SOA and Web Services

SOA and Web Services

1. What is SOA (Service Oriented Architecture)?
   An introduction to the Service Oriented Architecture.  
     
2. Web Services - An Introduction
   The next generation of distributed computing has arrived. A Web service is a unit of managed code that can be remotely invoked using HTTP, that is, it can be activated using HTTP requests.  
    
3. Why Web Services?
   In this section of Web Services tutorials series we will understand why Web Services are developed and what are the benefits of using Web Services for  the development of  Enterprise applications.
     
4. Introduction to Web services technologies 
   Before understanding why web services are popular or so important, you should first assess ‘What is Web Services, what’s its use and how does it work?’ The nature and functionality of web services have made it very popular.
    
5. Develop Database driven webservice
   In this tutorial we will learn how to develop database driven Web services.
    

	Web Services Examples and code
	Apache Axis2   Develop Web Services using NetBeans Apache Axis2 Tutorial The Axis 1.5 is the latest release at the time of writing of this tutorial. We will use Apache Axis2 1.5 for developing and testing our example code.    Apache Axis2 Eclipse plugin Learn how to install and use Axis2 plugin in Eclipse IDE.      Develop and Test Web services in Net Beans IDE The NetBeans IDE is one of the advance rapid application development tools. It helps the developer to quickly develop the applications.

1. J2EE Web Service Development with Attachments Using Axis
   This article discusses the development of a java web service that takes DIME or MIME attachment as input and returns the output as an appropriate attachment. (Author: Murthy Vaddiparthi)

2. Developing Simple Web Service
   In this tutorial we will create a simple web service and a client web application using eclipse IDE along with Lomboz plug in. We will also deploy and test the web service on Tomcat 5.5.4 web application server. This application, while simple, provides a good introduction to Web service development and some of the Web development tools available.

3. Exposing a javabean (jws)  from Tomcat/Axis
   In this experiment, we attempt  exposing a javabean (jws)  from Tomcat/Axis and consuming that service in an ASP.net program.
    
4. Understanding Apache Axis
   Apache Axis can be thought of as an improved implementation of Apache SOAP.  While Apache SOAP used DOM for XML parsing, Axis makes use of SAX and hence it is more efficient and fast.  Secondly, it supports automatic generation of WSDL (Web Service Description Language) file.
        
5. Creating and testing an EJB in WebLogic Server
   In this section you will learn how to create and test an EJB in WebLogic Server.
    
6. Drop-In Deployment in Apache AXIS
   This tutorial discusses about drop-in deployment in Apache AXIS.
       
7. Apache AXIS-Deployment using WSDD File
   In this part, we will follow the WSDD method.  We have already created sqlaxisbean.java as explained in the last article.  We used it as sqlaxisbean.jws (drop-in method).  There was no necessity to compile this file.But in WSDD method (web-service deployment descriptor), we should compile this file.Next, we create the WSDD file.  Then, we deploy this bean to tomcat.  We may have to restart the tomcat4.1 webserver.
       
8. Exposing EJB as XML-Webservice
   In this web service tutorial you will learn how to expose an EJB as XML-Webservice using Axis.
    
9. Accessing ejb-webservice through WAP
   This tutorial discusses how to Access ejb-webservice  using  WAP (Wireles-Application Protocol) 
    
10. J2ME CLIENT FOR EJB & EJB-WEBSERVICE
    In  the previous section,we've dealt with how to write WAP client for accessing ejb. In the same way, we are going to see how to write J2ME client for ejb.
    
    Developing and deploying Web Services on Apache Geronimo Application Server
    
11. Understanding Apache Geronimo Application Server
    Apache Geronimo is a open source JavaEE( or J2EE, old name) application server. This section introduces you with the Apacehe Geronimo Application Server.
      
12. Developing Axis Web services with XML Schemas.
    Developing SOAP based web services (Note: If you are looking for RESTful web services, please refer Axis2 ) with Axis1.4 is pretty easy, if the consuming clients are purely java. The real challenge comes if you want to make your web services interoperable with wide range of clients including .Net, Perl, C++ and Flash MX etc.
