Subject Re: WSIF complexsoap dynamic client
Date Sun, 02 Nov 2003 23:59:07 GMT
Hello Nirmal,
Thanks a lot for your response.
Actually my problem is : I am trying to invoke the "getCountries" method similar to the sample
example shown in WSIF samples. 
 
<types>                     
- <s:element name="getCountries">
  <s:complexType /> 

  </s:element>


- <s:complexType name="ArrayOfString">
- <s:sequence>
  <s:element minOccurs="0" maxOccurs="unbounded" name="string" nillable="true" type="s:string"
/> 

  </s:sequence>


  </s:complexType>


- <s:element name="getCountriesResponse">
- <s:complexType>
- <s:sequence>
  <s:element minOccurs="0" maxOccurs="1" name="getCountriesResult" type="s0:ArrayOfString"
/> 

  </s:sequence>


  </s:complexType>
 
As  "getCountries" method return an object of "ArrayOfString" I am trying to map it.




 
                 // map types
       service.mapType(
     new QName("http://www.abundanttech.com/WebServices/Population", "ArrayOfString"),
              Class.forName(
                  "com.abundanttech.www.ArrayOfString"));
 
But still it say's it is unable to deserialize "getCountriesResponse" 
so I am mapping it
 
service.mapType(
     new QName("http://www.abundanttech.com/WebServices/Population", "getCountriesResponse"),
              Class.forName(
                  "com.abundanttech.www.GetCountriesResponse"));
 
After executing the method
    operation.executeRequestResponseOperation(input, output, fault)
 
I am getting the following errors: I am not understanding why it is unable to get the Object
Part for "getCountriesResult" where as the samething works fine for your sample.
 
LatLongReturn zipInfo =
      (LatLongReturn) output.getObjectPart("GetLatLongResult");
 
 
Exception in thread "main" org.apache.wsif.WSIFException: Cannot get part 'getCo
untriesResult'. Part was not found in message
        at org.apache.wsif.base.WSIFDefaultMessage.handlePartNotFoundException(U
nknown Source)
        at org.apache.wsif.base.WSIFDefaultMessage.getObjectPart(Unknown Source)

 
I am not understanding what I am missing.
When I do the 
WSIFUtils.getWrappedDocLiteralPart(outParts ,opName+"Response");
for "getCountries" method I am not able to get the Parts which are under <types> of
the wsdl.
I am wondering is there a way to display the results in raw xml format?

 
Any suggestions would be of great help to me
Thanks,

Hi, 

Please post your queries to wsif-user@ws.apache.org. 

It looks like you haven't mapped the complex types in your response message. The exception
is pretty clear in saying that it doesn't know how to deserialize {http://www.abundanttech.com/WebServices/Population}getCountriesResponse,
that is to say it doesn't know how to convert an XML element of this type to a java object.

        Subject:        WSIF complexsoap dynamic client


Hello , 
As my school project I am trying to invoke webservices dynamically for which I am using your
example for complexsoap dynamic client. I am using WSIF 2.0. I am using this code for invoking
the Population web service.I am enclosing the wsdl doc as an attachment.I made the following
changes to invoke the "getCountries" method . I am enclosing the below code as an attachment.

  
public class CmplxSoap_population_test {
   public static void main(String[] args) throws Exception { 
        /* args[0] is the zip code
       if (args.length != 2) {
           System.out.println(
               "Usage: java complexsoap.client.dynamic.Run <wsdl location> <zip code>");
           System.exit(1);
       }
 */ 
        // create a service factory
       WSIFServiceFactory factory = WSIFServiceFactory.newInstance();
       WSIFService service =
           factory.getService(
               args[0],
               null,
               null,
               "http://www.abundanttech.com/WebServices/Population",
               "PopulationWSSoap"); 
        // map types
       service.mapType(
     new QName("http://www.abundanttech.com/WebServices/Population", "ArrayOfString"),
              Class.forName(
                  "com.abundanttech.www.ArrayOfString"));
  
       // get the port
       WSIFPort port = service.getPort(); 
        // create the operation
  
       WSIFOperation operation = port.createOperation("getCountries"); 
        // create the input, output and fault messages associated with this operation
       WSIFMessage input = operation.createInputMessage();
       WSIFMessage output = operation.createOutputMessage();
       WSIFMessage fault = operation.createFaultMessage(); 
        // populate the input message
      // input.setObjectPart("strCountry", args[1]);
     //  input.setObjectPart("LicenseKey", ""); 
  

       // do the invocation
//try{
 //operation.executeInputOnlyOperation(input);
     if (operation.executeRequestResponseOperation(input, output, fault)) {
           // invocation succeeded, extract information from output
           // message 

           Object zipInfo =
              output.getObjectPart("getCountriesResult"); 
  
                Class cl = zipInfo.getClass();
             System.out.println(zipInfo.getClass().getName()); 
              Method[] mem = cl.getDeclaredMethods(); 
              for(int i =0; i< mem.length; i++){ 
      if(mem[i].getName().startsWith("get") && (mem[i].getParameterTypes().length)
== 0)
     {
     System.out.println((mem[i].invoke(zipInfo,null)).toString()); 
      } 

    } 
 System.out.println(mem[7].getName()); 
 } 
} 
  
  
  
But I am getting the following errors: Any help will be of great help to me
