BEA WebLogic Express 9.1 is a powerful, cost-effective Servlet
engine that gets you up and running on the WebLogic™ product line in
record time. Use WebLogic Express to quickly develop and launch dynamic Web
sites and basic Web applications that gives you the most reliable, production-ready
deployment on the market.
Because WebLogic Express
has the same code base as WebLogic Server, most information on this page also
applies to WebLogic Server, and many documentation links refer to WebLogic
Server documentation pages.
WebLogic Express is a good fit for projects
that use Servlets, Java Server Pages (JSPs), and Java applications
using Java classes, Remote Method Invocation (RMI), and Java Database
Connectivity (JDBC). WebLogic Express does not support Enterprise
Java Beans, Java Messaging Service, J2EE Connector Architecture,
Web services, and other features targeted at enterprise-level
applications. It is a suitable alternative to using an Open Source
Servlet Engine. Read the white paper "Selecting the Right Java Servlet Engine for Your Environment" for a detailed discussion comparing
WebLogic Express 8.1 with the Open Source alternatives.
When to Upgrade
WebLogic Express to WebLogic Server
Upgrade from WebLogic Express to WebLogic
Server if you need to repartition your layers to create a separate
EJB layer for your business logic, to meet certain business needs, or to
manage complex architecture. You should upgrade to WebLogic
Server if you need to integrate applications that are supported
by J2EE Resource Adapters. Also upgrade to WebLogic
Server if you need a messaging infrastructure (Java Messaging
Service) for your application.
