- J2EE WEB SERVICE STANDARDS.
- " Many observers assume that J2EE includes support for Web services, but an examination of the 600-plus pages of the J2EE specification reveals that Web services is never specifically mentioned. Those who wish to architect solutions that include both J2EE and Web Services will have to look outside the specification for guidance. ...

- Allow rapid development of management solutions for J2EE .
- As the installed base for J2EE platforms and J2EE applications grows, the need for management tools is becoming increasingly apparent. In order to be effective, J2EE management tools need the ability to transparently manage a network of multiple J2EE servers, which could consist of multiple vendor implementations of the platform. The current selection of J2EE management tools are implementation-specific and weaken the platform in the area of distributed management. ...

- Enterprise JavaBeans and J2EE.
- Description: This hands on course provides participants with the information and lab experience necessary to develop and deploy robust J2EE (Java 2 Enterprise Edition) applications. The focus is on building reusable components that exploit the services the J2EE platform provides via its component containers. The two most popular containers in the J2EE specification are the Web Container (which hosts HTML pages, servlets and JSP Pages) and the EJB Container (which hosts Enterprise JavaBean components). ... Since the deployment descriptor of these applications is an XML file that is standardized across J2EE implementation servers, the participant will obtain the necessary experience to deploy applications across the various servers that meet Sun's J2EE specification (including WebSphere, Oracle, WebLogic and many others). ... Comprehensive hands on coding labs ensure that by the end of the class students will be able to write and deploy applications that exploit J2EE services using EJBs, servlets, JSP and the J2EE framework.

- J2EE meets Web services10/1/2003 By Sean Jiang, Ash Parikh, Rajesh Pradhan.
- J2EE grows up.
- What began in the mid-90s as the revolution called Java has now matured into three branches: Java 2 Standard Edition (J2SE), Java 2 Enterprise Edition (J2EE) and, more recently, Java 2 Micro Edition (J2ME). ...
- With noteworthy forerunners such as CORBA and DCOM to learn from, Java thought leaders applied familiar concepts such as RPC and RMI to create a robust and scalable component-based environment called J2EE that would provide built-in features such as security and transaction support. What this meant for an enterprise was that enterprise application developers could concentrate on developing business logic and leave plumbing worries to the J2EE environment or container.
- According to the J2EE specification, we have API-level access to develop the following software components in J2EE:.
- A typical J2EE system can be divided into three tiers: the client tier, which comprises Web and non-Web browser-based client components; the app server tier, which is composed of Web components and Session EJBs; and the back-end tier of data representation and data interaction components such as Entity EJBs.
- J2EE Web services: A marriage of convenience.
- As specified in the following snippet taken from the J2EE specification, the J2EE platform contains details on the implementation, assembly, deployment and consumption of Web services: J2EE provides full support for both clients of Web Services as well as Web Service endpoints. ... The Web Services for J2EE specification fully defines the deployment of Web Service clients and Web Service endpoints in J2EE, as well as the implementation of Web Service endpoints using enterprise beans. ...
- The life cycle of J2EE components and Web services is not dissimilar; they almost mimic one another as both have sprung from similar distributed computing ideologies. From modeling a Web service to its creation, binding, deployment, publishing and consumption, a Web service presents no new tenets for understanding, and its inclusion in the J2EE component stack is a logical addition to enable loosely coupled interaction between applications. The combination of J2EE and Web services seems to be a perfect match: .
- * One can expose J2EE components as Web services, thus enabling loose coupling of components.
- * Web services realizations can reuse many of the features of the J2EE platform, such as security and transactions.
- * Since a Web service is based on open standards, it ensures vendor-agnostic behavior, which was the intent of J2EE.
