Sun Java System Application Server 9.1 Update 1 |
The Sun Java System Application Server 9.1 Update 1 provides a Java EE compatible server for the development and deployment of Java EE applications and Java Web Services. Key features include scalable transaction management, container-managed persistence runtime, performant web services, clustering, high availability, security, and integration capabilities.
This page contains the following topics:
Java EE 5 platform support: Sun Java System Application Server 9.1 complies fully with the latest Java EE 5 specification to deliver one of the best application runtimes for next-generation enterprise applications and web services. Application Server 9.1 implements and extends the following Java EE standards:
Web Services Interoperability Technologies (WSIT) Support
Sun is working closely with Microsoft to ensure interoperability of Web services enterprise technologies such as message optimization, reliable messaging, and security. The initial release of WSIT
is a product of this joint effort. WSIT is an implementation of a number of open web services specifications to support enterprise features. In addition to message optimization, reliable messaging, and security, WSIT includes a bootstrapping and configuration technology. Starting with the
core XML support currently built into the Java platform, WSIT uses or extends existing features and adds new support for interoperable web services, including:
Java Business Integration (JBI) Support
JBI extends Java EE with business integration Service Provider Interfaces (SPI). These SPI enable developers to create or implement a Java business integration environment for specifications such as WSCI, PBEL4WS and
the W3C Choreography Working Group. A JBI implementation is installed directly by the Application Server installer, mostly in the AS_HOME/jbi
directory. This directory contains all common JAR files and system components for the JBI including a lifecycle
module that
starts the JBI framework in the Application Server JVM.
In-Memory Replication Support
In-memory replication on other servers provides lightweight storage of session state data without the need to obtain a separate database, such as HADB. This type of replication
uses memory on other servers for high availability storage of HTTP session and stateful session bean data. Clustered server instances replicate session state in a ring of topology. Each backup instance stores the replicated data in memory. Replication of session state data in memory on other
servers enables sessions to be distributed. The use of in-memory replication requires the Group Management Service (GMS) to be enabled.
Usage Profiles Support
Every administrative domain is associated with a usage profile which identifies the capabilities of
that domain. Application Server 9.1 provides the following profiles:
Load Balancing Enhancements
Several enhancements have been added to the load balancing plugin including:
weight
has been added to the instance Loadbalancer.xml
file. This option enables the load balancer plugin to route requests according to the weight. For example, for every 500 requests, 100 will go to instance1
and 400 would go to instance2
. The default weight is 100. The weight is assigned to each instance from the Administration Console or command-line. In addition, the server domain.xml
file identifies an attribute for every instance indicating the weight. loadbalancer.h
, which is placed in appserv_install_dir/lir/install/templates/
. loadbalancer.xml
file be manually copied to the particular server's config
directory. Application Server 9.1 includes push automations for performing such copies between
the Web Server and the Application Server. The load balancer itself is configured in the server's domain.xml
file.Open Source and GlassFish Community
In June 2005, Sun launched the GlassFish community with the goal of developing a free, open source, commercial-grade application server that implements the newest
features of the Java EE 5 platform and related enterprise technologies. Application Server 9.1 is based on the source code developed by Sun engineers and the GlassFish community.
Feedback Submittal Form: Use the Java EE SDK Feedback Submittal Form to submit feedback on this product.
Glassfish Community: Application Server is developed through the Glassfish open source project and community. The GlassFish community is building a free, open source application server which implements the newest features in the Java EE 5 platform.
Java Enteprise Community: Part of java.net, the Java Enteprise Community is centered around Java EE applications, components, and tools.
Sun Technology Forums: The Sun Developer Forums are interactive message boards for sharing knowledge and questions about technologies and programming techniques. Use the Application & Integration Servers forum for discussions related to the Application Server.
Sun Software Support Service: Sun Software Support Service Standard contracts are available for purchase.
Sun Developer Network: For further help and to keep on top of the latest developments, join the Sun Developer Network.
BigAdmin System Administrator Resources and Community: Join this System Administration Portal to learn more about the Sun Java System Application Server Platform Suite which includes the Application Server.
Release Notes and Product Documentation: The Release Notes, Installation Guide, and other product documentation are available in the Sun Java System Application Server 9.1 Update 1 collection on the docs.sun.comSM site.
