Custom Escalation in human workflow in SOA 11g

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.
