Hi guys,
Many thanks for your suggestions! The resource providers are indeed
very useful for some part of my work. As you already mentioned it's
basically the solution to unify the external data with some existing
node tree structured data.
@Olaf: The idea of NEBA is really nice. Though I'm not using it
directly, I found some of its interesting points that can be applied.
Cheers,
Duy

Hi Duy,
+1 for using resource providers. It is also the recommended approach for
integrating third-party data sources - if you intend to leverage Sling's
resource resolution and -rendering for the views. If that is not the case, I
would say it does not make much sense to use Sling - after all, you would
bypass almost all of its core features and merely use it as a middleware
platform.
Another option is to use NEBA (http://neba.io), in which case you can use
Spring MVC (http://neba.io/userguide.html#springmvc), which would make the
path-based parameter extraction significantly easier. I don't what you
external data sources are, but in case it's relational, you could then also
use Spring's JDBC templating or ORM abstraction to access that data.
Kind regards,
Olaf

Hi Duy
You may want to implement a ResourceProvider. It allows you to hook an
arbitrary resource subtree into Sling's resource tree backed by your won
logic. For the read-only case that's not even very complicated.
Bertrand created a PlanetResourceProvider example some time ago[0].
That may be helpful.

For some reasons (large data set, continuous changes in the original
data, etc.), I'm not motivated to import the whole external data into
the node tree structure.
You're right that the universal servlet solution seems to be the very
last choice, but I couldn't find any other way without importing the
data.
Any other advices are very welcomed!
Thanks,

So in my naïve response to your situation. I don’t see the problem with
mapping directly to the resource model, the first thing I would do is to
import the information into the node tree structure. The exact structure
isn’t really important as long as it mirrors the intent of the request.
/content/document1
/content/document2
/content/document2/true/version1
/content/document2/true/version2
Then for each level where a file should be returned uses a sling
sling:resourceType that returns the file.
If you have restrictions, like you know the name of the file but the
versions of the file are maintained separately and you don't have an
ability to import.
You can have a node structure like
/content/{document}/true
With the sling:resourceType for the document retrieving the document in
question and the resourceType for true locating the version that's being
requested.
If you don't know the document ahead of time, then you're back to a very
generic servlet interacting with another system. I would still avoid the
universal solution and look to implement something very specific for these
types of requests, based an identifier for the service.

Hi,
Sorry for the formatting error, as there were 3 different urls actually:
/myhost/{documentName}
/myhost//{hasRevision}/{revisionID}
/myhost/-/users/{userName}
* So in your example, it is like:
/host/whitepaper
/host/whitepaper/true/version-1
/host/-/users/john123
(I avoid .pdf as it can be misleading to a selector which is not the
idea of my question)

Hello,

I'm bringing here a use case in Sling and look forward to receiving
some opinions from the community.

I need to write a server-side app that serves customized RESTful
APIs for a client app (which is stable and the set of APIs is
fixed). The problem comes from ugly API urls that can hardly be
mapped into the resource model of Sling, for example:
=20
*/myhost/{documentName}/myhost/{**documentName*
*}/{hasRevision}/{revisionID}/myhost/-/users/{userName}*

Especially properties like =E2=80=9CdocumentName,
=E2=80=9CrevisionID a=
