Hi Michael, The problem seems to be this initial declaration in the xmldsig-core-schema.xsd:
<!DOCTYPE schema PUBLIC "-//W3C//DTD XMLSchema 200102//EN" "http://www.w3.org/2001/XMLSchema.dtd"; [ <!ATTLIST schema xmlns:ds CDATA #FIXED "http://www.w3.org/2000/09/xmldsig#";> <!ENTITY dsig 'http://www.w3.org/2000/09/xmldsig#'> <!ENTITY % p ''> <!ENTITY % s ''> ]> If I remove that section from the xsd file, then there's no problem using the catalog with the SchemaFactory. If the declaration is there I get the error message mentioned previously. XMLSchema.dtd is referenced in that declaration. I've tried to solve the problem by writing this in the xml catalog: <public publicId = "-//W3C//DTD XMLSchema 200102//EN" uri="/path/to/XMLSchema.dtd"/> , keeping a local copy of XMLSchema.dtd. I've also tried putting: <public publicId="http://www.w3.org/2000/09/xmldsig#"; uri="/path/to/xmldsig-core-schema.xsd"/> No luck with any of those. So status is that cutting out the DOCTYPE declaration from the xmldsig-core-schema makes it possible to validate all schemas locally with the catalog, otherwise not. Regarding your question if I tried opening an InputStream with java.net.URL I'm not sure what you want me to accomplish? In short, a schema I have makes use of elements from xmldsig-core-schema, and I would simply like to be able to do my schema validation with a local copy of this schema rather than having Xerces SchemaValidator be dependant on establishing a connection to: http://www.w3.org/TR/xmldsig-core/xmldsig-core-schema.xsd (I think I gave an incorrect address to this schema in my previous mail) Thanks, Simon On Dec 3, 2007 2:19 AM, Michael Glavassevich <[EMAIL PROTECTED]> wrote: > Hi Simon, > > "file:/path/to/xmldsig-core/xmldsig-core-schema.xsd" seems like the correct > result for the "rewriteSystem" you wrote.
