Pre-requisites
- This sample uses Ruby, so first setup support for this in Synapse as described at Configuring JRuby
- Deploy the SimpleStockQuoteService in the sample Axis2 server and start Axis2
- Synapse does not ship with a Ruby engine by default. Therefore you should download the Ruby engine from JRuby site and copy the downloaded jar file to the 'lib' directory of Synapse.
-
Start Synapse using the configuration numbered 354 (repository/conf/sample/synapse_sample_354.xml)
Unix/Linux: sh synapse.sh -sample 354
Windows: synapse.bat -sample 354
