WebLogic Unveils Industry's First Pure-Java Application Server

Tengah Radically Simplifies Building, Deploying and Managing Distributed Java Applications

November 3, 1997 -- San Francisco, Calif. -- WebLogic Inc., a pioneering developer of database integration technology for Java, today unveiled TengahTM, the industry's first comprehensive Java application server. Tengah uniquely makes building, deploying and managing commercial-grade, distributed Java applications easy -- letting IT focus on business logic, and not infrastructure.

Currently, corporations and application vendors often spend more than 50 percent of their development resources creating infrastructure. With Tengah, corporations can quickly deploy and manage Java applications across heterogeneous Java platforms and databases, and securely scale them to support thousands of clients across intranets, extranets and the Internet.

Tengah, written entirely in Java, delivers a breakthrough suite of integrated services that address a comprehensive range of IT requirements including distributed components, distributed objects, event management, database connectivity, global directory support and Web integration. Tengah application services are compliant with Java industry standards, and thus, do not require a user commitment to proprietary programming interfaces.

"IT demands a comprehensive set of standards-based services for building networked applications that meet the needs of today's increasingly global, real-time and interrelated business processes," said Paul Ambrose, WebLogic co-founder and Chief Technology Officer. "WebLogic is the only vendor to address the broad spectrum of these application-level services, and do so in a single, well-integrated solution. Tengah enables corporations to leverage the power and ease-of-use afforded by Java across the network."

"For Java to make it in enterprise applications, it has to be practical for server-side logic, as well as for client-side applets," said John R. Rymer, president of Upstream Consulting in Emeryville, Calif. "Tengah enables this key shift in Java, making it possible for mere mortals to build and run distributed applications in Java."

Tengah provides the flexibility to run business logic where companies need it, without the usual complexity of multitier computing. For example, tasks that are compute-intensive or highly secure can be run on the server while those that are highly interactive can be run in the browser. Tengah provides a seamless integration between the client- and server-side logic and even permits dynamic migration of tasks.

Tengah Features

With Tengah, Java applications can be partitioned using powerful Java-native mechanisms like JavaBeans, Remote Method Invocation (RMI), and distributed events. Tengah is pure Java and compatible with leading Java Integrated Development Environments (IDEs). Tengah includes WebLogic's industry leading database integration solution for Java based on the JavaSoft-standard JDBC.

Tengah supports open protocols like HTTP and CORBA IIOP, and offers application security through optional Secured Socket Layer (SSL) support. Protocol tunneling and request forwarding allow secure dispatching to servers behind corporate firewalls. Integration with enterprise directories is provided via the Java Naming and Directory Interface (JNDI), which supports the internet-standard Lightweight Directory Access Protocol (LDAP). In addition, Tengah is the first Java application server to offer sophisticated application monitoring and management, allowing visibility into the state of user-defined and system components.

The Tengah suite of integrated application services includes the following:

  • Enterprise JavaBeans (based on 0.5 draft of the JavaSoft specification), which makes it very easy to encapsulate server-side business logic as secure, transactional components;

  • RMI, which allows any remote object's methods to be exported to clients or other servers;

  • JDBC, which allows high-performance, multitier access to Oracle, Microsoft SQL Server, Sybase, and Informix (available in Q4 '97) based on WebLogic's native database drivers rather than ODBC (although, as an open solution, Tengah can be used with any other JDBC-compliant driver);

  • Distributed Events, which provides for the remote publication and subscription to events with server-side, content-based filtering and true "server push";

  • Distributed JavaBeans, which enable transforming any off-the-shelf JavaBean into client/server components;

  • and Servlet support.

Practical Details

Tengah is shipping now. Development license fees start at $1,995 per seat, and production licensing fees begin at $9,995. Tengah supports any 1.0.2 or 1.1-based Java client and runs on Solaris, NT, AIX, Digital, HP, NetWare, SGI servers. Tengah/JDBC remains $4,995.

Tengah is available to Independent Software Vendors (ISVs), OEMs and corporate application developers, and can be downloaded from the WebLogic website.
