Hi Seonho, sorry I may not have fully understood your requirement, are you looking to create GeoFence with your data? something like this

[CHASEONHO]

No

i want get address value base on longitude,latetude

if i got 39.773844,-89.643711 . i get USA Illinois Springfield base on that value

thanks

i don't need geoFence yet

Dear seonho Cha,

One solution I could imagine is to customize an extension of your own.

In the Java Extension you could utilize the Google open API to get Address inforamtion based on a Location.

Sample code like this:

@ThingworxServiceDefinition( name="GetAddressFromLocation", description="get address from a location" )
 @ThingworxServiceResult( name="Result", description="Result", baseType="STRING" )
 public String GetAddressFromLocation(
   @ThingworxServiceParameter( name="longitude", description="", baseType="NUMBER" ) Double longitude, 
   @ThingworxServiceParameter( name="latitude", description="", baseType="NUMBER" ) Double latitude
   ) throws Exception {
  String address = GetLocationMsg(latitude,longitude);
  return address;
 }
public static String GetLocationMsg(double latitude,double longitude){
  String message = "";
          String url = String.format(
              "http://maps.google.cn/maps/api/geocode/json?latlng=%s,%s&language=CN",
              latitude,longitude);
          URL myURL = null;
          URLConnection httpsConn = null;
          try {
              myURL = new URL(url);
          } catch (MalformedURLException e) {
            e.printStackTrace();
          }
          try {
              httpsConn = (URLConnection) myURL.openConnection();
              if (httpsConn != null) {
                  InputStreamReader insr = new InputStreamReader(
                          httpsConn.getInputStream(), "UTF-8");
                  BufferedReader br = new BufferedReader(insr);
                  String data = null;
                  while ((data = br.readLine()) != null) {
                  message = message+data;
                  }
                  insr.close();
              }
          } catch (IOException e) {
              e.printStackTrace();
          }
  return message;
  }

This will return a JSON address message, you could then parse this JSON file for the exact address you want.

Thanks,

Br,

Dear Seohno Cha,

Firstly you could create a service in Thingworx composer, say, getAddString Service.

Then you could code in the Service like:

//var url = "http://maps.googleapis.com/maps/api/geocode/json?latlng=39.773844,-89.643711";
var url = "http://maps.googleapis.com/maps/api/geocode/json?latlng="+latitude+","+longitude;
var params = {
  proxyScheme: undefined /* STRING */,
  headers: undefined /* JSON */,
  ignoreSSLErrors: undefined /* BOOLEAN */,
  useNTLM: undefined /* BOOLEAN */,
  workstation: undefined /* STRING */,
  useProxy: undefined/* BOOLEAN */,
  withCookies: undefined /* BOOLEAN */,
  proxyHost: undefined/* STRING */,
  url: url /* STRING */,
  timeout: undefined /* NUMBER */,
  proxyPort: undefined/* INTEGER */,
  password: undefined /* STRING */,
  domain: undefined /* STRING */,
  username: undefined /* STRING */
};
var json1 = Resources["ContentLoaderFunctions"].GetJSON(params);
var result = json1.results[0].formatted_address;

input:

latitude:NUMBER

longitude:NUMBER

output: STRING   

Hope this helps,

Br,

Anna

Dear seonho cha,

What's the difference between your visiting ThingWorx the last time it was working fine and the last time it was not working fine(got the error you attached above)? For example, did you use https://<IP>:<PORT>/Thingworx/Composer to access thingworx when it failed? do you visit with unsecure visit like http://<IP>:<PORT>/Thingworx/Composer to visit Thingworx when it succeeded to execute GetJSON?

Or, did you use a different JDK to run ThingWorx between the two tests?

What's the OS you are running ThingWorx instance? Linux or Windows?

From the error, I googled it:Unable to Access SSL Services due to java.security.InvalidAlgorithmParameterException - Atlassian Documentation

It looks like The JVM cannot find the javax.net.ssl.trustStore required for SSL, or it does not contain the required certificates.

Please check your environment and have one more test today and let me know of your test result.

please also take reference to this disucussion: java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty on Linux, or why is the d…

Thanks,

Br,

Anna

Dear seonho cha,

Please use HTTP instead of HTTPS which will verify SSL connection.

It works on my side with the url:

var url = "http://maps.googleapis.com/maps/api/geocode/json?latlng="+latitude+","+longitude;

[CHASEONHO]

thanks your kind!!

you're angel!! really thanks
