• Reflective Middleware helps TOWARDS adaptation
• Open up the internal implementation
• Look middleware as Grey-box
• Provide reflection and adaptation mechanism

Architecture based Reflective Middleware
By manipulating upon RSA through reflective APIs
of middleware, programmer can dynamically change
the application behaviours.
