--- Begin Message ---You are tryin to cast a string array to string. parameters are passed as key/value pairs of Strings to the web server, so the we assume that the generics mapping for parameters is <String, String>. In fact, compilers will allow you to use this generic: Map<String,String> parameters = request.getParameterMap(); for(String key: parameters.keySet()) { String value = parameters.get(key); // error happens here System.out.println(key + "=" + value); }Use somethin like Map<String,String[]> parameters = request.getParameterMap(); When you call request.getParameter("firstName");, it simply returns the equivalent of parameters.get(key)[0]; Hope this helps Animesh ________________________________ From: [EMAIL PROTECTED] on behalf of yitzle Sent: Tue 6/5/2007 1:37 AM To: Struts Users Mailing List Subject: [S2] Accessing URL encoded GET data (bug found?) I am implementing the ParamterAware interface to get to the parameter. The interface has a setParameters(Map parameters) that I'm supposed to be able to use to access the GET data encoded in the URL. >From the JavaDoc API: "Note that all parameter values for a given name will be returned, so the type of the objects in the map is java.lang.String[]." When I try reading data from the Map and converting to a String, I get a casting error: java.lang.ClassCastException: [Ljava.lang.String; cannot be cast to java.lang.String I did this: public void setParameters (Map map) { Object m = map.get("criteria"); message = m.toString(); } then displayed the message. I get "[Ljava.lang.String;@e35bb7" Any clues?
