RE: Maven Validator (maven-xhtml-plugin): Could not start validation: null not found

[Jeff Jensen <je...@upstairstechnology.com>]

FYI Follow up on solution/work around 

This problem does not occur on JDK 1.5, but does on 1.4, and on multiple of
my PCs and another person's.

We also found other people reporting similar issues (not related to using
Maven), but no resolution on the JDK problem yet.

So a workaround for anyone needing it and having this problem is to run
Maven with 1.5.

Subject: Maven Validator (maven-xhtml-plugin): Could not start validation:
null not found

(Is this the correct list for help on this plugin?  Its web page does not
have a list listed, it is not listed on sf's "Maven Plugins", but it is
hosted on sf, so I am not sure.)

I am using Maven beta 1.1 and trying to get the Validator "3rd party" plugin
working (maven-xhtml-plugin).

The following problem occurs:

Could not start validation: null not found at
org.apache.maven.xhtml.Validator.initValidator (Validator.java:176)

Has anyone seen this before?

The offending lines are:
        // turn validation on
        try
        {
            this.xmlReader = XMLReaderFactory.createXMLReader();
            this.xmlReader.setFeature(VALIDATION_FEATURE, true);
        }
        catch (SAXNotRecognizedException e)
        {
            throw new BuildException("Could not start validation: " +
this.xmlReader + " doesn't provide validation");
        }
        catch (SAXNotSupportedException e)
        {
            throw new BuildException("Could not start validation: " +
this.xmlReader + " doesn't provide validation");
        }
        catch (SAXException e)
        {
            throw new BuildException("Could not start validation: " +
this.xmlReader + " not found");
        }


So a SAXException was thrown, probably by
"XMLReaderFactory.createXMLReader()".

>From the Javadoc: "This method uses the value of the system property
"org.xml.sax.driver" as the full name of a Java class and tries to
instantiate that class as a SAX2 XMLReader."

I wonder if I have to set "org.xml.sax.driver" system property?

Or is there an extra config step I need to do that I did not see on the
plugin web site instructions?

Regretfully the real exception message is swallowed.  And before I have to
get source and modify and build to see it, I am hoping someone has a quick &
easy answer to the problem!  :-)
