Accessing Internet Explorer (IE) from Java

 Java/J2EE COM Interoperability Products Page

This example demonstrates how to access Internet Explorer (IE) from Java. J-Integra® for COM is a Java interoperability component that bridges Java and Internet Explorer (IE). It provides bi-directional access of Java objects and COM components.

We do not provide the documentation of the generated Java proxies since the Java proxies are just mapped from the programming API of the COM component. For more information about Internet Explorer programming, please refer to the Internet Explorer VB Reference.

This example is for IE 5.x. If you use a different version of IE, you need to look at the generated Java proxies and Internet Explorer programming API to call the methods accordingly.

Refer to the Excel example for details of steps.

/* This is an example of using J-Integra® to interface to Microsoft's Internet Explorer 5.x
 *
 * The program starts up an explorer application and registers an event listener which then
 * proceeds to record web navigations until the explorer window is closed. The java code
 * then also finishes.
 *
 * To run this example, create an 'ie' subdirectory, and run J-Integra®'s 'com2java'
 * tool, specifying the Internet Explorer type library (shdocvw.dll from the windows SYSTEM
 * directory - e.g. c:\WINNT\System or c:\WINDOWS\system32) as the input type library,
 * 'ie' as the package name, and the ie subdirectory you created as the output directory.
 *
 * This Java client will run on any machine which has a standard JVM, such as a UNIX machine.
 *
