bean
A component architecture for the Java
programming language, developed initially by Sun, but now
available from several other vendors. JavaBeans components
are called "beans".
JavaBeans allows developers to create reusable software
components that can then be assembled together using visual
application builder tools including Sybase's PowerJ,
Borland's JBuilder, IBM's Visual Age for Java,
SunSoft's Java Workshop and Symantec's Visual Cafe.
JavaBeans support Introspection (a builder tool can analyze
how a Bean works), Customisation (developers can customise the
appearance and behaviour of a Bean), Events (Beans can
communicate), Properties (developers can customise and program
with Beans(?)) and Persistence (customised Beans can be stored
and reused).

EJB
(EJB) A server-side
component architecture for writing reusable business logic
and portable enterprise applications. EJB is the basis of
Sun's Java 2 Platform, Enterprise Edition (J2EE).
Enterprise JavaBean components are written entirely in Java
and run on any EJB compliant server. They are {operating
system}, platform, and middleware independent, preventing
vendor lock-in.
EJB servers provide system-level services (the "plumbing")
such as transactions, security, threading, and
persistence.
The EJB architecture is inherently transactional,
distributed, multi-tier, scalable, secure, and {wire
protocol} neutral - any protocol can be used: IIOP,
JRMP, HTTP, DCOM etc. EJB 1.1 requires RMI for
communication with components. EJB 2.0 is expected to require
support for RMI/IIOP.
EJB applications can serve assorted clients: browsers, Java,
ActiveX, CORBA etc. EJB can be used to wrap {legacy
systems}.
EJB 1.1 was released in December 1999. EJB 2.0 is in
development.
Sun claims broad industry adoption. 30 vendors are shipping
server products implementing EJB. Supporting vendors include
IBM, Fujitsu, Sybase, Borland, Oracle, and
Symantec.
An alternative is Microsoft's MTS ({Microsoft Transaction
Server}).
