Preference in BPEl

Setting and Getting Preference Properties:

Preference Properties :
from front end, not while deploying the sar.
For eg Datasource Value of jca file can be modified using these properties from front end. In composite.xml ,
where the component name tag is there , add the following tag for bpel preference.
<property name="bpel.preference.name">value</property>
Eg:
<component name="BPELProcess1"> <implementation.bpel src="BPELProcess1.bpel"/>
<property name="bpel.preference.name">value</property> </component>Object 1

This can be used to make any run time changes in parameters

 Now we can use the function ora:getPreference(“name”)in our bpel process to retrieve the value of the preference.

Watch the naming convention. It expects it to start with “bpel.preference”.
Also please check the ora:getPreference should contain “” or will throw xpath invalid error
Setting the Property value from emconsole as a configuration change:
On the left go to :

• Farm_soa_domain > Weblogic Domain > soa_domain > right mouseclick and select ‘System MBean Browser’.
  
• Navigate to Application Defined MBeans > oracle.soa.config > Server : soa_server1 > SCAComposite > your_project > SCAComposite.SCAComponent > your bpel_process.
  
• Select the Attribute ‘Properties’
  
• Change the value of our preference and click apply.
  
• After clicking ‘Apply’ click ‘Return’.
  
• To persist the new value of the preference after server restart
  
• Go to the ‘Operations’ tab and click on the ‘save’ operation. Click ‘Invoke’ and ‘Return’
  If you now restart the service the changed value of your preference with still be there.
