Gets the value of a Bean property so that you can display it in a result page.
<jsp:getProperty name="beanInstanceName" property="propertyName" />
<jsp:useBean id="calendar" scope="page" class="employee.Calendar" />
<h2>
Calendar of <jsp:getProperty name="calendar" property="username" />
</h2>
The <jsp:getProperty> element gets a Bean property value using the property's getter methods and displays the property value in a JSP page. You must create or locate a Bean with
<jsp:useBean> before you use <jsp:getProperty>.
The <jsp:getProperty> element has a few limitations you should be aware of:
<jsp:getProperty> to retrieve the values of an indexed property.
<jsp:getProperty> with JavaBeans components, but not with enterprise beans. As alternatives, you can write a JSP page that retrieves values from a Bean that in turn retrieves values from an enterprise bean, or you can write a custom tag that retrieves values from an enterprise bean directly.
The name of an object (usually an instance of a Bean) as declared in a <jsp:useBean> element.
The name of the Bean property whose value you want to display. The property is declared as a variable in a Bean and must have a corresponding getter method (for more information on declaring variables and writing getter methods in Beans, see the JavaBeans API Specification).
<jsp:getProperty> to retrieve a property value that is null, a NullPointerException is thrown. However, if you use a scriptlet or expression to retrieve the value, the string null is displayed in the browser;
see Scriptlet or Expression for more information.
