Ellipsis (shortened text) with JSP / EL

I was wondering what is the best way to implement the ellipsis abbreviation with JSP / Expression Language.

I am currently using fn: substring, which is good, but I would like to have three dots "..." if the text was truncated.

Using web search, I found that the Java web part has an AbbreviateTag . However, I was wondering if there are better libraries, or if it is better, I translate my own tag. What are you offering?

<p><sti:ellipsis maxLength="10">What a beautiful day.</sti:ellipsis></p>

:

What a beautiful day.

</c:if>
<c:out value="${colTxt}" />
