Prerequisites:

This sample uses Ruby, so first set up Ruby support as described at Configuring the ESB for Script Mediator Support.
Create the above configuration and deploy it in the ESB profile.
Start the Axis2 server and deploy the SimpleStockQuoteService if not already done

This sample is functionally equivalent to Sample 353.

Run the client with

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

Database Interactions in Mediation (DBLookup / DBReport)

Following database mediators use Derby in a client/server configuration by using the network server. Therefore, to proceed with the following samples, you need a working Derby database server and you have to follow the steps in ESB Sample Setup before going through the samples.
