-------------------------------------
Hi Petr,
again thanks for your feedback.
The mentioned issue with the
{{AnnotationServiceFactory.createAnnotationService(String)}} is based on a
limitation with Java.
Unfortunately it is not that easy to get all available classes within a java
package. To get these it is necessary to access the folder (i.e. the
corresponding folder to the java package) and read the filenames. And dependent
on the environment (e.g. _Application Server_, _OSGi_, _.._) their exists no
accessible folder. In this case currently the only solution is to use
{{AnnotationServiceFactory.createAnnotationService(Collection)}} and providing
the classes directly as you have done.
In my main environment I deploy a {{war}} which contains the model package in a
_Tomcat_ or _Jetty_. In this combination the
{{AnnotationServiceFactory.createAnnotationService(String)}} works.
And to your question to _create an annotation service factory for multiple
packages_. Currently this is not supported. But you could create an feature
request for this in JIRA (and then someone can contribute an implementation).
As workaround it is possible to use a parent package for different models. E.g.
{{org.olingo.sample.model.one}} and {{org.olingo.sample.model.two}} for models
and then for creation of the service {{org.olingo.sample.model}} as package.
But the limitation/issue from your mentioned issue will still be there.
Kind regards,
Michael
