    Problem with mod_jk 1.2

    pergesu Newbie

      I think this is a problem with Apache, but I'm not sure. I'm trying to set up an Apache front end with mod_jk, but whenever I try to start Apache, I get:

      undefined symbol: apr_filepath_name_get

      No clue what that is, and a Google search yields one worthless result.

      Any ideas?

          check that the mod_jk.so file is in your /modules folder

            It's in there...it seems that the problem is that this function being called by mod_jk isn't defined anywhere.

              hi pergesu

              did you compile mod_jk yourself ?
              or are you using a "binary" version ?

              cheers

                I used a binary version at first. Then I tried compiling my own, and Apache started up fine.

                Now I'm having a new problem. I get a 500 Internal Server Error whenever I try to access a resource that should be passed on to JBoss/Tomcat. I checked out the mod_jk log file, and this is what I see:

                [Thu Jan 13 13:00:56 2005] [jk_uri_worker_map.c (445)]: Into jk_uri_worker_map_t::map_uri_to_worker
                [Thu Jan 13 13:00:56 2005] [jk_uri_worker_map.c (459)]: Attempting to map URI '/status'
                [Thu Jan 13 13:00:56 2005] [jk_uri_worker_map.c (473)]: jk_uri_worker_map_t::map_uri_to_worker, Found an exact match ajp13 -> /status

                So it seems to map it fine...when I make a request for status, it knows it's supposed to go to the worker named ajp13. But then for some reason it can't find the worker.

                  I'm posting my config files to provide a bit more info. I want to point out that I changed the worker name to default now, following a guide I found, so that's different from the output I posted above. The output's the same though, just that now the worker name is default, rather than ajp13.

                  Here's my workers.properties file:

                  # Define worker
                  workers.list=default
                  worker.default.port=8009
                  worker.default.host=localhost
                  worker.default.type=ajp13
                  


                  And here's the section of httpd.conf where it's all set up
                  #
                  # mod_jk settings
                  #
                  JkWorkersFile "conf/workers.properties"
                  JkLogfile "logs/mod_jk.log"
                  
                  JkLogLevel debug
                  
                  JkMount /*.jsp default
                  JkMount /*.do default
                  JkMount /status default
                  
                  # End of mod_jk settings

                    I got it working. It was just a little typo...workers.list should have been worker.list.

                    Lot of work to set up the connection, but now it's running smoothly :)
