How do I properly parse a query string that I receive from the browser? I am having trrouble...
As you can see from the parseQueryString source (below), the value of each hashtable entry is an array of one or more strings. If you do this: 
Hashtable params = HttpUtils.parseQueryString(req.getQueryString()); 
String name = ((String[]) (params.get("name")))[0];

you should attain your heart's desire. The javadoc for this function is wrong, in that it implies that arrays will only be used if a parameter is repeated. In my opinion, it's better to always return String[]s and have then be length 1 in some cases, rather than make people check every time whether they got an array or a single object. The string "[Ljava.lang.String;@1dce128" means "an array of Strings", which should provide a hint as to what is going wrong.

Next: (Answer) I have a directory within my servlets directory and things break when I try to use http://www.server.com/servlets/test/TestServlet, but when I put TestServlet directly in the servlets directory and remove the "test" from the URL, things work just fine. Is this a bug?
