JRun

The Fast, Affordable, and Reliable J2EE™ Compatible Application Server

The Fast, Affordable, and Reliable J2EE™ Compatible Application Server Macromedia JRun 4 provides the speed and reliability required to deploy and manage your standards-based Internet applications. Loaded with features for accelerated deployment and powerful scalability, JRun is an elegantly architected, web-services enabled, approachable platform with full Java™ 2 Enterprise Edition (J2EE) compatibility. Currently used in production at over 10,000 companies worldwide, JRun is the proven solution for reducing the time and cost associated with developing and deploying applications.

JRun Key Features

Standards Support

JRun implements the complete J2EE platform specification, including Java Server Pages, Java Servlets, Enterprise JavaBeans, Java Message Services, and other Java and web services APIs

Certified J2EE 1.3 compatible:
JRun 4 is certified J2EE 1.3 compatible, implementing the latest standards support for the complete Java 2 platform APIs

Advanced EJB 2.0 support:
The JRun 4 EJB container has been rearchitected to provide superior support for the new EJB 2.0 features, including local interfaces, message-driven beans, EJB-QL, and container managed persistence (CMP) 2.0

Web services integration:
Building web services in JRun 4 is as simple as editing a deployment descriptor to expose your regular Java classes or Enterprise JavaBeans as web services.

Consuming web services is equally easy:
JRun 4 automatically generates Java proxies for web services based on their WSDL files. JRun has integrated support for open web services protocols such as SOAP, WSDL, and UDDI

Development and Deployment Services

In addition to the core J2EE services, JRun includes features to simplify and speed the development and deployment process. Using the power of the new development and deployment features of JRun, you can deliver your applications faster in a non-stop server environment

Auto deployment:
Deploying an application is as simple as copying an EAR, JAR, WAR, or RAR file to the server directory. JRun automatically senses the new file, deploys it, and makes it available in the target server: No need to restart the server

Hot Modification:
During development, you can hot modify any application component (servlets, JavaServer Pages,™ Enterprise JavaBeans, Java Classes, deployment descriptors). The changes take effect immediately without the need to restart the server

XDoclet integration:
XDoclet is tightly integrated into JRun 4. When modifications are made to the source file, JRun will automatically generate the necessary auxiliary files, such as interfaces and deployment descriptors

EJB development and deployment tool:
The Enterprise Deployment Wizard streamlines developing and deploying Enterprise JavaBeans. With new O/R mapping capabilities for CMP 1.1 and CMP 2.0, you can generate and deploy a fully-functional entity bean in minutes

IDE integration:
JRun 4 integrates with industry-leading development tools, such as JBuilder, IntelliJ, Forte and WebGain

Presentation Services

Macromedia Flash MX remoting services:
With the built-in Macromedia Flash MX player connectivity, it’s easy to provide your J2EE applications with a high impact user interface. Macromedia Flash remoting allows user interfaces built in Macromedia Flash to connect to EJBs, Java classes, and MBeans in a simple, fast and secure manner

JRun server tags technology:
JRun Server Tags (JST) allow you to write custom tags using JavaServer Pages instead of the more complex custom tag handler. Custom tag development is faster and more approachable

Built-in web server:
JRun ships with a built-in, high-performance HTTP server. Additionally, JRun provides connectors for support of other leading HTTP servers

High performance web server connectors:
High performance and clustering-enabled web server connectors also allow you to use JRun with all the major web servers including Apache, Microsoft IIS, Netscape Enterprise Server, IPlanet, and Zeus

Data Access Services

Bundled type IV JDBC drivers:
JRun 4 comes with high performance JDBC drivers for the leading databases: Oracle®, Microsoft® SQL Server, Sybase, DB2, and Informix

Java API for XML parsing (JAXP):
JRun integrates a JAXP-compliant XML parser and an eXtensible Stylesheet Language Transformation (XSLT) engine

Open and Extensible Architecture

Built on an elegant JMX service-oriented architecture with a small footprint, the JRun Server is easily customized, extended, or embedded to meet your unique business requirements.

Service oriented architecture:
JRun services–EJB container, Web container, logging, and others—are implemented as MBeans plugged into the JMX based JRun kernel. This plug-in architecture provides a highly customizable and easily extensible deployment platform.

Java Message Service (JMS):
JRun 4 includes a durable and transactable JMS 1.02b-compliant provider that supports both point-to-point and publish/subscribe synchronous and asynchronous messaging. JRun 4 can also be used in conjunction with an external JMS provider, such as SonicMQ

Small Disk Footprint:
JRun is a lean and efficient application server that does not carry the excess overhead that goes along with legacy technology. JRun lets you control the components you install and activate to optimize memory resources at runtime.

Performance and Scalability

Superior performance and breakthrough Jini™ technology-based server cluster management capabilities allow your applications to scale in a reliable and highly optimized runtime environment

Superior servlet and JSP performance:
The elegant and small footprint architecture in JRun is optimized for performance. Since its introduction in 1997, JRun is recognized as the fastest web container in the application server market

Advanced Jini technology-based server clustering:
JRun 4 provides enterprise-class server clustering, allowing load balancing and automatic failover at all levels–web server, web connector and component. JRun servers use Jini technology to dynamically locate their peers in the cluster, eliminating the risk inherent to a single point of failure

Performance tracing:
Instrumentation allows you to identify and resolve performance bottlenecks in your code by tracing and timing each method invocation in your application. Instrumentation is supported for JSPs, servlets, and EJBs

Application and Server Management

JRun management console:
The redesigned, JMX-enabled JRun Management Console (JMC) provides an easy-to-use, web-based graphical user interface to manage your local and remote JRun servers. Using the JMC, you easily create servers, define clusters, manage applications, and implement JAAS-based security

Point-and-Click server cluster administration:
Installing and managing a cluster of JRun servers is straightforward. Using the JRun Management Console (JMC), you define and administer a cluster in a point-and-click environment. JRun also simplifies the deployment of applications into a clustered environment. The JRun Management Console (JMC) provides a one-step deployment option to all the servers in the cluster
