Summary: Add sample project that demonstrates AEM integration for Caravan JAX-RS
Key: WCARAV-6
URL: https://wcm-io.atlassian.net/browse/WCARAV-6
Project: wcm.io Caravan
Issue Type: Improvement
Components: JAX-RS
Reporter: Paul Bjorkstrand
Currently, I see no usage instructions nor sample project that fully demonstrates usage of Caravan JAX-RS inside AEM. In trying to set it up, I have encountered numerous pitfalls (missing bundles, package conflicts, etc) that seem like they would warrant entries into the documentation.

Paul Bjorkstrand commented on WCARAV-6:
Addendum: It looks like it is registering the servlet and all of the things it need so do. The registered servlet shows on the http whiteboard, but the {{service(…)}} method never gets called. I'm not sure right now if it is a version problem or what, but something just isn't going well in AEM 6.3. I did try to get the [JAX-RS OSGi Connector|https://github.com/hstaudacher/osgi-jax-rs-connector] working, and succeeded, to some extent, but I would much prefer to get this working.

i will try to setup a small sample project.
what is your use usecase? # consuming REST services from outside in AEM # publishing REST services in AEM # using the caravan pipeline mechanics
Paul Bjorkstrand (JIRA)
Paul Bjorkstrand commented on WCARAV-6:
The use case is publishing REST services from AEM. Basically, I am trying to get the following to work: {code:java} package project.jaxrs;
import javax.ws.rs.GET; import javax.ws.rs.Path; import javax.ws.rs.PathParam; import javax.ws.rs.Produces; import javax.ws.rs.core.MediaType; import org.osgi.service.component.annotations.Component; import io.wcm.caravan.jaxrs.publisher.JaxRsComponent;
@Component @Path("/test") @Produces(MediaType.APPLICATION_JSON) public class TestService implements JaxRsComponent {
@GET
public String get() {
return "GET";
}
@GET
@Path("{id}")
public String getById(@PathParam("id") String id) {
return "GET/" + id;
}
} {code}
The {{Caravan-JaxRs-ApplicationPath}} bundle instruction is set to {code:xml} <Caravan-JaxRs-ApplicationPath>/services</Caravan-JaxRs-ApplicationPath> {code}
What I am currently battling is that in AEM 6.3 SP1, the {{ServletContainerBridge}}'s {[service(..)}} method is not even being called (confirmed to be the problem by debugging). I have verified that the service & servlet are registered (both via the services listing and the Http Whiteboard).

More notes:
I have tried to pull apart the caravan functionality, and move only a barebones set of modified classes from caravan into my bundle It is almost working, but I get an exception on the call of {{ServletContainerBridge.init(ServletConfig)}}. I would be interested in knowing what the caravan does to not encounter this issue (if it does anything)

i've added a simple example application here: https://github.com/wcm-io-caravan/caravan-jaxrs/tree/develop/examples/aem-caravan-jaxrs-sample
from the stacktrace – maybe you've missed to deploy the {{hibernate-validator}} bundle to you instances? see list of deployed dependencies in my example.
Paul Bjorkstrand (JIRA)
Paul Bjorkstrand commented on WCARAV-6:
I dug down, and think I found the issue, but have no proposal for a resolution, yet. I'll try to explain the issue as best as I can.
In the bundle {{jersey-bean-validation-2.20.jar}} there is a java service listed in {{META-INF/services}}. The service interface is {{org.glassfish.jersey.internal.spi.ForcedAutoDiscoverable}}, which exposes the {{org.glassfish.jersey.server.validation.internal.ValidationAutoDiscoverable}} service implementation.
This service locator is preventing glassfish from finding/creating a Validator implementation, which causes the thrown exception when calling {{ServletContainer.init(ServletConfig)}} (that is largely a guess, I don't know Glassfish/javax.validation that well).
When you remove that service locator from that jar, then rewrap it all together, it starts working just fine. After some heavy debugging, I found that the exact spot it was throwing, and made an educated guess as to the cause. To help guide my testing, I compared what was in the service registry in http://central.maven.org/maven2/com/eclipsesource/jaxrs/jersey-min/2.22.2/ to what was in the nested jars in http://central.maven.org/maven2/io/wcm/osgi/wrapper/io.wcm.osgi.wrapper.jersey/2.20-0000/ .
This was the first difference between the two, with respect to service locator. This explains why the JAX-RS OSGi Connector works, when using its dependencies, while Caravan does not, when using the listed dependencies (aka, the two different Jersey combined jars).
Paul Bjorkstrand (JIRA)
Paul Bjorkstrand commented on WCARAV-6:
Heh, we both posted within a minute of each other :-)
I tried to add the dependencies, and it was still not working, but maybe I missed something. I'll take a look at your sample and try it out. I would much prefer to use the already available bundles, rather than having to generate & house one in the project.
