String getNTAuthHost()
The address of the primary domain controller this server uses for authenticating clients. (If not specified, COM clients will not be authenticated.)
void setNTAuthHost(String host)
Sets the value of the NTAuthHost attribute.
host
- The new nTAuthHost valueCOMMBean.getNTAuthHost()
boolean isNativeModeEnabled()
Specifies whether this server should use native DLLs to allow Java objects to interact with COM objects. (Supported on Windows only.)
void setNativeModeEnabled(boolean enable)
Sets the value of the NativeModeEnabled attribute.
enable
- The new nativeModeEnabled valueCOMMBean.isNativeModeEnabled()
boolean isVerboseLoggingEnabled()
Specifies whether verbose logging is enabled.
void setVerboseLoggingEnabled(boolean enable)
Sets the value of the VerboseLoggingEnabled attribute.
enable
- The new verboseLoggingEnabled valueCOMMBean.isVerboseLoggingEnabled()
boolean isMemoryLoggingEnabled()
Specifies whether this server should log memory usage.
void setMemoryLoggingEnabled(boolean enable)
Sets the value of the MemoryLoggingEnabled attribute.
enable
- The new memoryLoggingEnabled valueCOMMBean.isMemoryLoggingEnabled()
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.
void setPrefetchEnums(boolean enable)
Sets the value of the PrefetchEnums attribute.
enable
- The new prefetchEnums valueCOMMBean.isPrefetchEnums()
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.
void setApartmentThreaded(boolean b)
Sets the value of the ApartmentThreaded attribute.
b
- The new apartmentThreaded valueCOMMBean.isApartmentThreaded()
