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:
/<?xml version="1.0" encoding="UTF-8"?>
<scr:component xmlns:scr="http://www.osgi.org/xmlns/scr/v1.3.0";
name="de.rest.test.ExampleRest" immediate="true" activate="onActivate">
<implementation class="de.rest.test.ExampleRest"/>
<service>
<provide interface="de.rest.test.ExampleRest"/>
</service>
<property name="osgi.jaxrs.application.select" type="String"
value="(osgi.jaxrs.name=.default)"/>
<property name="osgi.jaxrs.resource" type="String" value="true"/>
</scr:component>/
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.

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:
/

karaf@root()> /
With the command karaf@root()> service:list , I get (excerpt) :
/karaf@root()> service:list
[de.rest.test.ExampleRest]
--------------------------
component.id = 2
component.name = de.rest.test.ExampleRest
osgi.jaxrs.application.select = (osgi.jaxrs.name=.default)
osgi.jaxrs.resource = true
service.bundleid = 102
service.id = 123
service.scope = bundle
Provided by :
de.rest.test.whiteboard.ds Bundle (102)
[val.rest.enroute.RestComponentImpl]
------------------------------------
component.id = 3
component.name = val.rest.enroute.RestComponentImpl
service.bundleid = 103
service.id = 124
service.scope = bundle
Provided by :
rest-enroute (103)/
With the command karaf@root()> http:list , I get :
/karaf@root()> http:list
ID │ Servlet │ Servlet-Name │ State │ Alias │ Url
───┼─────────┼──────────────┼───────┼───────┼────
karaf@root()> /
Yes, nothing. So no servlet or something in that regard is registered. It
can not work, right?
When I install the feature cxf-jaxrs I get this:
/karaf@root(feature)> http:list
ID │ Servlet │ Servlet-Name │ State │ Alias
│ Url
────┼─────────────────────┼────────────────────────────┼─────────────┼───────┼─────────
114 │ CXFNonSpringServlet │ cxf-osgi-transport-servlet │ Deployed │ /cxf
│ [/cxf/*]
karaf@root(feature)/
I assume I am missing something obvious and substantial. Can someone point
me to what I am missing?
Thanks in advance!
Greetings,
Adnan
