pom.xml is not valid because cvc-elt.1: Cannot find the declaration of element 'project'.

Hi,

I am getting this error when validating an xml file with an xsd.

pom.xml is not valid because cvc-elt.1: Cannot find the declaration of element 'project'.

The xml file actually contains the 'project' tag. I am wondering still why this error happens!!!.

Actually I am programmatically validates a supplied xml with the schema.
ie

try {
			File schemaLocation = new File(xsdFileName);
			Schema schema = factory.newSchema(schemaLocation);

			// 3. Get a validator from the schema.
			Validator validator = schema.newValidator();

			// 4. Parse the document you want to check.
			// Source source = new
			// StreamSource("D:/Setups/trang-20030619/trang-20030619/dev.xml");
			Source source = new StreamSource(xmlFileName);

			// 5. Check the document
			validator.validate(source);
			System.out.println(xmlFileName + " is valid.");
		} catch (SAXException ex) {
			System.out.println(xmlFileName + " is not valid because ");
			System.out.println(ex.getMessage());
		} catch (Exception e) {
			e.printStackTrace();
		}

This xml itself contains reference to a schema 'maven-v4_0_0.xsd'.

See the start tag of the xml
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

Is it like that if my xml file contains reference to another schema, the programmatic comparison with the supplied schema will not take place?
Please note that I should not delete the schema which is refernced in the xml file.

Please give me a solution for this..

thank you
Ajith

Not so. The supplied schema will always prevail. If it isn't "supplied" in the program, it will try to load what is specified. The operation might be successful following with the validation to proceed as usual, or fail leading to a File to read schema document SAXParseException...
