when I try to concatenate a string within a JSTL tag. An error occur

Question

str += "<td><fmt:formatDate value='"+notices[i].noticeDuration+"' type='date' dateStyle='default' pattern='yyyy-MM-dd HH:mm' /></td>";

I am trying to concatenate a string, and append it to the body. Due to the JSTL tag---fmt, an error occurs. It said I lost a quotation. I tried to figure out why it happened, with no luck.

Like this, JSP compiler will see notices[i].noticeDuration as string as is, not date value. Because notices[i].noticeDuration run client (browser). So, you can't use JS variable in JSTL tags.
