I just finished up configuring a fairly default configuration of Tomcat. My Apache configuration was pre-existing and post-tomcat it still has no issues. I am using mod_jk to (if I am saying this correctly) interface between Apache and Tomcat and have my conf files setup for my workers, etc.
I put my test file (Simply: http://tomcat.apache.org/tomcat-4.1-doc/appdev/sample/web/hello.jsp) into my
tomcat/webapps/ directory and then call it via http://localhost/jsptest/hello.jsp. From here Apache returns a
502 Bad Gateway response.
I confirmed this via the Apache logs, but beyond that I have no idea how to diagnose the issue. I assume the 502 is because Tomcat did not respond. I'd like to confirm if Tomcat received the request, but cannot locate the log file.
At this point I had thought my installation was complete, so not sure where to go from here. Any input would be appreciated.
localhost.log, etc do not have any data logged for the time that I made my requests.
Edit: Slowly figuring the configuration out. The following three lines appear in mod_jk.log when I make a request:
[Tue Jun 01 17:34:26 2010] [4207:3086195296] [error] ajp_connection_tcp_get_message::jk_ajp_common.c (1252): wrong message format 0x3c21 from 127.0.0.1:8080 [Tue Jun 01 17:34:26 2010] [4207:3086195296] [error] ajp_get_reply::jk_ajp_common.c (2055): (worker) Tomcat is down or refused connection. No response has been sent to the client (yet) [Tue Jun 01 17:34:26 2010] [4207:3086195296] [error] ajp_service::jk_ajp_common.c (2559): (worker) connecting to tomcat failed.
Edit: Changed the port in
mod_jk.log shows the following:
[Tue Jun 01 17:54:55 2010] worker localhost 0.003423
So Tomcat is getting the request, however a 404 (from Tomcat) is returned even though I added
hello.jsp to both my
apache/html/jsptest/ directories in order to cover all bases. Perhaps I am misunderstanding the Aliasing method? Not sure how it cannot find a file that exists in the two most logical places...
Edit: Well, I just walked myself straight through the problem. My port was wrong in workers.properties. Once I fixed that and saw the 404 from Tomcat I realized the configuration was working and the file couldn't be found. What I didn't realize was that the
jsptest directory needed to be in
tomcat/webapps/jsptest/. Now everything works... thanks for humoring me. Hopefully this helps someone.
