HTML Entities (for e.g. &int) are getting decoded as symbols in JSF Backing Bean

Question

I have a JSF hInputTextBox with takes URLs are input and saves it into a DB table on click of a submit button.

In the backing bean handler for submit button, I try to read the value in hInputTextBox using request.getParameter("httpUrl"). It works fine for almost all URLs except the one which has content resembling to HTML entities.

hInputText value= "http://ww.jk.com?t=t&interface=k"

BackingBean code:

  FacesContext context = FacesContext.getCurrentInstance();
        HttpServletRequest request = (HttpServletRequest) context
                .getExternalContext().getRequest();
   String httpUrl = request.getParameter("httUrl")

Value in httpUrl = http://ww.jk.com?t=t∫erface=k

If you see, the &interface=k part is changed to ∫erface=k , where &int (with a semi-colon ideally) is the HTML code for ∫ symbol.

How can I get the URL value as it is?
