Thanks this helped a lot. I'd already grimbled over
several books on these subjects.
Re: fmt tags...
It must have been my error... but I must have been trying
to do the format in one step. After posting my earlier
message I tried again... having just looked over all I
was trying to do this sometimes helps... anyway this
example does work, and does exactly what I had been
trying to do!
<fmt:parseDate var="date" value="${rows.STARTDATE}"
pattern="yyyyy-MM-dd kk:mm:ss.SSS"/>
<fmt:formatDate value="${date}" pattern="MMM d, yyyy"/>
I needed to use both fmt steps, like I said, I must have
previously tried getting it done in one step.
Thanks again
Roy
