Subject: Re: Questions about Tomcat and Apache Integration? From: "Jack Gao" <[EMAIL PROTECTED]> === Nobody has interests with it?
Well, maybe I should give more information. I believe somebody must have interests with it also. I tried to use mod_webapp, but since I can not get apache and tomcat build successfully on my Windows 2000 box, I used precompiled mod_webapp with Tomcat 4.0.1. But it worked very unstable, so I go to mod_jk. mod_jk worked perfect to me. But then I got this question. Now I did more test and research on it, here is what I got. To avoid apache pass all request to Tomcat, I need to add something like this into mod_jk.conf (which will be included in httpd.conf of apache.) JkMount /myapplication/*.jsp ajp13 JkMount /myapplication/servlet/* ajp13 This is what mod_jk how-to document suggestion. So it will only forward request for jsp and servlet to tomcat, and all the others (assume to be static resources) will be handled by apache. So far so good, but it's for Tomcat 3.x, not Tomcat 4.x. Because with Tomcat 3.x, all servlet will go to servlet directory, but with Tomcat 4.x, by default it will not. So, a URL like http://xxxxx.xxx.xxx/myapplication/list is very possible to be request of servlet. How can we handle it? We had to use: JkMount /myapplication/* ajp13 This will forward all the request to Tomcat, then we got this static resource problem again. So, maybe we need to keep using "/servlet" for all servlet request in order to use mod_jk. I don't know if mod_webapp.so resolved this kind of problem, because I can not found document on it. Any commons, suggestions, notes even a link to some documents are welcomed.
