urlconnection

URL url = new URL("ftp://user:pass@ftp.example.com/thefolder/"); URLConnection connection = url.openConnection(); ... // List files in folder... Using something like the above, I was wondering how I could grab a list of files within folder 'thefolder'? Hi guys, Following on from this original question, I have put together this simple FTP connection which is all working and looking good. It can see all files in the /live/conf/ location and copies them all to the local /conf/ location. The only issue is, it's copying the files but there's no content.They are all 0KB and empty! Can anyone see

My code is like the following: URLConnection cnx = address.openConnection(); cnx.setAllowUserInteraction(false); cnx.setDoOutput(true); cnx.addRequestProperty("User-Agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)"); InputStream is = cnx.getInputStream(); Is it ok if I set the headers before I get the InputStream ? Will my header be sent, or will the server see the default URLConnection 's user-agent ( if any ) ? Ken Gentle The headers must be set prior to getting the InputStream to have any affect - an IllegalStateException will be thrown if the connection is already open. As far

I have a problem to understand the meaning of the connect() method in the URLConnection class. In the following code, if I use the connect() method, I get the same result if I don't use it. Why (or when) do I need to use it? URL u = new URL("http://example.com"); HttpURLConnection conn = (HttpURLConnection) u.openConnection(); conn.connect();//with or without it I have the same result InputStream in = conn.getInputStream(); int b; while ((b = in.read()) != -1) { System.out.write(b); } Amanda HttpURLConnection conn = (HttpURLConnection) u.openConnection(); only creates an Object connect()

I'm making a simple URL request with code like this: URL url = new URL(webpage); URLConnection urlConnection = url.openConnection(); InputStream is = urlConnection.getInputStream(); But on that last line, I'm getting the "redirected too many times error". If my "webpage" var is, say, google.com then it works fine, but when I try to use my servlet's URL then it fails. It seems I can adjust the number of times it follows the redirects (default is 20) with this: System.setProperty("http.maxRedirects", "100"); But when I crank it up to, say, 100 it definitely takes longer to throw the error so I

Here is my code: String addr = "http://172.26.41.18:8080/domain/list"; URL url = new URL(addr); HttpURLConnection httpCon = (HttpURLConnection) url.openConnection(); httpCon.setDoOutput(true); httpCon.setDoInput(true); httpCon.setUseCaches(false); httpCon.setAllowUserInteraction(false); httpCon.setRequestMethod("GET"); httpCon.addRequestProperty("Authorization", "Basic YWRtaW4fYFgjkl5463"); httpCon.connect(); OutputStreamWriter out = new OutputStreamWriter(httpCon.getOutputStream()); System.out.println(httpCon.getResponseCode()); System.out.println(httpCon.getResponseMessage()); out.close();
