xml schema validation (JAXP 1.3 JDK 1.4.2)

[tremalnaik]

Hello,
I'm trying to validate the xml string which root follows:

<ScenarioResponse
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:noNamespaceSchemaLocation="ScenarioResponse.xsd">
...............
</ScenarioResponse>

with the schema file ScenarioResponse.xsd:

<xs:schema
xmlns:xs="http://www.w3.org/2001/XMLSchema"elementFormDefault="qualified">
........
</xs:schema>

My code:

private void validate(String schemaPath, String xml) throws
SAXException,
ParserConfigurationException, IOException
{
// parse document
DocumentBuilderFactory dbf =
DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.parse(new InputSource(new
StringReader(xml)));
// create schema
SchemaFactory sf =
SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
sf.setErrorHandler(new myErrorHandler());
InputStream iStream =
Thread.currentThread().getContextClassLoader().getResourceAsStream(schemaPath);
StreamSource ss = new StreamSource(iStream);
Schema schema = sf.newSchema(ss);
// validate
Validator validator = schema.newValidator();
validator.setErrorHandler(new myErrorHandler());
validator.validate(source);
}

executing the last instruction I get

org.xml.sax.SAXParseException: cvc-complex-type.3.2.2: Attribute
'xsi:noNamespaceSchemaLocation' is not allowed to appear in element
'ScenarioResponse'.

I try to use another instance of the SchemaFactory so I try the
following:

SchemaFactory sf =
SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_INSTANCE_NS_URI);

the result is:

2005-10-27 16:17:17,932 [http-0.0.0.0-8080-1] ERROR [ROM] [THREAD: 1]
java.lang.IllegalArgumentException:
http://www.w3.org/2001/XMLSchema-instance
at
javax.xml.validation.SchemaFactory.newInstance(SchemaFactory.java:181)

so I suppose an instance for this schema is not implemented.

Can someone give me a direction, please?

I'm trying to validate the xml string which root follows:

see http://mindprod.com/jgloss/xsd.html
for code to do that.

 

[tremalnaik]

see http://mindprod.com/jgloss/xsd.html
for code to do that.

thanks Roedy, but now I have the proof that my code is correct
(probabily).

First, I upgraded to sdk 1.5.0 and the problem was still there.

But the same snipplet of code, if run from a raw console, behaves
properly. When I use it from inside a web application (deployed into
jboss) I get the exception.

So I think I have a classpath problem, with old classes hiding the new
shipped with the latest JAXP/JDK

I have to figure out this.

Thanks

I have to figure out this.

Have a look it my little Where tool to find out where classes are
coming from.

See http://mindprod.com/jgloss/where.html

thanks, Roedy. I tried the JVM -verbose option also. It prints out to
console the location of loaded classes.

cheers,

Hello,

I try to validate a DOM Document using:

SchemaFactory factory=SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
Source schemaFile=new StreamSource("myschema.xsd");
schema schema=factory.newSchema(schemaFile);
Validator validator=schema.newValidator();
validator.validate(new DOMSource(document));


I don't validate using the parse(File) method, because I already have a DOM Tree in memory.

BUT now I receive the following error:

org.xml.sax.SAXParseException: cvc-elt.1: Cannot find the declaration of element 'catalogue'.
at org.apache.xerces.util.ErrorHandlerWrapper.createSAXParseException(Unknown Source)

at org.apache.xerces.jaxp.validation.DOMValidatorHelper.validate(Unknown Source)
at org.apache.xerces.jaxp.validation.XMLSchemaValidator.validate(Unknown Source)
at javax.xml.validation.Validator.validate(Unknown Source)

catalogue is my rootElement.

I'm using jdk 1.4.

Does somebody know how to solve this?

Thank you!

It is some bug and normally it it solved in jdk 1.5
see http://mail-archives.apache.org/mod.../<3262346.1146854608199.JavaMail.jira@brutus>

But I tried to use jdk 1.5 and I still receive this error!

Is there somebody who knows what to do?

Thanks in advance!
