Read Sling resources remotely
Hi,
Can we access sling resources from a java client ? Is there any
sample/links to refer ?
This is just to test the Cassandra impl on Sling. Now the Cassandra bundle
is installed in sling server. There is a documentation on editing the JCR
content through SlingPostServlet. Can I call this servlet and test my
resource provider ?

Thanks

Ugh, I meant @Service. But the annotations seem to be set up properly
on the CassandraResourceProvider [1]

You haven't set up any execution of the maven-scr-plugin, so it's not
getting invoked. See [2] for how it should appear . Something like (
excuse the indentation ):

@ServiceProvider is the right one to add, but IUUC you also need to
add @Component . See the maven-scr-plugin docs [1] for more details.
I can't remember where your code is posted, can you please paste a
link? Perhaps the maven-scr-plugin is not properly integrated in the
build.

Re: Read Sling resources remotely
Posted by Dishara Wijewardana <dd...@gmail.com>.
Hi Ian,
Thank you very much for this detailed steps. This was what I was looking to
gather from docs.
In step1, on services, there is no CassandraResourceProvider. I searched
for the name and there is no such. But in bundles I have it in active
state. I tried refreshing it again too. But still I cannot see the service.
In my provider class @Service annotation is defined
as @Service(ResourceProvider.class). Instead do I need to make it
as @Service(CassandraResourceProvider.class) ? How does the services
generated from bundles ?.
(I also verified this by uninstalling and then installing the cassandra
bundle and check whether service count decreases/increases)

Re: Read Sling resources remotely
Posted by Dishara Wijewardana <dd...@gmail.com>.
Hi Ian,
I added and commited a new load test class which adds bulk data to
cassandra. Can find all info how to configure it and run to add bulk data
in under a defined parent as you mentioned. But still I am blocking on the
issue I raised on using HTTP call to such added data.

There's no code in trunk at that line, you'll need to debug the
version of the code that you are using to find out what's happening.
In general, as your ResourceProvider interacts heavily with the Sling
core code, you will need to get used to debugging some of the Sling
code.
It's quite possible that we still have some bugs in there as we
haven't been using lots of different ResourceProviders so far, or it
might be your provider that's still missing some features - only
debugging will tell you what's happening.

Hi all,
I have created the JIRA [1] and attached the Apache Bench Mark results as
requested. All the reports and graphs attached to JIRA. I did it in 2
modes.
- All tests based on single server startup.
- Each test based on a fresh server startup.
[1] - https://issues.apache.org/jira/browse/SLING-3026

Would be good IMO to collect these stats in a jira issue, so that we
can keep track of the evolution.

Re: Read Sling resources remotely

Hi DIshara,
Excelent news.
Before you start on the next phase I would like to see some stats,
even if they are only rudimentary.
Can you build a test profile that adds
1K,10K,100K,1M items to Cassandra, each under 1 parent collection.
eg
/content/cassandra/1K/0 to /content/cassandra/1K/999
/content/cassandra/10K/0 to /content/cassandra/10K/9999
/content/cassandra/100K/0 to /content/cassandra/100K/99999
/content/cassandra/1M/0 to /content/cassandra/1M/999999
Then report on the http request time to retrieve 1 of those items from
each of those collections for he first request and for subsequent
requests. Use ApacheBenchmark for the timings. (eg ab -n1
http://localhost:8080/content/cassandra/1M/393452.json)
IIRC Cassandra will take writes at about 4K/s which so it should take
about 10 minutes to populate with 1M items. (my figures are probably
very old).
The reason for doing this is to get an rough idea of how this scales
and to provide a base line to see the impact of adding ACLs.
Thanks, great work!
Best Regards
Ian

Re: Read Sling resources remotely
Posted by Dishara Wijewardana <dd...@gmail.com>.
Hi Ian,
I followed the steps you aforementioned and it worked fine ! (I had to fix
couple of bugs I had in the code). This is Wonderful. It gives me the
asking resource if it is there. Unless says resource not exists. I tested
it having Cassandra running in back ground. I will start a new thread to
discuss on how to proceed with the rest of the impl.
Thank you very much :-).

