Interface NamespaceManagementMBean

public interface NamespaceManagementMBean

The NamespaceManagementMBean interface defines methods for managing Rhino namespaces.

A namespace is a deployment environment isolated from every other namespace. It has its own independent set of installed deployable units and components, resource adaptor entities, profile tables, and environmental settings such as object pool configurations, security permissions, etc. A namespace also has its own SLEE activation state, so the components in a namespace can be started and stopped as if they were running in an independent SLEE.

Rhino always has a default namespace. User defined namespaces can be created and removed using the methods in this MBean.

Rhino 2.5.0

Method Detail

createNamespace

void createNamespace(String name)
              throws NullPointerException,
                     InvalidArgumentException,
                     NamespaceAlreadyExistsException,
                     ManagementException

Create a new user-defined namespace.

The namespace name must have at least one character. The names 'default' and 'global' (case insensitive) are reserved for internal use and cannot be used as the name of a user-defined namespace.

Parameters:

name - the name of the namespace to create.

Throws:

NullPointerException - if name is null.

InvalidArgumentException - if name is zero-length or a reserved name is specified.

NamespaceAlreadyExistsException - if a namespace with the specified name already exists.

ManagementException - if the namespace creation failed due to a system-level error.

Rhino 2.5.0

removeNamespace

void removeNamespace(String name)
              throws NullPointerException,
                     UnrecognizedNamespaceException,
                     InvalidStateException,
                     ManagementException

Remove a user-defined namespace.

All user-installed components and profile tables must be removed from a namespace before the namespace can be removed.

Parameters:

name - the name of the namespace to remove.

Throws:

NullPointerException - if name is null.

UnrecognizedNamespaceException - if name is not a recognised user-defined namespace name.

InvalidStateException - if user-installed components or profile tables still exist in the namespace.

ManagementException - if the namespace removal failed due to a system-level error.

Since:

Rhino 2.5.0

getNamespaces

String[] getNamespaces()
                throws ManagementException

Get the names of the user-defined namespaces that currently exist.

Returns:

the names of the user-defined namespaces.

Throws:

ManagementException - if the namespace names could not be obtained due to a system-level failure.

Since:

Rhino 2.5.0

setActiveNamespace

void setActiveNamespace(String name)
                 throws NoAuthenticatedSubjectException,
                        UnrecognizedNamespaceException,
                        ManagementException

Set the currently active namespace for the authenticated client connection. Future management operations will be applied to the specified namespace.

Each client connection thread is associated with its own active namespace. This means that if a client connection times out and reconnects and is handled by a different RMI connection thread, any previous active namespace association will be lost, and the client will need to reset the active namespace that it wishes to interact with.

Parameters:

name - the name of the namespace to set as active. May be null to indicate the default namespace should be made active.

Throws:

NoAuthenticatedSubjectException - if the current thread is not running with an authenticated Subject.

UnrecognizedNamespaceException - if name is not null and is not a recognised user-defined namespace name.

ManagementException - if the active namespace could not be set due to a system-level failure.

Since:

Rhino 2.5.0

getActiveNamespace

String getActiveNamespace()
                   throws NoAuthenticatedSubjectException,
                          ManagementException

Get the name of the currently active namespace.

Returns:

the name of the currently active namespace. A return value of null indicates that the default namespace is currently active.

Throws:

NoAuthenticatedSubjectException - if the current thread is not running with an authenticated Subject.

ManagementException - if the active namespace could not be obtained due to a system-level failure.
