Sending a float using Axis

[Jon Kurland]

I am trying to send a float parameter to a soap server and I keep getting the 
following error:

org.xml.sax.SAXParseException: Character conversion error: "Unconvertible UTF-8 
character beginning with 0x90" (line number may be too low).

Does anyone know how I can go about fixing this.  I believe that my client code, 
written in java, is sending a string not a float to the server.  I am attaching my 
code below.  Thanks in advance for your help, JK

import org.apache.axis.client.Call;
import org.apache.axis.client.Service;

public class AxisTest
{
   public static void main(String [] args) {
       try {
           String endpoint ="http://localhost:8585/";;
 
           Service  service = new Service();
           Call     call    = (Call) service.createCall();
           call.setTargetEndpointAddress( new java.net.URL(endpoint) );
           call.setOperationName( "Hello" );
           call.setProperty( Call.NAMESPACE, "urn:gethello" );
           call.setProperty(Call.TIMEOUT, "10000");
           call.addParameter( "Var1", org.apache.axis.encoding.XMLType.XSD_FLOAT, 
Call.PARAM_MODE_IN );
           call.setReturnType( org.apache.axis.encoding.XMLType.XSD_FLOAT );

                   Object ret = call.invoke( new Object[] {"1"} );
 
           System.out.println(ret);
       } catch (Exception e) {
           System.err.println(e.toString());
       }
   }
}
