WebLogic Server and the J2EE Platform
interface an object presents to clients. IDL is completely independent of the language
used to implement the objects and clients. An IDL compiler translates the IDL source
statement to the appropriate language.
NonStop CORBA is the HP implementation of the Object Management Group (OMG)
CORBA specification. NonStop CORBA offers the advantages of distributed object
computing combined with the fundamental availability, scalability, data integrity, and
manageability of the HP NonStop platform and the TS/MP and TMF middleware.
WebLogic Server and the J2EE Platform
BEA WebLogic Server on HP NonStop servers is an application server that provides a
framework for building and managing applications. As you have seen in Sections 1 and
2, a zero latency enterprise depends on comprehensive and efficient data and
application integration. Zero latency operations require a unifying architecture for
integrating, synchronizing, routing, caching, and performing database transactions in
real time. WebLogic Server provides an easy and efficient way to bring together new
and existing applications that provide all the services required by a zero latency
enterprise.
WebLogic Server has features that provide for fault tolerance, load balancing, and
simplified application management while taking advantage of the reliability and
performance of the NonStop server. WebLogic Server, as implemented on the NonStop
server, also provides all the benefits of a fault tolerant transaction manager (TMF) and
the massively scalable relational database system (SQL/MX).
WebLogic Server is built on the Sun Microsystems Java 2, Enterprise Edition (J2EE)
application server platform, which enables developers to take full advantage of Java
technology. This combination of WebLogic Server and J2EE forms the application
server environment that is the most widely used in today’s HP ZLE systems.
WebLogic Server simplifies the development, deployment, integration, and
management of applications by surrounding the latest J2EE and Web services
standards with easy-to-use development and administration tools and powerful
clustering, security, integration, and management features. The built-in services of
WebLogic Server relieve developers of the need to create these services on their own.
Figure 3-15 on page 3-23 illustrates WebLogic Server and its role as an application
server environment within the ZLE framework. As the figure shows, WebLogic Server
provides an environment for applications and the essential services to support the
applications, including load balancing, fault tolerance, transaction management, and
messaging.
