Subject Re: Difficulties with Virtual Host in the Apache + Tomcat
Date Fri, 17 Jan 2003 21:09:18 GMT
   I am also very confused with whole the process of 
configuration of the Apache, after the initial problem of 
the integration of the Apache with Tomcat in Linux.  
   I have faith that some points need to be lifted up:

"you only need the same four hosts configured in Tomcat 
is you want to have
different docBase's or different explicitly defined 
contexts (or other components)"

The Apache + Tomcat will be the server web of four 
applications that are being developed  
inside of an university of Brazil, meantime without 
commercial ends. These applications  
they will have functionalities totally different some of 
the other ones, what justifies the  
adoption and creation of four virtual hosts, each one 
with a different path. Therefore,  
it is necessary that the same happened, regarding the 
Apache, in the tomcat for the storage of the classes java 
and of the  
files jsp properly said. We already know that that is 
possible then it is a point the   
minus of concern.

"I would certainly try to make index.jsp produce valid 
HTML for your tests.
You also might want to have a WEB-INF folder w/ a web.xml 
in /web/ged."

The file index.jsp that I am using, was a file of tests 
very used  
for us in the last year, when we used the Caucho Resin, 
and the same worked  
perfectly in Resin after the end of the configuration of 
the server in subject, printing  
in the window of the navigator the following message: 
Like you he must have noticed for the own signature of 
all my e-mails, mine  
area is the one of database, more specifically database 
Oracle. I am beginning  
now to work with development for the web and I am being 
hit a lot of the configuration  
of the famous tomcat.  
How don't I understand a lot of tomcat thing which the 
advantage of having web.xml in the / web/ged/WEB-INF?

"I'm confused by your httpd.conf - first, you don't need 
the Include
directive if you have all the Jk directives manually 
defined in httpd.conf."

Lajos, now who was confused went me. I accomplished the 
whole installation process  
basic of the Apache 1.3.27, Tomcat 4.1.18 and the mod_jk 
following the instructions  
of his/her tutorial Galatea FlashGuideTM: Integrating 
Apache 1.3.x - Tomcat 4.x on Unix,  
and during the mod_jk I was forced to use "Alternate 
build process  
it goes", tends in view that the "Building 
mod_jk" didn't work in my atmosphere.  
After the installation of the Apache, Tomcat and mod_jk I 
left for the   
"Configuring Apache with the Jk directives", following 
the three described steps.  
What really happened with directing Include, it was that 
I had an interpretation doubt  
in his documentation. For the that I could notice now, 
after his e-mail is that or I use  
Include or I use what is described in "Configuring Apache 
with the Jk directives."

"Second, your <IfModule mod_jk.c> block should come 
before the virtual host block.
However, I can't say that either of these two issues are 
the root cause of
your problem - everything else looks good."

When in Galatea FlashGuideTM: Integrating Apache 1.3.x - 
Tomcat 4.x on Unix, you said  
that it was to put him/it <IfModule mod_jk.c> block in 
the end of the file httpd.conf found  
that it went in the last lines of the file.

Lajos, accomplished all of the suggested changes:  
1 - I removed the directing include  
2 - I passed the terms below for before NameVirtualHost

<IfModule mod_jk.c>
JkWorkersFile "/usr/local/jakarta-tomcat-
JkLogFile "/usr/local/jakarta-tomcat-

JkLogLevel debug

JkMount /examples ajp13
JkMount /examples/* ajp13

3 - I changed the docBase of the <Context> for /web

Now, trying to access the servant, I receive the 
following message in

HTTP Status 500 - No Context configured to process this 


type Status report

message No Context configured to process this request

description The server encountered an internal error (No 
Context configured to process this request) that 
prevented it from fulfilling this request.


Apache Tomcat/4.1.18

It lets me to ask a thing. Starting from the moment that 
I include my own host in the  
server.xml, as shown in my first e-mail, I need to remove 
of the configuration  
of Tomcat the <Host name = "localhost".... that has soon 
above, in other words, the host that  
does it come for default in server.xml?  
You have some other suggestion of what to do, who knows, 
if it is possible of his part  
I can order you server.xml or httpd.conf.  
I thank the help of all a lot you.
