[kura-dev] DataService questions
|
Howdy,
I'm using version 2.0.1 of DataService and have a couple of questions:
1) I see that the DataService API has changed a little...e.g. deprecating org.eclipse.kura.data.DataServiceListener in favor
of org.eclipse.kura.data.listener.DataServiceListener (and the associated DataService.add/removeDataServiceListener). I had been using the looking at the discussion/example usage here [1] . I don't see any DataService example in the kura/examples area of source. Are there examples from Kura or elsewhere that use the 2.0.1 approach?
2) How does one configure the mqtt DataService implementation? For example, what is the default Mqtt broker URL that's used, and is it possible to configure the broker URL?
3) I'm using the developer workspace available here [2] on Windows (currently) and running a test bundle that references the DataService with the target platform set to /target-definition/kura-equinox_3.8.1.target. Launching directly from Eclipse results in a number of services not being satisfied...see below for output of 'ls' and 'comp' command from OSGi console.
Is this (launching from Eclipse with target platform on windows) possible (e.g. for testing, etc)? If so how is that done for use of the DataService specifically?
4) Is there some docs on the various Kura services (e.g. DbService, DataTransferService, CloudConnectionStatusService) etc along with info about the dependencies between them? Obviously I'm particularly interested in resolving the required dependencies for the org.eclipse.kura.core.data.DataServiceImpl component (22 in console output below).
5) I haven't been able to download/install the mToolkit, and it seems that the kura-equinox_3.8.1.target platform expects to use/startup the mToolkit (in the dev workspace anyway). Is there some way to work around this (e.g. removing bundles dependent upon the mToolkit lib)?
Thanksinadvance,
Scott
