JSTL - printing the current host url

[Christine Mayer]

I want to dynamically output the hosts url - e.g. "http:/
www.myurl.com/" using a JSTL tag.
I tried several things, but didn't get it to work. I read the J2EE API
and found request.getRemoteHost() which might be what I need (not
sure, because on my local pc it returns 127.0.0.1 istead of
"localhost"), however,

<cut value="${remoteHost}"/>

did not work.

Any idea what's wrong?

More info:

Hi, I want to create a link to send the current url by email. However,
I am also using urlrewrite, so I cannot take the real url. Therefore I
have a parameter "currentUrl" that gives me the current url - however
I don't want to statically include the host's adress, I would like to
add it dynamically, so it must be something like:
<cut value="${remoteHost}"/><cut value="${currentUrl}"/>

Thanks in advance,

Christine

Maybe ${request.remoteHost}?

But that's the wrong property, if by "the host" you mean the app server host.

getRemoteHost()
Returns the fully qualified name of the client or the last proxy that sent the request.

Use http://${pageContext.request.remoteHost}:${pageContext.request.remotePort}
for the server name and port. In order to get the base page URL, you
will need to use ${pageContext.request.requestURL}. however, if you
are using Struts and the the URL is something like /processRecord.do,
you will end up getting the name of the actual JSP being served
instead of /processRecord.do.

Except that getRemoteHost() returns the /client/, not the /server/.

Oops! My bad. ${pageContext.request.serverName} should work.
