                                                       javax.xml.namespace.QName serviceName,
                                                       java.lang.String endpointName)
                                                       throws javax.jbi.JBIException,

Activates the named endpoint with the NMR. Activation indicates to the NMR that this component is ready to process requests sent to the named endpoint.

Note that the JBI implementation may call this component's Component#getServiceDescription(ServiceEndpoint) method before returning from this method call; the component's implementation must be ready to supply service description metadata before the result of this activation call (a ServiceEndpoint) is known.

Parameters:

interfaceName - qualified name of the interface the endpoint exposes; must be non-null.

serviceName - qualified name of the service the endpoint exposes; must be non-null.

endpointName - the name of the endpoint to be activated; must be non-null and non-empty.

Returns:

a reference to the activated endpoint; must be non-null.

Throws:

javax.jbi.JBIException - if the endpoint cannot be activated.

                               java.rmi.RemoteException

Deactivates the given endpoint with the NMR. Deactivation indicates to the NMR that this component will no longer process requests sent to the named endpoint.

Parameters:

endpoint - reference to the endpoint to be deactivated; must be non-null.

Throws:

javax.jbi.JBIException - if the endpoint cannot be deactivated.

java.util.logging.Logger getLogger(java.lang.String suffix,
                                   java.lang.String resourceBundleName)
                                   throws javax.jbi.JBIException,
                                          java.rmi.RemoteException

TODO getLogger return a simple Logger, not integrated to the platform Get a logger instance from JBI. Loggers supplied by JBI are guaranteed to have unique names such that they avoid name collisions with loggers from other components created using this method. The suffix parameter allows for the creation of subloggers as needed. The JBI specification says nothing about the exact names to be used, only that they must be unique across components and the JBI implementation itself.

Parameters:

suffix - for creating subloggers; use an empty string for the base component logger; must be non-null.

resourceBundleName - name of ResourceBundle to be used for localizing messages for the logger. May be null if none of the messages require localization. The resource, if non-null, must be loadable using the component's class loader as the initiating loader.

Returns:

a standard logger, named uniquely for this component (plus the given suffix, if applicable); must be non-null.

Throws:

javax.jbi.JBIException - if the resourceBundleName has changed from a previous invocation by this component of this method with the same suffix.

java.rmi.RemoteException - impossible to realize a remote access

Get a reference to the MBeanNames creator for use in creating custom MBean names.

Returns:

reference to the MBeanNames creator; must be non-null.

Throws:

Returns:

a reference to the MBean server; must be non-null.

Throws:

java.rmi.RemoteException - impossible to realize a remote access

getNamingContext

javax.naming.InitialContext getNamingContext()
                                             throws java.rmi.RemoteException

TODO getNamingContext not integrated Get the JNDI naming context for this component. This context is a standard JNDI InitialContext but its content will vary based on the environment in which the JBI implementation is running.

Returns:

the JNDI naming context; must be non-null.

Throws:

java.rmi.RemoteException - impossible to realize a remote access

getTransactionManager

java.lang.Object getTransactionManager()
                                       throws java.rmi.RemoteException

TODO getTransactionManager not integrated Get the TransactionManager for this implementation. The instance returned is an implementation of the standard JTA interface. If none is available, this method returns null.

The object returned by this method is untyped, to allow this interface to be compiled in environments that do not support JTA. If not null, the object returned must be of type javax.transaction.TransactionManager.

This downcast is necessary because JBI is used in environments that do not support JTA (i.e., J2SE). Explicit use of JTA types would cause compilation failures in such environments.

Returns:

A TransactionManager instance, or null if none is available in the execution environment.

Throws:

java.rmi.RemoteException - impossible to realize a remote access

getWorkspaceRoot

java.lang.String getWorkspaceRoot()
                                  throws java.rmi.RemoteException

Get the root directory path for this component's private workspace.

This method MUST return the file path formatted for the underlying platform.

The returned value must indicate a valid file path that the component may use to write files to, and read files from.

Returns:

the private workspace root path, in platform-specific form; must be non-null and non-empty.

Throws:

java.rmi.RemoteException - impossible to realize a remote access

registerExternalEndpoint

void registerExternalEndpoint(javax.jbi.servicedesc.ServiceEndpoint externalEndpoint)
                              throws javax.jbi.JBIException,
                                     java.rmi.RemoteException

Registers the given external endpoint with the NMR. This indicates to the NMR that the given endpoint is used as a proxy for external service consumers to access an internal service of the same service name (but a different endpoint name).

Parameters:

externalEndpoint - the external endpoint to be registered, must be non-null.

Throws:

javax.jbi.JBIException - if an external endpoint with the same name is already registered, by this or another component.

java.rmi.RemoteException - impossible to realize a remote access

resolveEndpointReference

javax.jbi.servicedesc.ServiceEndpoint resolveEndpointReference(org.w3c.dom.DocumentFragment epr)
                                                               throws java.rmi.RemoteException

Resolve the given endpoint reference into a service endpoint. This is called by the component when it has an EPR that it wants to resolve into a service endpoint.

Note that the service endpoint returned refers to a dynamic endpoint; the endpoint will exist only as long as this component retains a strong reference to the object returned by this method. The endpoint may not be included in the list of "activated" endpoints.

Parameters:

epr - endpoint reference as an XML fragment; must be non-null.

Returns:

the service endpoint corresponding to the given endpoint reference; null if the reference cannot be resolved.

Throws:

java.rmi.RemoteException - impossible to realize a remote access
