[jbossws-users] [JBossWS] - ws can't map ArrayList to xsd:boolean

[mjea]

I have an EJB with the following method exposed as a web service:

public Collection getStatus(Ear data) throws OspMethodException, RemoteException;

I generated the wsdl using wstools. I have the following response generated:


  | ...
  | <message name="EarAccessService_getStatusResponse">
  | <part name="result" type="ns1:Collection"/>
  | </message>
  | ...
  | <operation name="getStatus" parameterOrder="Ear_1">
  | <input message="tns:EarAccessService_getStatus"/>
  | <output message="tns:EarAccessService_getStatusResponse"/>
  | <fault message="tns:OspMethodException" name="OspMethodException"/>
  | </operation>
  | ...
  | 

Now when I trigger the web service, the EJB method is correctly executed but the soap response creation fails with this error:

  | 10:00:33 ERROR .71-8080-1 [server.StandardEndpointServlet] Error processing web service request
  | javax.xml.rpc.JAXRPCException: org.jboss.xb.binding.JBossXBValueFormatException: Java value for XSD boolean type expected to be an instance of java.lang.Boolean or java.lang.Number. But the value is of type java.util.ArrayList

  | 	at org.jboss.ws.server.ServiceEndpointManager.sendResponse(ServiceEndpointManager.java:409)

It seems it tries to map my ArrayList (a Collection of Strings to return) to a boolean. How is that possible? Is there something I missed?
