Thanks a lot Vijaya. i managed to compile and run successfully the java code you sent. works perfect. my next question is: schema file for the xml is not defined in the xml file so i added the property '...external-noName...' in which i can define the external schema file to validate. works perfect. now, is it possible to cache this schema file, so that i dont have to read it all the time i need to validate xml?? is so then how? thanks a million once again. tom
