Re: Problem with connection beetwen Tomcat and Apache via mod_jk?
Hi Chris, I'm setting up Tomcats on Unix (FreeBSD), I have no experience with Windows, so I can't help, but in theory it should require to change Tomcats ports (listener and others). Regards, Paweł Hi Pawel, I'm afraid I can't help you with your specific problem but have a question of my own. Are you setting up your multiple Tomcats on UNIX or Windows? If you're setting up on windows, could you tell me how you went about this? I've been struggling with it for a while now and I have no previous experience setting this kind of thing up. Thanks.
