Werner and Saladin- Sorry to jump in at the end here, but there might be an easy way around this issue. If all you need is a custom configured parser you can instantiate your own parser and have Castor use it:
1) Instantiate/configure a SAX parser (specify the external-schema-location feature) 2) Instantiate/configure an Unmarshaller instance 3) Call createHandler() on the Unmarshaller object to get an UnmarshalHandler which implements ContentHandler and ErrorHandler 4) Set the parser's content handler to the UnmarshalHandler object 5) Set the parser's error handler to the UnmarshalHandler object 6) Parse the document 7) Call getObject on the UnmarshalHandler to retrieve the root object Feel free to ignore me if I've completely missed the mark, but I hope that helps.

Okay, I don't think that what you want to achieve is possible without a small code change to the Unmarshaller. I just had a look at the JAXP API, and it looks like I have to provide you with an option to specify the http://apache.org/xml/properties/schema/external-schemaLocation"; feature of the JAXP Parser instance used internally by Castor. If this is an option for you, please create a new Jira issue at http://jira.codehaus.org/browse/CASTOR and attach the relevant fragments of this email conversation.
