No, i am not using apache - its a standalone version of tomcat. To be honest, I find it rather awkward to be worried about the mod_jk versions, or whether i have a paricular module installed or using a particular connector, etc. With a tool being into such a wide use, I'm sure there are people who have done this before, but somehow, either I am missing something significant, or maybe others went through the same ordeal and have been unable to reproduce what they did, or maybe its just dumb hard luck!

I don't know if you are using apache but if you are using apache with tomcat DON'T USE the WebApp connector, is not maintained anymore and does not work correctly with apache 1.*, 2.*. USE mod_jk2 it works fine with the pool connection. I had the same problem a few days ago and I resolve the problem changing connectors. I hope this help.
