Hi All, Well after going back to Yahoo! I found a page that at least got Tomcat 4.1.29 talking to Apache 2 though mod_jk2 YES!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! :))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))) )))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))
http://www.kawao.com/java/docs/mod_jk.html (note the mod_jk2 is further down the page) Its not all in English but the critical parts are - look at the section titled httpd.conf file and the way they set-up the context mapping to /examples (It would be great if someone would translate as I couldn't find a link for an English version) Still getting the jk2_init() error but I can now move on. I will post a complete HOWTO in the next week Cheers, George ----- Original Message ----- From: "George Shafik" <[EMAIL PROTECTED]> To: "Nikola Milutinovic" <[EMAIL PROTECTED]>; "Peter O'Reilly" <[EMAIL PROTECTED]>; <[EMAIL PROTECTED]>; <[EMAIL PROTECTED]>; <[EMAIL PROTECTED]>; <[EMAIL PROTECTED]>; <[EMAIL PROTECTED]>; <[EMAIL PROTECTED]>; <[EMAIL PROTECTED]>; <[EMAIL PROTECTED]>; "Mark Eggers" <[EMAIL PROTECTED]>; <[EMAIL PROTECTED]> Cc: "Tomcat Users List" <[EMAIL PROTECTED]> Sent: Saturday, January 10, 2004 2:03 PM Subject: Re: jk2_init() Can't find child xxxx in none of the 1024 scoreboard slots > Hi Nikola and any one else that can help, > > I'm still stuck on jk2_init() error - > even though many developers out there reckon this is not an issue I still > find it concerning that Apache2 is trying to find a Child process and > reports it as an [error]. > > [Sat Jan 10 13:15:08 2004] [notice] mod_jk.post_config() first invocation > [Sat Jan 10 13:15:08 2004] [notice] mod_jk.post_config() second invocation > [Sat Jan 10 13:15:08 2004] [error] jk2_init() Can't find child 2089 in none > of the 256 scoreboard slots > [Sat Jan 10 13:15:08 2004] [error] jk2_init() Can't find child 2090 in none > of the 256 scoreboard slots > [Sat Jan 10 13:15:08 2004] [error] jk2_init() Can't find child 2091 in none > of the 256 scoreboard slots > [Sat Jan 10 13:15:08 2004] [error] jk2_init() Can't find child 2092 in none > of the 256 scoreboard slots > [Sat Jan 10 13:15:08 2004] [error] jk2_init() Can't find child 2093 in none > of the 256 scoreboard slots > [Sat Jan 10 13:15:08 2004] [notice] Apache/2.0.48 (Unix) mod_jk2/2.0.3-dev > configured -- resuming normal operations > [Sat Jan 10 13:15:24 2004] [error] [client 192.168.0.100] File does not > exist: /usr/local/apache2/htdocs/examples > [Sat Jan 10 13:15:24 2004] [error] jk2_init() Can't find child 2095 in none > of the 256 scoreboard slots > [Sat Jan 10 13:15:30 2004] [error] [client 192.168.0.100] File does not > exist: /usr/local/apache2/htdocs/examples > [Sat Jan 10 13:15:33 2004] [error] [client 192.168.0.100] File does not > exist: /usr/local/apache2/htdocs/examples > [Sat Jan 10 13:15:37 2004] [error] [client 192.168.0.100] File does not > exist: /usr/local/apache2/htdocs/examples > [Sat Jan 10 13:15:44 2004] [error] [client 192.168.0.100] File does not > exist: /usr/local/apache2/htdocs/examples, referer: > http://sslaptop.gsss.net/examples/ > [Sat Jan 10 13:15:48 2004] [error] [client 192.168.0.100] File does not > exist: /usr/local/apache2/htdocs/examples, referer: > http://sslaptop.gsss.net/examples/ > [Sat Jan 10 13:16:03 2004] [error] [client 192.168.0.100] File does not > exist: /usr/local/apache2/htdocs/jkstatus > [Sat Jan 10 13:15:08 2004] ( info ) [jk_logger_file.c (224)] Level WARN 0 > [Sat Jan 10 13:15:08 2004] ( info ) [jk_logger_file.c (224)] Level WARN 0 > [Sat Jan 10 13:15:08 2004] ( info ) [jk_logger_file.c (224)] Level WARN 0 > [Sat Jan 10 13:15:08 2004] ( info ) [jk_logger_file.c (224)] Level WARN 0 > [Sat Jan 10 13:15:08 2004] ( info ) [jk_logger_file.c (224)] Level WARN 0 > [Sat Jan 10 13:15:08 2004] ( info ) [jk_logger_file.c (224)] Level WARN 0 > [Sat Jan 10 13:22:47 2004] [notice] caught SIGTERM, shutting down > [Sat Jan 10 13:15:08 2004] ( info ) [jk_logger_file.c (224)] Level WARN 0 > > Anyway I've managed to rebuild all mod_jk2.so and all relative jar files > with no issues with the org.apache.coyote.tomcat4.CoyoteConnector. > Unfortunately I still can't talk to Tomcat directly from Apache via the > standard socket method. > > Following are: > snippet httpd.con > snippet server.xml > workers2.properties > jk2.properties > > Any help would be greatly appreciated as I've spent far too much time on > this with no real results is very frustrating. > Apologies for any previous stupid questions as I'm now unfortunately up to > speed with using mod_jk2, Apache2 and Tomcat 4.1.29 - just an aside this is > far too hard it should be made simpler as many of us out here don't want to > become C and Web Servlet Container Gurus.
