Dear fellow Tomcat users, recently we migrated our application from Tomcat7 to Tomcat9. Most things work great so far, but we observed on issue. Basically serving static pages has stopped for us.
Our setup is Tomcat (7.0.62 or 9.0.12) behind Apache HTTPD (2.4.41 using mod_jk 1.2.46). Yes, 9.0.12 is not recent, but we are forced to that version. The mod_jk configuration basically looks like: <IfModule !mod_jk.c> LoadModule jk_module modules/mod_jk.so JkWorkersFile "conf/cb2/workers.properties" JkShmFile "logs/jk-runtime-status" JkLogFile "logs/mod_jk.log" JkLogLevel info JkWatchdogInterval 60 </IfModule> And then later inside a virtual host: # # CB2 - Portal # # Mount the "/cb2" application to worker "cb2" # JkMount /cb2/* cb2 # # Unmount "/cb2/docs" from worker "cb2" to allow static content # beeing served by apache. Same for "/cb2/cgi-bin" # JkUnMount /cb2/docs/* cb2 So we JkUnMount the "/cb2/docs" directory from the application base in order to server the content directly from Apache. "docs" itself is a symbolic link pointing outside the application base. With TC7, we observe the following in the apache access_log: [07/Oct/2019:12:30:47 +0200] [2 ms] 160.46.219.110 - "POST /cb2/docs HTTP/1.1" s:302 l:- S:TLSv1.2 C:ECDHE-RSA-AES256-GCM-SHA384 [07/Oct/2019:12:30:47 +0200] [20 ms] 160.46.219.110 - "GET /cb2/docs/ HTTP/1.1" s:200 l:6367 S:TLSv1.2 C:ECDHE-RSA-AES256-GCM-SHA384 So the POST from the application is redirected to the static content, which is served OK. With TC9 we see: [05/Oct/2019:02:58:13 +0200] [0 ms] #160.46.219.110# - "GET /docs HTTP/1.1" s:404 l:196 S:TLSv1.2 C:ECDHE-RSA-AES256-GCM-SHA384 As said, the major difference between the setups is TC7 vs. TC9. Any ideas for me to follow? I did not find anything in the migration 7->8 or 8->9 guides.
