Summary: Improve loading of annotated classes for
AnnotationServiceFactory.createAnnotationService(String)
Key: OLINGO-177
URL: https://issues.apache.org/jira/browse/OLINGO-177
Project: Olingo
Issue Type: Improvement
Components: odata2-annotation
Affects Versions: V2 1.1.0
Reporter: Michael Bolz
In some environments (e.g. OSGi, some Application Servers) the
{{AnnotationServiceFactory.createAnnotationService(String)}} fails to load
the annotated classes based on package reference.
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.
In most environments a deployed war which contains the model package in a
Tomcat or Jetty works combination the
AnnotationServiceFactory.createAnnotationService(String).
