In this simple scenario we will process orders that adhere to the following XSD
btw. a great resource that I often refer to is Antony Reynolds/Matt Wright --> Oracle SOA Suite 11g Developers Guide. If you don't already have it - then get it!
Ok back to business...
The underlying DB tables are as follows (I've created them in SCOTT's schema)–
DDL is available at Appendx A
Scenario
We are used to having payloads that contain all of the order attributes. We can imagine an Order Entry UI where the Order & customer details are entered. We could pass all of this on to BPM via the payload. However a more efficient way may be to leverage SDOs and just pass the keys e.g. OrderId, CustID on to BPM. BPM can then load the data in just in time mode from the DB using the SDO.
Setup
You need to have your DB schema installed. I create 1 customer so that I’ve something to test.
Create an ADF App in JDeveloper
This app will contain ADF-BC artifacts that we will expose via a Service Interface.
Set App name in project properties to something more readable as the default.
Create a BC App Module based on the tables we created.
Open the AppModule and click on Service Interface, then the +
Do the same for the other views.
FYI: Here is an extract from the official docs, detailing the operations.
The following files are generated
Test
We can test the SDO using OrdersAMServiceImpl
Running this app will deploy it to the integrated WLS and open the test page in your browser.
Select the getAmCustomerView1 operation
- Enter 1 as the cust id
Deploy to SOA Admin Server
Change the wsdl url to point to the target port
- Per default it is generated for 7101 (the JDev integrated WLS).
Add the following to the weblogic-application.xml
This enables us to register the SDO as an RMI Service.
The Datasource used by ADF-BC (jdbc/scottDS) needs to be XA aware.
The default generated/deployed by ADF-BC is not what we require, so we have to do 2 things - de-activate auto-generation of the weblogic-jdbc.xml and create the necessary datasource on our target WLS.
Using the WLS console, create a datasource jdbc/scottDS.
Per default it will be XA aware.
Create a new deployment profile of type Business Components Service Interface
Give the application a more meaningful name
Deploy from the Application Menu
Test
Leverage SDO in a BPM Composite
Create a BPM app
In Composite.xml --> add an ADF-BC Service (Reference).
Note: Registry name set to ADF app name + _JBOServiceRegistry.
Now we add a FileAdapter(ReadOrders) which will pass in the custID.
In the BPM designer, set Start implementation to ReadOrders.
Add a Service activity to retrieve the customer from the DB.
Deploy & test

SOA Suite 11g: Test 2 Production via Config Plan
Scenario:
I have a simple SOA composite that calls a validation service.
I develop this in my test environment using the validation web service running on the test server. Now I'm deploying to production and need to leverage the web service running on the production server.
Create a new Application in JDev that will contain 2 web service projects -
Expose as web services
Deploy the web services to WLS.
Check the 2 URLS:
http://localhost:7001/Test-ValidatePerson/ValidationServicePort?WSDL
http://localhost:7001/Prod-ValidatePerson/ValidationServicePort?WSDL
Create a SOA composite with a sync BPEL process.
Invoke the test service from BPEL
Deploy & Test
back in JDev, right click on composite.xml and select Generate Config Plan
Here I can replace the Test with the Prod WSDL
Re-deploy, selecting the config plan
Re-test

SOA Suite 11g - FTP Adapter
Here is a simple lab demonstrating use of the FTP adapter.
I'm using FileZilla as my FTP Server.
I created the following directories
FTP Server Configuration
I create a user NiallC/NiallC
and configure the shared folders as follows -
Create FTP Adapter artifacts using WLS Console
Deployments --> FtpAdapter --> Configuration --> Outbound Connection Pools --> New
Edit the properties as follows -
host=localhost
password=NiallC
port=21
username=NiallC
serverType=win
Create a new SOA app
In this example I read in an(GET) order and then write it out (PUT).
Configure the read adapter as follows -
Configure the write adapter as follows -
Add the Mediator and specify the transformation.
That's it.
