FOR IMMEDIATE RELEASE

WebLogic Offers First Commercial JavaTM Application Server to Implement Updated Enterprise JavaBeanTM Specification

Tengah's Integrated Services Maximize Enterprise JavaBean Capabilities

March 10, 1998 -- San Francisco, CA.  WebLogic Inc., a pioneering developer of Java technologies, today announced its TengahTM Java application server is fully compliant with JavaSoft's 0.8 Enterprise JavaBeanTM (EJB) specification. Enterprise JavaBeans, a server-side component model for transaction processing in Java, makes it dramatically easier to develop, deploy, and manage business-critical applications. Tengah Version 3.0.1, which is now generally available, is the first Java application server to support EJB.

Enterprise JavaBeans transparently provide integrity and security for multitier Java applications. EJB technology is critical because it "hides" lower-level programming details such as distributed transaction management, persistence, multithreading, resource pooling, and naming. With EJB, Java developers focus on business logic. And business applications based on Enterprise JavaBeans are extremely portable, since an Enterprise JavaBean can run on any EJB server, even if that server uses different transaction and security mechanisms.

"The real power of Tengah is that it combines EJB with all of the other Java-standard services you need for business-critical applications," said Paul Ambrose, WebLogic Founder and CTO. "Tengah was also the first to market with database integration, event management, remote object access, and directory service integration. Supporting all of the Enterprise Java standards within a single integrated server is uniquely powerful. Without Tengah, the EJB user has to buy several technologies a la carte and do custom integration."

"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 EJB optional extensions of automatic persistence, distributed transactions, and entity beans."

With Tengah 3.0.2, WebLogic is offering all of the optional EJB extensions including:

  • Entity beans -- Entity beans extend EJB for "conversational" transactions in which the client and server communicate multiple times before a unit of work (such as an order) is confirmed.
     
  • Distributed transactions -- Multiple servers and Enterprise JavaBeans may be involved in a single atomic transaction.
     
  • Automatic Persistence -- Enterprise JavaBeans may be configured to transparently maintain any internal state persistently using a database or file system.
     
  • Java Transaction Service (JTS) -- Tengah optionally offers JTS for applications needing greater control over transactions. JTS, for example, allows a client to initiate a transaction that then spreads to multiple servers.

"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 is well-differentiated by providing:

  • Transparent replication for automatic load-balancing and failover.
     
  • Strong RSA-based security.
     
  • Rich, graphical management of Enterprise JavaBeans.
     
  • Comprehensive support for the Java Enterprise Standards needed to fully leverage EJB, including Java Database Connection (JDBC), Remote Method Invocation (RMI), Servlets (for HTML), and the Java Naming and Directory Interface (JNDI).
     
  • Full Java types as arguments to Enterprise JavaBeans. (Other implementations will restrict the EJB developer by not allowing them to pass Java business objects like Trade or Account as parameters to an Enterprise JavaBean. With EJB products other than Tengah, the EJB developer will have to convert each of their Java object parameters into more basic structures.)
