java.lang.IllegalStateException: Unable to process parts as no multi-part configuration has been provided

I correctly written servlet url in .xml file 

CourseSchedule.java

@WebServlet("/CourseSchedule")

@MultipartConfig()
@@Named("CourseSchedule"
public class CourseSchedule extends HttpServlet
{
@ComponentImport
private TemplateRenderer tr;
@ComponentImport
private PageBuilderService pbs;
@ComponentImport
private ActiveObjects ao;

@Inject
public CourseSchedule(TemplateRenderer tr, PageBuilderService pbs,ActiveObjects ao)
{
this.tr=tr;
this.pbs=pbs;
this.ao=ao;
}

@Override

String url="jdbc:mysql://localhost:3306/LU_Data?useSSL=false";
String user="root";
String password="123456";

Random rand = new Random();
int n = rand.nextInt(9999) + 1;
String idTemp=(String.valueOf(n));

String semesterName=request.getParameter("semesterName");
Part part=request.getPart("scheduleFile");

PrintWriter pw=response.getWriter();
pw.print(semesterName);

InputStream is=null;

if(part != null)
{
long fileSize=part.getSize();
String fileContent=part.getContentType();
is=part.getInputStream();
}

try
{
Class.forName("com.mysql.cj.jdbc.Driver");

con=DriverManager.getConnection(url, user, password);

PreparedStatement pst=con.prepareStatement("INSERT INTO Course_schedule VALUES(?,?,?)");
pst.setString(1, semesterName);
pst.setString(2, idTemp);

pst.executeUpdate();

if(is!=null)
{
pst.setBinaryStream(3, is, (int) part.getSize());
}

int row=pst.executeUpdate();

if(row==0)
{
pw.print("Error in Uploading a file");
}
else
{
pw.print("File Uploaded Successfully");

}

}
catch(SQLException e)
{
e.printStackTrace();
} catch (ClassNotFoundException e)
