Hi Java gurus,

I have been trying to get "proper" java logging (using java.util.logging) to work from an agent. I have posted simplified test code below.

When I run the agent, there are no exceptions, but no logging either. Following suggestions discovered on-line, I have modified {Notes}\jvm\lib\security\java.policy and {Notes}\Data\workspace\.config\rcpinstall.properties with no sucess. (Aside: the need to modify these files makes this whole logging method a non-starter for us, but I wanted to at least get this working.)

I admit that I am still climbing the learning curve, but, it looks like we will need to write our own logging.

Thanks for any help.

import java.util.logging.*;

public class JavaAgent extends AgentBase {

// Taken from http://www-10.lotus.com/ldd/lewiki.nsf/dx/Java.util.logging_best_practices_XPD622
private static final String CLAZZ_NAME = JavaAgent.class.getName();
// private static final String PKG = JavaAgent.class.getPackage().getName(); // returns null for the agent's "(default package)".
// private static Logger _logger = Logger.getLogger(PKG);
private static Logger _logger = Logger.getLogger(CLAZZ_NAME); // used CLAZZ_NAME instead of PKG, which is null.

public void NotesMain() {
final String METHOD = "NotesMain";
_logger.entering(CLAZZ_NAME, METHOD);

try {
Session session = getSession();
AgentContext agentContext = session.getAgentContext();

_logger.logp(Level.FINE, CLAZZ_NAME, METHOD, "User: " + session.getEffectiveUserName());

DateTime lastRun = agentContext.getLastRun();
if (lastRun == null) {
_logger.logp(Level.FINE, CLAZZ_NAME, METHOD, "Last Run (GMT): " + "[never]");
} else {
_logger.logp(Level.FINE, CLAZZ_NAME, METHOD, "Last Run (GMT): [" + lastRun.getGMTTime() + "]");
}

_logger.logp(Level.FINER, CLAZZ_NAME, METHOD, "Calling someWork");
this.someWork(1);

_logger.logp(Level.FINER, CLAZZ_NAME, METHOD, "Back from someWork");

} catch (Exception e) {
// _logger.logp(Level.SEVERE, CLAZZ_NAME, METHOD, "Caught exception", e);
e.printStackTrace();
}
_logger.exiting(CLAZZ_NAME, METHOD);
}

private void someWork(int value) {
final String METHOD = "someWork";
_logger.entering(CLAZZ_NAME, METHOD, new Integer(value));
_logger.logp(Level.INFO, CLAZZ_NAME, METHOD, Integer.toString(++value));
_logger.exiting(CLAZZ_NAME, METHOD);
}
}
