ISVs need the J2EE platform because it gives them a blueprint for providing a complete enterprise computing solution on the Java platform.

Complete Web services support. The J2EE platform provides a framework for developing and deploying web services on the Java platform. The Java API for XML-based RPC (JAX-RPC) enables Java technology developers to develop SOAP based interoperable and portable web services. Developers use the standard JAX-RPC programming model to develop SOAP based web service clients and endpoints. A web service endpoint is described using a Web Services Description Language (WSDL) document.

The primary technologies in the J2EE platform are: Java API for XML-Based RPC (JAX-RPC), JavaServer Pages, Java Servlets, Enterprise JavaBeans components, J2EE Connector Architecture, J2EE Management Model, J2EE Deployment API, Java Management Extensions (JMX), J2EE Authorization Contract for Containers, Java API for XML Registries (JAXR), Java Message Service (JMS), Java Naming and Directory Interface (JNDI), Java Transaction API (JTA), CORBA, and JDBC data access API. What's new in the J2EE 1.

For more information about the J2EE platform and how to get the specification, see http://java.sun.com/j2ee/. The most effective way to learn about the J2EE platform and what's new in the J2EE 1.4 platform is to get hands on experience with the APIs by using the J2EE 1.4 SDK. The J2EE 1.4 SDK provides a J2EE 1.4 compatible application server as the foundation to develop and deploy Web services enabled, multi-tier enterprise applications. You can download the J2EE 1.4 SDK from http://java.sun.

Yes. The J2EE Compatibility Test Suite (CTS) is available for the J2EE platform. The J2EE CTS contains over 5,000 tests for J2EE 1.4 and will contain more for later versions. This test suite tests compatibility by performing specific application functions and checking results. For example, to test the JDBC call to insert a row in a database, an EJB component makes a call to insert a row and then a call is made to check that the row was inserted.

J2EE applications that are written to the J2EE 1.3 specification will run in a J2EE 1.4 implementation. Backwards compatibility is a requirement of the specification.

The Java 2 Platform, Enterprise Edition (J2EE) is a set of coordinated specifications and practices that together enable solutions for developing, deploying, and managing multi-tier server-centric applications. Building on the Java 2 Platform, Standard Edition (J2SE), the J2EE platform adds the capabilities necessary to provide a complete, stable, secure, and fast Java platform to the enterprise level.

The best places to start are the Java Tutorial for learning about Java programming, and the J2EE Tutorial for getting acquainted with the different J2EE technologies. The Java Enterprise BluePrints and the Java Pet Store demo application assume that developers are already familiar with the concepts of the J2EE Tutorial. Once you have completed the J2EE Tutorial, you should read our guidelines, and then download our free source code to start building J2EE applications.

The J2EE Tutorial for the Sun ONE Platform is a programmer's guide for the J2EE platform. It relies on Sun ONE software (Studio 4 update 1, Enterprise Edition for Java and Sun ONE Application Server 7, Platform or Standard Edition) to develop and deploy J2EE applications.

Note: If you download the tutorial, feel free to make it available locally at your site. Please do not publicly mirror it to the Web!. See the next question and answer to find out why. Anyone is permitted have a copy of the online tutorial as long as it's visible only within their own institution (university, business, or whatever) and no one is profiting from the tutorial's distribution.

The tutorial reflects J2EE version 1.3, with additional Web services components provided by the Sun ONE platform.

MS Access will slow down as the size of the DB increases and is best suited for smaller systems with limited or no need to keep an audit trail. There are no hard and fast rules, but the quantity and the number of users, number of instruments and the keeping of audit trail records influence rate the of records generated. Consult your QA representative for direction on the use of MS Access in a validated system. Least expensive ProCalV5 product initial cost.

A J2EE licensee has signed a commercial distribution license for J2EE. That means the licensee has the compatibility tests and has made a commitment to compatibility. It does not mean the licensees products are necessarily compatible yet. Look for the J2EE brand which signifies that the specific branded product has passed the Compatibility Test Suite (CTS) and is compatible.

JavaServer Pages and Java Servlets are the web presentation layer in the Java 2 Platform, Enterprise Edition Platform. Sun adapts and integrates the Tomcat code base into the J2EE SDK, which is available under separate licensing.

The Java 2 SDK, Enterprise Edition 1.4 (J2EE 1.4 SDK) is a complete package for developing and deploying J2EE 1.4 applications. The J2EE 1.4 SDK contains the Sun Java System Application Server Platform Edition 8, the J2SE 1.4.2 SDK, J2EE 1.4 platform API documentation, and a slew of samples to help developers learn about the J2EE platform and technologies and prototype J2EE applications. The J2EE 1.4 SDK is for both development and deployment.

J2EE is an environment for developing and deploying enterprise applications. The J2EE platform consists of a set of services, application programming interfaces (APIs), and protocols that provide the functionality for developing multi tiered, and web-based applications.

Visual Studio 2005 Team System enables partners and customers to extend Team System with their own internal or commercial tools and process frameworks. As the platform on which Team System is built, Team Foundation Core Services enable third parties to extend Team System and to share reporting, eventing, groups and permissions, linking, administration and navigation capabilities.

Yes! It works perfectly on Windows and Mac OSX. However, Linux is not fully supported yet, although some customers have successfully ported it to Linux with a minimum of changes. Please check the Linux section of the Framework Forums. You bet! I've got special code in the Framework to make sure that data is written and read to/from the correct shared location so that it works for any users logged onto the Vista PC.

Business Interactif takes in charge the whole set of needs an online shop requires in its desire to internationally growth, with an optimisation of costs' structure:

JSP: It is possible to use AspectJ to affect code in JSPs by precompiling them into Java sources and compiling these with ajc. This can be used, e.g., to customize displays by turning on and off custom JSP taglibs. The mapping from a given jsp source to java package and class name is not standardized, which means doing this imposes dependencies on specific container versions. EJB: AspectJ supports a wide variety of aspects for EJBs.

Yes. Any product conforming to the J2EE 1.3 or later specifications can be used to run this benchmark. CTS certification ensures that the application server being tested is a J2EE technology-based application server and not a benchmark-special application server that is crafted specifically for SPECjAppServer2004. The CTS certification is validated by Sun Microsystems, Inc.

There are numerous choices of tools available for developing Java and J2EE applications. You can download the Open Source NetBeans IDE for free at http://netbeans.org. Many of the J2EE compatible vendors offer tools that support any J2EE compatible application server.

JBI does not require J2EE (or Java EE). Certain JBI components may require a J2EE JBI implementation, in order to access technologies such as JTA. The Open-ESB project requires J2EE, and runs within a number of J2EE application servers.

J2EE modules are components that may be individually or collectively (by way of an EAR) deployed into a J2EE Server. They include: EARs (.ear), EJBs (ejb-jar), RARs (.rar), and WARs (.war).

J2EE™ stands for Java 2 Platform, Enterprise Edition. It is a set of open software standards designed to simplify application development for large enterprises. Learn more about J2EE™ at http://java.sun.com/j2ee/.

AquaPDF will work with any standards-based J2EE container such as WebLogic, WebSphere, JBoss and others.

ECperf is used for benchmarking J2EE application servers. It consists of a Specification and a benchmarking kit which is designed specifically to test...

You can place dependency libraries packaged as JAR files in the WEB-INF\lib directory of a web application. T?F J2EE containers usually load each application by means of a different class loader, isolating each application from others. T?F
