- Example to pick the value through bean class -->
  <s:bean name="net.roseindia.companyName" id="uid">
  <s:param name="name">RoseIndia</s:param> 
  <s:property value="%{name}" /><br>
  </s:bean>
  <!-- Default value -->
  <s:property value="name" default="Default Value" />
  </body>
</html>

Output of the propertyTag.jsp:
