The following code sample illustrates connecting to an Oracle Spatial database and adding custom reactors. Custom reactor declarations are in MyMapOracleReactors.h, one of the files included at the beginning of the sample. The "Subclassing Custom Reactors" sample shows what such a file would contain.
