METHODS, SYSTEMS AND COMPUTER PROGRAM PRODCUTS FOR VALIDATION OF XML INSTANCE DOCUMENTS USING JAVA CLASSLOADERS

An Extensible Markup Language (XML) schema file can be resolved by receiving an XML instance document that includes data to be validated using an XML schema file at an XML validating system. The XML instance document can be parsed to map an external XML schema reference to the XML schema file defined by a source outside the XML validating system to an internal XML schema reference defined internal to the XML validating system. The internal XML schema reference can be resolved using a Java Classloader to provide the XML schema file as an input stream to the XML validating system. Related systems and computer program products are also disclosed.
