Hi,
I noticed that Johnzon has OSGi headers, which is nice :-)
I am trying to setup Johnzon in a minimal OSGi container. I have a
bundle which performs a very simple JSON rendering:
try ( JsonGenerator g =
Json.createGenerator(resp.getOutputStream())) {
resp.setContentType("application/json");
g.writeStartObject()
.write("enabled", routerAdmin.isWlanEnabled() )
.writeEnd();
} catch (AuthException e) {
resp.setStatus(HttpServletResponse.SC_INTERNAL_SERVER_ERROR
);
}
I am deploying the following bundles to my container:
- Johnzon :: Core (0.9.4) - org.apache.johnzon:johnzon-core:0.9.4
- Apache Geronimo JSon Spec 1.0 (1.0.0.alpha-1) -
org.apache.geronimo.specs:geronimo-json_1.0_spec:1.0-alpha-1
The code fails with
javax.json.JsonException: org.apache.johnzon.core.JsonProviderImpl
not found
(full stack trace at the end ).
My question is - is this a supported scenario? Looking at the bundle
headers I don't see how the wiring could happen between these the JSON
API and Johnzon Core bundles, as they know nothing about each other.
(Please keep me in CC, I am not subscribed).
Thanks,
Robert
