Parsing with SAX parser

[Ismail Jaffer]

I need to validate an XML document against its shcema. I have the following code. This code validates XML schema (check.xsd) and XML document (check.xml) individually but XML is not validated againtst XML schema (like sequence ,enumeration etc.) I am using xerces parser come with Java 1.5 Do I need to set some property for doing this. Please some one help me. Thanks for help.
