initialization information to the Servlet.
iv.Server calls the init() method of each Servlet instance.
v.The server constructs aServletRequest or HttpservletRequest object
from the data included in the client’s request.
vi.The server calls the servlet’s service() method passing the objects
constructed
vii.Servlet’s service() method processes the request and returns output
to client
viii.Servlet waits until next request is received.

What is Bean Property? List and explain Java beans properties
SCHEME OF
EVALUATION
A bean property is a named attribute of a bean that can affect its
behavior or appearance. Examples of bean properties include color,
label, font, display size etc.
The JavaBeans specification defines the following types of bean
properties.
i.Simple: a bean property with a single value whose changes are
independent of changes in any other property.
ii.Indexed: a bean property that support a range of values instead of a
single value.
iii.Bound: a bean property for which a change to the property results in
a notification being sent to some other bean.
iv.Constraint: a bean property for which a change top the property
results in validation by another bean. The other bean may reject the
change if it is not appropriate.
Bean properties can also be classified as follows
*Writable : A bean property that can be changed
*Standard
*Expert
*Preferred.
*Read only: A bean property that cannot be changed
*Hidden : a bean property that can be changed. However, these

QUESTION_TEXT
What do you mean by CORBA? Explain its architecture?
SCHEME OF
EVALUATION
The Common Object Request Broker Architecture is a standard
architecture for distributed object systems.
The services that an object provides are given by its interface. Interfaces
are defined in OMG’s interface definition language (IDL).
The figure graphically depicts a request. A client holds an object
reference to a distributed object. The object reference is typed by an
interface. In the figure, the object reference is typed by the Rabbit
interface. The Object Request Broker, or ORB, delivers the request to
the object and returns any results to the client. In the figure, a jump
request returns an object reference typed by the AnotherObject Interface.
The ORB is the distributed service that implements the request to the
remote object.
The ORB implements location transparency.
The ORB implements programming language independence for the
request. The client using the request can be written in a different
programming language from the implementation of the CORBA object.
