JACOB 1.11

What's New

• Build
  • Build process now notifies developer if version property missing
  • Build process now compiles 32 bit and/or 64 bit DLLs as appropriate for the build environment.
• API Changes
  • Variant.noParam() changed to Variant.putNoParam()
  • Variant.toString() now follows normal java semantics. This conflicted with the jacob toXXX() standard.
  • Many Variant.toXXX() did type conversion in addition to a get. The methods have deprecated because folks didn't realize they were doing type conversion. Most calls to toXXX() methods should actually be getXXX() calls. This also allowed toString() to follow Java conventions
  • Variant native methods are wrapped with java methods that do parameter and state checking to better armor the Variant

Tracked Changes

JACOB 1.10.1

What's New

• Variants
  • Static constnats are no longer released
  • obj2variant on Dispatch now supports passing a java.util.Date

Tracked Changes

JACOB 1.10

What's New

• Windows Processes
  • New proposed API to support ActiveXComponent connections to already running applications. Factory methods have been added to the ActiveXComponent to support this. (Feedback wanted)
• Variants
  • Variant now accept Java Dates in the constructor.
  • Redundant constructors removed
  • Experimental toJavaObject() method added that automatically converts to appropriate java type
  • Support added for "NOTHING", a Variant of type Dispatch with no value
  • Non functional getNull() and getEmpty() methods deprecated. They were void methods
• Event Callbacks
  • Jacob normally uses information in the registry to find the connection information needed to set up event callbacks. Excel and other programs don't put that information in the registry. A new optional parameter has been added to the DispatchEvents constructors that lets a user provide the location of the OLB or EXE that contains the information required to retrieve the events.
  • Event handlers can now return a Variant to calling MS Windows program. Event handlers that do not return an object should still be defined as being of type "void". This means that support for event handler's returning values should be backwards compatible with previous releases.

Tracked Changes

JACOB 1.9.1

What's New

• License
  • License standardized on LGPL. See LICENSE.TXT for more information
• Event Callbacks
  • Event handlers are now wrapped in an InvocationProxy. The COM/JNI event code knows only about InvocationProxies and calls the appropriate methods on the Invocation proxy to get needed Variant instances and to forward events to the Java layer.
• Variants
  • Automatic conversion between Windows Time and Java Date is now supported in Variant object.
• SafeArray
  • Multi-dimensional (greater than 2) support

Tracked Changes

JACOB 1.9

What's New

• Event Callbacks
  • Variant parameters can now be modified by the receiver to be passed back to the COM caller
  • Callbacks now create objects of class VariantViaEvent rather than Variant. This was aided to add debugging and tracing
  • Callbacks can now be received when running in JWS other launchers where JACOB.jar is not in the system classloader's path.
• Dispatch API Clarifications
  • All static method's first parameters have been more strongly typed to the Dispatch class, rather than Object. This may call for code changes in the cases of code that just asigned Dispatch objects to variables of type Object rather than Dispatch or one of its subclasses
• Dispatch subclasses are now supported with pointer modifying constructor
  • Dispatch and ActiveXComponent now includes a constructor to be used by Dispatch subclasses that swaps the pointers around. This eliminates the need for every Dispatch subclass to have a constructor that swapped and nulled out the pointers to the COM layer. All samples have updated to use the new api
• ActiveXComponent has been upgraded
  • ActiveXComponent methods return ActiveXComponets
  • Methods have been added to the ActiveXComponents to retrieve parameters as Dispatch objects or ActiveX components. The Script Tests have been updated to show the same programs in Dispatch format or ActiveXComponentFormat
• Memory Management
  • Beta test option that lets an application use automatic object object removal through the use of weak reference hash maps in the ROT class.  The default behavior of manual release via the COMThread class has been retained as the default behavior.  Developers can test automatic memory collection by using the command line option -Dcom.JACOB.autogc=true
• JNI Changes
  • Erroneous Array dimension checking fixed for certain boolean set and get functions
  • Alternative method for finding Variant class for callbacks in JWS or other application lanchers where the system classloader does not know about JACOB classes.
  • Unicode is supported for putString and putStringRef
  • EventProxy zeros out the com object reference in the Variant objects that are created by EventProxy so that they are not double released, by both the Java VM and calling code from the COM side. The caller is supposed to be responsible for releasing the memory it created. This fix only applies to Variants created in callbacks.
• Logging Additions
  • Debugging logging to standard out for JACOB can be turned on by using the command line option -Dcom.JACOB.debug=true
• Visual Studio
  • The VisualStudio directory in the CVS repository will be removed in the next release
• Documentation
  • API documentation via Javadoc  is now being generated for all classes.
  • The development team is looking for help in upgrading the quality of the class documentation
• Build Changes
  • A static method has been added to JacobObject that returns the build version
  • The project is now being built using ANT.  Most of the developers are running this from inside of Eclipse
  • All makefiles have been purged

JACOB 1.8

What's New

• Move To SourceForge The project is not housed at Sourceforge.net.
• Licensing Change All limitations on commercial use of JACOB have been removed and it is now being developed under a BSD license at Sourceforge.net.
