Hi,
I am trying to do multiple schema validation in Java. I don't understand where I am doing wrong. Any help will be appreciated.
abc.xsd
<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:xn="project-xml-r4j_another.xsd">
<xsd:import namespace="project-xml-r4j_another.xsd"/>
<xsd:element name="abc" type="abc">
</xsd:element>
<xsd:complexType name="abc">
<xsd:sequence>
<xsd:element name="test" type="test" minOccurs="0" maxOccurs="1">
</xsd:element>
<!--<xsd:element name="proj" type="xn:proj"/>-->
</xsd:sequence>
<xsd:attribute name="id" type="xsd:ID" use="required"/>
</xsd:complexType>
<xsd:complexType name="test">
<xsd:attribute name="id" type="xsd:ID" use="required"></xsd:attribute>
<xsd:attribute name="value" use="required">
<xsd:simpleType>
<xsd:restriction base="xsd:string">
<xsd:maxLength value="100" />
</xsd:restriction>
</xsd:simpleType>
</xsd:attribute>
</xsd:complexType>
</xsd:schema>
project-xml-r4j_another.xsd
<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" targetNamespace="project-xml-r4j_another.xsd" xmlns="project-xml-r4j_another.xsd" elementFormDefault="qualified" attributeFormDefault="unqualified">
<xsd:element name="proj" type="proj">
<xsd:annotation>
<xsd:documentation>
The project is the root tag of a project-xml.
</xsd:documentation>
</xsd:annotation>
</xsd:element>
<xsd:complexType name="proj">
<xsd:attribute name="id" type="xsd:ID" use="required"/>

schemaValidator.setErrorHandler(new MessageHandler());
// validate xml instance against the grammar.
schemaValidator.validate(new StreamSource("C:\\jaydeep\\Ericsson\\R5B\\project_tmmk17cells_xnaveen_project-xml.xml"));
} catch (SAXException e) {
throw new InvalidProjectXmlException("Project-xml validation failed, Exception: " + e.getMessage(), e);
} catch (IOException e) {

}
class MessageHandler extends DefaultHandler {

@Override

@Override

}
}
}
