Sybase products fully support Java EE

Java 2 Platform Enterprise Edition (EE) is a platform through which you can develop, submit, and manage N-tier applications that are server-centric. The Java EE platform is based on a successful java-based 2 platform and is dedicated to the development of enterprise-class business applications. Its main goal is to standardize the next generation platform for Java computing and extend development on the Java platform to the enterprise domain. Java technology now supports the development, submission, and management of N-tier enterprise applications along with the release of EE. Because Java EE supports the architecture of the enterprise application market, Java EE is very noticeable in enterprise computing. In a compact enterprise solution, Java-EE encompasses a variety of existing java-based technologies to accommodate a diverse computing environment: Java 2 Platform, Java 2 Platform Standard Edition, and now Java 2 Platform Enterprise Edition. Thanks to its overall scalability, Java EE is the preferred platform to cover development, submission, and management. Furthermore, as an open standard, Java EE ensures that the platform based on this standard is open, and that server-side java-based development is competitive, avoiding the limitations of the server platform or shutting out a platform

Enterprise applications are to support the current E-commerce transformation at the forefront of business operations and mission-critical, so the Java Java platform to support a series of core of the java-based API, so as to better adapt to today's business environment. These APIs include:

· Enterprise Java Beans? (EJB?) Version 1.1

· Java Server Pages? Version 1.1

· Servlets Version 2.2

· Java message Service Version 1.0.2

· Java Transaction API 1.1

· Jdbc? 2.0 Client and Server Extensions

· Extensible Markup Language (XML)

· Java Naming and Directory Interface (JNDI) 1.2

These APIs are selected according to the requirements of the partners because they: (1) They provide enterprise-level application development capabilities; (2) They adapt to distributed environments. Because of the above reasons, Java EE platform has been widely adopted and accepted by enterprises all over the world, for enterprise application development, submission and management.

Today's business applications are often distributed or accessible on the web, which requires that the submission environment be scalable, robust, and secure, and more importantly, "Write Once Run Anywhere" (once written everywhere is available), the Java EE is the platform that embodies these features. Because this new platform is trying to prove that the application based on Java EE can run on any vendor's device. For users, the compatibility of the platform is one of the key factors that enterprises have the confidence to implement enterprise application with Java platform.

/sybase Company has pioneered the integration of Java EE with existing products, especially Enterprise Application Server (EAServer), Adaptive Server Enterprise (ASE), and Enterprise Portal (EP) and other products. Through the full support of Java EE, you can make the components in application once written can be run on any Java-compatible products. Using this standard open architecture, users can not only establish an enterprise application optimization model, but also provide maximum scalability for future application submissions. That is, once the component is submitted to the Easerver, it can be accessed by different applications on different platforms as long as they are compatible with the Java EE.

/easerver 3.5 includes the functionality of the component Transaction Server and the functionality of the Dynamic Web page server, providing highly reliable, robust submission capabilities in web and distributed applications. Easerver supports Java EE technology at the core level, including EJB, Java Servlets, Java Server Pages, JNDI, JavaMail, JTA, JDBC 2.0. In addition, Easerver seamlessly supports various types of clients, such as CORBA, XML, HTML, DHTML, C + +, and any ActiveX clients, as well as PowerBuilder. Easerver also provides a single point of integration for heterogeneous backend systems that can extend customer business applications to the Web.

(There are many users using easerver, such as the University of California Online Museum, the middle tier is Easerver, through Sybase jConnect for JDBC connection to the background Sybase ASE database, the entire application in the Java language development, The front end uses a regular web browser to access the MIP site (http://www.mip.berkeley.edu), and by clicking its hyperlinks list you can browse museums, departmental structures, and other resource information in a variety of formats, including images, text, and numbers, Search engines can quickly find the relevant resources according to the subject words.

In the enterprise application, the Los Angeles National Laboratory's logistics Management system also uses the Sybase solution. Its original system is the application of C/s structure developed by PowerBuilder, now the application is web-based, the front-end application is Java applet, the middle layer is Java Servlet, And through the Easerver and the original system PowerBuilder component and the backstage database tightly integrates, has successfully extended the original application to the Web.

Application server will play a very important role in the future application architecture, and Java EE may be the most commonly used standard in the future, Easerver is also widely used in all walks of life application system.
