Hi gurus,

Here I got a problem to solve. There are two domains on my web server (e.g. domain S and domain W). Domain S will use the JSPs on application server.

Let's assumed I have a new form placed on application server and I wanna make use of those images and stylesheets on web server.

Is there any way I can configure in my apache and tomcat, so that I can do the followings?

e.g.
Types                  Availability
html                  Domain W
jsp                  Domain S

jpeg                  Domain W & Domain S
css                  Domain W & Domain S
js                  Domain W & Domain S


If so, what files I have to configure? I knew there are some XMLs but i am not too sure.

Thanks for your help.

Greetings,
With their default configuration, apache will listen on port 80 and Tomcat on port 8080. Casual web users will access port 80, as that's the standard port for web traffic.

The usual way to handle you situation is to setup two virtualhosts on your apache server, one for each domain, and to tell apache to proxy requests to your JSP files to your tomcat server.

See snippet below for sample config. What this does is setup your apache server to answer requests for both domains and server static files from /var/www/html/domain-s or /var/www/html/domain-w depending on the domain being accessed. Additionaly, any request path that starts with /jsp to domain S will be forward to the tomcat server transparently to the user.

If this does not meet your needs, please let me know and I'll address your concerns.

Regards,
Christophe
NameVirtualHost *:80
 
<VirtualHost *:80>
    ServerAdmin webmaster@domain-w.com
    DocumentRoot /var/www/html/domain-w
    ServerName www.domain-w.com
    ErrorLog /var/log/httpd/www.domain-w.com-error_log
    CustomLog /var/log/httpd/www.domain-w.com-access_log combined
</VirtualHost>
<VirtualHost *:80>
    ServerAdmin webmaster@domain-s.com
    DocumentRoot /var/www/html/domain-s
    ServerName www.domain-s.com
    ErrorLog /var/log/httpd/www.domain-s.com-error_log
    CustomLog /var/log/httpd/www.domain-s.com-access_log combined
    ProxyPass /jsp http://localhost:8080/jsp
    ProxyPassReverse /jsp http://localhost:8080/jsp
</VirtualHost>

Hi Christophe,

Thanks for your information, it helps me a lot!

As there are several XML files for Apache and Tomcat, they look quite similar but I am wondering if I have to modify all those serverl.xml / web.xml.

Thanks for your help again.

Cheers,
Manfred

Assume here's my case.
1.      s-stuff https://s-stuff.MySite.com (secured stuff with JSP from application server)
2.      www      http:/www.MySite.com (mainly static stuff like html and images, etc)


If I'm browsing a page through https (e.g. https://s-stuff.MySite.com/abc.jsp) and there are some images for navigation menu.

Would these images derived from https://www.MySite.com/images/menu1.gif or http://www.MySite.com/images/menu1.gif?
