Setting up Apache and Tomcat

[baden]

Hi All...

I'm in the process of building a new test/production server with Apache and Tomcat on Windows2K.

I've got the SSL working with Tomcat, and installed a JDBC realm using PostgreSQL. Works fine (and I'll post stuff on this on the Tomcat board later).

Then I go to install Apache Web Server. Installs fine.

Go to make the connection b/t Apache and Tomcat, doesn't work so fine.

I setup a virtual host (BindAddress * is set), with my system's name, when I type in

http://localhost

it redirects to my

http://<mysystemname>/index.html

- fine. But to access any anything on Tomcat I have to type

http://localhost

... and it's flaky.

Even w/o virtual host set it doesn't work.

I've uncommented the AJP stuff in server.xml, installed the mod_webapp.so and dll files... I just can't see what the problem is!

Here are my server.xml and httpd.conf files. The httpd is a little messy right now, ... well, here - can someone please throw me some info?

In addition...

I forgot to add that I'm pretty sure I had this working yesterday, but it's now hard to tell, b/c I don't know if I was looking at cached pages.

When I clear everything out, localhost brings up the Tomcat page, not the Apache index.html.

Sometines get Invalid packet 21 on loading localhost
Going to the examples/servlets page, none of the images show up, browser spinning it's wheels, and on trying to execute a servlet:
WebApp: Error 500
(File: pr_warp.c Line: 438)

Also get an error that &quot;Apache has generated errors and will be closed...&quot;

In my experience, I try to keep the following two lines the same:<br><br>ServerName localhost<br>#&nbsp;&nbsp;also tried this with my computer's name<br><br>#&lt;IfModule mod_webapp.c&gt;&nbsp;&nbsp;<br><br>&nbsp;&nbsp;WebAppConnection warpConnection warp profitma-tuobr3:8008<br><br>That means that you have the following:<br>[blockquote]ServerName localhost<br>&nbsp;&nbsp;WebAppConnection warpConnection warp localhost:8008[/blockquote]when you're testing locally or [blockquote]ServerName hostname.com<br>&nbsp;&nbsp;WebAppConnection warpConnection warp hostname.com:8008[/blockquote]when you're putting this up for others. <p>Liam Morley<br><A HREF="mailto:"></A><br>&quot;light the deep, and bring silence to the world.<br>light the world, and bring depth to the silence.&quot;

 

[carpeliam]

akk, that didn't work so well. [blockquote] isn't the right tag, apparently.. I meant to preview first ) I'm sorry. I'll show that one more time, just for clarity.

for local testing:

ServerName localhost
  WebAppConnection warpConnection warp localhost:8008

for production work when going public:

ServerName hostname.com
  WebAppConnection warpConnection warp hostname.com:8008

In addition, &quot;profitma-tuobr3&quot; looks a bit fishy to me. Is that the name of a public server? You need the fully qualified hostname in both places... best of luck ) Liam Morley

I seem to have gotten this thing to work, but a few problems still linger...


profitma-tuobr3 is the computer name I am doing this on.

I have made a few changes:

httpd.conf
==========
...
ServerName profitma-tuobr3
...
WebAppConnection warpConnection warp localhost:8008
# WebAppDeploy / warpConnection /ROOT
WebAppInfo /webapp-info
WebAppDeploy examples warpConnection /examples
# WebAppDeploy manager warpConnection /manager
WebAppDeploy webdav warpConnection /webdav
WebAppDeploy tomcat-docs warpConnection /tomcat-docs
ErrorLog logs/warpConnection-error_log.txt
ServerSignature Email

I tried the /ROOT line to try to get the servlet container to work - no good.

If I type

http://profitma-tuobr3/servlet/Servlet2

I get an error: Not Found - The requested URL /servlet/Servlet2 was not found on this server, but if I type

http://profitma-tuobr3:8080/servlet/Servlet2

it works. (this is for $CATALINA_HOME/webapps/ROOT/web-inf/classes/Servlet2.class)

Also, I guess you have to add the &quot;/&quot; at the end of any webapps you are trying to load from the URL line, or can this be changed, ie: &quot;

http://profitma-tuobr3/examples&quot;;

doesn't work, but need to add a &quot;/&quot; (examples has an index.html file).

I also commented out the manager deployment. It looks like this has to be called explicitly with port number, and cannot be run as a webapp from Apache. When uncommented, and typing:

http://profitma-tuobr3/manager/

comes up with the authentication, then a blank directory (there is not $CATALINA_HOME/manager). Doing a /manager/list returns an the following error: (I'M POSTING THIS IN CASE ANYONE ELSE HAS PROBLEMS WITH THIS)

Apache Tomcat/4.0.1 - HTTP Status 500 - Internal Server Error
EXCEPTION
javax.servlet.ServletException: Error allocating a servlet instance
at org.apache.catalina.core.StandardWrapper.allocate(StandardWrapper.java:619)
...
ROOT CAUSE
java.lang.SecurityException: Servlet of class org.apache.catalina.servlets.ManagerServlet is privileged and cannot be loaded by this web application
at org.apache.catalina.core.StandardWrapper.load(StandardWrapper.java:836)
...


Server.xml
==========

In the <!-- Define an Apache-Connector Service --> section,
I set name=&quot;profitma-tuobr3&quot; and added defaultHost=&quot;profitma-tuobr3&quot;.

I added the JDBC PostgreSQL realm to this section.



So back to the servlets question - why doesn't this work?

I am also writing a Windows install FAQ when this is all working and will post it here.

 

[carpeliam]

you won't get anything through Warp on profitma-tuobr3 if you have it set to localhost. You'll want to set that to profitma-tuobr3 as well, as in:

WebAppConnection warpConnection warp profitma-tuobr3:8008 Liam Morley
lmorley@gdc.wpi.edu
&quot;light the deep, and bring silence to the world.
light the world, and bring depth to the silence.&quot;

I got this to work finally - by using tomcat 4.0.2 and AJP. It won't work with 4.0.1 as the tomcat-ajp.jar in 4.0.1 does not have all the same files in it as the newer version does. I'll post an FAQ on the Windows Apache-AJP-Tomcat install as soon as I successfully test my load-balancing configurations.

Thanks all!
