Apache Synapse - Sample 363
lookupdb select * from company where name =?
reportdb update company set price=? where name =? reportdb select * from company where name =? ]]>

Demonstrate how to setup reusable connection pools for the dblookup and dbreport mediators

  • Setup a Derby database and the Synapse data sources as described in the database setup guide
  • Deploy the SimpleStockQuoteService in the sample Axis2 server and start Axis2
  • Start Synapse using the configuration numbered 363 (repository/conf/sample/synapse_sample_363.xml)
    Unix/Linux: sh synapse.sh -sample 363
    Windows: synapse.bat -sample 363

This sample employs two instances of the dblookup mediator and a single instance of the dbreport mediator. The two dblookup mediators are sharing the same database connection pool named 'lookupdb'. The dbreport mediator makes use of a different connection pool named 'dbreport'. Synapse uses Apache DBCP to create and manage the corresponding data sources and connection pools.

Run this sample by invoking the client as follows.

ant stockquote -Daddurl=http://localhost:9000/services/SimpleStockQuoteService -Dtrpurl=http://localhost:8280/ -Dsymbol=IBM

Synapse will log the following output as it reads from and writes to the database.

INFO LogMediator text = ** Looking up from the Database ** ... INFO LogMediator text = Company ID - c1 ... INFO LogMediator text = ** Reporting to the Database ** ... INFO LogMediator text = ** Looking up from the Database ** ... INFO LogMediator text = Stock price - 183.3635460215262
