Why is my WS expecting a XMLGregorianCalendar datatype?

[Steve Vittoria]

Hi everyone!

I wrote a method for one of my web services that has to two Date input parameters. From my client, when I try to access this method I get an error stating the following...

required: java.lang.Long,javax.xml.datatype.XMLGregorianCalendar,javax.xml.datatype.XMLGregorianCalendar
found: java.lang.Long,java.util.Date,java.util.Date

Here is my Interface...

import java.util.Date;
import java.util.List;

import javax.ejb.Remote;
import javax.jws.WebService;
import javax.jws.soap.SOAPBinding;
import javax.jws.soap.SOAPBinding.Style;
import javax.jws.soap.SOAPBinding.Use;

@Remote
@WebService( name = "VitalSignService" )
@SOAPBinding( style = Style.DOCUMENT, use = Use.LITERAL )
public interface VitalSignService {

	public List<LabListDTO> getLabListDate( Long patientId, Date startDate, Date endDate );

}

Here is my class...

import java.util.ArrayList;
import java.util.Date;
import java.util.List;

import javax.ejb.EJB;
import javax.ejb.Stateless;
import javax.jws.WebService;

import org.jboss.wsf.spi.annotation.WebContext;

@Stateless
@WebContext( contextRoot = "/cis-ws", urlPattern = "/vitalSign" )
@WebService( endpointInterface = "ca.cis.vitalSign.VitalSignService" )
public class VitalSignServiceBean implements VitalSignService {

	@EJB
	LabListQuery labListQuery;

	public List<LabListDTO> getLabListDate( Long patientId, Date startDate, Date endDate ) {
		log.info("Patient ID: " + patientId);
		log.info("Start Date: " + startDate);
		log.info("Start Date: " + endDate);

		List<LabListDTO> labDto = new ArrayList<LabListDTO>();

		List<LabList> labs = labListQuery.getLabListDate( patientId, startDate, endDate );

		for( LabList lab : labs ) {
			labDto.add( createLabListDTO( lab ) );
		}

		return labDto;
	}

	private LabListDTO createLabListDTO( LabList labList ) {
		LabListDTO dto = new LabListDTO();

		dto.setSid( labList.getSid() );
		dto.setPid( labList.getPid() );
		dto.setEncounterID( labList.getEncounterID() );
		dto.setCollectedDate( labList.getCollecteddate() );
		dto.setResultDate( labList.getResultdate() );
		dto.setGenLabType( labList.getGenLabType() );
		dto.setState( labList.getState() );
		dto.setFillerNumber( labList.getFillernumber() );
		dto.setRangeReference( labList.getRangereference() );
		dto.setResultUnit( labList.getResultunit() );
		dto.setResult( labList.getResult() );
		dto.setServTypeRootAcro( labList.getServTypeRootAcro() );
		dto.setServTypeChildAcro( labList.getServTypeChildAcro() );
		dto.setServTypeChildLongDesc( labList.getServTypeChildLongDesc() );
		dto.setRangeIndicator( labList.getRangeindicator() );
		dto.setSortChildSeq( labList.getSortChildSeq() );

		return dto;
	}

}

Why is it expecting/wanting a javax.xml.datatype.XMLGregorianCalendar instead of a java.util.Date?
