I setup the entity resolver to look for the system id that you would have seen if you put in the XML instance document the schema information. This is how I do my XSD schema validation. BTW, I could only use Xerces to properly validate my schema, others just did not work correctly.
Hope that helps, Dave

Hi Dave,
I did what u said but still i get the same error..
Actually Im trying to validate against a Schema...but it seems to be looking for DOCTYPE....I thought DOCTYPE is only required for validating against dtds... Am i right?
I put the following in my xml <!DOCTYPE eventNotificationMsg SYSTEM "EventNotification_06232003.xsd">
then the DOCtype error goes away, but i get another error.. [java] <fatalError column="3" line="1">The markup declarations contained or pointed to by the document type declaration must be well-formed.</fatalError>
It seems to be looking for a DTD and not a schema... How do I tell the parser that I want to do a Schema validation (not DTD validataion)??

You xml instance needs to define what schema it is using. Apparently there is nothing handling the "null" schema.
Try something like:
<eventNotificationMsg xmlns="http://www.xxx.yyy.com"; xmlns:xsi = "http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation = "http://www.xxx.yyy.com"; http://www.xxx.yyy.com/enm.xsd";>
... </eventNotificationMsg>
Best wishes, Dave

Hello,
Im using dom4j 1.4 and im trying to validate my xml against a schema. I tried using the SAXValidatorDemo.java (shipped along with dom4j) to test the validation. I get the following error from the errorhandler
<errors> <error column="23" line="2">Document root element
"eventNotificationMsg",
must match DOCTYPE root "null".</error> <error column="23" line="2">Document is invalid: no grammar
found.</error>
</errors>
Im using xml schemas, not dtds, so i didnot include the DOCTYPE for the
xml.
Any help is appreciated, Thank you.
My xml is as follows:
