In this section you learn how to set up your environment, configure your resources, and start BEA AquaLogic Service Bus so that you can create the solutions that implement the business cases presented in the tutorial. You must complete the steps in this section before you start the tutorials. These tutorials use the AquaLogic Service Bus example suite as a basis for instruction.

The tutorials describe a typical Mortgage broker scenario for a loan application request. A primary mortgage company uses AquaLogic Service Bus to route loan applications to appropriate business services. The loan applications are routed to different business services depending on certain qualifying criteria, such as the requested interest rate and the requested principal amount.

The applicants credit rating information is required in one of the scenarios to complete the loan request. The tutorials represent typical use case scenarios for AquaLogic Service Bus. You will learn how to configure and use AquaLogic Service Bus to resolve the business scenarios presented in the specified use cases. Complete the first tutorial to become familiar with AquaLogic Service Bus. You can build on what you learn in the first tutorial by completing the subsequent tutorials.

These tutorials explore the basic functionality of AquaLogic Service Bus, including message routing and enrichment. The files including pre-built business services that support the building of the tutorial solutions are located in the following directory:. The tutorial files contain properties that you must set to run the tutorials. Each business service also has a set of files associated with it. In the tutorial you use four different business services.

The files structure for each of the business services is the sameā€”the directory structure for one of the business services, the normal service, is described in the following table.

You can explore the other directories as an exercise. This file contains business service build and deployment properties. The files contained in this folder are those required by the normal business service.

The same files structure exists for the other three business services used in this tutorial manager , large , credit. The Java client with which each of the business services interacts. For this tutorial, create a domain named ServiceBusTutorial , and select development mode and the default PointBase database. To develop and run the AquaLogic Service Bus tutorials you must modify some of the configuration properties.

The associated files are located in the following directory:. Folder Name. This folder contains the files that support the development and running of the AquaLogic Service Bus tutorial. While developing the tutorial you will modify some of the files contained in this folder, such as examples.

To deploy the business services to your running tutorial domain, you must modify the properties responsible for specifying the WebLogic Server behavior. You do so in the WebLogic configuration section in the following file:. Edit the setEnv script setEnv. Use setDomainEnv. This step is only for Windows users. On Windows machines, a classpath length problem prevents you from running ant tasks and executing the tutorial.

The workaround uses the subst command to shorten the classpath passed by ant. Follow these steps to shorten the classpath:. A server command console window, which shows status information about Weblogic Server is displayed. Note: If you created a production mode domain, you are required to enter a valid username and password to start the server.

You must start the server before building the Web services. After the server is started, you must run a build script to:. Four business service folders exist in this directory. The following steps describe how to build and run each of the business services. A message indicating whether the command was successfully executed is displayed on the console. A message from the business service is output to the command line.

The message indicates whether the Web service was run successfully. For example, if WebLogic Server is running on your local machine using the default port configuration, enter the following URL in your browser:.

Enter the username and password you specified when you created the AquaLogic Service Bus domain. After you complete the steps required to set up the tutorials, you are ready to proceed to Tutorial 1.

Each of the tutorials includes instructions for designing and configuring the AquaLogic Service Bus resources, followed by test sections that you can use to test the configurations you complete. About the Scenarios The tutorials describe a typical Mortgage broker scenario for a loan application request.

The following tutorials are available: Tutorial 1. Routing a Loan Application demonstrates how AquaLogic Service Bus facilitates routing of messages within an enterprise. Tutorial 2. Transforming a Loan Application describes how a proxy service is configured with a routing node, transformations, and a Web service callout WS-Callout to allow content based routing and message enrichment through AquaLogic Service Bus.

Install AquaLogic Service Bus. Create a new AquaLogic Service Bus domain in which to develop the tutorials. The Configuration Wizard guides you through the process of creating a new domain using the configuration templates. Change the hostname to the name of the machine on which your ServiceBusTutorial domain is running. Change the port number to the port number of the tutorial domain. Enter the username you specified when creating the domain.

Enter the password you specified when setting up the domain. Change the server name to the name you specified when you created the domain if you specified a name other than the default name AdminServer assigned by the Configuration Wizard. In the examples directory, on the command line, run the following command:. Edit the setDomainEnv.

In the setDomainEnv. The instruction looks like:. Identify three unused drive letters for example, X, Y, and Z and add the following code to the beginning of the file:. For the example:. Save the changes and close setDomainEnv. Run the setDomainEnv. Run setDomainEnv. In the command window, ensure that you have run the setenv script, as described in To Run the setEnv Script. Change to the normal directory: cd normal.

To deploy the Web service, enter ant , then press Enter. To test the deployed Web service, Enter ant run then press Enter. This file sets the environment properties. For each business service:.

The jws Web service definition. The message definition. The build script is used to build each of the services.
