how to servlet and jsp to contact us page same as 'java programming forums' contact us page. Contact us page means like feed back form. So please give me some suggestion to write code for servlet and jsp for feeback form must be submit to bv123@gamil.com
thanks in advance.

make a JSP page first.

In that JSP page put a form tag. In the form tag you have an attribute called "action". in that attribute but the location of you servlet. If you using Google App engine then you can use the web.xml to map the servlet with a name. Or if you not using App engine then simply put the location of your servlet .java file ex.
<form action="/jet/contact-us.java">
</form>

and then in the servlet get all the values from the fields in the form and then use sendresponse() function.
