Hello, I am using Tomcat 6.0.20 on Ubuntu 10.04 and have written a simple TomcatWeatherServlet as presented in http://www.ibm.com/developerworks/web/library/wa-cometjava/ I modified the servlet to stream weather feed to multiple curl clients. I am using curl 7.21.6 as my client.
When I run curl -i -k -v -trace https://<IP_Addr>:8443/Weather<https://%3cIP_Addr%3e:8443/Weather> from the command-line I get the following response for the first few times: <code> $ curl -i -k -v -trace https://<IP_Addr>:8443/Weather * About to connect() to <IP_Addr> port 8443 (#0) * Trying <IP_Addr>... connected * Connected to <IP_Addr> (<IP_Addr>) port 8443 (#0) * successfully set certificate verify locations: * CAfile: none CApath: /etc/ssl/certs * SSLv3, TLS handshake, Client hello (1): * SSLv3, TLS handshake, Server hello (2): * SSLv3, TLS handshake, CERT (11): * SSLv3, TLS handshake, Server key exchange (12): * SSLv3, TLS handshake, Server finished (14): * SSLv3, TLS handshake, Client key exchange (16): * SSLv3, TLS change cipher, Client hello (1): * SSLv3, TLS handshake, Finished (20): * SSLv3, TLS change cipher, Client hello (1): * SSLv3, TLS handshake, Finished (20): * SSL connection using DHE-RSA-AES256-SHA * Server certificate: * subject: XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX * start date: 2009-02-23 23:07:18 GMT * expire date: 2019-02-21 23:07:18 GMT * common name: XXXXXXXXXX (does not match '<IP_Addr>') * issuer: XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX * SSL certificate verify result: self signed certificate (18), continuing anyway. > GET /Weather HTTP/1.1 > User-Agent: curl/7.21.6 (x86_64-pc-linux-gnu) libcurl/7.19.7 OpenSSL/0.9.8k > zlib/1.2.3.3 libidn/1.15 > Host: <IP_Addr>:8443 > Accept: */* > < HTTP/1.1 200 OK HTTP/1.1 200 OK < Server: Apache-Coyote/1.1 Server: Apache-Coyote/1.1 < Content-Length: 0 Content-Length: 0 < Date: Wed, 29 Jun 2011 23:40:17 GMT Date: Wed, 29 Jun 2011 23:40:17 GMT < * Connection #0 to host <IP_Addr> left intact * Closing connection #0 * SSLv3, TLS alert, Client hello (1): </code> Observe that Content-Length is 0 in the response. Also when I do get the expected response which is, <code> > GET /Weather HTTP/1.1 > User-Agent: curl/7.21.6 (x86_64-pc-linux-gnu) libcurl/7.19.7 OpenSSL/0.9.8k > zlib/1.2.3.3 libidn/1.15 > Host: <IP_Addr>:8443 > Accept: */* > < HTTP/1.1 200 OK HTTP/1.1 200 OK < Server: Apache-Coyote/1.1 Server: Apache-Coyote/1.1 < Transfer-Encoding: chunked Transfer-Encoding: chunked < Date: Wed, 29 Jun 2011 23:46:18 GMT Date: Wed, 29 Jun 2011 23:46:18 GMT < <h2>Conditions for San Jose, CA at 3:52 pm PDT</h2> <img src="http://l.yimg.com/a/i/us/we/52/30.gif"/><br /> <b>Current Conditions:</b><br /> Partly Cloudy, 68 F<BR /> <BR /><b>Forecast:</b><BR /> Wed - Mostly Clear.

On Server logs I get for the error are: 16:40:16.916 INFO http-8443-exec-3 TomcatWeatherServlet:41 - Begin for session: BDD6B1808161F1DA99D5D3207F1A719B 16:40:16.959 INFO http-8443-exec-4 TomcatWeatherServlet:48 - End for session: BDD6B1808161F1DA99D5D3207F1A719B 16:40:17.033 INFO http-8443-exec-4 TomcatWeatherServlet:48 - End for session: BDD6B1808161F1DA99D5D3207F1A719B This was working when I was on HTTP. I have tried to debug this for a lot of time w/o success. Also I get two END events instead of one as seen in the Logs. Any insights will be helpful. Thanks, Sudeep
