apache 1.3.19 in rh7.1;
tomcat 3.2.1;
i do not know whether i need to complier a mod_jk.so before i configurate both tomcat and apache, right now i only put the mod_jk.so,which download from jakarta.com, into libexec directory. then configurate the server.xml for connector in port 8009 with Ajp13Connector; then edit workers.properties for every items; include the mod_jk.conf-auto in place of tomat-apache-conf-auto
however, once the apache apachectl start after tomcat boot up; error logged in tomcat.logs.mod_jk.log and apache.logs.error_log both:
error_log:
no such fire or directory :error while opening the workers
(but workers.properties is actually available in the path which set in mod_jk.conf-auto);

Tomcat 4 - apache - mod_webapp problem

hi,
I know this is no tomcat forum, but i don't know where to post this message.
I'm unable to connect apache with my tomcat server.
I've installed apache(1.3.x) and tomcat(4.0 final) as stand-alone. they work fine.
I've added the mod_webapp.so and the following to my configuration:
--- httpd.conf ---------------------------------------
# WARP Connection to Tomcat 4
LoadModule webapp_module /usr/lib/apache/mod_webapp.so
AddModule mod_webapp.c
WebAppConnection warpConnection warp localhost:8008
WebAppDeploy examples warpConnection /examples/
--- server.xml ---------------------------------------
<Service name="Tomcat-Apache">
<Connector className="org.apache.catalina.connector.warp.WarpConnector"

<Realm className="org.apache.catalina.realm.MemoryRealm" />
</Engine>
</Service>
If I call http://localhost/examples
apache should forward this request to tomcat,
but apache says: "Not Found"
Can anybody help me, please?
ciao Markus

Try
http://localhost/examples/
Why?
Apache doesn't automaticaly add the slash sign at the end if it is not configured to.
Hint:
Install webapp-info also. Can be usefull sometimes...

Hi,
I'm working in a linux machine and choose to use also two different users. Of course I'm using two different ORACLE_HOME directories.I think that the best approach.Just a question ,are you keeping the "GROUP" same or different?

Tomcat and Apache via JK2

Hello,
Has anybody ever gotten tomcat and apache working properly? I'm having a hell of a time with it. I have them working independently, and have JK2 installed (made a package for it). I used the tomcat 4.1 package from incoming...
I can post configs and such if anybody thinks they can help. Right now, this is just a probe to see if anyone thinks they can help. I need a break from it, been scrapping with it for three hours now.
Once I get this working, I'll post a howto to the Wiki, I promise. :-D
Thanks for any info,
Dusty

Thanks for the info so far, it's still not working though... here's what I'm getting:
chane wrote:I might be able to help a bit. I have apache 2.x and Tomact 4.1.29 running with JK2.
I've got apache 2.0.48, tomcat 4.1.27, and jk2 2.0.2. Tomcat is from incoming, I built jk2 from ABS myself; It puts mod_jk2.so in /usr/lib/apache.
in httpd.conf added a module:
LoadModule jk2_module lib/apache/rh72-2.0.2-mod_jk2.so
I've got:
LoadModule jk2_module lib/apache/mod_jk2.so
I think that's right; it seems to be loading the module (see error messages below)
in the same directory (as httpd.conf) there is the workers2.properties file:
I've tried various versions of that file. I just tried it with the one you gave copy-pasted into place, same problems.
In the tomcat server.conf there is a connector for Coyote/JK2 AJP 1.3, make sure this is not commented and is on port 8009.
I think I've got that set up properly. Isn't there some command I can use to test if there is a service running on port 8009?
Anyway, when I go to http://localhost:8080/examples/jsp, for example, it works with tomcat. But if I go to http://localhost/examples/jsp I get a 404 not found; apache isn't forwarding the request to tomcat, for whatever reason.
In /var/log/httpd/error_log, I've got this info:

I can't tell if it isn't finding workers2.properties in the right place (why look in /usr/conf), or if its looking in two places and then not finding the shm file??
Do you have anything in ${TOMCAT_HOME}/conf/jk2.properties? All the stuff I've seen online wants me to add stuff to that file, but its never the same stuff.
Thanks very much,
Dusty

Tomcat vs APache

I have a few questions I've looked for in the apache and tomcat documentations. The moer I read the more I get confused
1) Can tomcat be used as a stand alone server?
2) Why should anyone integrate tomcat with apache?

