I have a controller method as follow.
@RequestMapping("/edit/{jobId}")
public String editJob(@PathVariable("jobId") Integer jobId,Model model){
model.addAttribute("id",jobId);
return "edit";
}
in which i am passing the jobId to get the instance of the job by id and returning "edit" string so that it maps to edit.jsp as per the InternalResourceViewResolver. But when i click on the link it goes to /edit/44 in which case 44 would be the id of the job for which the edit link belongs to. Finally i got the error stating no resource found.

1) First create data at the server side and pass it to a JSP. Here a list of student objects in a servlet will be created and pass it to a JSP using setAttribute(). 2) Next, the JSP will retrieve the sent data using getAttribute(). 3) Finally, the JSP will display the data retrieved, in a tabular form.
In editJob method your are returning only id of job with model attribute to edit.jsp. But actually on edit.jsp page you need job object so you need to get job object by id add it as model attribute.
@RequestMapping("/edit/{jobId}")
public String editJob(@PathVariable("jobId") Integer jobId,Model model){
//model.addAttribute("id",jobId); this is wrong
Job job = jobService.getJobById(jobId);
//write method in jobservice to get job by id i.e. getJobById(Integer jobId);
model.addAttribute("job",job)
return "edit";
