Question

My html page sends only one parameter. I need to handle it and send a response. This code handles more than one parameter and in my case is not so good:

 Enumeration<?> paramNames = request.getParameterNames();
        while (paramNames.hasMoreElements()) {
            String paramName = (String) paramNames.nextElement();
        }

But how I can modify this code if I have only one parameter and do not know its name.
Thanks!

Try something like this.

Map<String,String[]> paramMap = request.getParameterMap();

    String  myValue = paramMap.get(paramMap.keySet().iterator().next())[0];
