[XQZone General] JSP Tag library question

Thu May 12 12:23:51 PDT 2005

I placed MLXQueryTaglib.jar file under the lib folder and copied the
marklogicxquery.tld file in my WEB-INF and defined the entry in my
web.xml file still no luck
<taglib>
        <taglib-uri>http://marklogic.com/jsp/taglib</taglib-uri>
        <taglib-location>/WEB-INF/marklogicxquery.tld</taglib-location>
</taglib>

It gives me the following error. 
javax.servlet.ServletException: com/marklogic/xqrunner/XQException

here is my jsp code, the XdbcServer is running on port 9061. Cant figure
out what's wrong.

<%@ taglib uri="http://marklogic.com/jsp/taglib" prefix="xq" %>
<xq:setDataSource host="localhost" port="9061"
   user="edmunds" password="rdf"/>
<html>
	<head>
		<title>xq:query example 1</title>
	</head>
	<body>
	My favorite fruits:
	<ul>
	<xq:execute>
	   <xq:query>
	       for $i in ("apple", "pear", "orange", "guava")
	         return <li>{ $i }</li>
	   </xq:query>
	/xq:execute>
	/ul>
</body>
</html>

BTW, I am using Tomcat
Thanks
Rashid

    That's progress.  It means the web container knows
which classes to use for the tags.

    The error you're seeing indicates the container can't
find the classes in the jar file.  Double check that
MLXQueryTaglib.jar is in WEB-INF/lib under your web
app and that it's readable.

    It may require re-deploying your web app, or even
restarting, depending on the container you're using.

    Use the .war file including in the JSP distribution
as a guide if you're still having trouble.
