i fixed this error. thanks for your help and your page is very helpful for me . i am beginner of java sprint mvc frame work this my first java project. i realy thank's for you team

vishwas · Answer

@dilrukshirajapakshe,

I observe that the X-Value being passed in the view is a string, whereas X-Value can either be number or date-time. However you can use label to show names, which accepts string. Can you try changing map.put("x", xVal); to map.put("label", xVal); in Report.jsp (line no: 29) and check if it works?

If this doesn't solve your issue, I request you to export your project as war/archive along with database so that we can run the project locally, understand your issue better and help you out.
