Integrating Apache with Tomcat?

Anyone have a guide to integrating Apache with Tomcat using mod_jk?
I followed some guides online, but they all seem really dated with some obscure references. This seems like it should be on the top of the list....

Hi Alan.
I've discovered the exact same problem.... 0.0.0.0 instead of 127.0.0.1
You've obviously not had any replys here, but di you end up working it out on your own?

Apache with Tomcat cluster

Hi, I integrated Apache with Tomcat Cluster on Windows 2000. I instalated mod_jk2.dll, created workers2.properties and configurated server.xml in Tomcat instances. If I try to reach my .jsp file, e.g. http://localhost/root/main.jsp, I get follow message from Tomcat: source root/main.jsp is not available. What�s wrong? Can anybody help me? Apache version: 2.0.47, Tomcat: 1.4.27

Well, the first order of business is to determine exactly where main.jsp is located. If it is at <CATALINA_HOME>/webapps/main.jsp, then it should be at http://localhost:8080/main.jsp. Bypass Apache and verify that you can get to the Tomcat specific pages first.
Basically, we're trying to determine a) the correct URL and b) whether the problem is with Tomcat itself, or with the connections between Apache and Tomcat.
Essentially, we can't tell you where your configuration is incorrect until you tell us what your configuration is. :)

Adv. of using apache with tomcat??

can anyone pl tell me the advantages of using Apache with Tomcat in comarison to other web servers?
Thanks

The biggest advantages are that they are open source, so you don't have to pay a huge licence fee, and they are very stable. I don't know how they compare for speed - I know Apache is lightning when it comes to serving flat pages, there are no benchmarks yet for the new Tomcat because it was only released last monday. You can run them on linux or another unix variant, so they are more likely to be secure (windows servers are horrendously open to attack) and stable.

Tomcat vs Apache with Tomcat connectors (mod/jk)

Is there any advantage (security, performance etc.) of running a Java web application on Apache HTTP Server with Tomcat Connectors (mod/jk) rather than directly running it on Tomcat.

This question is already answered, see here:
http://tomcat.apache.org/faq/connectors.html
Also for Tomcat/ Apache related questions, post them to the relevant mailing lists.

Apache with Tomcat and dispatcher class.

I have a MVC design set up with a controller and dispatcher class. I am trynig to forward the results to a specific JSP. If I run the design completely within Tomcat, then everything works great. I have a tomcat site set up called /jsp. My servlet is within the jsp site. So if I do http://localhost:8080/jsp/mypage.jsp it will bring up the page fine. I then submit to and action of /myservlet?action=test. The servlet/dispatcher classes process and forward the request to "/jsp/mypage_result.jsp". All is fine and dandy.
However, when I try to run this through Apache first let the MOD_JK2 send the JSP/servlet requests to Tomcat the dispatcher doesn't work. I alway get the ERROR 404 page within tomcat (see note 1 below). Even if I use a "./mypage_result.jsp", because the pages are in the same directory, I still the get the error. Can anyone help?
What I think is happening is that when I make the inital request of http://localhost/jsp/mypage.jsp the request gets sent to Tomcat from Apache. Tomcat processes the jsp page and displays the result to the client. The user submits the data to the servlet (through Apache which pushes it to Tomcat). The servlet/dispatcher code runs and then gets ready to forward the request on. Where I get confused or I am completely guessing is that when the forward method gets called. Does it forward the request on as a HTTP request or as a request within Tomcat? I would guess it is an http request and the request comes in through Apache which (depending on the worker2.properties file) will or will not forward the request to Tomcat. This is where the problem happens. On this forward in the dispatcher class.
Please help.
NOTE 1:
HTTP Status 404 - /mypage_result.jsp
type Status report
message /mypage_result.jsp
description The requested resource (/mypage_result.jsp) is not available.
Apache Tomcat/4.1.24

After reading the documentation for the getRequestDispatcher method it seems that the file you are forwarding to must be in the same context. Well if it is in the same context within Tomcat, does it mean it is the same when I am trying to use Apache?
Anyone out there go this to work?
Thank you in advance for reading my post.

Integrating Apache with Oracle9iAS - How to?

Hi all,
I need to integrate Apache Web Server and Oracle9iAS, both running on different hosts. I'm aware that Oracle9iAS has built-in HTTP server based on proven apache server, but my client requires APache Web Server to be installed on separate host as a separate product and Oracle9IAS on seperate host and all HHTP requests should be redirected from Apache Web Server to Oracle9IAS.
Can any one guide me in achieving this integration?
Thanks in advance,
Aman

Thx for the reply!
The client is adament on using Apache web server with 9iAS since they already have apache web server running and now when they intend to shift to 9iAS, they dont want to modify their existing configuration but want the requests to be redirected through Apache.
Is it possible to configure 9iAS component - HTTP server on different host other than where app server is? or is there any plugin for Apache and 9iAS to interact?
How do I acheive this interaction when both are on 2 different hosts?
thx,
aman

Integrating Web server (eg Apache) with the application server

I am thinking a project in which I use more static HTML files than JSPs. One way is to use an Apache server to display those HTML files (it should be faster), and deploy the JSPs into the J2EE server; another way is just simple to change the web container�s port to 80 (of the PE 8), and wrap all the files into a war file and deploy it into the application server.
So can someone advise my which way is better? And if I use the first one, I�d like to know if it is the same way to integrate Apache with Tomcat.
Thank you very much!

