            System.out.println(" in CompProgramController");
            Errors errors = null;
            CompProgram compProg = (CompProgram)command;
            
            System.out.println("Comp Program:"+ compProg.getCompProgDesc());
            
            CompProgramValidator rcv = new CompProgramValidator();
            rcv.validate(compProg, errors);
            
      

            if(!errors.hasErrors())
            {
                  CompProgramServiceImpl compPrImp = new CompProgramServiceImpl();
                  try {
                        String compId = compPrImp.addCompProgram(compProg);
                  }
                  catch(Exception e)
                  {
                        //throw new Exception();

Hi,

Put a null check while using errors. Replace the line with '  if(!errors.hasErrors())' with '  if(null != errors && !errors.hasErrors())'.
