The easiest way is using Annotations.
Did you use @JSON on class level too? Sounds like you missed that. Fore xample:
@JSON
public class Webdvcr extends _Webdvcr {
@JSON List<Webdvcr> getDvcrByUnitNum(String s) {};
}
The code would then look like:
private String getJsonExample() {
JSONAnnotationEncoder encoder = new JSONAnnotationEncoder();
List<Webdvcr> test = Webdvcr.getDvcrByUnitNum("502");
return encoder.encode(test);
}
Please let me know if that worked for you.
Cheers
Christian
