How to set minOccurs="1" in wsdl for an input parameter to web service method.

[Kavita Mohite]

Hi,

I have a web service implemented with apache cxf and spring. I have one web method which takes String argument as the input parameter. When I check the wsdl for this web method I see that the occurrence indicator minOccurs is set to 0 for the String input parameter. Here I want to set both minOccurs and maxOccurs to 1 to indicate that the input parameter is mandatory and singleton. To do this I used the annotation @Xmlelement and set its property required=true for the string input parameter, but this is not getting reflected in the wsdl. Am I doing something wrong here ? How do I get this right ?

Here is the code :

// Following is interface for web service

@WebService
public interface TWebService {
	@WebMethod(operationName="getAssociatedProjects")
	@XmlElement(name="userId", required=true, nillable=false,type=String.class)
	public String getAssociatedProjects(@WebParam(name="userId") String userId);
}



//Following is the implementation of interface

@WebService(endpointInterface = "com.test.ws.TWebService", serviceName="TService", portName="TServicePort",  name="TServiceInterface" )
public class TWebServiceImpl implements TWebService{

	@XmlElement(name="userId", required=true, nillable=false,type=String.class)	
	public String getAssociatedProjects( String userId) {
            String test_string="test_string";
            .
            .
            .
            return test_string;		

	}
	
}

Thanks
