I am currently busy developing a JMX interface for WebSphere 6.1. I am using AdminClient to manage the capabilities. When looking for a datasource, I use the following query string
String queryDSRC = "WebSphere:*,type=DataSource,j2eeType=JDBCDataSource";
which returns a Set. I can then access the returned objects. As I want to get the status of the datasource, I need to use the getStatus method of the DataSource MBean. I can see a definition in the WebSphere documentation, (Reference Mbean interfaces), but this does not include the full classname.
