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.
