How can I get URL parameters which have no value?

access using URL:

http://127.0.0.1/test.jsp?action=test&abc

or

http://127.0.0.1/test.jsp?abc

how can I get the String "abc" ?

thanks for help :)

request.getQueryString();

returns the whole query string after the URL.

<% java.util.Enumeration names = request.getParameterNames();
    while(names.hasMoreElements()){
        out.println(names.nextElement() + "<br>");
    }
    %>

I don't think there is a simple way to do this. Basically you need to iterate over the request's query parameter names and look for the parameter or parameters that don't have a value. I suspect that you will need to resort to embedding a Java scriptlet, or writing your own Tag (in Java).

A better idea is to stick to "name=value" syntax in your URL query.