1) Yes you can.
2) If my knoledge about tomcat is correct it is not properly optimized for static content. So normally you put tomcat behind an apache server and set the apache handle the ststic content. and tomcat to handle dynamic content.
That way you can also get some load off from the tomcat too
Also tomcat can be intigrated to already existing apache servers to enable servlet/jsps in the server.
Someware I saw an artical about tomcat being intigrated with IIS to allow servlets in it.

Why integrate Tomcat with Apache?

What's the reason to integrate Tomcat with Apache? What are the benefits?

Apache is way faster and more scaleable than Tomcat.
So if your website provides also static content (pages, pictures) etc this would be the reason.
Additionally if you have other technology to include, that Tomcat cannot handle (PHP for example) you would do this with Apache, too.

Tomcat or Apache?

I'm developing a Web Application using java and Tomcat. But, when I finish my application should be in Tomcat or Apache.
Or is it the same between both thecnologies?

You wont have any luck running anything in java with apache alone.
Tomcat is a servlet engine made specifically for java. you can
connect the two so that all static pages are vended by apache and
all java related requests are sent onto tomcat, but its hard to
configure. I suggest you run tomcat as a standalone.
to answer you question, your webapp needs to reside in tomcat.

Problem in configuring tomcat and apache

I am using mod_jk to configure tomcat and apache. In the server.xml file in /TOMCAT_HOME/conf, I have added this line:
<Listener className="org.apache.jk.config.ApacheConfig" modJk="/TOMCAT_HOME/mod_jk/mod_jk.so" />
And when I restart the tomcat, I get this error:
Caused by: java.lang.RuntimeException: Unable to create path to config file :
/usr/local/tomcat/apache-tomcat-5.5.15/conf/auto/mod_jk.conf
What this error is and how it will be removed. Any suggestion?

Seems like a filesystem user rights problem. Perhaps tomcat is running as a seperate user and this user has no rights to write to one of the subdirectories?

Upgrade the default Tomcat and Apache

Hi
Is there a working and correct way to upgrade and run a Tomcat and Apache server of your pick instead of the pre installed versions in OSX 10.4.8 server.
Meaning that i want to start and admin them throught Server Admin interface, and making Jboss notice the new Tomcat aswell.
Mikael

If you're asking here, the answer is probably no.
It is possible to build and install later versions of all the Mac OS X Server-bundled apps, including Apache, Tomcat, postfix, bind, etc., etc., but in most cases once you do you lose the ability to drive them via Server Admin.
Server Admin knows what it knows - more importantly it doesn't know any of the features of later versions of the apps (it may work with point released (e.g. Apache 1.3.20 -> 1.3.30, but it won't work with major versions like 1.3 -> 2.0).
So if you go that way you're on your own as far as configuring and maintaining the service is concerned.
Leopard (10.5) will include later versions of these apps if you're prepared to wait.

Tomcat and Apache/Tomcat is the same?

Hello,
I�m new to jsp and somedays ago I asked here a question and the solution was about installing Apache or Apache/Tomcat.
Now, my question is the following.
When I started to learn jsp , what I did were to install Tomcat. After reading some questions in these forums I do not know what is the difference between the installation of Tomcat and the installation of Apache/Tomcat.
What I have done for the moment is to have a server with Apache and another server for my jsp pages with Tomcat....
Does it means that it is possible to integrate two installations in only one server and to run all the pages in the same server? Where can I find information about that?
Thanks a lot and regards,
Patty

Tomcat has an HTTP listener built in, so you don't necessarily need Apache to run Tomcat and serve up HTML, JSP, and servlets.
But if you want to have Apache handle static HTML and forward servlet/JSP requests to Tomcat, there are docs at the Tomcat site to tell you how to bolt Tomcat onto Apache.
The Wrox book "Professional Apache Tomcat" has good instructions, too. I've done it successfully many times. - MOD

Apache 2.0 and Tomcat 4.1 (help)

