Hi,

I am trying to implement a logger in my seam 1.2 + Icefaces 1.5.3 app. I would like to log the browser type that is accessing the site.

Code:

 HttpServletRequest request = (HttpServletRequest)facesContext.getExternalContext().getRequest();
 
 String ip = request.getRemoteAddr();
 String browserType = ((HttpServletRequest)request).getHeader("user-agent");

This throws a nullpointer exception from com.icesoft.faces.env.ServletEnvironmentRequest..

Looking at the code from ServletEnvironmentRequest I noticed that the headers are initialized but then are set to null:
Code:

 
         [b]headers = new Hashtable();
         items = req.getHeaderNames();
         name = null;
         while (items.hasMoreElements()) {
             name = (String) items.nextElement();
             headers.put(name, req.getHeaders(name));
         }[/b]
 
         parameters = new Hashtable();
         items = req.getParameterNames();
         while (items.hasMoreElements()) {
             name = (String) items.nextElement();
             attributes.put(name, req.getParameterValues(name));
         }
 
         scheme = req.getScheme();
         serverName = req.getServerName();
         serverPort = req.getServerPort();
         locale = req.getLocale();
 
         locales = new Vector();
         items = req.getLocales();
         while (items.hasMoreElements()) {
             locales.add(items.nextElement());
         }
 
         isSecure = req.isSecure();
 
         //Copy servlet specific data
        [b] headers = null;[/b]

I tried removing the headers=null; part but then I get nullpointer exceptions from

Code:

 public String getHeader(String name) {
         Enumeration allProps = (Enumeration) headers.get(name);
         if (allProps.hasMoreElements()) {
             return (String) allProps.nextElement();
         }
         return null;
     }

Maybe I am doing something wrong, or is it a problem with the ServletEnvironmentRequest implementation?

thanks,
Dustin
