A little more info.. I found that if I enclose the whole thing in a try
{}catch{}, then it seems to work, in spite of the exception.

I'm still not very comfortable using this with financial data, so any help
or insight about the exception would be appreciated :-)


  // returns 1=Sunday ... 7 = Saturday
  static public int dayOfWeek (long longDate) {
    int dayOfWeek = 0;
    try {
      GregorianCalendar cal = new GregorianCalendar((int)(longDate/10000),
(int)((longDate/100)%100)-1, (int)(longDate%100));
      dayOfWeek = cal.get(Calendar.DAY_OF_WEEK);         // 2=Monday
      }
    catch (Exception e) {}

    return(dayOfWeek);
  }

Weird.

I'm not sure if this will help, but I have never used "new 
GregorianCalendar(...)" for anything.  I always use 
"Calendar.getInstance(...)".  I'm not even sure why anymore... I'm sure 
there was some good API reason back in JDK 1.1 or 1.2.

I duplicated that line of code and had no trouble.  Upload the source
file to the borland.public.attachments group and I'll take a closer
look.

That's right. This is a well-known JVMDI (JVM debugging interface) bug 
in Java 1.4.x. There *is* a catch for this exception which is supposed 
to catch it, but JVMDI thinks it's uncaught.

Apparently the reason JVMDI fails is that there is a native routine on 
the stack between the throw and the catch, and it can't determine if 
that native routine will catch this exception or not, so it gives up and 
stops the process with an "uncaught" FileNotFoundException.  Even though 
there is a routine further down in the stack that *will* catch it.

When you continue, the exception is thrown and caught as usual.

Just grin and bear it, I guess. Not sure if JBuilder X or 2005 
non-foundation have options to ignore this "exception"..
