Simple integration
IE automation sample
import com.jniwrapper.win32.automation.Automation; import com.jniwrapper.win32.automation.OleContainer; import com.jniwrapper.win32.automation.IDispatch; import com.jniwrapper.win32.automation.types.Variant; import com.jniwrapper.win32.ole.types.OleVerbs; import javax.swing.*; import java.awt.*; import java.awt.event.*; /** * This example demonstrates the embedding of Browser component into Java. */ public class IEAutomationSample extends JFrame { private OleContainer container = new OleContainer(); public IEAutomationSample() throws HeadlessException { super("Internet Explorer "); Container contentPane = getContentPane(); contentPane.setLayout(new BorderLayout()); contentPane.add(container); container.createObject("Shell.Explorer"); // Create Browser component by its ProgID final Automation webBrowserAutomation = new Automation(container.getOleObject()); webBrowserAutomation.invoke("Navigate2", new Object[]{"www.teamdev.com"}); Variant documentVariant = webBrowserAutomation.getProperty("Document"); IDispatch document = documentVariant.getPdispVal(); System.out.println("document = " + document.isNull()); this.addWindowListener(new WindowAdapter() { public void windowOpened(WindowEvent e) { // Show browser component, when parent widnow is shown container.doVerb(OleVerbs.SHOW); } public void windowClosing(WindowEvent e) { // Destroy the object when window is closed container.destroyObject(); } }); } public static void main(String[] args) throws Exception { final IEAutomationSample sample = new IEAutomationSample(); sample.setSize(800, 600); sample.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); sample.setLocationRelativeTo(null); sample.setVisible(true); } }
COM-to-Java integration
COM Interfaces & Data Types Wrappers
COM interfaces & data types wrappers allow working with COM types and interfaces like ordinary Java
objects. For example, you can use IUnknown, IClassFactory, and
IDispatch as typical Java interfaces, and
Variant(VARIANT), BStr(BSTR), SafeArray etc. as regular Java
types.
VTBL & COM Automation
ComfyJ allows invoking methods of a COM object via its function indexes in VTBL (Virtual Method Table), or by its names using the Automation approach. Also, Automation allows for obtaining and setting properties of a COM object, including indexed and named ones.
Support for Multiple Threading Models
ComfyJ provides a set of different concurrency models which you can use for initializing COM integration in your Java application.
DCOM Support
ComfyJ allows you to create a COM object on a remote server.
COM Memory Management
All COM and other native resources will be garbage-collected automatically, or you can release them if required by the application logic.
Embedding of OLE/OCX/ActiveX Components to Swing
ComfyJ includes the OleContainer Swing component, which allows you to:
- Use any visual COM component (OCX/ActiveX) in Java Swing UI. Using this functionality, you can embed various ActiveX applications, such as Internet Explorer, Acrobat Reader and Microsoft Office, as well as various media components such as Windows MediaPlayer, DVD Player, QuickTime, ShockwaveFlash, etc.
- Create an embedded object using
ProgID,CLSID, or from a document file. Also, you can insert a COM object (which implementsIOleObjectCOM interface) into container. - Save and load an embedded
OleObjectto or from a file in a special binary format.
Handling of COM Events
ComfyJ provides a standard COM technique for creating and advising COM event handlers to a COM object.
CodeGenerator utility
With this bundled application, you can generate Java COM wrappers for COM components or COM Type Libraries. These generated classes allow you to work with COM objects just like regular Java objects. Moreover, this application can compile the generated classes and pack them into a JAR file, if needed.
Java-to-COM integration
This aspect of ComfyJ allows you to create Java COM servers purely in Java. In other words, a designed Java COM server can be exposed as COM objects to other COM applications without writing a line of a native code.
Development of Java COM Servers
To simplify creation of custom Java COM servers, ComfyJ provides the base classes such as IUnknownServer
and IDispatchServer so any custom Java COM objects can inherit these classes, depending on
application requirements. Such Java COM servers can implement as many COM interfaces as required—from
standard COM interfaces and COM interfaces generated by ComfyJ's Code Generator application, to custom
ones.
Registration of Java COM Servers
ComfyJ also provides convenient ways for registering created Java COM servers. Such registration can be performed at runtime, i.e., for COM event handlers, or in COM Registry using a bundled ServerManager application. Also, you have the ability to register Java COM servers at runtime without using the ServerManager application. Such registered Java COM servers can be used by other COM applications.

Frequently asked questions
Technical Questions
Is it possible to integrate with a .NET component using ComfyJ?
It is possible only if that .NET component is built with enabled COM interop.
What does the AutoDelete property of the IUknown interface mean?
This property instructs ComfyJ's NativeResourceCollector (NRC) whether to release the COM object automatically or not. By default, this property is set to true for all resources that implement AutoDeleteParameter interface. When this property is set to false, the .release() method should not be called.
How to query a required COM interface from a COM object in ComfyJ?
A required COM interface can be queried using the IUnknown.queryInterface() method, for
example:
IOleObjectImpl oleObject = new IOleObjectImpl();
comObject.queryInterface(oleObject.getIID(), oleObject);
Or
IOleObjectImpl oleObject = new IOleObjectImpl(comObject);
Can I use ComfyJ in Java applet?
Yes, ComfyJ can be used in Java applets. There are several examples in ComfyJ distribution archive, in its samples\Applets\src\ subfolder, which demonstrate using of ComfyJ in Java applets.
Can I release a COM object?
Yes, every COM object can be released using its IUnknown#release() method. Make sure to set its AutoDelete property to false before releasing the object.
Does ComfyJ provide the ability to embed an ActiveX component to a Java window?
Yes, ComfyJ provides OleContainer Java component that allows embedding of any ActiveX component.
Where should I put my ComfyJ license files (jniwrap.lic, comfyj.lic)?
The simplest way is to package these files to the \META-INF\ subdirectory of an application JAR file.
How I can redistribute native JNIWrapper library (jniwrap.dll, jniwrap64.dll, etc.) with my application?
The simplest way is to package all required JNIWrapper library files to root folder of an application JAR file.
When I invoke method of a COM object, it throws
COM exception: COM object method returns error code:
0x800401F0; CO_E_NOTINITIALIZED
COM should be initialized using ComFunctions.coInitialize() method in each Java thread (except OleMessageLoop) before working with COM objects.
Is it possible to expose Java object to COM using ComfyJ?
Yes, ComfyJ provides the ability to create Java COM servers and register them in COM.
How do I configure the license?
Take a look at the license installation instruction.
