The different packages used in the Direct Binding Invocation API are as follows:

• oracle.soa.management.facade.Locator

  The oracle.soa.management.facade.Locator interface exposes a method, createConnection, which returns a direct connection. The Locator exposes the method shown in the following example for returning the DirectConnection.

  import java.util.Map;
  public interface DirectConnectionFactory {
      DirectConnection createDirectConnection(CompositeDN compositeDN,
   String serviceName) throws Exception;
  

  You can use the LocatorFactory implementation to obtain the DirectConnection, as shown in the following example:

  Hashtable jndiProps = new Hashtable();
  jndiProps.put(Context.PROVIDER_URL, "t3://" + hostname + ':' + portname + "/soa-infra");
  jndiProps.put(Context.INITIAL_CONTEXT_FACTORY,"weblogic.jndi.WLInitialContextFactory");
  jndiProps.put(Context.SECURITY_PRINCIPAL,"weblogic");
  jndiProps.put(Context.SECURITY_CREDENTIALS,"welcome1");
  jndiProps.put("dedicated.connection","true");
  Locator locator = LocatorFactory.createLocator(jndiProps);
  CompositeDN compositedn = new CompositeDN(domainName, compositename, version);
  String serviceName = "HelloEntry";
  return locator.createDirectConnection(compositedn, serviceName);
  

• oracle.soa.api.invocation.DirectConnection

  The DirectConnection interface invokes a composite service using direct binding. For more information, see Java API Reference for Oracle SOA Suite Infrastructure Management.

• oracle.soa.api.message.Message

  The Message interface encapsulates the data exchanged. For more information, see Java API Reference for Oracle SOA Suite Infrastructure Management.
