Title: RE: No Grammar Found Messages

Everyone:

I think I've determined what must be the problem here...

It seems that in Xerces 1.4.4 the feature for validating using schemas (http://apache.org/xml/features/validation/schema) was _true_ by default. In 2.x it is _false_ by default. DOM4J 1.4 doesn't set the feature on the reader so when I'm using DOM4J to get the reader, the reader is not configured to use XML Schemas. Therefore, no finding the DTD grammar would be expected.

Any suggestions for how to get around this? Can I set this feature for the entire JVM some how?

Is there any reason why this feature's default was changed? Wouldn't it make sense, nowadays, to just leave it true.

Thanks,

Brian

Hi Jeff,

Some more details...

I'm using an xsi:schemaLocation attribute set on the root element of the document. The location is an external reference to an HTTP server where the document is being stored.

===== Begin XML Snippet =====
<?xml version="1.0" encoding="UTF-8"?>

        <RenderingInformation>
                <Width>750</Width>
                <Height>300</Height>
                <Format>PNG</Format>
        </RenderingInformation>
.
.
.

===== End XML Snippet =====

I have validation turned on.

I am getting a reference to the SAXParser through DOM4J v1.4. So I'm creating an org.dom4j.io.SAXParser object and passing it true. I've confirmed that the SAX Parser implementation that DOM4J utilizes is the SAXParser from my Xerces-J 2.5 jar.

Interestingly enough, if I use Xerces 1.4 I don't have any problems. The XML document is successfully validated without any problems.

Thanks for yours and anyone else's help.

Brian

Hi Rick,
How do you bind your document instances to the Schemas? Are you using a
noNamespaceSchemaLocation or SchemaLocation?

Can you append at least a the first few line of your instance document?

More details would also help, are you validating? etc,
