Soap Throws java.io.IOException: HTTP request failed, HTTP status: 500

问题

Actually I used this code to access this web service FahrenheitToCelsius Method, am getting the correct response, but when I tried to access my webservice am getting

java.io.IOException: HTTP request failed, HTTP status: 500

error and it is pointing the transport.call(SOAP_ACTION, envelope);

SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);                     
//Use this to add parameters                              
request.addProperty("username",usr);
request.addProperty("password",pass);
request.addProperty("backOfficePartnerId",id);

//Declare the version of the SOAP request
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER10);

envelope.setOutputSoapObject(request);

envelope.dotNet = true;

try {
    HttpTransportSE transport = new HttpTransportSE(URL);

    Log.i("bodyout", "" + envelope.bodyOut.toString());

    transport.call(SOAP_ACTION, envelope);      

    // Get the SoapResult from the envelope body.
    SoapObject result = (SoapObject)envelope.bodyIn;
    System.out.println("result IN F TO C::"+result);
}catch(Exception e){
    e.printStackTrace();
}

Am getting the correct response till here. I debuged and checked the values am sending the body out that is correct and in response for me the bodyin is null.

回答1:

The HTTP Status: 500 is an internal server error and it probably has something to do with your .NET server side coding.

回答2:

change VER10 to VER11. SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11) working for me

I searched a lot but couldn't find any specific solution. I solved my problem by downloading new server package(of same version) and replaced the previous server package by new one .(about Apache tomcat 7)
