Accessing Microsoft Outlook from Java

 Java/J2EE COM Interoperability Products Page

This example demonstrates how to access Microsoft Outlook from Java. J-Integra® for COM is a Java interoperability component that bridges Java and Microsoft Outlook. 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 Microsoft Outlook programming, please refer to the Microsoft Outlook VBA Language Reference. The quickest way to start programming Java-to-Outlook is to find a VB example first, and then map the VB example to Java.

Refer to the Excel example for the details of steps.

/* This example is for Outlook XP and lists all the items in the outlook Journal folder.
 *
 * It assumes that the 'com2java' tool has been run on the Outlook type library
 * C:\Program Files\Microsoft Office\Office10\MSOUTL.OLB
 * and that the pure Java files that were generated are in a subdirectory called 'outlook'
