What Is a Handler Service?

Chem eStandards Module Version 7.1.July 2008 | Installing and Using CHEM Module | Handling Errors and Exceptions | Handling Errors and Exceptions | What Is a Handler Service?

A handler service is a service that a particular step invokes when an event in the Chem eStandards process occurs. For example, in the Two Action Initiator Model.xml process model template, the Verify ACK step invokes the pub.estd.chem:verifyAcknowledgement service when the initiator receives a Receipt Acknowledgment (ACK) from the fulfiller.

In webMethods Developer, you create handler services by creating a new service for each event that you want to handle in a Chem eStandards conversation.
