dsp:valueof
can specify a default value to display by embedding it between the open and close tags. This value displays only if the component property or EL variable is empty, or undefined/null.
If no default value is required, you can use this simplified syntax:
<dsp:valueof dynamic-value-spec />
For example, you can access properties of the Student_01
component as follows:
Name: <dsp:valueof bean="Student_01.name"/><p>
Age: <dsp:valueof bean="Student_01.age"/><p>
