Create java: error reporting

Question

Hey all,
Does anyone have any suggestions for how to receive more specific error messages from the compilation of java sources through sql statements? For example, I just tried compiling a piece of code and received the following error message:
ORA-29511: could not resolve Java class
I'm not surprised that I received the error, but it's a little inconclusive.
Any ideas?
Thanks,
Jonathan

Umm.....so....I just realized this may actually be a problem with the HTML DB interface. I had assumed it would transparently pass db error messages to the front-end. -_-;;
I'm actually having trouble replicating this error now. Right now, when I try the following three commands I receive the following replies:
1) Statement processed.
2) Function created.
3) ORA-29541: class ARDB.CalendarInterface could not be resolved
The 'create java' statement should be returning a 'cannot find class' error.
Hmm.....excuse the long post.

create or replace and compile java source named "CalendarInterface" as
import oracle.calendar.soap.client.CalendaringResponse;
import oracle.calendar.soap.client.Calendarlet;
import oracle.calendar.soap.client.CreateCommand;
import oracle.calendar.soap.client.authentication.BasicAuth;
import oracle.calendar.soap.iCal.iCalendar;
import oracle.calendar.soap.iCal.vCalendar;
import oracle.calendar.soap.iCal.vEvent;
public class CalendarInterface
  public static int addEvent(String title, String description, String dtStart, String duration)
       iCalendar ical   = new iCalendar();    
       vCalendar vcal   = new vCalendar();
       vEvent    vevent = new vEvent();
       ical.addvCalendar(vcal);
       vcal.addvComponent(vevent);
       String uid     = "ARDB-TEST-2";
       vevent.setEventClass(vEvent.k_eventClassPublic);
       // dtStart format: "yyyymmddThhmmssZ"
       vevent.setDtStart(dtStart);
       // Duration format: "PThhHmmM"
       vevent.setDuration(duration);
       vevent.setLocation("HQ");
       vevent.setSummary(title);
       vevent.setUid(uid);
       vevent.setXEventType(vEvent.k_eventTypeAppointment);
       vevent.setDescription(description);
       CreateCommand create = new CreateCommand();
       create.setCmdId("test");
       create.setiCalendar(ical);
       Calendarlet cws = new Calendarlet();      
       BasicAuth auth = new BasicAuth();
       auth.setName("username");
       auth.setPassword("password");
       cws.setEndPointURL("url");
       cws.setWantIOBuffers(true);
       cws.setAuthenticationHeader(auth.getElement());
       try {
          CalendaringResponse response = cws.Create(create.getElement());
       } catch (Exception ex)
         System.out.println("There was an error while retrieving a response from the Calendar server.");
       return 1;
CREATE OR REPLACE FUNCTION addEvent (
   title IN VARCHAR2,
   description IN VARCHAR2,
   dtStart IN VARCHAR2,
   duration IN VARCHAR2)
   RETURN NUMBER
AS LANGUAGE JAVA
   NAME 'CalendarInterface.addEvent (
            java.lang.String,
            java.lang.String,
            java.lang.String,
            java.lang.String)
            return int';
declare
  retval   number;
begin
  retval := addEvent('Title', 'Description', '20050817T100000Z', 'PT01H00M');
  htp.p(retval);
end;
