### Objective

Objective: Introduction to the payloadFactory mediator

### Pre-requisites

- Start the Synapse configuration numbered 17: i.e. synapse -sample 17
- Start the Axis2 server and deploy the SimpleStockQuoteService if not already done

### Executing the Client

Execute the client as follows.

ant stockquote -Daddurl=http://localhost:9000/services/SimpleStockQuoteService -Dtrpurl=http://localhost:8280/ -Dmode=customquote

This Sample demonstrates how the PayloadFactory Mediator can be used to perform transformations as an alternative to the XSLT mediator, which is demonstrated in Sample 8: Introduction to Static and Dynamic Registry Resources and Using XSLT Transformations
