ClassCastException when trying to return an array of beans from a web service.

[Oggy Doytchinov <Do...@adr.org>]

Hi,

I am trying to create a web service that returns an array or java been objects. I have written a class with a method that returns the array. My java beans are only using simple types strings and integers. But whenever I tried to call them from the TestClient class the code is failing with ClassCastException. Here is the output from the screen:

Exception in thread "main" AxisFault

        at documents.TestClient.main(TestClient.java:17)

Here is the code from my TestClient class that calls the service:

    IDocuments service = new IDocumentsServiceLocator().getdocuments();
    DocTypeView[] resp = service.getDocumentTypes(userId, password);

The client code was generated by running java2wsdl and wsdl2java against the IDocuments interface:

public interface IDocuments  {
  public DocTypeView[] getDocumentTypes(String user, String password) throws Exception;
}

Here is the definition of the DocTypeView bean:

public class DocTypeView implements Serializable {
    private String code;
    private String description;
    private String parentCode;
    private String parentSubsys;
    private String subsys;

    public DocTypeView() {
    }

... getters and setters for all of the above attributes 
}

I have made a test writing a method that returns a simple string and it worked, but the moment I try to use the array or even to return a single bean I am getting an error.
Do I need to write my own serializers and deserializers for the bean? What am I doing wrong?

I would greatly appreciate any help to this problem,
