    mod_jk1.2.6 & JBoss

    C G Newbie

      I have read numerous posts dealing with tomcat, apache and mod_jk and it seems that I am not the only one having issues. In requesting a servlet in form of http://myurl/mytest/ (where mytest is the servlet working fine when accessed as: http://myurl:8080/mytest/) I get a 500 Internal server error. Upon the suggestion the wiki on this site on mod_jk i added worker.list=node1 in workers.properties.

      Have been working ono just this for the past 2 days so I hope someone will have a suggestion on how I may fix this problem.
      NOTE: in the XML excerpts below i removed the starting < because otherwise it wouldn't have outputed to this site.


      My setup
      ----------------------------
      JBoss 3.2.7RC1
      Apache 2.0
      mod_jk1.2.6


      workers.properties
      ----------------------------
      # Define Node1
      worker.list=node1
      worker.node1.port=8009
      worker.node1.host=localhost
      worker.node1.type=ajp13
      worker.node1.lbfactor=1
      #worker.node1.local_worker=1 (1)
      worker.node1.cachesize=10

      # Load-balancing behaviour
      worker.loadbalancer.type=lb
      worker.loadbalancer.balanced_workers=node1
      worker.loadbalancer.sticky_session=0
      worker.loadbalancer.local_worker_only=1
      worker.list=loadbalancer


      mod-jk.conf
      ----------------------------
      # Load mod_jk module
      # Specify the filename of the mod_jk lib
      LoadModule jk_module modules/mod_jk.so
      # Where to find workers.properties
      JkWorkersFile conf/workers.properties
      # Where to put jk logs
      JkLogFile logs/mod_jk.log
      # Set the jk log level [debug/error/info]
      JkLogLevel info
      # Select the log format
      JkLogStampFormat "[%a %b %d %H:%M:%S %Y]"
      # JkOptions indicates to send SSK KEY SIZE
      JkOptions +ForwardKeySize +ForwardURICompat -ForwardDirectories
      # JkRequestLogFormat
      JkRequestLogFormat "%w %V %T"
      JkMount /* loadbalancer


      httpd.conf
      ----------------------------
      [..]
      Include conf/mod-jk.conf

      JkMount /*.jsp ajp13
      JkMount /mytest/* ajp13
      JkMount /mytest ajp13

      mod_jk log file (these lines get repeated quite a few times)
      ---------------------------------------------------------------------

      JBoss and Apache are started. I was even able to telnet to port 8009 and send data to jboss who protested with an error in packet or something similar.

      If anyone can give any suggestions I would very very much appreciate it.
      Thank you,

      Chris
