HTTP Status 405

[Pranav Pal]

What causes the following error:
HTTP Status 405 - HTTP method POST is not supported by this URL

Thanks in advance

[Ulf Dittmer]

That message is actually very much to the point: you're using HTTP POST to access an URL that does not support POST. If the URL is mapped to a servlet, it most likely means that you have not provided an implementation of the doPost method. (The doPost method inherited from GenericServlet generates this error.)

Once we have overridden doPost() of GenericServlet,how does it gets called

[Ulf Dittmer]

It gets called as the result of submitting an HTML form that has an attribute method="POST".
