JSP to Servlet parameter passing

I have a scenario in which there is a jsp, which has couple of hyperlinks. One of the link is coded this way.

<a href="Example?op=srk>hyperlink 1</a>
<!--The value srk is replaced dynamically in code-->

The above link, would send the request to the servlet named Example passing the request parameter through the url. As it's a hyperlink, the request is sent to the Example Servlet's doGet() method. In that I am utilizing the request param, processing something and forwarding the request to another jsp further, attaching an attribute(with some object in it) for that request. Functionality works, and I got what I need. But, the side effect or the problem I feel is the URL in the browser has the request parameters visible as shown below. 

http://localhost:8080/context/Example?op=srk

I don't wish to see the parms which are being sent. Firstly, Is my approach reasonable? I mean, Is there any better alternative way to achieve this. I am using the core J2EE(JSP and Servlets), no frameworks, no JavaScript as of now.

I elaborating @Sezin's answer , the best way is to go with the POST method to avoid your parameters visible in the url.

As you said your are populating the dynamic value in the op=srk variable . you can use a html form to store the variable op in the form as hidden variable .

you can use the submit button in the form , so that you could handle the request in the doPost() of your servlet .

Hope this helps !!

As you click on this link, you're doing an HTTP GET request to your servlet which's why you see the parameters you're passing. You can consider yo use a form or an alternative so you can do an HTTP POST request. After that implementation, this will not be on the address bar.
