(WID/WPS) Configuring EventHandler for an Escalation (WPS)

If an escalation occurs during the execution of a human task, you may want to notify an event handler within the application environment.

To configure an event and add it to your business application model, follow these instructions.

Declare a notification event handler for your task as described here:

• In the human task editor click the Details tab. 
• In the Event handler name field, enter a name for your notification event handler. {This name is not the name of the implementation class.}
• Click Save. 

Add your plugin to your application:

• Switch to the Resource perspective. 
• In the Navigator, expand your business integration project. 
• In the META-INF folder, create a new folder services. 
• Right-click the services folder and select New > File . 
• In the File name field of the New File wizard, , enter com.ibm.task.spi.EventHandlerNameNotificationEventHandlerPlugin Where EventHandlerName is the event handler name you have specified for your task. 
• Click Finish. 
• In the above file, write the fully qualified name of the event handler class.(For example : bpc.samples.plugin.EscalationNotificationPlugin)

Implementing the Event Handler Class:

EscalationNotificationPlugin.java

package bpc.samples.plugin;

import com.ibm.task.api.Escalation;

import com.ibm.task.api.TKIID;

import com.ibm.task.api.Task;

import com.ibm.task.spi.NotificationEventHandlerPlugin;

public class EscalationNotificationPlugin implements

NotificationEventHandlerPlugin {

public void escalationNotification(Task task, Escalation escalation) {

System.out.println("Entering method");

if(task != null && escalation != null)

{

System.out.println("Task template name: " + task.getTaskTemplateName());

System.out.println("Task name: " + task.getName());

System.out.println("Task state: " + task.getState());

System.out.println("Event handler name: " + task.getEventHandlerName());

System.out.println("Is escalated: " + task.isEscalated());

System.out.println("Escalation name: " + escalation.getName());

TKIID tkId = task.getID();

System.out.println("Task Id : " + tkId);

}

}

}

Specify an escalation with a notification type Event:

• Switch to the Business Integration perspective and open your task in the human task editor. 
• In the Escalation settings section, select the escalation. 
• Click the Details tab. 
• Configure the escalation as needed. For Notification type, choose Event from the list of available options. 
• Save your work.
