When is doPut() called in a servlet?

Question

Hi I was just curious when is the doPut() method in a servlet called. I know that if the form on a jsp/html page has a "post" method then the doPost() is called otherwise if it has a "GET" then the doGet() is called.When is the doPut() called ??

Solution 1

The doPut() method handles requests send by using the HTTP PUT method. The PUT method allows a client to store information on the server. For an example, you can use it to post an image file to the server. As the above answer says, goGet() and doPost() are in use, mostly. In my case, I use only these two, and I am getting only get requests, so I simply transfer the get request to doPost() and do my job easily.

Solution 2

When an HTTP PUT request is received, naturally.

Can a page do a PUT request by code?

The only valid method attribute values of a <form> are get and post, according to the HTML5 spec. I assume that's what you're asking.

Or put another way, if you don't know when you're expecting to receive a PUT request, that probably means you don't need to care about it.
