Re: Apache 2, Tomcat 4.1, RH 9 - servlet/jsp requests return only on second hit
At 09:18 AM 2/10/2004, Brent Parker wrote: My Config: Redhat 9, Apache 2.0.47, mod_jk 1.2.6, Tomcat 4.1.29 It takes a second request (to port 80) to get a jsp or servlet output to display in the browser: I type in the url (jsp or servlet) and hit Enter, the browser (Mozilla and IE) spins indefinitely. I then highlight the address line and hit Enter a second time, and the page will immediately load. Restated: All servlets/jsp requests do load - but only on the second hit (request). However, any static html page (served through apache) loads immediately on the first hit. I had this same problem and never could find a fix... I reverted back to 1.2.5 of the connectors and all was fine. -Dave The println's I put in the jsp/servlet reveal that they are getting hit on the first request, and they print out repeatedly (thus the browser spin) until I make the second request. To isolate tomcat: If I configure the server.xml, and hit the jsp/servlet through port 8080, it serves immediately. Maybe this isn't a tomcat problem, but since it does involve tomcat, I figured this forum would have the best shot at an answer. The apache (access_log, error_log), mod_jk, and catalina logs do not show any errors. The catalina_log.*.txt shows sporadic IOException Broken pipe errors. Any suggestions / advice would be appreciated. I suspect I have configured something wrong - I would be glad to forward/post my config files if it would help. I have been writing java apps for a couple of years - some deployed to tomcat standalone, but this is my first adventure into tomcat connected to apache. Thanks!!

Load Balancing and Sticky Sessions with mod_jk2
I've been playing with this all day. One Apache 2.0.47 machine with jk2 wanting desperately to talk to two tomcat servers. I started this days adventure with mod_jk only to read that sticky sessions wouldn't work with a non --enable-mpm=worker compiled version of apache. (is this true??) I then recompiled apache and mod_jk2 but the configuration syntax is different. in mod_jk land it would something like: worker.tomcat1.port=11009 worker.tomcat1.host=localhost worker.tomcat1.type=ajp13 worker.tomcat1.lbfactor=100 worker.tomcat2.port=12009 worker.tomcat2.host=localhost worker.tomcat2.type=ajp13 worker.tomcat2.lbfactor=100 with the corresponding jvmRoutes and port changes added on the servers. I guess I need an someone who is using different machines for web and tomcat with an example workers2.properties they could email to help me along or some one to answer a question or two. How do I do a worker.type=loadbalance in jk2 syntax? How do I write the correspondiong entries into the workers2.properties file to tell apache about my two tomcat servers and to share the .jsp load between them?. TIA -David Obrien
