Generate URL
Hello,
I want to generate an URL to an IPage or an IExternalPage from a regular
java class. It's from a JSP project, so I don't have a request cycle that I
can use to construct a URL. And I can't use the JSP tags in Tapestry because
I have to have the URL in a variable, and not written out on the page as it
is in the taglib.
The way I do it know (for the IPage) is with a function like this:
public static String getPageURL(HttpServletRequest request, String
pageName, String servletPath) {
String scheme = request.getScheme();
String host = request.getServerName();
int port = request.getServerPort();
String contextPath = request.getContextPath();
return scheme + "://" + host + ":" + port + contextPath + servletPath +
"?service=page/" + pageName;
}
But that function is not very dynamic and if I want to use OGNL expressions
in a similar call to an IExternalPage I have to duplicate a lot of code from
the taglib code. Is there some other way?
Best regards,
Niklas Ekman

That is in general what I'm doing with the basic
IPage. But with the external page with it's parameters
(prefixed with S and other things) I hoped to use some
nice, clean Tapestry technique for doing this a bit
easier. I remember that the service URL:s changed
quite a bit over the versions, and I thought that I
could eliminate that in some way.

Woah, yeah, that is ugly.
You can ask the various services, like ExternalService, for the URL,
but you'll need some Tapestry-specific context to do so.
I don't have a more clever mechanism in mind at this point. As long as
you have the base URL to your Tapestry application somehow, you can
simply append ?service=external/PageName - which isn't too bad of a
hack.

I've done that... and I discovered that the procedure
for doing the stuff is by using the dispathcer and
making an include on the current output. I don't know
how to use the same technique in some other way.

Look at the source code for the taglibs :))
