Taglib Import: xml Validation Errors with

Hi there,

I just started using FreeMarker to replace some of my JSP-Views
in my Spring Application and I am pretty impressed so far.

The only ugly thing I could find is an validation error when
using Taglibs. My Environment ist Spring 2.5, Tomcat 6.0.14,
FreeMarker 2.3.11. JRE6

My Import of the taglib in my Template looks like this:
<#assign c=JspTaglibs["http://java.sun.com/jstl/core_rt"] />

I guess it is not the standard way, most examples I found
use the "*.tld" path here, but this seems to work.

At view creation time I get the following validation Errors:

Warning: validation was turned on but an org.xml.sax.ErrorHandler was not
set, which is probably not what is desired.  Parser will use a default
ErrorHandler to print the first 10 errors.  Please call
the 'setErrorHandler' method to fix this.
Error: URI=jndi:/localhost/cms/WEB-INF/web.xml Line=6: Document root element "web-app", must match DOCTYPE root "null".
Error: URI=jndi:/localhost/cms/WEB-INF/web.xml Line=6: Document is invalid: no grammar found.

my web.xml starts like this and I am not sure what the validation
whining is about:

<?xml version="1.0" encoding="UTF-8"?>
<web-app id="blabla-System"
         version="2.4"
         xmlns="http://java.sun.com/xml/ns/j2ee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

    <display-name>blabla System</display-name>
[...]


So based on the opinion that i am smarter than the xml-validator, and that the
tlds in the jar file are correct I want to turn off xml-validation (somewhat
risky i know). Is there a way to use my own TaglibFactory, the default implementation
turns on the validation somewhere around line 370 as far as i understand the code,
setting the validation to off in this method should do the job ?

    private static void parseXml(InputStream in, String url, DefaultHandler handler)
    throws
        ParserConfigurationException, IOException, SAXException
    {
        InputSource is = new InputSource();
        is.setByteStream(in);
        is.setSystemId(url);
        SAXParserFactory factory = SAXParserFactory.newInstance();
        factory.setNamespaceAware(false);
        factory.setValidating(true);
        XMLReader reader = factory.newSAXParser().getXMLReader();
        reader.setEntityResolver(new LocalTaglibDtds());
        reader.setContentHandler(handler);
        reader.parse(is);
    }


I am open for any other suggestions to get rid of the ugly validation errors.


thanks & best regards
Michael
