What is session bean ?
An enterprise bean that is created by a client and that usually exists
only for the duration of a single client-server session. A session bean performs
operations, such as calculations or database access, for the client. Although a
session bean can be transactional, it is not recoverable should a system crash
occur. Session bean objects either can be stateless or can maintain
conversational state across methods and transactions. If a session bean
maintains state, then the EJB container manages this state if the object must be
removed from memory. However, the session bean object itself must manage its own persistent data.
What is SGML ?
Standard Generalized Markup Language. The parent of both HTML and XML.

time as with a JDBC driver.
What is SSL ?
Secure Socket Layer. A security protocol that provides privacy over the
Internet. The protocol allows client-server applications to communicate
in a way that cannot be eavesdropped upon or tampered with. Servers are
always authenticated, and clients are optionally authenticated.
What is stateful session bean ?

What is tag ?
In XML documents, a piece of text that describes a unit of data or an
