Oracle SOA 11g - HTTP Binding Adapter

Invoking REST services in SOA 11g using HTTP Binding :

If you want to invoke HTTP methods like GET or POST in SOA composite application for that HTTP Binding Adapter is available that can be use to invoke REST services. For example if you have a web application that has a servlet that takes HTTP GET request with some parameter and returns an XML response.

So here I am demonstrating with an example. Create a SOA project with empty composite

Create an sample xsd

<?xml version="1.0" encoding="windows-1252" ?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
            xmlns="http://www.example.org"
            targetNamespace="http://www.example.org"
            elementFormDefault="qualified">
  <xsd:element name="Request">
    <xsd:complexType>
      <xsd:sequence>
        <xsd:element name="FName" type="xsd:string"/>
        <xsd:element name="LName" type="xsd:string"/>
      </xsd:sequence>
    </xsd:complexType>
  </xsd:element>
  <xsd:element name="Response">
    <xsd:complexType>
      <xsd:sequence>
        <xsd:element name="Name" type="xsd:string"/>
      </xsd:sequence>
    </xsd:complexType>
  </xsd:element>
</xsd:schema>

Drop a Http Binding adapter in exposed services name it HttpTest click next in HTTP Binding Configuration.

 

 

 

 

Here you can specify type as service or reference, service type one way or request response, operation name and type of HTTP GET or POST.

In Request message either you can select existing element from a schema or select the wizard to create it .

 

Create a bpel process with Define Service later template

Wire service and bpel process

In Bpel process drop a receive activity with create instance checked and connect it with partner link

 In assign activity use concat function to assign name to output variable.

Deploy the application and test this through web browser...!!!
