The JaxrsServiceRuntime is rgeistered as a service, so far so good. But I
dont's see a osgi.jaxrs.endpoint  service property. 

@jbonofre do you have an idea what is missing within the karaf context?

Re: REST - Declarative Services

[Tim Ward]

Hi,

So there have been a number of suggestions on this thread which are 
unnecessary, and will confuse matters.

There is no need to provide a JAX-RS Application to use the JAX-RS whiteboard. 
The whiteboard always has a default application which is, unsurprisingly, what 
is used by default.
The “osgi.jaxrs.endpoint” property is a service property of the 
JaxrsServiceRuntime service. You can use it to work out what URI the JAX-RS 
whiteboard is available on. It does absolutely nothing when used as a property 
on your resource
The JAX_RS_APPLICATION_SELECT filter is not needed if you just want to use the 
default application to host your resource.

If you trim out the extra bits that have been added you should be back to a 
simple JAX-RS resource service that has the property 
“osgi.jaxrs.resource=true”. If you update to bnd 4.0 (the maven bundle plugin 
release was at the end of last week), then you can use the @JaxrsResource 
annotation to do this, otherwise you will need to keep using the String 
property name.

Verifying that the Aries JAX-RS whiteboard is working should be pretty simple. 
Once you have the bundle installed and running it will use the Http Whiteboard 
to register a Servlet. Once this is activated the whiteboard will register a 
JaxrsServiceRuntime service. If you look at the osgi.jaxrs.endpoint property of 
the JaxrsServiceRuntime service it will give you one or more URIs that you can 
use to reach the whiteboard. If you use a browser to connect to this URI you 
should get a welcome page.

If you don’t see a JaxrsServiceRuntime service then this indicates that the 
whiteboard servlet it uses hasn’t been picked up. This would be a problem with 
the Karaf web container.
If the URI presented as a service property of the JaxrsServiceRuntime service 
does not give you a welcome page then it indicates that Karaf is doing some 
level of context root setting. You will need to query the Karaf Http Whiteboard 
to work out what it might have done

Once you’ve validated that part it should be a case of installing/starting the 
bundle containing your resource, and navigating to it using the URI from 
before, plus the path of your resource method.

I hope this helps,

Best Regards,

Tim

Re: REST - Declarative Services

[Nicolas Brasey]

Hi,

Are you sure you are not missing the "cxf" prefix in the URL to access your
endpoint? By default, cxf deploys your endpoint with the
CXFNonSpringServlet, which listens on the cxf context path, so your
endpoint should be available here:

http://localhost:8181/cxf/hello 

my 2 cents...

Nicolas

Re: REST - Declarative Services

[Jean-Baptiste Onofré]

Hi,

did you try to add a application with your context.

Something like:

@Component(
service = Application.class,
property= {
"osgi.jaxrs.name=RestApp",
JAX_RS_APPLICATION_BASE + "=/rest", 
"authentication.with=keycloak"
}
)
public class RestApiApp extends Application{

@Override
  public Set getSingletons() {
  return Collections.singleton(this);
  }
}

The resource can refer this application:

@Component(
service = Api.class,
property = {
"osgi.jaxrs.name=RestApi",
"osgi.jaxrs.resource=true",

"osgi.jaxrs.application.select=(osgi.jaxrs.name=RestApp)"
}
)
@Path("/object")
public final class Api {
public static final Response EMPTY_RESPONSE =
Response.noContent().type(MediaType.TEXT_HTML_TYPE).build();
@GET
@Path("/getObject")
@Produces(MediaType.APPLICATION_JSON)
public String getObject() {
//return some json
}
}

JB

Hi Francois,

I treid that too. See this excerpt:

 component.id = 4
 component.name = de.rest.test.ExampleRest

 service.bundleid = 102
 service.id = 139
 service.scope = bundle

But when calling http://localhost:8181/hello, I get a 404 not found error.


Thansk for your input :)

May be you are missing the JAX_RS_SERVICE_ENDPOINT, there is a

Re: REST - Declarative Services

[atouat]

Hi @all,

Wow! Very active community here in the forum. I appreciate this, thanks.

@jbonofre In a current project at work, we already have rest services
running in karaf by using cxf and blueprint.
I also tried out @cschneider's propositon wiht cxf-dosgi and I got that
running too.

I just wanted to try out publishing rest services via whiteboard, and since
aries jax rs whiteboard is the reference implementation I took that.

