SVG, servlet filters and interception
Hi, i want to use svg in my webapp, since it makes it easy to create images on the fly. My plan is to make t5 pages that output svg instead of html, which should be easy. But alas svg is not as straigh forward as it should. Little browser support might force me to convert the svg to images on the server before they are streamed to the client. That also means that the image is fetched in a different request than the request for the page. I also have to convert the response (using batik) to a png. Any ideas where i put the interceptor to achieve this? Is it possible to use "normal" pages in request for i.e. images this way? (That way i could also define svg images as background in css) any help is greatly appreciated. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

As described in TAPESTRY-2519 you need to override the service
ClasspathURLConverter. Something like that:
public class MyClasspathURLConverterImpl implements ClasspathURLConverter
{
public URL convert(URL url)
{
if (url.getProtocol().startsWith("bundle"))
{
//return a valid java url here
}
return url;
}
}
This will let you load the page classes within OSGi container.
To contribute OSGi Services to Tapestry, you have to wrap them by
org.apache.tapestry5.ioc.def.ServiceDef. Please see how tapestry-spring
module does it.
There are still further challenges, but I guess you want be able to start a
hello world page first. :)

Hi,
i am currrently trying to integrate tapestry into an OSGI container using
apache felix and the ops4j pax web service. (For many interesting reasons,
one of them is the possibility to add services to the webapp at runtime...)
I have managed to register the Tapestry filter, and load my app module, the
builtin modules are also loaded at startup.
But i am not able to load my pages, the request just falls through and ends
up with my registered default servlet.
I have tried to locate the code that bootstraps the pages and components to
see if there is some error in locating or loading the page classes in the
.pages package, but i have not been able to find the code that initializes
the pages.
Could someone with intimate knowledge of tapestry give me a hint to where
the loading of pages is performed initially, so i can check for myself?

Excellent and thank you for the reply, now i have a starting point, and
a clue to continue the integration.
