<h2>Using various JSTL 1.1 functions</h2>
<c:set var="tempStr" value="I love Java an www.java2s.com"/>
The length of the test String: ${fn:length(tempStr)}<br />
Does the test String contain "test"? ${fn:contains(tempStr,"test")}<br />
Putting the String into upper case using fn:toUpperCase(): ${fn:toUpperCase(tempStr)}<br />
Splitting the String into a String array using fn:split(), and returning the array length: ${fn:length(fn:split(tempStr," "))}<br />
