Retrieving JavaBeans Component Properties

The main way to retrieve JavaBeans component properties is by using the unified EL expressions. Thus, to retrieve a book title, the Duke’s Bookstore application uses the following expression:

${bookDB.bookDetails.title}

Another way to retrieve component properties is to use the jsp:getProperty element. This element converts the value of the property into a String and inserts the value into the response stream:

<jsp:getProperty name="beanName" property="propName"/>

Note that beanName must be the same as that specified for the id attribute in a useBean element, and there must be a getPropName method in the JavaBeans component. Although the preferred approach to getting properties is to use an EL expression, the getProperty element is available if you need to disable expression evaluation.
