You need to retrieve the HttpServletRequest from your page context. In your tag library just use this to get it:

PageContext pageContext = (PageContext) getJspContext();  
HttpServletRequest request = (HttpServletRequest) pageContext.getRequest();

For e.g.: You have a html form in your JSP page:

<form action="/someServlet">
   <input type="text" value="yourValue" name="yourParameterName"/>
</form>

To get your parameter use:

String yourValue = request.getParameter("yourParameterName");
