JSP jsp:setProperty Tag
The setProperty tag is used to store data in JavaBeans instances. The syntax of setProperty tag is:
<jsp:setProperty name="beanName" property="*">
<!-- or -->
<jsp:setProperty name="beanName" property="propertyName">
<!-- or -->
<jsp:setProperty name="beanName" property="propertyName" param="parameterName">
<!-- or -->
<jsp:setProperty name="beanName" property="propertyName" value="propertyValue">
The name attribute specifies the name of javaBean instances. This must match the id attribute specified in the jsp:useBean tag. The property attribute specifies which property of the bean to access.
Example of setProperty with Java Bean
Following is our Java class.
PersonBean.java
import java.io.Serializable;
public class PersonBean implements Serializable
{
private String name;
public PersonBean()
{
this.name="";
}
public void setName(String name)
{
this.name = name;
}
public String getName()
{
return name;
}
}
hello.jsp
<html>
<head>
<title>Welcome Page</title>
</head>
<jsp:useBean id="person" class="PersonBean" scope="request" />
<jsp:setProperty name="person" property="name" value="Viraj" />
<body>
Name of Person is : <jsp:getProperty name="person" property="name" />
</body>
</html>
Output will be → Name of Person is : Viraj
Similarly we can have a very complex Java Bean as well, with many properties. We can easily get and set all the properties using the jsp:useBean, jsp:setProperty, jsp:getProperty.
