Hi Kiran
I've CC'd the list in case anyone else has a similar problem.
If a recent version of crimson.jar or xerces.jar is on the CLASSPATH then
dom4j will use that as the SAX parser via JAXP. If none of these are on the
CLASSPATH then a bundled version of Aelfred is used, which does not
validate.
So for DTD validation put crimson.jar or xerces.jar on the CLASSPATH. If you
wish to validate against an XML Schema then try xerces.jar.
An alternative is to use Sun's MSV library for validation, which allows you
to use DTD, XML Schema, Relax NG, Relax or TREX as the schema languages.
There's an example in the daily build at
dom4j/src/samples/validate/JARVDemo.java
If you are validating an existing dom4j document then we recommend you try
MSV as it avoids turning the document into text and then parsing it again -
MSV can work purely off of SAX events generated from the dom4j document.
(I'll also add the above to the FAQ)
