Thanks for a quick reply. What does our custom connector do?
Well, we have a server program which is listening on a port which is mandatory to be open/accessible for the outside world. Outside world only talks to this component which in turn hands off (dup system call) the socket to the other processes. Tomcat being one such process. Our custom connector accepts the handed-off socket and then resumes the normal processing done by Tomcat. Now for NIO connector, seems we need to have a custom implementation of the SocketChannel but not sure how it might work.

BIO is problematic because of many requirements for non-blocking behavior. It's easy to emulate blocking behavior (e.g. ServletRequest.getInputStream) based upon non-blocking building blocks (e.g. NIO connector) but next to impossible to emulate non-blocking behavior (websocket, comet, etc.) using blocking building blocks (BIO connector). Unfortunately, the reality is that a blocking I/O connector is no longer feasible for Tomcat. So... what does your custom connector do? Perhaps there's a better way to achieve your goal, or perhaps Tomcat's connectors could be re-factored to make it easier to customize something specific for you without having to re-write the whole connector. - -chris -----BEGIN PGP SIGNATURE----- Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQIcBAEBCAAGBQJYolY6AAoJEBzwKT+lPKRYpCEQALefIMml43cS3r254mGE/pFS +QWDnaPG2t96oXM8GExUWm6jGBCGarxt7FBxxku112DS8+5NzkmEmP8BdkAkOIeN 7p/1jiGhZ4Koz7ER4JUzAXbbSFmJBjOXWfxYPzecZHrBBdfndoBx2PWRe/Ew4LNY ujJLSwZWuUSlZu1CBzPT/UU0klthqRRsfHH8JrHe64Jm+qZuPIITjr0G15IYSEU3 SihVCFMmA//yQfRb8rNN9UCM8lYYtu4oYwiythPNt30wz0e5XzOemyX+f/MMlFyD yWrKlOI9x+g9OVoMNSYvsq+9EO/TTzTW6mWtW26rnHskEz0i/98QIVqg9XIRIvrM 3mPq6Ufuq6Aq75WIVtJcKUe4voDu9KSmOHb7AKsLPFrB6WbzDluSSWD3VpxM/q5R gluvGG9CcCIRl1ie1ljg3qO90ZPno38RuQl+vxKSsGlY5t/mSce1M4ffBgJdg/T7 GpKZ/+GYTUuDg/jE+9pav/yO2mx8Hj/Oo6TvGCACT4o+sRXtceORcq93c8npCT0L 4+jvS2aJT0Gud3jn2gZ9qZnXGdFWdq59LTnZ1/s6p9gGHglCtWBx9j3fMkS53y1y 41giiY9GXKuEzyHUlSaTT3rLucJCzcJWvHi/k1muqclUn5/Ht2NVHXoLmxVPxgzL K0bIRYJ9K2R/ou+6YPiV =zu1M -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
