One possibality of getting this error message because u may be using the old version of Xerces, so download the latest version of Xerces and keep the new xerces.jar in ur classpath.
i think this will solve ur problem Regards Vijay -----Original Message----- From: tom john [mailto:[EMAIL PROTECTED] Sent: Thursday, April 04, 2002 4:06 PM To: [EMAIL PROTECTED] Subject: xml validation with schema ERROR Hi, I am new validating xml with schema.