Re: Read Sling resources remotely
Posted by Ian Boston <ie...@tfd.co.uk>.
Hi Dishara,
The ResourceResolverFactory bundle should not be using any bundle
implementing a ResourceProvider, as that would imply a circular
dependency.
It looks like your service is starting correctly as its listed as
service ID 257, component ID 103.
Looking at the code, I dont think you have defined where the
CassandraResourceProvider is "mounted", you need to set the
provider.roots property.
ie
@Component(immediate=true, metatype=true)
@Service(ResourceProvider.class)
@Properties({
@Property(name="provider.roots", value={ "/content/cassandra"})
})
public class CassandraResourceProvider implements ResourceProvider {
This tells the ResourceResolver where in the resource tree the
CassandraResourceProvider should be registered. IIRC its required for
registration. If you look at the logs carefully you might find the
ResourceResolver reporting a problem with registration.

includes ResourceResolverFactory class ?

Re: Read Sling resources remotely
Posted by Ian Boston <ie...@tfd.co.uk>.
Hi Dishara,
The Resource is not being found.
Things to check.
1. Check that the CassandraResourceProvider is registered with the
ResourceResolver at the correct path.
Got to
http://localhost:8080/system/console/services (login admin:admin)
Locate the CassandraResourceProvider and take a note of the service ID
(first column).
Locate the service for org.apache.sling.api.resource.ResourceResolverFactory
Click on the bundle link in the left hand column, in my case
http://localhost:8080/system/console/bundles/146
Check that the the service ID for the CassandraResourceProvider is
used by this bundle.
2. Put some Log statements in the CassandraResourceProvider to prove
that the ResourceResolver is calling it.
3. Make certain that the Resource that the CassandrResourceProvider is
returning is properly formed. It has resource metadata with a
resourceType and path.
You can use http://localhost:8080/system/console/jcrresolver to check
how URLs are resolved, or use a curl command.

Hi Bertrand
You are quite right. My provider works standalone and wants to make sure
whether my provider picked up by the sling engine. Where should I specify
my provider when calling the HTTP endpoint. Or if I call to a correct
resource path, will it picked it up ?
I tried writing something similar to PlanetsResourceProviderTest and did a
HTTP GET call to the endpoint "
http://localhost:8080/content/cassandra/movies/foo" and when I remotely
debug the test, the http client of HTTPTestBase receives a 404 for that GET
call..
NOTE: /content/cassandra/movies/foo is an existing resource node in
cassandra and my provider capable of returning it in standalone mode.
This is the BE error log..

You don't need JAX-RS, Sling provides RESTful HTTP APIs out of the box.

Yeah can be a good starting point - setup a Sling instance with your
resource provider active and create, retrieve, update and delete
resources via Sling's HTTP API.
You can also probably test your ResourceProvider without a Sling
instance, either with unit tests or pax exam integration tests. If you
can demonstrate there that it works according to the ResourceProvider
semantics, integration tests can be minimal and just verify that your
provider hooks up in the right way when activated.

Re: Read Sling resources remotely
Posted by Dishara Wijewardana <dd...@gmail.com>.
Hi all,
Thanks for the links and references. I looked in to the integration tests
since eventually that is the place I should be adding the Cassandra
Provider.
I looked inside the Test classes and base tests. The integration tests
calls to HTTP REST endpoints. So there should be a place that I should be
writing something like JAX-RS using sling APIs . (ResourceProviders and
etc) ? Or am I missing something in understanding this?
Hi Ian,
Since my next step is to test this within sling runtime, what is the best
way to access my provider and read resources ? Apparently what I should be
writing is something similar to PlanetsResourceProviderTest.

Besides the POST servlets docs mentioned by Shashank, this has the basics:

Most of our integration tests under launchpad/integration-tests use
HTTP requests to test a Sling instance, that's probably what you want.
However, in the meantime we have a more modern test framework that's
demonstrated at testing/samples/integration-tests, you might want to
have a look as well. Radu has been using that in his validation module
(it-http module in org.apache.sling.validation-2.zip patch in
SLING-2803), I like how that makes integration tests local to a single
module or small group of modules, that's probably a good choice in
your case.

for thoughts and best practices about testing.

Hi Dishara,
Following link[1] documents usage of slingpostservlet to manipulate content. You can use httpcomponents [2 ] in java client to make http calls.

Hi,
Can we access sling resources from a java client ? Is there any sample/links to refer ?
This is just to test the Cassandra impl on Sling. Now the Cassandra bundle is installed in sling server. There is a documentation on editing the JCR content through SlingPostServlet. Can I call this servlet and test my resource provider ?
