### Objective

Showcase how to use a predefined set of static subscriptions with Synapse

### Pre-requisites

- Deploy the SimpleStockQuoteService in the sample Axis2 server and start Axis2
- Start Synapse using the configuration numbered 501 (repository/conf/sample/synapse_sample_501.xml)
  Unix/Linux: sh synapse.sh -sample 501
  Windows: synapse.bat -sample 501

### Executing the Client

In this sample configuration, two static subscriptions are created by providing the SimpleStockQuoteService as the event sink. To try this out, invoke the sample client as follows.

ant eventsender

Events will be mediated and sent to the sample Axis2 server as operated by the two static subscriptions.
