Hallo,
I mailed this problem some time ago and Shawn Bayern answered to it, but I
didn't get it to work. So I try to explain my problem with some more details.
I'm using Tomcat 4b7. I tried to use datetime-TagLib, benchmark-TagLib and
jsptl-TagLib in one JSP-Page. But if I insert the 'jsptl' I get
the following Exception and I really didn't know why:
This is my jsp-Page:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<%@ page contentType="text/html" %>
<%@ taglib uri="http://jakarta.apache.org/taglibs/datetime"; prefix="dt" %>
<%@ taglib uri="http://jakarta.apache.org/taglibs/benchmark"; prefix="bm" %>
<%@ taglib uri="http://java.sun.com/jsptl/ea/jr"; prefix="jr" %>
<bm:duration output="true">
<html>
<head><title>JSP Testing</title></head>
<body>
<H1>JSP Testing Page</H1><BR>
Aktuelle Zeit: <FONT color='mediumblue'>
<dt:format pattern="EEEEE, dd.MMMMM.yyyy 'um' HH:mm:ss z">
<dt:currentTime/>
</dt:format></FONT>
<HR>
<BR><FONT color='red'>Working Time: </bm:duration> ms </FONT>
</body>
</html>
This is the exception I get:
