System.TypeException when doing callout

Hey I am getting an Invalid decimal exception.

Fatal error:system.typeexception..invalid decimal:B4DODC

Here is my class:

 

  @future(callout=true)
  public static void updateAccounts(List<Id> accountIds)
  {
  // get the custom city, state and country fields from account
    //List<Account> accounts = [select Id, Name, BillingCity, BillingState, BillingCountry
      //from Account where Id in :accountIds ];
    for(Account theAccount: [select Id, Name, BillingCity, BillingState, BillingCountry from Account where Id in :accountIds ]) { 
      
      List<String> address = new List<String>();
      address.add('');// empty street
      address.add(theAccount.BillingCity);
      address.add(theAccount.BillingState);
      address.add(theAccount.BillingCountry);
      String[] coordinates = GeoUtilities.getCoordinates(address);
      if(coordinates != null)
      {
        Decimal pos1 = Decimal.valueOf(coordinates[0].trim());
        theAccount.Latitude__c = pos1;
        Decimal pos2 = Decimal.valueOf(coordinates[1].trim());
        theAccount.Longitude__c = pos2;
        system.debug(Logginglevel.ERROR,'GeoUtilities coordinates ' + pos1 + ' ' + pos2 );    
      }
      else
      {
        system.debug(Logginglevel.ERROR,'GeoUtilities no coordinates!!! for address' );          
      }
      update theAccount; 
    }
    
  }

   
   public static String[] getCoordinates(String[] addressParts)
    { 
      String[] Coordinates; 
      String address = '';
      boolean needComma = false;
      system.debug(''+address);
      system.debug(''+address.length());
      
      for(Integer i = 0; i<10; i++)
        {
          if(needComma)
            address = address + ',';
          address = address + EncodingUtil.urlEncode(address,'UTF-8');
          needComma = true;
        }
    
	  if(address.length() == 0)
	  {
	    system.debug(Logginglevel.ERROR,
	      'GeoUtilities getCoordinates no address provided. Return null');    
	    return null; 
	  }
      system.debug(''+address);
      system.debug(''+address.length());
      
	  String url = 'http://geocoder.us/member/service/csv/geocode?q=street=701+First+Ave&city=Sunnyvale&state=CA&country=USA';
	  
	  //url += 'q=' + address; 
	  //url += '&output=csv'; 
	  
	  system.debug(Logginglevel.ERROR,'GeoUtilities getCoordinates url: ' + url);    
	  
	  Http h = new Http(); 
	  HttpRequest req = new HttpRequest();
	  
	  req.setHeader('Content-type', 'application/x-www-form-urlencoded'); 
	  req.setHeader('Content-length', '0'); 
	  req.setEndpoint(url); 
	  req.setMethod('POST');
	  String responseBody;
	  if (!Test.isRunningTest())
	  { 
	  // Methods defined as TestMethod do not support Web service callouts
	    HttpResponse res = h.send(req); 
	    responseBody = res.getBody();
	  }
	  else 
	  {
	    // dummy data
	    responseBody = '200,4,48.5,-123.67';
	  } 
	  String[] responseParts = responseBody.split(',',0); 
	  // the response has four parts: 
	  // status code, quality code, latitude and longitude
	  Coordinates = new String[2];
	  Coordinates[0] = responseParts[2];
	  Coordinates[1] = responseParts[3];
	    
	  return Coordinates; 
	 
	  }
  
  static testMethod void  testGetGeo()
  {
    String[] addressParts;
    String[] coordinates;
    
    addressParts = new List<String>();
    addressParts.add('');
    addressParts.add('San Diego');
    addressParts.add('CA');
    addressParts.add('USA');
    
    coordinates = GeoUtilities.getCoordinates(addressParts);
    System.assert(coordinates != null);
    System.assertEquals(2, coordinates.size()); 
  }
}

 

I have added the URL in the req.setEndpoint.

I was trying to use Trim() and Decimal.valueOf().
But none of them is working.

Here i had a Latitude__c and Longitude__c as Number fields.So i am trying to convert the result to decimal value.

Have anybody faced this issue.

Hi,

The error says that you are truing to conert string to Decimal. Please enclose your code in try catch and in case of exception, through fault message to client calling webservice.

rajjjjrajjjj

That worked for me....And after that i was getting the HTML Response but i am not able to parse it correctly.

Do u have any code which parses an HTML Response.

Like i was trying to get the latitude and longitude of an address. I want to parse the result and get those 2 values.

Please post your HTML response.

<p>
If you want to use the web services interface to the free service use these URL's, and do not add your username and password.
<p>

The service URLs are as follows:
<pre>
    http://geocoder.us/service/xmlrpc
    http://geocoder.us/service/soap
    http://geocoder.us/service/rest/...
    http://geocoder.us/service/csv/...
</pre>

The absolute simplest way to get a geocode from the free service is to use the csv interface. Entering this in your browser:
<p>
 http://rpc.geocoder.us/service/csv?address=1600+Pennsylvania+Ave,+Washington+DC
<p>
Returns this result:
<p>
38.898748,-77.037684,1600 Pennsylvania Ave NW,Washington,DC,20502
