XML : validation XML against XSD java

I've a problem. When I validate my xml online all is good. But when in eclpse it doesn't work. It's return an error: SAX Exception: schema_reference.4: Failed to read schema document 'file:/C:/Users/ASUS/Downloads/Task3_XML/Task3_XML/weapon.xml', because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not . This is my code

  public static void main(String[] args) {       boolean isValid = validateXMLSchema("weapon.xml","weaponXSD.xml");       if(isValid){          System.out.println(args[1] + " is valid against " + args[0]);       }else {          System.out.println(args[1] + " is not valid against " + args[0]);       }    }      public static boolean validateXMLSchema(String xsdPath, String xmlPath){    try {       SchemaFactory factory =           SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);       Schema schema = factory.newSchema(new File(xsdPath));          Validator validator = schema.newValidator();          validator.validate(new StreamSource(new File(xmlPath)));    } catch (IOException e){           System.out.println("Exception: "+e.getMessage());       return false;    }catch(SAXException e1){       System.out.println("SAX Exception: "+e1.getMessage());       return false;    }    return true;    

} My XML:

  <?xml version="1.0" encoding="UTF-8"?>  <Gun>  <Weapon>  <Model>Пістолет «Форт-12»</Model>  <Handy>one-handed</Handy>  <Origin>Україна</Origin>  <TTH>     <carry>близька [0;500 m]</carry>     <effectiveRange>10 m</effectiveRange>     <availabilityClips>true</availabilityClips>     <availabilityOptics>false</availabilityOptics>  </TTH>  <Material>метал</Material>    

And my XSD in short form:

   `  <?xml version="1.0" encoding="UTF-8"?>      <xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified"      xmlns:xs="http://www.w3.org/2001/XMLSchema">  <xs:element name="Gun">      <xs:complexType>        <xs:sequence>          <xs:element name="Weapon" maxOccurs="unbounded" minOccurs="0">            <xs:complexType>              <xs:sequence>                <xs:element name="Model">`    

Please if you have any idea write me because i don't understan whe is a problem really Thanks, Vika.
