Java EE (Java Enterprise Edition) General Discussion

I am having difficulties getting a custom tag library to work. I will explain what I've done so far and the errors I'm getting and hopefully somebody can enlighten me as to where I'm going wrong. I am using Tomcat version 3.2.1.
This is my first attempt at using taglibs so it's likely I am making a bonehead error, although I am following the instructions found in Hall's "Core Servlets and JSP" and the Tomcat development guide. Obviously I've done something wrong, but it's not obvious what that is.





I have a JSP which has the following lines of code in place to use my taglib:




<%@ taglib uri="/WEB-INF/errorMessages-taglib.tld"


prefix="errorMessages" %>


....





<errorMessages:message key="all" />








I have the taglib descriptor file under the web application's WEB-INF directory named errorMessages-taglib.tld and it looks like this:





-----------------


<?xml version="1.0" encoding="ISO-8859-1" ?>


<!DOCTYPE taglib


PUBLIC "-//Sun Microsystems, Inc.//DTD JSP Tag Library 1.1//EN"


"http://java.sun.com/j2ee/dtds/web-jsptaglibrary_1_1.dtd">


<taglib>


<tlibversion>1.0</tlibversion>


<jspversion>1.1</jspversion>


<shortname>errorMessages</shortname>


<urn></urn>


<info>A tag library to display error messages</info>


<tag>


<name>message</name>


<tagclass>dataview.taghandler.ErrorMessagesTagHandler</tagclass>


<info>Outputs an error message corresponding to the key provided, if present</info>


<bodycontent>EMPTY</bodycontent>


<attribute>


<name>key</name>


<required>false</required>


</attribute>


</tag>


</taglib>


------------------








I have included a <taglib> entry in my web.xml which looks like:





<taglib>


<taglib-uri>errorMessages</taglib-uri>


<taglib-location>/WEB-INF/errorMessages-taglib.tld</taglib-location>


</taglib>








I am getting a Jasper compile exception when I attempt to access the page, telling me that it can't open the tld and that I need to terminate a "description" element, even though there is no "description" element in the tld (see above). Below are the exception messages:








Internal Servlet Error:


org.apache.jasper.compiler.CompileException:


/var/tomcat/webapps/dataview/Select.jsp(8,4) Unable to open taglibrary


/WEB-INF/errorMessages-taglib.tld : Parse Error in the tag library descriptor: Next character must be ">" terminating element "description".

at org.apache.jasper.servlet.JasperLoader12.loadJSP(JasperLoader12.java)


..........








Can anybody see what it is that I'm doing wrong ? The exception message doesn't make any sense in the context (at least not to me). In any event I'm clueless as to how I might proceed, I've tried several different approaches (moving the tld to a different directory, using a different or no <taglib> entry in web.xml, etc.) but with no luck at all.





Thanks in advance for any suggestions or solutions.
