JavaBean property values can themselves be JavaBeans with their own property values. You can reference nested property values in JSPs with the following syntax:[.nested-property]...

When you reference a property in a JSP, you can also reference a property of that property, with multiple levels of indirection.

For example, the JavaBean PersonManager has the property currentPerson. The value of this property is an instance of a Person class object which has an age property. A JSP can reference the age of the current person as follows:

<dsp:getvalueof value="/samples/PersonManager" var=pMgr></dsp:getvalueof>
<c:out value="${pMgr.currentPerson.age}"
