LIST OF EXPERIMENTS

1. Develop at least 5 components such as Order Processing, Payment

Processing, etc., using .NET component technology.->

2. Develop at least 5 components such as Order Processing, Payment

Processing, etc., using EJB component technology.->

3. Invoke .NET components as web services.->

4. Invoke EJB components as web services.->

5. Develop a Service Orchestration Engine (workflow) using WS-BPEL and

implement service composition. For example, a business process for

planning business travels will invoke several services. This process will

invoke several airline companies (such as American Airlines, DeltaAirlines etc. ) to check the airfare price and buy at the lowest price.->

6. Develop a J2EE client to access a .NET web service.->

7. Develop a .NET client to access a J2EE web service.->

6/22

Microsoft Visual Studio is an integrated development

environment (IDE) from Microsoft. It is used to develop computer

programs for Microsoft Windows superfamily of operating

systems, as well as web sites, web applications and web services.

Visual Studio supports different programming languages C, C++

(via Visual C++), VB.NET (via Visual Basic .NET),ASP.NET, C#

(via Visual C#), C# .NET and F#.

It also supports XML/XSLT, HTML/XHTML, JavaScript and CSS.

Ex.No:1 What is a .NET Component?

A component is a special type of executable built from a .NET project.

After compilation the component is typically referenced by applications

needing the services provided by the component.

In many .NET Web environments, components run on the Web server

and provide data and other services.

Steps:

1.Create a component

2.Create a application to refer the component

Ex.No:2 What is EJB Component?

The Enterprise JavaBeans (EJB) technology defines a model for the

development and deployment of reusable Java server components,

called EJB components.

An EJB component is a nonvisual server component with methods that

typically provide business logic in distributed applications.

EJB component implementationThe Java class that runs in the server

implements the beans business logic. The class must implement the

remote interface methods and additional methods for lifecycle

management.

EJB Component Types

Stateful session beans

Stateless session beans

Entity beans

Stateless session beans

A stateless session bean manages tasks that do not require the keeping

of client session data between method calls.

Ex.No:3 Web Services: All About Interoperability

Web Services are self-contained, modular applications that can be

described, published, located, and invoked over a network.

They are an emerging technology that are based on service-oriented

architecture (SOA) and enable new and existing applications to be

integrated using of XML as data format over standard network

protocols such as HTTP for transportation.

Web Services are based on "open" environment and standards, which

ensures that a Web Service can be located and used, no matter where it

is, what platform it runs on, or who developed it.


14/22

Microsoft .NET

Microsoft .NET is the Microsoft XML Web Services platform.

It provides built-in support for building and consuming standards-

based Web Services. It enables the creation and use of XML-based

applications, processes, and Web sites as Web Services.

Through just a single line of code and/or setting a value of an

attribute, it is possible to turn an application into a Web Service in

the .NET environment.

Furthermore, by default all inter-process communication is done

using the SOAP standard.

Ex.No:4 Java 2 Platform, Enterprise Edition

(J2EE)

The new APIs released by Sun, as part of J2EE 1.3, provide a top-to-

bottom, end-to-end solution for a Web Services-based architecture.

J2EE 1.3 simplifies integration with new technologies for Web

Services, such as Java Messaging Service ( JMS), J2EE Connector

Architecture ( JCA), Java API for XML Messaging (JAXM), Java

API for XML Processing (JAXP), Java API for XML Registries

(JAXR), and Java API for XML-based RPC (JAX-RPC).

Ex.No:5 WS-BPEL

BPEL is used as a server side programming language. This means that

companies will often either deploy BPEL as something to serve and track a

customer request or they will deploy a BPEL server as a nice easy to use

proxy to all their legacy systems.

In either case, a common chain of events will be as follows:

Web Service client (user) requests something from the server (perhaps via a

browser or another server)

Client request is received by the BPEL server.


19/22

Client request is identified as a new request and a new BPEL process is

used to serve that client

Client continues to interact with the BPEL process, making requests etc,

until the interaction is complete

BPEL process disappears and client goes about it's business

This automatic creation of BPEL process instances in response to client

requests is called 'create on demand'.


20/22

BPEL is an XML programming language. As a programming

language it has three basic components,

Programming logic - BPEL

Data types - XSD (XML Schema Definition)

Input/Output (I/O) - WSDL (Web Services Description

Language)

Ex.No:6

Create the application from which you want to access a Web service.

Add a Web reference for the Web service with which your

application will interact.

Access the methods of the Web service as you would any other

component.

The two lines of code in bold represent the code that is necessary to

access the Web service.

Step 1Create the Web Service

Step 2Consume the Web Service Source File

http://localhost/suppliers.asmx?WSDL

the Web service.
