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.
