Status Report for 02/01/07 to 02/07/07

I’ve just finished implementing a client (STFILTER) which will invoke time series analysis web service (AnalyzeTseriService). I added a web service version for time series analysis, called execATS. WSDL of execATS can be accessed at http://gf1.ucs.indiana.edu:8888/analyze-tseri-exec/services/AnalyzeTseriExec.

execATS needs the following 4 arguments as input:

1. String siteCode – Site code such as dhlg
2. String dataURL – Data file URL from which the server will download data file
3. double[][] globalParam – Parameters for global station. Array of (double Parameter type, double param_1, … , double param_n)
4. double[][] siteParam – Parameters for the specific station . Array of (double Parameter type, double param_1, … , double param_n)
   

A very simple example to create a client to invoke web service can be found at http://ws.apache.org/axis/java/user-guide.html#BasicsGettingStarted. In a nut shell, execATS web service can be executed from a client by using the following code:

String siteCode = "dhlg";
String dataUrl = "http://server:port/datafile";
double[][] globalParam = {
{ 7, 0.0, 50.0, 2005.0, 2008.0 },
{ 9, 0.0, 50.0, 2005.0, 2008.0 } };
double[][] siteParam = {
{ 8, 0.0, 50.0, 2005.0, 2008.0 } };

Service service = new Service();
Call call = (Call) service.createCall();

call.setTargetEndpointAddress(new java.net.URL(endpoint));
call.setOperationName(new QName("http://soapinterop.org/",
"execATS"));

String[] ret = (String[]) call.invoke(new Object[] {siteCode, dataUrl, globalParam, siteParam});