In the past there has been a belief that the Apache web server serves static content faster than tomcat. Site managers would configure apache to deliver static content and integrate a web container to handle the dynamic content. I believe this argument is losing steam as tomcat gets better. I guess the only way you will know for sure is to deploy your application in PE 8.0 and then in an apache/web container configuration and do some benchmarking. I have no such benchmark data to compare and I base my comments on what I have read in newsgroups over the past months. Personally, I would opt for the app server only setup just to ease configuration. Others may have a different opinion.

I can't not star my tomcat.
what is wrong??
I have apache 2.0.50 and tomcat 5.0.25 on my Pc and before I add apache my tomcat work fine.
Thank you

Problems configuring XSQL with Tomcat

Having a lot of trouble getting this to work with tomcat standalone, apache with tomcat, and even apache with resin. (I have successfully gotten this to work with resin as both web and appserver.)
I have tried to be meticulous in following the directions, but one thing that is throwing me is that I can't find the web.xml file in my xdk distribution (neither in xdk8i nor xdk9i); I've attempted to create the .xsql extension-to-servlet mapping myself in Tomcat's web.xml file, but maybe I got this wrong.
The main symptom is that my xsql pages are basically being returned to me in the browser. Any help would be appreciated.

Bacically you need to create yourself, and here is an example:

Integrating Apache Web Server and Tomcat

Hi,
how do i integrate Apache Web Server (version 2.0) with Tomcat 5, on 2 different machines physically?
I have managed to integrate them on the same machine. Now, I need to separate the 2 into 2 different servers.
Please help.

This is a forum for Sun's Java Application Server.
Sun's AS is built on top of Tomcat and it's free in production (Platform Edition). The Standard Edition provides integration with an Apache HTTP server via a plugin.

Apache integrates with Tomcat

Hi, we have Apache 1.3.19 intergrated with Tomcat 3.2.2 using mod_jk.
When we checked with the mod_jk.log file, the file size is very large for just turning on it for 5 days. And the contents of this file are repeating the following two lines:
[jk_uri_worker_map.c (185)]: In jk_uri_worker_map_t::uri_worker_map_free, NULL parameters
[jk_uri_worker_map.c (335)]: jk_uri_worker_map_t::uri_worker_map_close, NULL parameter
Can somebody tell me what this two lines mean? The whole file is full of this two lines, nothing else.
Thanks so much in advance.

It's just logging from the Apache module which handles the protocol between the web server and the servlet container. Chances are your mod_jk configuration has its logging set higher than you want it -- if it is set to "DEBUG", try turning it down (or off, if you desire).
Good luck,

Client authentication with apache+mod_ssl+tomcat

Hello.
My question is a little bit off topic.
I try to read client certificates with request.getAttribute("javax.servlet.request.X509Certificate"), but the result is always null.
Probably it's null because I have nothing on the session. So my tomcat does not have the certificate. I use apache + mod_ssl + mod_jk + tomcat.
And here is my question: how did you configured apache and tomcat so that tomcat has the client cert ?
Thanks.

usually u generate a keystore for client, and mention that in ur SSL connector of tomcat
in apache, we need to configure things in ssl.conf

Apache with JServ or Tomcat?

What�s your preferences in relation with JSP web server: Apache with JServ module (or another want you considerer better) or Jakarta-tomcat?
I have used both, but I don�t know exactly which one I should use in my new job.
Thank you everybody and good luck!

JServ, while fine in its time, is now outdated and will not be updated. If you want to use any features added to the JSP or Servlet API's in recent years, you need to use Tomcat.

Discussion on Apache with Apaphe Tomcat

I am doing some research on the pros and cons of
either using Apache with Apaphe Tomcat on a live production server
or
Apaphe Tomcat on its own on a live server.
Anyone knows any urls to some documentation on the subject
Con (Apache with Apaphe Tomcat)
I personally feel that Apaphe Tomcat on its own is a better sollution
because the OS will use more memory to run both application (Apache with Apaphe Tomcat) simultanuesly.

I've heard on many occasions that Apache can serve static content (html) faster than Tomcat. So if you are not concerned with Java the you'd be better off with just Apache. Tomcats main focus is to serve dynamic Java content, it just so happens that it can serve static content as well.
here is one link,
