Re: Included port numbers in web links e.g. 8080

[Mark Lowe]

Thats quite weird.. what about switching the catalina server off in 
server.xml? We use apache and tomcat with jk and never had this.

Yes, that works.

If you are getting links with 8080 in the urls then my guess
is you're
not requesting pages over port 80 but 8080.
Requests that cause a problem are initiated by redirects. For example:

 <logic:redirect forward="welcome"/>

So the first question is, is mod_jk working? and how do you know this?
I would assume it is functioning fine as all the defined Location's 
forward
to Tomcat appropriately. Am I missing something?

For example, this is our site:

http://www.objectdomain.com/

when the above is entered, the index.jsp is encountered that contains 
the
redirect. This results in the following URL:

http://www.objectdomain.com:8080/welcome.do

Note, if you manually remove the port from the above URL and resubmit 
the
request, the port is not re-inserted until it encounters a link with a
forward (most, but not all, of our links are currently simple HTML 
links,
not forwards).

Okay.. "Struts " doesn't do this at all but the http server catalina,
conveniently bundled with tomcat  does .. (I think i've got the
catalina thing right) .

You better go over the problem again, when you request a *.do over
port 80 the links render with :8080 or do i not understand?

We have Tomcat running behind an Apache HTTPD and we are
getting the
port as
well. Is there perhaps something we are missing in the
configuration?

What connector are you using mod_jserv? mod_jk?



If you've got a
different situation,
you'll need to figure out how to tell your servlet container
to adjust the
server port it reports -- there's nothing Struts can do to help.
If configuration is not the solution, any suggestions on
how to go
about
changing the reported port?
To my mind, it is not so much that we want the servlet
container to
report a
different port (after all, it is using that port), we just
want struts
to
use a different port (80) for links. That is, we want to
ensure routing
through the front door (i.e., Apache). Would using a Filter be a
possible
solution?
If apache and tomcat are running on the same machine then
there should
be no issue, it will be a matter of having request for *.do, *.jsp
being mapped to the connector module.

Quoting "Gabriel W." <[EMAIL PROTECTED]>:

Hi,

I am relatively new to this list so I do not know if this
topic was discussed
before (I checked the archive and it does not appear that way).

It seems that Struts includes the ServerPort in web links
if not of the
values 80 or 443 (e.g. http://mydomain.com:8080). In some
cases this is not
the welcomed behavior.
Specifically if the Struts server is listening on Port
8080 behind a
firewall. The firewall receives the request from the outside
internet on port 80 and routes it to the machine listening
on Port 8080.
The Struts machine in this case does not know the
difference and so includes
the Port 8080.

I looked at the Struts source code I assume is behind the logic
(org.apache.struts.taglib.html.BaseTag), and it
does not appear as though there is a configuration flag to
turn this logic
on/off.

Are there any considerations for such an option in the
future so that a
firewalled site won't have to show 8080.

NOTE: This is a situation where the Struts server does not
have permission to
listen on Port 80.

Regards,
Gabe
Struts is basing its decision on the port returned by calling
ServletRequest.getServerPort() -- in other words, if you've
got a server or
proxy that receives requests on port 80 and internally
redirects them to some
other port, there's absolutely no way that Struts can know
what the right port
number is unless your servlet container can tell it.
For situations like Tomcat running behind an Apache HTTPD
server, this normally
gets taken care of you automatically.  If you've got a
different situation,
you'll need to figure out how to tell your servlet container
to adjust the
server port it reports -- there's nothing Struts can do to help.
