Resolve java.util.List is an interface, and JAXB can't handle interfaces.

Removed

Working on a Web service, I caught this error while deploying:

Caused by: com.sun.xml.bind.v2.runtime.IllegalAnnotationsException: 1 counts of IllegalAnnotationExceptions
java.util.List is an interface, and JAXB can't handle interfaces.
this problem is related to the following location:
at java.util.List

The problem comes from my WebMethod where I am returning a List<List<Car>>.  JAXB don't know how to handle this. So I have found a Solution where I define a new bean conating the List:


Class Cars{
    private List<car> cars;
...

}

So my WebMethod will return List<Cars>. This new bean resolves the problem. Make Sure also that the attribute is private (or don't put it at all, by default it will be private) otherwise you can have an error :
Class has two properties of the same name. See this post.
