I would like to use the fmt jstl taglib in a JSP page to format and display a phone number. I would rather not format it in an Java action class or another class. I have received the advice to use the fmt jstl taglib but I do not see how a phone number can be formatted with any of its tags. Maybe it's not an option. Has anyone done this before? Thanks.
The phone number originally looks like: 5555555555 and I want to reformat it to 555-555-5555.
Not the JSTL <fmt> tags won't help you here. They can only handle number/date formatting. They are written as a tag interface to the java.text packages for NumberFormat and DateFormat. Neither of those classes will help you with formatting a telephone number. I would probably go with - a custom tag - a static method to do the formatting, and call it via an EL function (JSP2.0)
Either way, some java code will have to be written.