I have spent the last few days trying to serve JSP's using Apache 2.0 in conjunction with Tomcat 4.1 with zero results. I am rather frazzled and am about to abandon the thought of using anything Java for a long time.
I have found several resources that have spun me around in circles and provided little to no help at all. I am using a Win98 box by the way...
My installations are as follows:
Apache 2.0 - C:\Java\Apache
Tomcat 4.1 - C:\Java\Apache\Tomcat_4.1
mod_jk.conf - C:\Java\Apache\Tomcat_4.1\conf\auto\
workers.properties - C:\Java\Apache\Tomcat_4.1\conf\jk\
httpd.conf - C:\Java\Apache\Apache2\conf\
mod_jk.dll - C:\Java\Apache\Apache2\bin

Web Service client running on Tomcat behind Apache-ModJk

Hi all.
I've realized a web service, which have been deployed on a Tomcat 5.5 instance running behind a firewall.
The Web Service is published through an Apache 2.0 Web Server, which is in the DMZ and which is connected to Tomcat via modjk.
Everything is working fine (as apache forwards to tomcat clients' calls), except from one thing: one of the web-methods needs to connect to a remote server to validate some data... that is, this web-method implements a "web service client" piece of code, by which a remote validating method must be called.
So, the problem is that this remote method must be accessed from something running behind the firewall...
One way could be to open a hole in the firewall, allowing only calls to that remote address, but I'd rather avoid this.
Do someone have other suggestions?
Is there perhaps any way to use mod_jk also for "exiting" and not only for "entering"?
Any help will be very appreciated!!

Could you not use a proxy server. The web service client would go through the proxy server to the internet

Connecting tomcat to apache.

Hello, I seek help in connecting apache to tomcat.
I followed this guide
http://johnturner.com/howto/winxp-howto.html
I have
WinXP SP2 fully updated
Apache 2.0.55
jakarta-tomcat-4.1.31
j2sdk-1_4_2_11-windows-i586-p
mod_jk-2.0.55.so
everything I think is installed correctly, my Problem is, tomcat will not auto generate a mod_jk.conf as it is supose to.
Anyone have any advice?
thank you.

but the service block called by the servlet container to allow the servlet to respond to a request.And this method is only called after the servlet's init() method has completed successfully and this is what the documentation says.....
so any idea why it was causing the problem... Already answered. service() is supposed to invoke doGet() or doPost() or doPut() etc etc depending on the request. You overrode that to not do that anymore, so you had broken it completely.
Normally the only times anyone overrides service() is if they put ALL of the logic that would have otherwise been in doGet()/doPost()/doPut() etc etc inside service() instead. Even then, I would generally consider it bad practice to ever override this method.

Tomcat 4 + Apache 1.3.2 + mod_jk.dll?

Ok, I've installed Apache and Tomcat both, and I'm able to get them running separately fine, Now i'm trying to get them to run together.
My problem lies in that Tomcat 4 doesn't generate the .conf files that you generally modify and include in apache's .conf file in order to get them to run together.
I'm running on windows 98, but any help from anyone on how to get these 3 working together would be appreciated.

I found this in the server.xml file in tomcat:
The MOD_WEBAPP connector is used to connect Apache 1.3 with Tomcat 4.0
as its servlet container. This is built by following these steps:
- cd {TOMCAT-SRC-HOME}/connectors
- make
- (Edit "Makedefs" as needed for your installation)
- make
- su root
- cp connectors/apache-1.3/mod_webapp.so {APACHE_HOME}/libexec
- exit
To configure the Apache side, you must ensure that you have a
"ServerName" directive defined in "httpd.conf". Then, lines like
these to the bottom of your "httpd.conf" file:
LoadModule webapp_module libexec/mod_webapp.so
WebAppConnection warpConnection warp localhost:8008
WebAppMount examples warpConnection /examples/
Finally, modify the "defaultHost" attribute in the "Engine" directive
below to match the "ServerName" setting defined in "https.conf". The
next time you restart Apache (after restarting Tomcat, if needed)
the connection will be established, and all applications you make
visible via "WebAppMount" directives can be accessed through Apache.
Here's the problem.. there is no /connectors directory, and I can't find a precompiled version of mod_webapp.so either (plus It doesn't tell me how to compile in windows..)
Anyway, if anyone has a precompiled mod_webapp.so file (if that will work) I guess that's all I need? I'm still lost as to how mod_jk.dll fits in though. I thought I read in a few places that tomcat4 used this instead of jserv.
Anyone able to help me out more?
