How to Send a Task Item

 

The following Java code shows how to create and send a task item using CDO and J-Integra for Exchange. For more information on CDO Type property fields, refer to
CDO Object Model.

import com.intrinsyc.cdo.*;
import java.util.Date;

public class SendTaskRequest {

    // Modify the following variables based on your specific setup
    // domain where the CDO host machine belongs, make sure it's all capitalized
    static String domain = "DOMAIN";
    // Java-Exchange username
    static String user = "username";
    // password of Java-Exchange user
    static String password = "password";
    // mailbox of Java-Exchange user
    static String mailbox    = "mailbox";
