Getting a page URL ..

[Sanket Sharma <sa...@gmail.com>]

Hi,

Is there a way to get the URL of a page with request parameters in REST
format? e.g. I have a REST scheme based on the following format
http://localhost:8080/products/categoryid/productid

Is there a straightforward way for creating URLs like this? I was looking
at PageRenderLinkSource - I see it has add parameter method, but what would
be the parameter name in this case? Moreover, that generates URL in the
form of query parameters. How do I generate a REST URL?

Also, what would be the best way to replace localhost/hostname for outgoing
links? Since the application will be running behind a
firewall/loadbalancer, the hostname will not be same as publicly visible
hostname.

I was thinking of reading the hostname/internet address from a properties
file and just appending the base path to it? Is there a better way of
achieving this?


Thank you for your help.

There's no need for URL rewriting just for that. You can simply set the
hostname and port via symbols:
        configuration.add(SymbolConstants.HOSTNAME, "www.myhost.com");
        configuration.add(SymbolConstants.HOSTPORT, "80");

Tapestry format, with page activation context, which you don't seem to  
know yet, is REST format already. Please read  
http://tapestry.apache.org/page-navigation.html, sections Page Render  
Request on, and the experiment with onActivate() and onPassivate().

Using PageRenderLinkSource.createPageRenderLinkWithContext(...) and pass  
the appropriate page activation context.

That's called URL rewriting, specifically outgoing URL rewriting. You can  
use the built-in LinkRewriter API. Google it. ;)

I think you can just add multiple context values to your page render link
like so.

@Inject
private PageRenderLinkSource linkSource;

Link link = linkSource.createPageRenderLinkWithContext(YourPage.class,
context1, context2);

String absoluteURI = link.toAbsoluteURI();

System.out.println("URL " + absoluteURI);
