SOA 11g - Preference Property/Deployment Descriptor

Deployment descriptors are BPEL process service component properties used at runtime by Oracle WebLogic Server, Oracle Enterprise Manager, or both. Basically it is like a variable whose value we can change from EM console without doing any code change

In this post , I will explain you step by step process to implement preferences in your code.

Step 1: First of all you need to define Preference property in Composite.xml file.

· Open Composite.xml file in source mode.

· Add Preference property in inside Component section. Here I am using it for Email so my property name is "bpel.preference.Email", you can give it any name as per your requirement.

bpel.preference.{CustomName}

<implementation.bpel src=" CustomerNotification.bpel"/>

<property name="bpel.config.transaction">required</property>

</component>

Step 2 : Use this preference property inside BPEL.

To use this property inside BPEL you need to use ora:getPrefernce("CustomName") function.

ora:getPreference('Email')

Step 3: Update preference property value in EM console.

We can update this property from MBean Browser inside EM console.
Go to EM console (http://host:7001/em)
Navigate to "Farm_base_domain" -> "Weblogic Domain" folder -> Right click on your domain -> "System MBean Browser"

Go to "oracle.soa.config" -> "soa-server" -> "SCAComposite" -> Choose your composite

Then navigate to "SCAComposite.SCAComponent" -> your component name -> Click on "properties"
Now you can see all the preference properties that you defined in your composite. You can change preference property value here.
