This form of authentication uses Base64 encoding and
can expose user names and passwords unless all
connections are over SSL.
102. What is general entity

entity, which is referenced in the DTD. A general
entity can be a parsed entity or an unparsed entity.
103. What is group

traits such as job title or customer profile. Groups
are also associated with a set of roles, and every

An object that identifies an enterprise bean. A client
can serialize the handle and then later deserialize it
to obtain a reference to the enterprise bean.

interface of an entity bean defines create, finder,
and remove methods.
