Hi,
I have an xml for which I have written the XSD. The validation code is my
servlet. My XML is not able to locate my XSD. They both are in the same
directory.
The servlet contains the method name validateCurrenciesXML which contains
the validation code.
The app server is weblogic. My classpath contains xerces.jar. JDK version is
j2sdk1.4.2_13
Please find attached all the requried files.
Please help
Thanks & Regards,
Amisha
