Modifier and Type	Method	Description
java.lang.String	getNTAuthHost()	The address of the primary domain controller this server uses for authenticating clients.
boolean	isApartmentThreaded()	Controls the flag that is used to initialize COM in native mode.
boolean	isMemoryLoggingEnabled()	Specifies whether this server should log memory usage.
boolean	isNativeModeEnabled()	Specifies whether this server should use native DLLs to allow Java objects to interact with COM objects.

Method Detail

getNTAuthHost

java.lang.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

setNTAuthHost

void setNTAuthHost(java.lang.String host)

Sets the value of the NTAuthHost attribute.

Parameters:

host - The new nTAuthHost value

See Also:

getNTAuthHost()

isNativeModeEnabled

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

setNativeModeEnabled

void setNativeModeEnabled(boolean enable)

Sets the value of the NativeModeEnabled attribute.

Parameters:

enable - The new nativeModeEnabled value

See Also:

isNativeModeEnabled()

isVerboseLoggingEnabled

boolean isVerboseLoggingEnabled()

Specifies whether verbose logging is enabled.

Returns:

The verboseLoggingEnabled value

Default Value:

false

setVerboseLoggingEnabled

void setVerboseLoggingEnabled(boolean enable)

Sets the value of the VerboseLoggingEnabled attribute.

Parameters:

enable - The new verboseLoggingEnabled value

See Also:

isVerboseLoggingEnabled()

isMemoryLoggingEnabled

boolean isMemoryLoggingEnabled()

Specifies whether this server should log memory usage.

Returns:

The memoryLoggingEnabled value

Default Value:

false

setMemoryLoggingEnabled

void setMemoryLoggingEnabled(boolean enable)

Sets the value of the MemoryLoggingEnabled attribute.

Parameters:

enable - The new memoryLoggingEnabled value

See Also:

isMemoryLoggingEnabled()

isPrefetchEnums

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

setPrefetchEnums

void setPrefetchEnums(boolean enable)

Sets the value of the PrefetchEnums attribute.

Parameters:

enable - The new prefetchEnums value

See Also:

isPrefetchEnums()

isApartmentThreaded

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

setApartmentThreaded

void setApartmentThreaded(boolean b)

Sets the value of the ApartmentThreaded attribute.

Parameters:

b - The new apartmentThreaded value

isApartmentThreaded()
