[Converter] Provide-Capability missing?
Hi!
I am very interested in the Converter. As David B. requested on the bndtools list, I am writing here for questions/comments. There will surely be more to come, but here is the first.
I tried replacing the enRoute version of DTOs with the Felix version, but the system does not resolve. I noticed that there is no Provide-Capability for “osgi.enroute.dto.api".
Here is the Manifest I get when I build the bundle locally:
> Bundle-License: http://www.apache.org/licenses/LICENSE-2.0.txt
> Bundle-ManifestVersion: 2
> Bundle-Name: Apache Felix Converter Service
> Bundle-SymbolicName: org.apache.felix.converter

Is this a small oversight? Or am I misunderstanding something? I thought that this is supposed to implement DTOs, so shouldn’t it provide that capability?
Thanks!

Hi David B.,
Thank you, you helped me find the problem. :-)
Turns out I was mixing this up with the “old” enRoute implementation. All good now.
Cheers,

Hi David,
Thanks for pinging here :)
The converter can convert to/from DTOs (BTW this part is not very well
tested yet) but it does not implement the enroute DTO API. Not sure why it
should?
Basically the way you'd use the converter with DTOs would be for example to
convert a key/value map into a DTO.
So that would look like this:
MyDTO dto = converter.convert(myMap).to(MyDTO.class);
or the other way around:
Map m = converter.convert(dto).to(Map.class);
You can use any DTO from anywhere, including ones from Enroute...
What is it that you think it should provide in addition?
Thanks,
David
