Type-Safe Access to BEA WebLogic Server 9.0 MBeans (Deprecated)

(Methods marked with @since 9.0.0.0 are not available through the deprecated MBeanHome interface.)

This bean represents the server-wide configuration of COM

Deprecation of MBeanHome and Type-Safe Interfaces

This is a type-safe interface for a WebLogic Server MBean, which you can import into your client classes and access through weblogic.management.MBeanHome. As of 9.0, the MBeanHome interface and all type-safe interfaces for WebLogic Server MBeans are deprecated. Instead, client classes that interact with WebLogic Server MBeans should use standard JMX design patterns in which clients use the javax.management.MBeanServerConnection interface to discover MBeans, attributes, and attribute types at runtime. For more information, see "Developing Manageable Applications with JMX" on http://www.oracle.com/technology/documentation/index.html.

7.0.0.0

Method Detail

getNTAuthHost

public String getNTAuthHost()

The address of the primary domain controller this server uses for authenticating clients. (If not specified, COM clients will not be authenticated.)

Returns:

The nTAuthHost value

isApartmentThreaded

public boolean isApartmentThreaded()

Controls the flag that is used to initialize COM in native mode.

By default, when jCOM initializes COM in native mode, it starts COM with the COINIT_MULTITHREADED. This causes COM to use Multi-Threaded Apartment (MTA) thread model. In the MTA model, calls to an object are not synchronized by COM. Multiple clients can concurrently call an object that supports this model on different threads, and the object must provide synchronization in its interface/method implementations using synchronization objects such as events, mutexes, semaphores, etc. MTA objects can receive concurrent calls from multiple out-of-process clients through a pool of COM-created threads belonging to the object's process.

If the server logs a Class Not Registered Message when starting COM in native mode, try setting this property. This will cause jCOM to start COM in native mode, using COINIT_APARTMENTTHREADED option instead of the COINIT_MULTITHREADED option. In a component that is marked as Apartment Threaded, each method of that component will execute on a thread that is associated with that component. This separates the methods into their own "Apartments", with each instance of a component corresponding to one apartment. While there is only one thread inside of a component, each instance of that component will have its own thread apartment.

Returns:

The apartmentThreaded value

Default value:

false

isMemoryLoggingEnabled

public boolean isMemoryLoggingEnabled()

Specifies whether this server should log memory usage.

Returns:

The memoryLoggingEnabled value

Default value:

false

isNativeModeEnabled

public boolean isNativeModeEnabled()

Specifies whether this server should use native DLLs to allow Java objects to interact with COM objects. (Supported on Windows only.)

Returns:

The nativeModeEnabled value

Default value:

false

isPrefetchEnums

public boolean isPrefetchEnums()

Specifies whether this server should prefetch the next element in a java.lang.Enumeration (that had been improperly converted from a COM VariantEnumeration type) so the correct value is returned when the hasMoreElements() method is called.

Some COM methods return a COM VariantEnumeration type. The java2com tool automatically converts the returned type into a java.lang.Enumeration. This is not a perfect match since COM enumerations have no equivalent to the hasMoreElements() call. The client must continue to call nextElement until a NoSuchElementException occurs. Setting this property will cause jCOM to prefetch the next element in behind the scenes and return the correct value when hasMoreElements is called.

Returns:

The prefetchEnums value

isVerboseLoggingEnabled

public boolean isVerboseLoggingEnabled()

Specifies whether verbose logging is enabled.

Returns:

The verboseLoggingEnabled value

Default value:

false

setApartmentThreaded

public void setApartmentThreaded(boolean b)

Parameters:

b - The new apartmentThreaded value
