Response Data Mapping Problems

Doug Haigh Mon, 03 Mar 2003 17:42:18 -0800

I am trying to write a Java client that uses Apache SOAP to connect to a service running gSOAP. I have tried to model it after the addressbook example in the Apache SOAP toolkit. Unfortunately, when I get back the response, instead of mapping the data into an AdapterInfo object, the QueryError is mapped as the response value and the other fields in the struct are stuck in an vector. Can someone please tell me what is going wrong?

Thanks

Code:

public class AdapterInfo
{
private int    QueryError;
private int    AdapterID;
private int    MemBase;
private int    IoBase;

public AdapterInfo()
{
}

public AdapterInfo(   int    QueryError,
                        int    AdapterID,
                        int    MemBase,
                        int    IoBase)
{
    this.QueryError         = QueryError       ;
    this.AdapterID          = AdapterID        ;
    this.MemBase            = MemBase          ;
    this.IoBase             = IoBase           ;
}

public void setQueryError(int QueryError)
{
this.QueryError = QueryError;
}

public int getQueryError()
{
return QueryError;
}

public void setAdapterID(int AdapterID)
{
this.AdapterID = AdapterID;
}

public int getAdapterID()
{
return AdapterID;
}

public void setMemBase(int MemBase)
{
this.MemBase = MemBase;
}

public int getMemBase()
{
return MemBase;
}

public void setIoBase(int IoBase)
{
this.IoBase = IoBase;
}

public int getIoBase()
{
return IoBase;
}

public String toString()
{
    return "Adapter ID        = " + AdapterID        + "\n" +
           "Query error       = " + QueryError       + "\n" +
           "Memory base       = " + MemBase          + "\n" +
           "IO base           = " + IoBase           + "\n";
}
}

public String GetAdapterInfo(int AdapterID) // Response???
{
String output = "";

    try
    {
      Call                call    = new Call();

      Response            resp;

       smr.mapTypes(Constants.NS_URI_SOAP_ENC,
                   new QName("urn:remote-adap", "GetAdapInfoResponse"),
                   AdapterInfo.class,
                   beanSer,
                   beanSer);

      call.setSOAPMappingRegistry(smr);
      call.setTargetObjectURI("urn:remote-adap");
      call.setMethodName("GetAdapterInfo");
      call.setEncodingStyleURI(Constants.NS_URI_SOAP_ENC);

        for (i=0; i < retParams.size(); i++)
        {

System.out.println("vector part "+i+" type=" + param.getValue().getClass());
}

System.out.println("output type=" + info.getClass());

output = info.toString();

        System.out.println("output=" + output);
      }
