Java SOA Training

If you've read through the texts which give you an introduction to SOA or Web Services, you will often find them to be quite frustrating, and the reason for this is because they spend too much time referencing business processes which are elaborate, and which can be built on top of them. Since SOA, along with WSDL, are now independent of a programming language, many are wondering whether or not they should pick Java. Turning to this book can give you information on this.

1. Bind Web Services in ESB-Web Services Gateway

   Bind Web Services in ESB-Web Services Gateway Since SOI is all about integrating multiple SOA-based systems web services play a critical role in the integration space. This chapter is all about the importance of web services in integration. We will use the samples to illustrate how to bind web services with the ServiceMix ESB to facilitate integration. This

2. ServiceMix HTTP

   ServiceMix HTTP HTTP HTTP is the World Wide Web www protocol for information exchange. HTTP is based on character-oriented streams and is firewall-friendly. Hence we can also exchange XML streams which are XML encoded character streams over HTTP. In a web service we exchange XML in the SOAP Simple Object Access Protocol format over HTTP.

3. Consumer and Provider Roles

   Consumer and Provider Roles When we speak of the Consumer and Provider roles for the ServiceMix components the difference is very subtle at first sight but very important from a programmer perspective. The following figure shows the Consumer and Provider roles in the ServiceMix ESB The above figure shows two instances of servicemix-http deployed

4. Servicemix-http XBean Configuration

   Servicemix-http XBean Configuration The servicemix-http components supports the XBean-based deployment. Since the servicemix-http component can be configured in both the consumer and provider roles we have two sets of configuration parameters for the component. Let us look into the main configuration parameters servicemix-http as consumer

5. Servicemix http Lightweight Configuration

   servicemix-http Lightweight Configuration In addition to the XBean-based configuration servicemix-http can also be deployed based on the lightweight mode to use in an embedded ServiceMix. The configuration would be as follows geshibot language XML" geshibot Web Service Binding Sample We will now look at a complete

8. XBean based servicemix http Binding

   XBean-based servicemix-http Binding For XBean-based deployment of servicemix-http our xbean.xml matches the following geshibot language XML . geshibot The previous execution of ant has already built and packaged the service assembly for the sample. Deploying and Running the Sample To deploy the ServiceMix sample we have the

9. Access WSDL

   Access WSDL and Generate Axis Stubs to Access the Web Service Remotely Now for the really cool stuff. As we discussed earlier we have set up the ServiceMix as a separate web service gateway in front of the actual web service deployment. Now we have to check whether we can access the WSDL from the ServiceMix. For this we can point our browser using
