Custom Resource Implementation
Hi experts!
I've implemented a custom Resource with resource type "application/xyz".
The Resource is able to adaptTo ValueMap and InputStream.
A ResourceProvider with root "/demoprovider" delivers an instance with
properties "sling:resourceType":"application/xyz and
"jcr:primaryType":"nt:unstructured".
A request on "/demoprovider/something.html" will create a new instance of
the custom resource and render it via the StreamRendererServlet.
Now I implemented a sling render Servlet for "resourceTypes =
"application/xyz". But the request is always delegated to the
DefaultGetServlet.
What am I missing? Is there some example code? Do I need a custom
ResourceResolver?
Regards
Bernd

Ah, good to hear - you probably had some old stuff in there.

After recreating the sling.home directory it works now. Thanks a lot :-)

That won't work for subpaths - I just added an HTML rendering test of
our example Planet resources, at http://svn.apache.org/r1536699
You might want to compare with what you're doing, and/or run that test
in your environment to verify it (the test-services bundle requires
the org.apache.sling.junit.core bundle).

Doesn't help.

Yes it does.
I can try to map the servlet to the /demoprovider path. Maybe it helps.

Does your custom Resource's getResourceType() method return application/xyz ?
If not, I suspect the property with that name is not taken into
account for servlet selection.

Ok, so your servlet's setup is correct .

What does /system/console/requests say in that case?

Re: Custom Resource Implementation
Posted by Bernd Winterstein <be...@winterstein-web.de>.
Hi Bertrand
Thanks for your answer
I created the following node:
{"title":"Demo","sling:resourceType":"application/xyz","jcr:createdBy":"admin","jcr:created":"Tue
Oct 29 2013 08:54:58 GMT+0100","jcr:primaryType":"sling:Folder"}
When I call it via the registered extension e.g. /content/xyz.do I can
verify that my servlet is called.
TIMER_START{ServletResolution}
TIMER_START{resolveServlet(JcrNodeResource, type=application/xyz,
superType=null, path=/content/xyz)}
TIMER_END{0,resolveServlet(JcrNodeResource, type=application/xyz,
superType=null, path=/content/xyz)} Using servlet
de.cloudsurfers.slinTIMER_END{0,ServletResolution} URI=/content/xyz.do
handled by Servlet=de.cloudsurfers.sling.renderer.DemoRenderer
But via /demoprovider/xyz.do it is always rendered via the
DefaultGetServlet.

Did you try creating a JCR node with that resource type, to verify
that your servlet is called?
I suspect it's not, because apart from that your setup looks correct.
You might want also to check /system/console/requests to see exactly
what's happening.
We have a simple example ResourceProvider at [1], you might want to
try with that one and see what's different.
