<div class="jive-rendered-content"><p>I learned that the service task can be defined in a configuration file (see the following example), and added into the drools.rulebase.conf file (e.g., drools.workDefinitions = WorkDefinitions.conf abc.conf xyz.conf). It is obivous so far. To register a workitem handler for a service task, we use the following code: </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>ksession.getWorkItemManager().registerWorkItemHandler("Notification", new NotificationWorkItemHandler());</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Is there any way to register a workitem handler for a service task <span style="color: #ff0000; text-decoration: underline;"><strong>declaratively</strong></span> (e.g., using the configuration file)? Here is the reason why I ask this question. When a BPMN2 designer added a new service task and used it in a process flow, I don't want the user needs to change Java code for its registration. </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Example:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>  [</p><p>    "name" : "Notification",</p><p>    "parameters" : [</p><p>      "Message" : new StringDataType(),</p><p>      "From" : new StringDataType(),</p><p>      "To" : new StringDataType(),</p><p>      "Priority" : new StringDataType(),</p><p>    ],</p><p>    </p><p>     "results" : [</p><p>        "Result" : new StringDataType()</p><p>    ]</p><p>    </p><p>    "displayName" : "Notification",</p><p>    "icon" : "icons/notification.gif"</p><p>  ]</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Can we define a workitem handler here? Or, any other declarative way? So, the workitem handler can be automatically bound to the Notification Service Task without changing code.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Thanks,</p><p>bwj</p></div>
