Hi Bart,
Thanks for the reply. I figured it out late yesterday. Maybe this will
help in the future.
One of the append() overloads of DateTimeFormatterBuilder takes an array
of DateTimeParsers and returns a DateTimeFormatter. The formatter runs
all of the parsers and selects the "best" (whatever that means) of the
parse results that do not fail.
Here is a snip of the code I wrote yesterday.
DateTimeFormatter fmt1 = DateTimeFormat.forPattern(dformat1);
//Lazard date time
//second format string is optional. If present we account for it
in the size of the DateTimeParser array passed to the
//DateTimeFormatterBuilder construtor below
DateTimeFormatter fmt2 = null;
DateTimeParser[] dtpa;
if(dformat2 == null || dformat2.length()==0)
{
dtpa = new DateTimeParser[1]; //need only 1 slot in the
parser array
}
else //the second format string exists
{
fmt2 = DateTimeFormat.forPattern(dformat2); //Lazard date time
dtpa = new DateTimeParser[2]; //need a parser array big enough
for the second format
dtpa[1] = fmt2.getParser();
}
dtpa[0] = fmt1.getParser();
//Try and parse using all parsers
DateTimeFormatter fmt = new
DateTimeFormatterBuilder().append(null, dtpa).toFormatter();
DateTime dt = fmt.parseDateTime(toBeFormatted);
Still pretty clunky and more lines than doing a catch on Illegal Arg
Exception but I'm willing to compromise for now. Sure beats writing a
custom parser line by line.
Also it may be worth going to a SimpleDateFormat object now that I know
that will handle this situation
Thanks again for your reply.

Don't miss this year's exciting event. There's still time to save $100.
Use priority code J8TL2D2.
