Default Getting JVM error 104 - uncaught null pointer exception

Please Login to Remove!

Hi friends. After a wide search i got a sample code for calling amazon web service which is as follows



public void obtenerArticuloSOAPYahoo(String id) {

HttpTransport ht = null;
SoapSerializationEnvelope envelope = null;
try
{
SoapObject rpc =
new SoapObject("urn:PI/DevCentral/SoapService", "KeywordSearchRequest");


SoapObject ro = new SoapObject("urn:PI/DevCentral/SoapService", "KeywordRequest");

ro.addProperty("keyword", "dog");
ro.addProperty("tag", "webservices-20");
ro.addProperty("type", "lite");
ro.addProperty("mode", "book");
ro.addProperty("page", "1");
ro.addProperty("devtag", "your-dev-tag");

rpc.addProperty("KeywordSearchRequest", ro);

new SoapSerializationEnvelope(SoapEnvelope.VER11);

envelope.bodyOut = rpc;

ht = new HttpTransport("h t t p ://soap.amazon.com/onca/soap3");
ht.debug = true;

ht.call("h t t p ://soap.amazon.com/onca/soap3", envelope);

System.err.println ("call" + ht.responseDump);
SoapObject result = (SoapObject) envelope.getResult();
}
catch (SoapFault f)
{
System.err.println( ht.requestDump );
System.err.println( ht.responseDump );
System.err.println( f.faultstring );

}
catch (Exception e)
{
System.err.println(" excep::req::" + ht.requestDump );
System.err.println(" excep:resp:" + ht.responseDump );
//System.err.println( e.faultstring );

}

}

Are you running this on the simulator, using the debugger?

If so, can you please do a little problem determination, and identify the line where the NPE is thrown?
