Spring: Request method 'POST' not supported

Question

Browsed the forum but didn't find solution which can solve my problem. There are 2 pages: index.jsp - start page which includes form to be populated and the list of results; edit.jsp - allows to edit data of any row from the list of results provided by index.jsp. When I fill in the form all the data subbmitted successfully, when I try to edit any row in the list of results I redirected to edit.jsp but if I submit the changes an exception is thrown: HTTP Status 405 - Request method 'POST' not supported. I would appreciate any idea how to treat the issue.

index.jsp

Answer 1

Your problem is that you are using relative mappings in your form, when you click on edit, your URL becomes /edit/{someid} and your edit.jsp form is loaded. When you edit the data and click submit, your URL will become /edit/{someid}/edited , the mapping will match the /edit/{someid} handler method witch is using a GET method and that is why you get your error.

To solve it, in your edit.jsp simple add a backslash to action, action="/edited"

Hope it helps
