Trying to access a servlet on button click

Hello,

I am trying to call a servlet on button click.Its not a submit button,but a graphical button (not a part of form).
When i click the button get the message:

HTTP STATUS 405:HTTP method GET is not supported by this URL.
The specified HTTP method is not allowed for the requested resource.

When i reference a jsp page it displays the page.Is there any way that I can call a SERVLET and send some information along the servlet name.If yes ,what should be the code?

Thanks.

As this is about servlets, it has been moved to the Servlets forum.

I am afraid you cannot do that with servlets. Servlets only process the requests through the service() or doGet() or doPost() methods. You have to use a form with one of these methods to access the service methods. Clicking a graphical button without a from cannot take you to a servlet. There is no other way. Lets say if even if you send parameters in the URL, how will you invoke the service methods? You got to re-adjust your application.

What method did you override....

doget or dopost??

Horse pockey! There are numerous ways this could be accomplished via Javascript.

Servlet is overriding dopost method.

Servlet is overriding dopost method.

implement doget method.. and pass all the data you want to use in servlet in querystring.. for e.g.
http://url/servlet/MainServlet?userId=Ali&password=Ali

in doget method of servlet...get values of parameter via request.getParameter("userId")

Most probably you did not implement the doGet() method.
Try doing that first and tell us how it goes.

The problem is pretty much solved as i had not override the doGet method in the servlet.
One more question,how can i associate a dyanamic value with a url,as usually we append fixed value with url as below,

http://url/servlet/myservlet?companyid=xyz
but what if company id changes everytime?
