Castor Exception : The prefix 'xml' is reserved

Discussion in 'Java' started by Christophe Geraud, Oct 14, 2003.

  1. I got the following exception with Castor: "The prefix 'xml' is reserved
    (XML 1.0 Specification) and cannot be declared."
    I got this exception using or not a mapping file.
    Can anyone tell what it means ?

    Here is the stack trace :

    java.lang.IllegalArgumentException: The prefix 'xml' is reserved (XML 1.0
    Specification) and cannot be declared.

    If I simplify it works, so somethings unsupported i think

    <?xml version="1.0"?>
    <xsd:schema version="1.0"
    xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <xsd:element name="PARAMETERS">
    <xsd:complexType>
    <xsd:sequence>
    <xsd:element name="General"/>
    <xsd:element name="Calibration"/>
    </xsd:sequence>
    </xsd:complexType>
    </xsd:element>
    </xsd:schema>
