Service-Oriented

Architecture (SOA)

What is SOA?It is an architecture that facilitates the development of applications as services, to provide solutions for frequently changing business requirements

Components of SOA 1. Service Components - Service components are

the building blocks that one can use to construct a SOA composite application

2. Binding Components/Adapters - Binding components establish a connection between a SOA composite and the external world

10

Types of Service Components1. BPEL provides process orchestration and storage of

a synchronous or an asynchronous process. You design a business process that integrates a series of business activities and services into an end-to-end process flow.

2. Business Rules enable you to design a business decision based on rules.

3. Human Tasks provide workflow modelling that describes the tasks for users or groups to perform as part of an end-to-end business process flow.

4. Mediators route events (messages) between different components

5. Spring Context enables you to integrate Java interfaces into SOA composite applications

11

Types of Binding Components1. Web Service - Use for connecting to standards-based

services using SOAP over HTTP

2. JCA Adapters - Use for integrating services and references with technologies (for example, databases, file systems, FTP servers, messaging: JMS, IBM WebSphere MQ, and so on) and applications (Oracle E-Business Suite, PeopleSoft, and so on). This includes the AQ adapter, database adapter, file adapter, FTP adapter, JMS adapter, MQ adapter, and Socket adapter

3. B2B - Use for browsing B2B metadata in the MDS repository and selecting document definitions

4. ADF-BC Service - Use for connecting Oracle Application Development Framework (ADF) applications using SDO with the SOA platform

12

Types of Binding Components5. Oracle Applications - Use for integrating the Oracle

Applications adapter with Oracle applications

6. BAM Adapter - Use for integrating Java EE applications with Oracle BAM Server to send data, and also use as a reference binding component in a SOA composite application

7. EJB Service - Use for integrating SDO parameters or Java interfaces with Enterprise JavaBeans

8. Direct Binding - Use to invoke a SOA composite application and exchange messages over a remote method invocation (RMI) in the inbound direction and to invoke an Oracle Service Bus (OSB) flow or another SOA composite application in the outbound direction

9. HTTP Binding - Use to integrate SOA composite applications with HTTP binding

ScenarioCreate an application for Open AP Invoice Conversion using SOA

1. Install VM

2. Module 1 - Synchronous BPEL Process

3. Module 2 - Asynchronous BPEL Process

https://drive.google.com/file/d/0B6rekvPGxvGyUWdFaGN4aHVZcTg/edit?usp=sharing

15

Steps 1. Create SOA Application

2. Create SOA Project

3. Create Synchronous BPEL Process (covered in Module 1 document) which performs validation and insertion as described below

i. Create DB Adapter to call a PL/SQL stored procedure that performs validations

ii. If a record fails in validation, then display the validation error message using Throw Activity

Else insert the record into interface table using DB Adapter

4. Create Asynchronous BPEL Process (covered in Module 2 document) in another SOA project which reads a file, calls a web service and submits the concurrent program as described in next steps

16

Steps 5. Create File Adapter for reading a file from a

directory

6. Get the count of number of records using getNodes function

7. Loop through the number of records using While Activity

8. Map the columns from data file to interface table using Assign Activity

9. Call synchronous process/web service (created in step 3) to validate and insert the data into interface table

10.Create Oracle Applications Adapter to call AP Import Concurrent Program after the loop
