urlConnection 500

[Miran Cvenkel]

Does this stil exists ?
bug

making my own crawler and on certain pages like forinstance:
test


I allways get 500. No need to say the page itself works OK otherwise. On other pages there is no error.

      HttpURLConnection urlConnection = (HttpURLConnection)url.openConnection();
      urlConnection.setInstanceFollowRedirects(true);

      urlConnection.setAllowUserInteraction(false);

      InputStream urlStream = null;
      
      try
      {
          urlStream = urlConnection.getInputStream();
      }
      catch (IOException e)
      {
          ///exception 500

Have you looked up what the error code 500 means? It's an internal server error. So it has little to do with your program.

my mistake, found it, thanks

What 505 means, that even does not get to jsp, so I could caught something on breakpoint. Works normaly on access thrue browser.

this is from tomcat log:

the reason for 505 was, space not encoded in url param.
