jstl function to get right customer number

[GoSooJJ]

I have a customer number as 000-000000-000000. I'd like to have if statement that check for length is 17 and first 3 digits are number and 5-11 is number and 13-17 is number. I'm very new to jsp 2.0 and willing to convert my coldfusion to jsp page by using jstl tag.
Can someone help me on this?

thank you.

perfect task for Regular Expressions

adjust to a pattern of something as
[\d]{3}(-)[\d]{6}(-)[\d]{6}

ok, now i'm facing how to use this in jstl page. here is my code.

<c:choose>
<c:when test=&quot;${not empty param.cid}&quot;>
<c:set var=&quot;cidFormat&quot; value=&quot;[\d]{3}(-)[\d]{6}(-)[\d]{6}}&quot; />
<c:choose>
<c:when test=&quot;${param.cid.match(cidFormat)}&quot;>
good cid
</c:when>
<ctherwise>
bad cid
<%--<c:redirect url=&quot;error.jsp&quot; />--%>
</ctherwise>
</c:choose>
</c:when>
<ctherwise>
<%--<c:redirect url=&quot;error.jsp&quot; />--%>
</ctherwise>
</c:choose>

of course, i'm getting an error that &quot;The function match must be used with a prefix when a default namespace is not specified&quot;. I do not know how to plug in. It's really hard to find any examples from web since jstl is pretty new...

there's a extra } in there
=&quot;[\d]{3}(-)[\d]{6}(-)[\d]{6}}&quot; <--

to
=&quot;[\d]{3}(-)[\d]{6}(-)[\d]{6}&quot;

I'll take a look at the complete in a sec if someone else does not
