Hi All

I want to pass, dynamic value to the annotation........

I am using @XmlElement annotation there are two attribute in this annotation which I required ,type and name

@XmlElement(type=anyClassName.class, name = "anyValue")

Problem is this I don't know the class name because ,It comes at run time ,Is there any way to pass the information to annotation at runtime like this ,If there is any solution It would be very helpful to me.

class TheClass{

@XmlElement(type=anyClassName.class, name = "anyValue")

Annotations can only be set at compile time; that also why their values can only be compile time constants. The only thing you can do with them at runtime is reading them.

In this case I would say that an interface with getter and setter methods for both class and name would be more appropriate.
