### Objective

Invoke Secured Services with Scheduled Message Forwarding Processor

### Pre-requisites

- Download and install the Java Cryptography Extension (JCE) unlimited strength policy files for your JDK
- Start Synapse using the configuration numbered 704 (repository/conf/sample/synapse_sample_704.xml)
  Unix/Linux: sh synapse.sh -sample 704
  Windows: synapse.bat -sample 704

### Executing the Client

Execute the sample client a few times with the following command. Note that we still haven't started the sample Axis2 server.

ant stockquote -Daddurl=http://localhost:8280/ -Dmode=placeorder

Deploy the SecureStockQuoteService in the sample Axis2 server and start Axis2.

When you start the service you will see messages getting delivered to the service, even though the service was actually down when we invoked the sample client.

Here in the 'main' sequence, store mediator will store the placeOrder request message in the 'MyStore' message store. Message processor will send the message to the secured backend service using the defined endpoint. Endpoint is configured to use WS-Security. Message processor will remove the message from the store only if the message is delivered successfully.
