Hi
I working whit Web service in java, axis and Xerces2, this web
service get like paremeter an XML, the which use a schema whith
restriction, but the validations no work, when i introduce a bad
parameter.
Note: The error of validation are write by catalina.out
the xsd and xml was generate whith xmlspy
<?xml version="1.0" encoding="UTF-8"?>
<data xmlns:xsi=" <http://www.w3.org/2001/XMLSchema-instance>
