[Abhineet Joon]

	try
           	{
           		System.out.println("1");
           		StreamSource[] sources = new StreamSource[5];
           		System.out.println("2");
           	 	File file1 = new File(System.getProperty("user.dir")+System.getProperty("file.separator")+
          				 "XMLSchema"+System.getProperty("file.separator")+XSDFileName);
           	    File file2 = new File(System.getProperty("user.dir")+System.getProperty("file.separator")+
             				 "XMLSchema"+System.getProperty("file.separator")+XSDFileName1);
                File file3 = new File(System.getProperty("user.dir")+System.getProperty("file.separator")+
             				 "XMLSchema"+System.getProperty("file.separator")+XSDFileName2);
                File file4 = new File(System.getProperty("user.dir")+System.getProperty("file.separator")+
             				 "XMLSchema"+System.getProperty("file.separator")+XSDFileName3);
                File file5 = new File(System.getProperty("user.dir")+System.getProperty("file.separator")+
             				 "XMLSchema"+System.getProperty("file.separator")+XSDFileName4);
                System.out.println("3");
           	 	
                sources[0] = new StreamSource(file1);
           	 	sources[1] = new StreamSource(file2);
           	 	sources[2] = new StreamSource(file3);
           	 	sources[3] = new StreamSource(file4);
           	 	sources[4] = new StreamSource(file5);
           	 	
           	 	System.out.println("4");
        	 	
           	 	SchemaFactory schemaFactory = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
           	 	System.out.println("5");
           	 	schema = schemaFactory.newSchema(sources);
           	 	System.out.println("6");
           	 	
           	 	System.out.println("B");
           		validator = schema.newValidator();
           		
           	}

I am geting the error src-resolve: Cannot resolve the name 'UserAuthResponse' to a(n) 'element declaration' component.
