Weblogic Offers Industry's First Implementation Of Enterprise Javabean 1.0 Specification

Tengah's Integrated Services Maximize Enterprise JavaBean Capabilities

Read a complete Tengah 3.1 component overview
June 15, 1998 -- San Francisco, CA -- WebLogic® today announced that its TengahTM JavaTM application server complies with the Java-industry standard 1.0 Enterprise JavaBeanTM (EJB) specification. Enterprise JavaBeans make it dramatically easier to develop, deploy, and manage business-critical Java applications. Tengah Release 3.1 is the first product to support Enterprise JavaBeans 1.0---the standard spearheaded by Sun, HP, IBM, Novell, Oracle, Informix, WebLogic, and other companies.

The focus on deploying Java has spread from the client to the server. This shift is because server-side applications are more easily secured, managed, scaled up, and interconnected with existing corporate databases and business systems. With this shift has come demand for a component model that targets the server. Component technologies like JavaBeans and ActiveX revolutionized client development by allowing programmers to assemble graphical applications out of existing components. Enterprise JavaBeans is a component model for server applications. Today, EJB is being used both for new business components and for "wrapping" existing business systems so that they can be easily exported over intranets, extranets, and the Internet.

Enterprise JavaBeans let users take advantage of the rapid application development and rich graphical interfaces of client/server without sacrificing the thin-client manageability and security of the mainframe. EJB accomplishes this by making it very easy to partition an application into user interface and business logic. The user interface can be specified within HTML via a Java servlet, in a Java applet, or in a client application (written in Java, Visual Basic, PowerBuilder, etc.). The business logic components are packaged as Enterprise JavaBeans. EJBs are easily deployed anywhere on the network and reused within other business applications.

"Enterprise JavaBeans make it easy to build network-ready applications," said Paul Ambrose, CTO and founder of WebLogic. "Prior to the advent of EJB, application partitioning was hard. Programmers had to worry about making server objects persistent, finding them over the network, securing them from unwanted access, protecting them from sharing conflicts and failures, managing their lifecycle, and ensuring their scalability and availability. EJB removes these complexities so that the programmer can focus on the business logic."

"Enterprise JavaBeans empower users to succeed with middleware deployments," said Scott Dietzen, VP of marketing for WebLogic. "Traditional middleware is hard to use because it has not been well-integrated with programming languages or tools. What's worse, middleware calls muddle the business logic, complicating application maintenance, portability, and interoperability. With the Java-standard enterprise services, applications can be developed independently of underlying middleware, which makes broad reuse of business logic a reality."

EJB is a critical enabling technology for Java application servers like WebLogic Tengah. Application servers provide the platform for assembling, integrating, deploying, and managing network-enabled applications. Tengah EJB delivers on the promise of reusable business objects that can be easily snapped together and moved from platform to platform.

"The arrival of Enterprise JavaBeans is an important milestone in proving out Java's readiness for business-critical systems," said Anne Thomas, senior consultant at Patricia Seybold Group. "I am impressed that not only has WebLogic gotten their EJB implementation out ahead of the others, but that they have already implemented the optional EJB extensions of automatic persistence, distributed transactions, and entity beans."

"The real power of Tengah is that it combines a robust, scalable EJB implementation with the other essential Java-standard enterprise services," continued Ambrose. "Supporting all of the Enterprise Java standards within a single integrated server means that the Tengah EJB user won't have to buy several technologies a la carte and do custom integration. Tengah is also the first Java application server to offer Java-standard database integration, event management, remote object access, global naming, and servlets for supporting HTML clients. WebLogic's commercial-grade implementations of all of the supporting services is what has enabled us to bring EJB technology to market so quickly."

WebLogic has been a key participant in the development of the EJB specification. EJB 1.0 is the fourth version of the specification that WebLogic has implemented within Tengah. With Tengah 3.1, WebLogic is offering all of the optional EJB extensions including automatic persistence for business objects (entity beans), distributed transactions, and support for the Java Transaction Service (JTS).

"EJB makes it easier for us to deliver highly reliable Java applications," said Ed Freeman, CEO of the Radiance Group, Inc. "Radiance makes healthcare information systems that provide an end-to-end solution for practice management and healthcare delivery. To be competitive in our business, we need to be able to offer very easy-to-use, easy-to-manage, and portable products, and do it all quickly. Java and Tengah fill this bill. Tengah combines the latest Enterprise JavaBean capabilities with the other standard Java services we need. Tengah allows us to focus on our business and not on system infrastructure."

In addition to supporting all of the optional EJB extensions, Tengah's EJB implementation also provides:

  • Rich, graphical management of Enterprise JavaBeans.
  • Strong RSATM-based security.
  • Enterprise scalability through optimizations such as data caching, database connection pooling, and fully multithreaded execution.
  • Global naming via the Java Naming and Directory Interface (JNDI).
  • Integrated support for the other standard Java enterprise services essential for taking advantage of EJB including Java Database Connectivity (JDBC), Remote Method Invocation (RMI), HTTP Servlets, and Java event management.
