Dear all,
I want to use Grid Service to wrap some standard Web Services,
so I write some samples.
First of all, I invoked a standard web service:
---------------------------------------------------------------------
public static void main(String[] args) {
String endpoint = " http://www.wopos.com/webservice/weather.asmx";;
Service service = new Service();
Call call;
try {
call = (Call) service.createCall();
try {
call.setTargetEndpointAddress( new java.net.URL(endpoint) );
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
call.setSOAPActionURI( " http://tempuri.org/HelloWopos"; );
call.setEncodingStyle( "
http://schemas.xmlsoap.org/soap/encoding/"; );
call.setOperationName("HelloWorld");
call.setReturnType( XMLType.XSD_STRING);
call.addParameter( "op1", XMLType.XSD_INT, ParameterMode.IN );
call.setUseSOAPAction(true);
try {
String str = (String)call.invoke(new Object[]{1});
System.out.print(str);
} catch (RemoteException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
} catch (ServiceException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
------------------------------------------------------------------------------------
The invoking result is successfull
Then I wrapped this web service with globus Grid service and build the
service,deployed the service like the "math" sample of the gt4
programming guide.
When I tried to use the client to invoke the grid service, it failed:
