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

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.soap.SOAPContentElement.write(SOAPContentElement.java:986) | at org.jboss.ws.soap.SAAJElementWriter.writeElement(SAAJElementWriter.java:171) | at org.jboss.ws.soap.SAAJElementWriter.writeElement(SAAJElementWriter.java:184) | at org.jboss.ws.soap.SAAJElementWriter.writeElement(SAAJElementWriter.java:184) | at org.jboss.ws.soap.SAAJElementWriter.writeElement(SAAJElementWriter.java:184) | at org.jboss.ws.soap.SAAJElementWriter.printInternal(SAAJElementWriter.java:163) | at org.jboss.ws.soap.SAAJElementWriter.print(SAAJElementWriter.java:142) | at org.jboss.ws.soap.SOAPMessageImpl.writeTo(SOAPMessageImpl.java:266) | 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? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3998198#...
