    Web services and parameters

      I've been on this one a while so any help would be kindly appreciated!!!!

      === QUESTION 1 ===
      How do I write the 2 lines of Java code below in CF to pass into a web service?
      String[] countriesCovered = null;
      Attribute[] attributes = null;
      === QUESTION 2 ===
      I've tried to solve this problem by consuming a simple web service. If there are any web services experts out there please show yourself, and show me how to get the code below to work!!!
      ws = CreateObject("webservice"," http://www.weather.gov/forecasts/xml/SOAP_server/ndfdXMLserver.php?wsdl");
      NDFDgenResponse = ws.NDFDgen(JavaCast('double',38.99),JavaCast('double',-77.99),JavaCast('string','time-ser ies'),
      DateFormat('2004-01-01','mm/dd/yyyy hh:ss'),DateFormat('2010-06-26','mm/dd/yyyy hh:ss'));
      <cfdump var="#NDFDgenResponse#">
      ANd here's the error:
      Web service operation "NDFDgen" with parameters {38.99,-77.99,
      time-series,01/01/2004 12:00,06/26/2010 12:00} could not be found.

      I'm certain that the problem here is how I'm passing in parameters.
      Weather it be a complex type or a date or whatever, I'm doing
      something wrong!

      Any ideas... anyone??!?!?!?

      === QUESTION 3 ===
      I'm having problems passing parameters into a complex web service (WS) which I need to consume.
      Here is the latest error:
      Unable to create web service argument class [Ljava.lang.String;.
      Error: java.lang.InstantiationException: [Ljava.lang.String;. Often
      this is because the web service defines an <i>abstract</icomplexType
      as an input to an operation. You must create an actual instance of
      this type in Java.
      :::Here's my code:::
      webservice = CreateObject("webservice","url?wsdl");

      countriesCovered.France = JavaCast("string","FR");

      result = webservice.doSearch(JavaCast("string","123456"),
      JavaCast("null",""), JavaCast("null",""), countriesCovered,
      I've tried so many options (it feels like I can see the top of the
      hill :)) but I just can't get doSearch method to work. FYI: I've had
      no problems getting strings returned from simple functions (where no
      input was required) but it's the complex functions which I can't get
      to work (like this doSearch method).

      Here's some snippets of the WSDL:
      :::Snippet 1:::

      <schema targetNamespace="soap.ws.web.raileurope.com">

      <import namespace=" http://schemas.xmlsoap.org/soap/encoding/"/>

      <complexType name="ArrayOf_xsd_string">


      <restriction base="soapenc:Array">

      <attribute ref="soapenc:arrayType" wsdl:arrayType="xsd:string[]"/>




      <complexType name="Attribute">


      <element name="name" nillable="true" type="xsd:string"/>

      <element name="value" nillable="true" type="xsd:string"/>



      <complexType name="ArrayOfAttribute">


      <restriction base="soapenc:Array">

      <attribute ref="soapenc:arrayType"




      :::: Snippet 2 :::
      <wsdl:message name="doSearchResponse">

      <wsdl:part name="doSearchReturn" type="impl:SearchResult"/>
      <wsdl:message name="doSearchRequest">

      <wsdl:part name="key" type="xsd:string"/>

      <wsdl:part name="locale" type="xsd:string"/>

      <wsdl:part name="style" type="xsd:string"/>

      <wsdl:part name="countriesCovered" type="impl:ArrayOf_xsd_string"/>

      <wsdl:part name="attributes" type="impl:ArrayOfAttribute"/>

      ::: Snippet 3 :::
      <wsdl:portType name="Test">

      <wsdl:operation name="doSearch" parameterOrder="key locale style
      countriesCovered attributes">

      <wsdl:input message="impl:doSearchRequest" name="doSearchRequest"/>

      <wsdl:output message="impl:doSearchResponse"

      ::: Snippet 4 :::
      <wsdl:binding name="TestWebServiceSoapBinding" type="impl:Test">

      <wsdlsoap:binding style="rpc" transport=" http://schemas.xmlsoap.

      <wsdl:operation name="doSearch">

      <wsdlsoap:operation soapAction=""/>

      <wsdl:input name="doSearchRequest">

      <wsdlsoap:body encodingStyle=" http://schemas.xmlsoap.
      org/soap/encoding/" namespace="soap.ws.web.raileurope.com"


      <wsdl:output name="doSearchResponse">

      <wsdlsoap:body encodingStyle=" http://schemas.xmlsoap.
      org/soap/encoding/" namespace="soap.ws.web.raileurope.com"



      I asked the programmer who wrote the WS to send some sample code.
      :::Here is his Java 5.0 code:::
      String key = null;
      String locale = null;
      String[] countriesCovered = null;
      Attribute[] attributes = null;

      key = "123456";
      countriesCovered = new String[1];
      countriesCovered[0] = "FR";

      TestService _service = new TestServiceLocator();
      Test _ptr = _service.getRailEuropeWebService();

      SearchResult result = _ptr.doSearch(key, locale, null,
      countriesCovered, attributes);

      I've thought about writting a wrapper Java class which I could use
      from my CF code to call the WS. Is this sensible? My thought was to
      use the function supplied above and just add an additional function
      which I would pass in the parameters from CF which would then convert
      all variables to the correct types and call the WS. I've not actually
      tested the supplied Java code yet so I'm not even sure it will work. I
      was hoping to get it working directly from CF.

      I'm off to find a Java book on WS! :) Hope someone can help!

          This is crazy! Someone must have come across this problem before.

          I've simplified my question and used a much simplier method from the web service, here goes!
          ::: Here's my code :::
          webservice = CreateObject("webservice","dummy?wsdl");

          ::: Here's the error :::
          Could not perform web service invocation "doBuildQuoteForItinerary".
          Here is the fault returned when invoking the web service operation:<br> <pre>AxisFault faultCode: { http://schemas.xmlsoap.org/soap/envelope/}Server.userException faultSubcode: faultString: com.raileurope.web.ngserver.InternalErrorException: java.lang.NullPointerException faultActor: faultNode: faultDetail: { http://xml.apache.org/axis/}hostname:dummy </pre>

          There must be something wrong with how I'm passing in the parameters. Is it the null string??!?!?

          Any help would be great!
