SOA : Tutorial - Hello World

Lets create the equivalent of the famous Hello World program using Oracle SOA.
We will create a SOA composite which will take a name, prefix it with Hello and return the output.

Prerequisites:
1) You need to Create a SOA project with an empty composite.
2) You need to Create an Application server connection to your SOA server.

---

1) Drag and drop 'BPEL Process' on to the Composite.

---

2) Enter a name for the BPEL process and change the Template to 'Synchronous BPEL Process'.
 

---

3) We can see the newly created BPEL process in the Components(center) lane in the SOA Composite.
     Double click the BPEL process to open the BPEL editor.

---

4)  We can see the BPEL process in the editor.
      Any operation/logic needs to be added between the receiveInput and replyOutput activities.

---

5) Drag and drop an Assign activity between the receiveInput and replyOutput

---

6) Double click the Assign activity to edit it.
    Drag and drop the expression from the top right corner to the center.

---

7) In the expression builder enter the following : concat('Hello ',)
    After entering the above, put the cursor before the last brace.
    In BPEL Variables select :
    Process --> Variables --> inputVariable --> payload --> client:process --> client:input
    Now click Insert Into Expression.
    Your expression should look as shown below.
    Click OK

---

8) Now select the expression and drag it to connect to the following in the right side pane :
outputVariable --> payload --> client:processResponse --> client:result
Click OK.

---

9) Now the Assign activity which prefixes the Hello to the input is ready.

---

10) Deploy the SOA composite :
      Right-Click the SOAProject and select : Deploy --> SOAProject
      In Deployment Action select Deploy to Application Server and click Next.

---

11) Click Next in the Deploy Configuration

---

12) Select the application server connection to your SOA server and click next.

---

13)  Select your SOA server and click finish.

---

14) You can see if the deployment is successful from the deployment log.

---

15) To test the composite go to the enterprise manager(weblogic/welcome1) and click the name of your SOA composite in the home page.

---

16) Click Test in the composite details page.

---

17) In the Test Web Service page enter a value for the input field in the request tab and click Test Web Service.

---

18)  You will see the result in the Response tab.
