Virtual Host Context Aliasing
I would think this would be a common question, but I couldn't find it
documented, nor asked on this list.
Very often domains are served from 2 urls (www.zzz.net & zzz.net) with the
same functionality. When I configure my virtual hosts in Apache's httpd.conf
this is easy:
<VirtualHost _default_:80>
ServerName www.zzz.net
ServerAlias zzz.net
DocumentRoot /home/httpd/html/zzz
<Directory "/home/httpd/html/zzz/WEB-INF">
Options None
Deny from all
</Directory>
JkMount /*.jsp ajp13
JkMount /servlet/* ajp13
</VirtualHost>
The following properly placed in server.xml creates 2 seperate contexts for
the same set of servlets and JSPs. Functional, but a little wasteful.
<Host name="www.zzz.net" >
<Context path="" docBase="/home/httpd/html/zzz"
crossContext="true" debug="0" reloadable="true" trusted="false" />
</Host>
<Host name="zzz.net" >
<Context path="" docBase="/home/httpd/html/zzz"
crossContext="true" debug="0" reloadable="true" trusted="false" />
</Host>
Now, I how do I do an alias Context in Tomcat's server.xml so that there is
only one Host/Context with multiple names??????
Thank you in advance.

I've tested it without any success. Unfortunately.
But exactly that's it what has been said in the tomcat-server-howto.
Is it a bug? It must be....

tomcat 4, I think :)
I have just tested it with version 3.2.2, and that gives the error:
bash# cat tomcat.log | grep Alias
At The element type "Alias" must be terminated by the matching end-tag
"</Alias>".
org.xml.sax.SAXParseException: The element type "Alias" must be terminated
by the matching end-tag "</Alias>".
At The element type "Alias" must be terminated by the matching end-tag
"</Alias>".
org.xml.sax.SAXParseException: The element type "Alias" must be terminated
by the matching end-tag "</Alias>".
I have not been able to find any doco related to this though :(

I have been told from a collegue of mine that an alias tag can be used.
I have not tested this though, let me know if this works :)
<Host name="www.mycompany.com" ...>
...
<Alias name="mycompany.com"/>
...
</Host>

Re: Virtual Host Context Aliasing

Hi Daniel,
I have the same problem -- wanting to alias more than one host name to a
single context. Unfortunately, there is no way to do this. I've heard that
the 4.0 version of Tomcat may have some abilities for doing this, but it's
not nearly as straightforward as Apache's ServerAlias directive.
For now, I've turned off zzz.net (using your example) in my DNS and am only
serving www.zzz.net. I do a lot of connection pooling and other shared
resources, so I can't afford to have 2 versions of all my contexts running
at the same time. This is a totally unsatisfactory solution, but it's my
only choice for the moment.
Thanks,
--jeff
