I’d like to develop a java program to get JDBC Conneciton Statistics. I found a built-in service, pub.art.connection:getConnectionStatistics. Is there any sample program to show how to invoke built-in services?
please have a look at the IntegrationServer Built-In-Services Reference, which has a description of most of the bult-in services, and the Service Development Guide, which describes how to develop services.
There are other Built-In-Services references available for other components like Monitor or TradingNetworks.
You can search the samples & download sections of the TechCommunity to check if there is a sample which matches your needs.
