My own experience is that if apache comes up before tomcat, you will have an 80% or greater chance of failure and need to do a manual restart of both tomcat and apache.
On the flip side, if you have apache and tomcat up and running nicely and do a tomcat restart, I need to restart apache 10% to 15% of the time. An apache restart without a tomcat restart appears to result in a 5% or less failure rate. -----Original Message----- From: Denise Mangano [mailto:[EMAIL PROTECTED]] Sent: Monday, December 23, 2002 10:50 AM To: 'Tomcat Users List' Subject: RE: [OT] Mod_jk - won't execute jsp or servlets That is definitely a possibility. On average I waited about 10 seconds or so. I usually do ps -ef to make sure tomcat is running, but don't try to pull it up in the browser to see if it really is running. I will keep this checklist for the future. Curious though. Apache is in my startup - Tomcat is not (YET). Will this cause problems if I boot up then start Tomcat? Is it better to remove httpd from startup so I can be sure to start tomcat first? Thanks.

You got me curious as well, and I did change it back to "0" (mind you I was very scared to) . Oddly enough, everything still works. I even tried executing some of the examples that I hadn't accessed yet to make sure it wasn't working from classes that were built previously, and it still works like a charm. If it wasn't the connection timeout setting then I haven't a clue what would have made it start working....

My installation with tomcat 4.1.18 does work with the default connectionTimeout="0". I would be interested to know if you change it back to 0, if it will still works.

But YAY!!!!! :-P Milt - it looks like the timeout was what was doing it. Weird thing is - I didn't edit that. Unless I did something by mistake that is the way that it was shipped!! Everything is working great!! I can access all static pages as well as execute all servlets and JSP. I better knock on wood and pray nothing goes wrong to make it stop working ;) Thank you SO MUCH to everyone for all of your help!! I definitely would have been pulling my hair out from the roots if it weren't for this list!! Jerry - where do you stand with your set up? Since we have the same set up would you like me to send you my files now that it is working for me??

Where Apache is > expecting it to listen on I am not sure. Actually, you've got it backwards. workers.properties is part of the Apache config, and indicates where Apache is expecting to find the (Tomcat side of the) Ajp connector. server.xml is part of the Tomcat config, and tells Tomcat where it should listen for Ajp (and other protocols). > The email I sent was correct > - the uncommented ports are those that were listed.

I responded to that email -- and in fact the connection timeout was the only thing that looked odd to me. So that might be what's causing the problem. > -----Original Message----- > From: Milt Epstein [mailto:[EMAIL PROTECTED]] > Sent: Monday, December 23, 2002 11:27 AM > To: Tomcat Users List > Subject: Re: Mod_jk - won't execute jsp or servlets > > > On Mon, 23 Dec 2002, Denise Mangano wrote: > > > Thanks to all your help, I've gotten over some bumps.