About your example. My code looks like this:

/import org.osgi.service.component.annotations.Activate;
import org.osgi.service.component.annotations.Component;
import org.osgi.service.jaxrs.whiteboard.JaxrsWhiteboardConstants;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;


@Component(
immediate = true,
property = {
JaxrsWhiteboardConstants.JAX_RS_APPLICATION_SELECT +
"=(osgi.jaxrs.name=.default)",
JaxrsWhiteboardConstants.JAX_RS_RESOURCE + "=true"
},
service = ExampleRest.class
)
public class ExampleRest {

@Activate
public void onActivate(){
System.out.println("ExampleRest activating!");
}

@GET
@Path("/{name}")
public String sayHello(@PathParam("name") String name) {
return "Hello " + name;
}

}/

The generated service.component.xml under OSGI-INF looks like this:

/
http://www.osgi.org/xmlns/scr/v1.3.0;
name="de.rest.test.ExampleRest" immediate="true" activate="onActivate">
  
  

  
  
  
/


And the generated Manifest like this:

/Manifest-Version: 1.0
Bnd-LastModified: 1536171585428
Build-Jdk: 1.8.0_171
Built-By: adnan
Bundle-Description: de.rest.test.whiteboard.ds OSGi bundle project.
Bundle-ManifestVersion: 2
Bundle-Name: de.rest.test.whiteboard.ds Bundle
Bundle-SymbolicName: de.rest.test.whiteboard.ds
Bundle-Version: 1.0.0.SNAPSHOT
Created-By: Apache Maven Bundle Plugin
Export-Package: de.rest.test;version="1.0.0.SNAPSHOT";uses:="javax.ws.
 rs"
Import-Package: javax.ws.rs;version="[2.1,3)"
Provide-Capability: osgi.service;objectClass:List="de.rest.tes
 t.ExampleRest"
Require-Capability: osgi.extender;filter:="(&(osgi.extender=osgi.compo
 nent)(version>=1.3.0)(!(version>=2.0.0)))",osgi.ee;filter:="(&(osgi.e
 e=JavaSE)(version=1.8))"
Service-Component: OSGI-INF/de.rest.test.ExampleRest.xml
Tool: Bnd-3.5.0.201709291849/

I also already had a look at the osgienroute example @Tim-Ward-2 mentioned.
I created the rest bundle based on the osgi enroute maven archetype. The
code looks very similar (The following is the code generated by the enroute
archetype):

/import javax.ws.rs.GET;
import javax.ws.rs.Path;

import org.osgi.service.component.annotations.Component;
import org.osgi.service.jaxrs.whiteboard.propertytypes.JaxrsResource;

@Component(service=RestComponentImpl.class)
@JaxrsResource
public class RestComponentImpl {

//TODO add an implementation

@Path("rest")
@GET
public String toUpper() {
return "Hello World!";
}
}
/

I couldnt get a well generetaed manifest by the bnd-tool, so I used the
maven-bundle.-plugin and the generetd service.component.xml and the genrated
Manifest look similar too.


After installing the feature as mentioned in my previous post and deploying
the bundle with you corde examples @jbonofre 
 (bundle symbolic name is de.rest.test.whiteboard.ds Bundle)  and also the
enroute exmaple bunlde (bundly symbolic name is rest-enroute), I have the
following in karaf:

Got it ;)

AFAIR, Christian started a PoC about a Karaf resolver. I will resume 
what he started.

The project is deliberately not opinionated about server platforms,

resolves and assembles the bundles you need based on your

Other than the Aries JAX-RS whiteboard integration tests (which aren’t a gentle 
introduction!) enRoute has the only working examples I’m currently aware of.

Re: REST - Declarative Services

[Jean-Baptiste Onofré]

OK, it's what I knew ;)

So, basically, you answer helped the user generally speaking but I guess 
it's not exactly what the user expects.


Karaf has exactly the same target for the runtime space. Karaf Boot is 
more on the same space as enRoute.


I would be more than happy to help to support Karaf in enRoute, but it 
seems that Karaf doesn't have a lot of supporters "at" enRoute. I got 
comment from some enRoute guys saying that Karaf doesn't make sense and 
other blabla. That's why I didn't find the motivation to help ;)


Anyway, back on the user request, @Adnan I will add an example using 
Aries JAXRS in Karaf.


Thanks,
Regards

Re: REST - Declarative Services

[Tim Ward]

OSGi enRoute is a project aimed at getting users with little/no OSGi experience 
familiar with OSGi specifications and best practices. It produces bundles and 
repository indexes, but it is not itself a runtime. 

The project is deliberately not opinionated about server platforms, and so it 
doesn’t use Karaf or any other platform. Instead it resolves and assembles the 
bundles you need based on your application requirements (using the standard 
OSGi resolver model and your build dependencies). The output is a standalone 
executable JAR so that the code can be easily run and debugged.

