Re: Performance proxy_ajp vs. mod_jk when TOMCAT integration with Apache
Hi, Can somebody tell me what the difference between the proxy_ajp and mod_jk is. thanks, Christine --- Mladen Turk [EMAIL PROTECTED] wrote: Xuekun Hu wrote: Hi, From performance point, which connector will be used for TOMCAT intergration with Apache? proxy_ajp or mod_jk? I read some docs which said mod_jk should have better performance than proxying. While proxy_ajp in Apache2.1 is an addition to the mod_proxy and uses Tomcat's AJP protocol stack. So I ask the upper question. Right, both mod_jk and proxy_ajp have almost the same performance, and they are up to twice as fast compared with http mostly because of constant connection pool. AJP protocol gives it's share too by transferring less data across the wire. If you are using Apache 2.1+ there is no need to use mod_jk and maintain additional module.

Apache/Tomcat in-process
hi, Anybody knows how to make apache and tomcat are running in the same process? I read somewhere and said that it can be done but it is not easy. Anyone tried it? if so, please give me some pointers. thanks, Christine __ Do You Yahoo!? Tired of spam? Yahoo!

Connector for apache and tomcat
Hi, I am running the apache server 2.x and tomcat 5.5.x on RHEL4. I tried to setup the connector (JK1.2) between them and it didnt work. I know how to do the configuration on apache side. And I have documentation how to modify the Tomcat 4.1.x's server.xml file so that the tomcat can listen to the AJP13 requests. However, the jar files in tomcat 5.5.x is quite different from the ones in tomcat 4.1.x. I am not sure what needs to be modified in the tomcat 5.5.x's server.xml. Please give me some pointers how to do it. Besides the server.xml and workers.properties, what other things are required for tomcat 5.5.x to run on the connector? The integration between apache and tomcat is a must for my project. I cannot use just apache alone or tomcat alone. thanks, Christine __ Discover Yahoo!
