That's right.

Now, I think it is better to maintain all content (static and non 
static) under the same roof (i.e. use the same URL space)

After all, you are building a web application. That application consists 
of dynamic content (.jsp, servlets) and static content (html, images). 
Why separate them? If you keep your application together it would be 
easier to manage it (backups, version control, relocation, etc.)

Tomcat can serve static content by itself, so you can put all .html and 
image files alongside your .jsp files. You can also instruct Tomcat to 
use the port 80. This would be the simplest setup and you would not have 
to worry about that :8080 in URLS. Here at work we use this setup for 
individual developer's PCs. So each developer has his own Tomcat server 
in his own PC.

We deploy our application in an intranet server. Since that server also 
uses Apache, there is a conflict with port 80. So we added another IP 
address to that server and make Apache use one of the IP, and Tomcat the 
other. So our webapp still uses port 80 and we do not have to worry 
about the URLs. This setup is still fairly simple.

If you cannot add a IP address to your server, or find Tomcat too slow 
for static content, you can still integrate Tomcat and Apache (using 
mod_jk), and make Apache serve the static content, and Tomcat the 
dynamic content using the same URL space. Since this setup proved to be 
cumbersome (at least for me) we sticked to the previous setup, since we 
did not encounter any performance problem serving our (relativelly 
small) static content with Tomcat.

Re: New ROOT

[Guillermo Labatte]

Look into the server.xml file. There you will find several Context 
entries. The ROOT context has the path element with value "" (empty 
string). Change the docBase  attribute of that context and use anything 
you like instead of ROOT. As far as I know the directory you use as 
docBase should be relative to webapps, tough. I think you can use a .jar 
file as a docBase, instead of a directory. Maybe someone more 
knowledgeable than me could enlighten us.

Re: New ROOT

[Guillermo Labatte]

mv /tomcatdir/webapps/ROOT /home/httpd/.
mv /home/httpd/ROOT /home/httpd/jsp
ln -s /home/httpd/jsp /tomcatdir/webapps/ROOT

should do the trick.

Tomcat (being a Java application) cannot tell the difference between a 
regular directory and a linked directory. So maybe you set the link 
wrong, or maybe there were a problem with the file permissions (i.e. the 
user under which Tomcat were running did not have the necessary 
privileges to access the /home/httpd/jsp directory or its files)

As far as I know, sendRedirect works at the HTTP level. In order to open 
a new browser window you need to operate at the HTML/JavaScript level.

Use something like openWindow() 
in your HTML code in order to open a new window without user 
intervention. Please check the exact syntax in your HTML/JavaScript manuals.

I'm just starting using Tomcat, so I don't know i this is the best, or 
recommended way, but at least it worked for me:

In $CATALINA_HOME/conf/servler.xml use



Note that the value for the path attribute is an empty String.

In Linux it goes to the file catalina.out in CATALINA_HOME/logs.

I use tail -f catalina.out in order to see the messages while they are 
written.
