BPEL Pick Activity In Oracle SOA 11g

A Pick activity is a structured BPEL  and is pa rt of our process definition, and a Pick activity can contain one or more OnMessage and OnAl arm activities.

Used to have the process wait until one of a set
of events is triggered
– Message events via onMessage element
– Alarm events via onAlarmelement And Plays a role in the lifecycle of a business
process
– If createInstance="yes"
z Instructs the BPEL engine to create a new process instance
z As a result of receiving one of a set of possible messages
– Each onMessage is equivalent to a receiveactivity
with the createInstance="yes"
– No alarms are permitted in this case

The Pick activity forces the process to wait until one of a set of events is triggered.

Oracle SOA BPEL File Adapters Read Write

The most common scenarios in SOA11g Integration is the loading of a file into the product from an external source. In Oracle SOA Suite11g there is a File Adapter that can process many file types into our BPEL process.

For this example we will use the File Adapter to load a file of user and emails to update the user object within the Oracle Utilities Application Framework. Remember you can repeat this process with other objects and other file types. Again I am illustrating the ease of integration.

The first thing is to create an empty BPEL process that will hold our flow. In Oracle JDeveloper this can be achieved by specifying the Define Service Later template (as other templates have predefined inputs and outputs and in this case we want to specify those). So I will create simpleFileLoad process to house our process.

Difference Between Concreate WSDL And Abstract WSDL

● An abstract WSDL document describes what the web service does, but not how it does it or how to contact it. An abstract WSDL document defines:

the operations provided by the web service.

the input, output and fault messages used by each operation to communicate with the web service, and their format.

● A concrete WSDL document adds the information about how the web service communicates and where you can reach it. A concrete WSDL document contains the abstract WSDL definitions, and also defines:

the communication protocols and data encodings used by the web service.

the port address that must be used to contact the web service.
