To do a custom escalation in human task so when it a fixed duration expires it gets escalated to a different
user.
For that we need to write a java class that implements IDynamicTaskEscalationPattern interface
You need to place this class into oracle.bpel.services.workflow.assignment.dynamic package
Create a CustomEscalator
project
Make sure you select the below mentioned libraries
Create a class CustomEscalator that implements IDynamicTaskEscalationPattern
interface.
package oracle.bpel.services.workflow.assignment.dynamic;
import java.util.Collections;
import java.util.Locale;
import java.util.Map;
import java.util.Set;
import oracle.bpel.services.workflow.task.model.Task;
public class CustomEscalator implements IDynamicTaskEscalationPattern {
String user;
public CustomEscalator()
{
super();
System.out.println("***************default
constructor****************");
}
public String
getTaskEscalationUser(Task task) throws DynamicPatternException {
System.out.println ("***************getTaskEscalationUser**************");
System.out.println("Escalation User is "+user);
// task.setTitle("");
// String title="Escalated Task:
"+"User” +task.getOwnerGroup() +task.getTitle();
// System.out.println("Title
"+title);
// task.setTitle (title);
if (user!=null)
return user;
else
return
"testuser1";
}
public void
setInitParams(Map<String, String> map) throws DynamicPatternException {
System.out.println("**********setInitParams********************");
System.out.println(map);
String escalatedUser=map.get
("user");
System.out.println("Escalated UserName is "+escalatedUser);
user=escalatedUser;
}
public String getName() {
return
"CustomEscalator";
}
public String getLabel(Locale
locale) {
return null;
}
public String
getDescription(Locale locale) {
return null;
}
public
Set<IDynamicPattern.IDynamicPatternParameter> getPatternParameters() {
System.out.println("*******************getPatternParameters*****************");
return
Collections.emptySet();
}
}
Deploy this as a jar.
Now we need to place this jar into soa server but before
doing we will configure this escalation class through EM
Login to EM
Navigate to SOA-infra/SOA-Administration/Workflow-Properties
Click on Task
Click on add function
Function Name- CustomEscalator.
Classpath- oracle.bpel.services.workflow.assignment.dynamic.CustomEscalator.
We can also specify function parameter also but they are
optional
We can get these properties in our custom java class
Here for example I am setting an escalation username as ‘escalationUser’
in this function parameter but this user
should exist in weblogic realm.
Now we will set the customEscalation.jar to weblogic Classpath.
Navigate to C :\< Middleware Home> \Oracle_SOA1\soa\modules\oracle.soa.ext_11.1.1
Place this jar in this folder and run ant in this folder.
Restart the soa server after doing this.
Now go to human task deadline section and set escalation
after 3 minute for testing set Custom Escalation Java Class-CustomEscalation
Once this task get expires after 3 minutes it gets assigned to
escalated user.
