I am having trouble getting the page to work. I have my form method to post and my servlet implements doPost(). However, it keeps showing me that I am not supporting the POST method.
I am just trying to do a simple website and insert values into my MySQL DB.
*type Status report message HTTP method POST is not supported by this URL description The specified HTTP method is not allowed for the requested resource (HTTP method POST is not supported by this URL).* the static page:

Solution: Use only the form button you mapped to your servlet action. Show activity on this post. If you're still facing the issue even after replacing doGet() with doPost() and changing the form method="post" . Try clearing the cache of the browser or hit the URL in another browser or incognito/private mode.
The Request Method' POST' Not Supported error is caused by a mismatch of the web browser configuration and the browser's URL format. In this case, the browser sends a URL request, the web server receives and recognizes the URL but cannot execute commands or grant access to the requested page.
It's because you're calling doGet() without actually implementing doGet(). It's the default implementation of doGet() that throws the error saying the method is not supported.

if you are using tomcat you may try this
<servlet-mapping> <http-method>POST</http-method> </servlet-mapping> in addition to <servlet-name> and <url-mapping>
