Danny,
Castor will, by default, validate the object model prior to the
marshalling process. If you're using the source generator then the
generated descriptors contain some validation attributes that Castor
will use during this validation process. If you're not using the source
generator you'd have to create your own validators or validation step.
Castor's object model validation is not as "complete" as validating the
XML itself with the parser, but it should provide you with the basic
property level validation, so in your situation the strings that are too
long should be validated by Castor's object model validation process.
If you open up the *Descriptor.java files you'll see the validation code
to give you an idea of what Castor will validate against.

AHA! Yeah I am trying to go from Java->XML and get the same level of
validation that you would get when you go form XML->JAVA.
We are already exploring adding in our own validation step. I was just
hoping to leverage anything that castor provided.
thanks

Danny-
Are you validating during xml->java or java->xml? The properties given
tell the xml parser to validate against a given schema, but during
java->xml, I don't believe the parser is utilized (there might be an
option that I don't know about). My first idea would be to generate the
xml from the java objects, and then run that xml through a validating
parser to determine if the xml conforms to the schema.
I should mention that I don't use the source generator much at all, so
there may be options in there to help with validation that I don't know
about.

OK - popped those attributes into my properties file - regenerated the

strings that are WAY too long and should fail validation and will if I

I've attached my castor properties file.
I am trying to validate an individual object in the castor graph -
that is a piece of the schema.
do I need to build out the entire object graph in order for it to
validate correctly?
Thanks again, you all are being very helpful!

SWEET! Thanks for pointing this out. I am going to give it a go
straight away and let you know if it works out for me!
Thanks again guys.

Yes, as recently added to the XML F.A.Q. (though not released yet):
<p>To enable XML validation at the parser level, please add properties
to your
<tt>castor.properties</tt> file as follows:</p>
<code>
org.exolab.castor.parser.namespaces=true
org.exolab.castor.sax.features=http://xml.org/sax/features/validation,\
http://apache.org/xml/features/validation/schema,\
http://apache.org/xml/features/validation/schema-full-checking
</code>
<p>Please note that the example given relies on the use of Apache
Xerces, hence the
<tt>apache.org</tt> properties; similar options should exist for other
parsers.</p>
I hope this helps
