Well, your code is definitely running. It's trying to access the URL "http://d1uap:4901/UMI/servlet/HUControlServlet/"; using an HttpURLConnection object. It looks like your code isn't properly catching FileNotFoundException (which really is a stupid exception for URLConnection to throw IMHO) when the URL is not accessible. Or do I have this wrong, and the exception is occurring in a driver class you've written to access the server? Could you post your <Connector> configuration from server.xml? What happens when you telnet to d1uap:4901 ? > Here is the localhost_access_log entry from the test that generated the > stack trace (servlet running on Tomcat 6.0.18).

It looks like that's what your code is requesting (it's up there in the exception) but you have mapped this exact URI in your web.xml: > <servlet-mapping> > <servlet-name>HUControlServlet</servlet-name> > <url-pattern>/UMI/servlet/HUControlServlet</url-pattern> > </servlet-mapping> The trailing slash is likely to be the problem. What happens if you make the request without the trailing slash? Or, what happens if you change your URI mapping to: <servlet-mapping> <servlet-name>HUControlServlet</servlet-name> <url-pattern>/UMI/servlet/HUControlServlet*</url-pattern> </servlet-mapping> - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkqhJygACgkQ9CaO5/Lv0PD+owCghZFjel33q2anejx6BzvDpkE5 r+cAnA93bbfqqLk24fisYd01p/NxQuvg =ZxOF -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
