UrgentHelp: XmlPullParserException UnsupportedEncoding

Hi list,

I have a problem to run my application on mobile devices. There are no
exceptions on Java J2ME WirelessToolkit (2.0) - I think the webservice
works fine!
Now my problem: On Sony-Clie Palm (kJVM MIDP4Palm) and Casio E-200
PocketPC (kJVM KadaSystems) are errors in HttpTransport, in the code:

The ht.call(..) method has an XmlPullParserException:

"Invalid stream or encoding: java.io.UnsupportedEncodingException:
UTF-9 (position:START_DOCUMENT null@0:0) caused by:
java.io.UnsupportedEncodingException UTF-8"

See code below:

> String symbol = "test test";
> 
> SoapObject rpc =
>     new SoapObject("urn:HelloWorld", "sayHello");
> 
> rpc.addProperty("symbol", symbol);
> 
> SoapSerializationEnvelope envelope =
>     new SoapSerializationEnvelope(SoapEnvelope.VER10);
> 
> envelope.bodyOut = rpc;
> 
> HttpTransport ht = new HttpTransport("http://mydomain/servlet/rpcrouter");
> 
> ht.debug = true;
> 
>  try {
>      ht.call("urn:HelloWorld#sayHello", envelope);
>  }
>  catch (Exception e) {
>     error += e.toString();
>  }


Is this problem solved by other encoding? How can I change the
Encoding?

Lot of thanks,

Thomas Stark
