SOA 11g - Set/Get Preference Property and change it on runtime from Oracle EM

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.

Set Preference property in Composite.xml: 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}

 <component name="CustomerNotification">

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

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

        <property name="bpel.config.oneWayDeliveryPolicy">sync</property>

        <property name="bpel.preference.Email">test@test.com</property>

    </component>

Set Preference property in Composite.xml: Use this preference property inside BPEL.

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

                              ora:getPreference('Email')

Change Preference property from EM: 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.
