Dear Wiki user, You have subscribed to a wiki page or wiki category on "Tomcat Wiki" for change notification.
The following page has been changed by markt: http://wiki.apache.org/tomcat/FAQ/Connectors The comment on the change is: Add anchors - ran out of time for list of questions on this page. ------------------------------------------------------------------------------ '''Please note, jk2 is no longer supported. Please use mod_jk instead.''' == Questions == + - '''What is JK (or AJP)?''' + [[Anchor(Q1)]]'''What is JK (or AJP)?''' AJP is a wire protocol. It an optimized version of the HTTP protocol to allow a standalone web server such as Apache talk to Tomcat. Historically, Apache has always been much faster than Tomcat at serving static content. The idea is to let Apache serve the static content when possible, then proxy the request back to Tomcat for Tomcat related content. - '''Which connector: mod_jserv, JK, JK2, mod_webapp or mod_proxy?''' + [[Anchor(Q2)]]'''Which connector: mod_jserv, JK, JK2, mod_webapp or mod_proxy?''' * Stay away from mod_webapp, aka warp. It is deprecated and unsupported due to lack of developer interest and there are better options such as jk and jk2. It WILL NOT run on windows. * mod_jserv is unsupported and will not be supported in Tomcat 5. mod_jserv was the original connector which supported the ajp protocol. @@ -20, +21 @@ * mod_proxy. A cheap way to proxy without the hassles of configuring JK. This solution lacks sticky session load balancing. If you don't need some of the features of jk - this is a very simple alternative. * mod_proxy_ajp. With apache 2.2, mod_proxy was rewritten to support load balancing as well as a new transport called mod_proxy_ajp. This module is distributed with the Apache http server, not the Tomcat server. - '''Why should I integrate Apache with Tomcat? (or not)''' + [[Anchor(Q3)]]'''Why should I integrate Apache with Tomcat? (or not)''' There are many reasons to integrate Tomcat with Apache. And there are reasons why it should not be done too. Needless to say, everyone will disagree with the opinions here. With the performance of Tomcat 5 and 6, performance reasons become harder to justify. So here are the issues to discuss in integrating vs not. @@ -32, +33 @@ * Speed. Apache is faster at serving static content than Tomcat. But unless you have a high traffic site, this point is useless. But in some scenarios, tomcat can be faster than apache. So benchmark YOUR site. * Socket handling/system stability. Apache has better socket handling with respect to error conditions than Tomcat. The main reason is Tomcat must perform all its socket handling via the JVM which needs to be cross platform. The problem is socket optimization is a platform specific ordeal. Most of the time the java code is fine, but when you are also bombarded with dropped connections, invalid packets, invalid requests from invalid IP's, Apache does a better job at dropping these error conditions than JVM based program. (YMMV) - '''At boot, is order of start up (Apache vs Tomcat) important?''' + [[Anchor(Q4)]]'''At boot, is order of start up (Apache vs Tomcat) important?''' No. This way - either apache or tomcat can be restarted at any time independent of one another. - '''Is there any way to control the content of automatically generated mod_jk.conf-auto? I need my own specific commands added to it.''' + [[Anchor(Q5)]]'''Is there any way to control the content of automatically generated mod_jk.conf-auto? I need my own specific commands added to it.''' There really is no need to. Just copy the automatically generated mod_jk.conf-auto and edit it manually to your preference. None of production tomcat installations really use mod_jk.conf-auto as it is. - '''How do I bind to a specific ip address?''' + [[Anchor(Q6)]]'''How do I bind to a specific ip address?'''

You can't: you need to download the source and compile it for your platform. The source distributions are available from the [http://tomcat.apache.org/download-connectors.cgi standard location]. Note that JPackage.org has RPM distributions for the connectors as well as tomcat itself: [http://www.jpackage.org/ JPackage.org] - '''I'm having strange UTF-8 issues with my request parameters.''' + [[Anchor(Q8)]]'''I'm having strange UTF-8 issues with my request parameters.''' - Since tomcat 5 - does your connector have Connector declaration have URIEncoding="UTF-8".
