title: eclipse jsp the function fn:escapeXml is undefined
body: <p>I am beginning my first google app engine jsp project. I am following the tutorial for the guestbook from here: <a href="https://developers.google.com/appengine/docs/java/gettingstarted/introduction" rel="noreferrer">https://developers.google.com/appengine/docs/java/gettingstarted/introduction</a>. I am on the datastore step ( <a href="https://developers.google.com/appengine/docs/java/gettingstarted/usingdatastore" rel="noreferrer">https://developers.google.com/appengine/docs/java/gettingstarted/usingdatastore</a> ) and have pasted in the code on that page directly into my project. The code compiles and works, but I get the red squiggly underlines under fn:escapeXml calls. I see that these are functions from a taglib, as explained here: <a href="http://www.tutorialspoint.com/jsp/jsp_standard_tag_library.htm" rel="noreferrer">http://www.tutorialspoint.com/jsp/jsp_standard_tag_library.htm</a> . So, how do I make eclipse know what is going on and not think this is an error?</p>