If someone wanted to describe how to export a KAR/feature, or to add a Karaf

Re: REST - Declarative Services

[Jean-Baptiste Onofré]

Hi,

My example works for the http whiteboard, but not Aries JAXRS 
whiteboard. For JAXRS, I provided example based on CXF.


If CXF is not convenient for you, I can add a Aries JAXRS Whiteboard 
example, no problem.


If your case, 404 means that the "listener servlet" has not been 
deployed or not on the alias you expect.


Did you check what you have with http:list command ?

It's debatable to say that the JAX-RS whiteboard spec is more portable 
than using RSA.   Portability can mean multiple things...e.g. across 
impls (e.g. CXF or Jersey), or service contracts across transports (http 
vs. mqtt).   Further, RSA does have things that JAXRS currently 
lacks...e.g. proxys, mgmt agent, topology mgr, discovery/edef.


But I don't wish to debate.   I'll just point to an example running on 
Karaf that uses Jersey, CXF, JAX-RS, OSGi R7 RSA:

Hi Guenther,

Another option would be ECF Remote Services [1]. It's a full 
implementation of the OSGi Remote Services and Remote Service Admin 
(R7/latest) specifications [2].   These specifications standardize 
the remoting of OSGi services (meta-data and dynamics), so it works 
seemlessly with DS and other frameworks that use the OSGi service 
registry.


ECF has a provider architecture so allows the use of a variety of 
distribution providers [3], including CXF [4].


We have features defined for Karaf [5] and we also now have support 
for bndtools-based development [6] (workspace and project templates).


Caveat:   ECF is in the middle of 'release season' for the Eclipse 
simultaneous release (late June), so the transition to ECF 3.14.0 is 
not yet complete.  For example, the Karaf features don't yet point to 
3.14.0 at maven central only because we have to wait for the SR  
process before deployment of the release to maven central.   However, 
I'm happy to provide needed support via [7].

Take a look at these two:

 https://github.com/steinarb/post-body-capture
   A super-simple REST service/debug tool that just writes the POSTed
   body to a file, and the file name to the injected OSGi log service (I
   used it to see what sonarcloud was sending to its webhooks)

 https://github.com/steinarb/sonar-collector
  A REST service intended to be used as a postbuild SonarCloud/SonarQube
  webhook.  The service will store key numbers from the build in a
  PostgreSQL database.
  Nifty things here are using liquibase to initialize the PostgreSQL
  database and injecting config in the @Activate method, allowing the
  JDBC connection info to be configured from the karaf console.

Build and install information can be found in the README files.

Re: REST - Declarative Services

BTW: these should be the features I installed in karaf ...

Another option is to use CXF-DOSGi. You can find an example below. It 
is similar to Aries JAX-RS so a later switch should be easy.

Hello All,

I’ve been developing services using Declarative Services for
dependency injection and it was a breeze so far. Now I want to
expose some of the functionality via a REST API and I’m stuck. So
far I’ve deployed my bundles through bundle:install -s man: …. all
very easy. But what should be simple, exposing this through REST
is becoming difficult. There are tips out there suggesting to use
Blueprint, which I don’t want, others seem to suggest that I need
to create a “feature” package.

Then there’s also the requirements to “feature” install cxf.
That’s OK btw, I only have to do that once. But is there really no
simple way to create a simple REST service using merely DS?

Guenther

Aries JAX-RS should work. It is not yet released though. So currently there
is only a snapshot. A release should follow soon.

Re: REST - Declarative Services

Hi Guenther,

You can use CXF registering the CXF JAXRS server using DS.

Another option could be to use Aries JAXRS with the whiteboard pattern.

We are preparing samples about that:

https://github.com/jbonofre/karaf/tree/DEV_GUIDE/examples/karaf-rest-example

I will add an example with Aries JAXRS and DS.

With Aries JAXRS, you can simply do:

@Component(
property = {
JaxrsWhiteboardConstants.JAX_RS_APPLICATION_SELECT +
"=(osgi.jaxrs.name=.default)",
JaxrsWhiteboardConstants.JAX_RS_RESOURCE + "=true"
},
service = ExampleRest.class
)
public class ExampleRest {

@GET
@Path("/{name}")
public String sayHello(@PathParam("name") String name) {
if (_log.isDebugEnabled()) {
_log.debug("URI: " + _uriInfo.getAbsolutePath());
}

return "Hello " + name;
}

@Context
UriInfo _uriInfo;

private static final Logger _log = LoggerFactory.getLogger(
ExampleAddon.class);

}

Regards
JB
