The direct reference binding component requires the following information to connect to a user-provided SOA invoker:

• Properties:

  A set of properties that defines the DirectConnection for the end service (see oracle.soa.management.facade.Locator).

• ConnectionFactory class name (see oracle.soa.management.facade.Locator).

  The ConnectionFactory class must implement the oracle.soa.api.invocation.DirectConnectFactory interface.

  If the ConnectionFactory class name is not specified, the default oracle.soa.api.JNDIDirectConnectionFactory is used. To use the default connection factory, you must supply the lookup name for the EJB.

• Address used by the external service:

  This address value is not processed by the binding component, but is passed on to the service bean during invocation.

• addressingVersion (optional):

  The default addressing version used is 2005/08.

• useSSLForCallback:

  Use a secure socket layer (SSL) for the callback JNDI connection. If this flag is set to true, then the WS-Addressing replyTo header instructs the service to call back at an SSL JNDI port.

A sample configuration is shown in the following example:

<reference name="HelloReference" ui:wsdlLocation="HelloService.wsdl">
  <interface.wsdl
 interface="http://hello.demo.oracle/#wsdl.interface(HelloInterface)"/>
  <binding.direct connection-factory="oracle.soa.api.JNDIDirectConnectionFactory"
   addressingVersion="http://www.w3.org/2005/08/addressing"
   address="soadirect://syncOut"
   useSSLForCallback="false">
  <property
 name="oracle.soa.api.invocation.direct.bean">MyDirectTestServiceBean#directEjb.Tes
tInvoker</property>
  <property
 name="java.naming.factory.initial">weblogic.jndi.WLInitialContextFactory</property
>
 <property name="java.naming.provider.url">t3://@host:@port</property>
 </binding.direct>
</reference>

The direct binding components support both synchronous and asynchronous invocation patterns. Figure 39-1 describes a sample synchronous invocation pattern and Figure 39-2 describes a sample asynchronous invocation pattern.
