[DOSGi] Reworking the system tests
Hi all, One of the things to-do for the DOSGi refactoring work that's currently happening on trunk is to re-enable the system tests. Now both Sergey and I have been fighting with the spring-osgi based testing system that's there before and I can tell you it's generally no fun at all. The biggest problem that I've encountered with it is the interference of the test framework with the CXF-DOSGi code as they both use Spring-DM but sometimes have conflicting requirements. So I'd like to spend a little bit of time refactoring the system tests to use Pax-Exam. I haven't used it in anger yet but I've heard good things about it and it should not suffer from the interference problem. Thoughts anyone? David
Re: [DOSGi] Reworking the system tests
David, One thing to note about pax-exam is that its doesn't AFAIK have a feature analogous to the spring-osgi-test support for accessing and adding to the manifest for the on-the-fly bundle. Now I don't know whether we could possibly live without this manifest-mangling as currently done by the dOSGi systests, specifically setting the DynamicImport-Package header to "*". If we can live without this setting, no worries. If not, its something to consider about adopting pax-exam.

Re: [DOSGi] Reworking the system tests
Thanks for the heads up Eoghan. I understood that the recent tiny bundles integration could take care of this. Have a look at the bottom example in http://wiki.ops4j.org/display/paxexam/ExamAndTinybundles. Do you think that will do it?

Re: [DOSGi] Reworking the system tests
Yep, now that you mention it, tiny bundles were what Toni Menzel of the PAX team suggested using when we tripped over a similar issue with the SMX integration tests during the Karaf switch-over.

Re: JAXB and JAX-RS under CXF
Thanks Sergey, just one more question. I converted a plain (non-OSGi) JAX-RS project to DOSGi-based CXF. Now, for some of my JAXB annotated classes I get the error message: com.sun.istack.internal.SAXException2: unable to marshal type "a.b.c.X" as an element because it is missing an @XmlRootElement annotation I use Pax Exam to set up a test case that marshalls the object to a byte[] and unmarshalls it afterwards from it. Do you know that error? Why is CXF behaving different than "plain" JAXB? Is it using a different JAXB implementation at all? And if yes, is it possible to switch to the implementation included in the JVM?

Yes, they do. I use Pax Exam to set up a test case that marshalls the object to a byte[] and unmarshalls it afterwards from it. Do you know that error? S.B : yes, usually it is to do with @XmlRootElement being not present or, in OSGI case, being 'lost' at runtime, due to a missing import package value...You can condigure DOSGI RI to not require @XmlRootElement for JAXRS services... I checked the packaged bundle. It definitely has the JAXB annotation packages imported (which is no wonder as I'm using maven-bundle-plugin with bnd to generate the Manifest). S.B : for some reasons there're still invisible to the JAXB runtime. One of users reported a similar issue the other day, JAXB classes have been moved to a bundle separate from the application one. I don't recall what the fix was, it is just a visibility issue which can be solved at the OSGI level. Please attach a sample bundle if it won't work... How can I configure it for use without annotations? S.B : You'll need to register a custom JAXBElementProvider as a MessageBodyReader and MessageBodyWriter OSGI service and set a property on it (marshalAsJaxbElement). One will be able to do the same from Spring DM context once we fix the issue of discovering well-known spring beans... Why is CXF behaving different than "plain" JAXB? S.B : what exactly is different ? Just that plain works, and OSGi-based fails because of the errors mentioned above. But I guess that's "misconfiguration". S.B : yes, it's an OSGI configuration issue. DOSGI can't help on its own...At the last resort try DynamicImport... cheers, Sergey Is it using a different JAXB implementation at all?

I just tried and it works just fine. In fact, documentation was either misleading or I misread. The documentation says "This property has a limited value for JAXRS services as JAXB is supported by default, the only supported value is 'aegis' and it is a shortcut for registering an Aegis provider [...]" which is a little hard to understand.

S.B : it kind of does not makse sense, now that I read it again. (CXF) JAXRS do not use (CXF)databindings as often as they use 'providers', technically both terms are probably identical, but I wanted to not require users to set this property given that they will probably want to register say a DataBindingProvider provider delegating to CXF Aegis as OSGI service, with some custom configuration, etc...That said, for simple cases, letting users just to do "org.apache.cxf.rs.databinding=atom" would also make sense... JAXB will be supported with or without "org.apache.cxf.rs.databinding=jaxb" but I'll look into simplifying the documentation and enhancing a bit the way this org.apache.cxf.rs.databinding property is handled... thanks, Sergey Thanks for the clarification and the impressively fast response!

Are you seeing any issues ? I'm thinking may be I've just done another piece of the documentation which is confusing ? One thing I'm saying there is that
Re: JAXB and JAX-RS under CXF
Sergey, I'm unsure if that is something that can be fixed at DOSGi level. I just made a demo project and attached it to this mail. I will also send it to the Apache Felix guys who hopefully can inspect the issue (if they care) :D because felix's the framework that doesn't work.
