Yes, starting with RootCause version 2.1.3a (April 2004). There are two parts: • In the deployment descriptor XML file, indicate that the parameters are read/write (not the default of read-only): • In the probe itself, simply assign new Objects to the params vector: import com.ocsystems.aprobe.*; public class TestParamsProbe extends ProbeMethod { public boolean onEntry (Object[] params) { // params [0], the ‘this’ parameter, can’t and won’t be changed. params [1] = new String (“This is a new string”); params [2] = new Boolean (true); return true; } public Object onExit (Object returnValue) { int value = ((Integer) returnValue).
