Class AbstractServiceDelegate

java.lang.Object

dev.dsf.bpe.v1.activity.AbstractServiceDelegate

All Implemented Interfaces:

org.camunda.bpm.engine.delegate.JavaDelegate, org.springframework.beans.factory.InitializingBean

public abstract class AbstractServiceDelegate
extends Object
implements org.camunda.bpm.engine.delegate.JavaDelegate, org.springframework.beans.factory.InitializingBean

Abstract implementation of the JavaDelegate interface with added error handling and convenient access to process execution variables with the variables parameter of the doExecute(DelegateExecution, Variables) method.

Configure BPMN service tasks with an implementation of type 'Java class' with the fully qualified class name of the class extending this abstract implementation.

Configure your service task implementation as a Bean in your spring Configuration class with scope "prototype".
