I have a custom class that is creating a JSON file (served up by a visualforce page). 

Is it possible to have an API call go out and retrieve this file and save it somewhere else? 

I am very, very new to this, so any pointers would be highly appreciated! 

Hello, 

I new still new to APEX and have a class that generates some JSON, but can't figure out how to write a test class for it... I have written test classes before, but not for a page controller that just serves up JSON... 

Thanks!

public class Json_Controller {
    
    public string json {get;set;}
        
    public Json_Controller() {      
        VQ_Reference_Sheet__c[] vqr = new VQ_Reference_Sheet__c[]{};
        integer start = 0;
        integer pageSize = 100;
        
        if (ApexPages.currentPage().getParameters().get('start') != null && ApexPages.currentPage().getParameters().get('limit') != null) {
            start = integer.valueof(ApexPages.currentPage().getParameters().get('start'));
            pageSize = integer.valueof(ApexPages.currentPage().getParameters().get('limit'));
        }
        
        string jsonRecordsString = '';
        
        integer i = 1;
        integer j = 0;
        
        for (VQ_Reference_Sheet__c v : [Select 
        
        id, 
        name, 
        Times_Referenced_Used_Total__c, 
        Hardware_Platform__c
              
        
        from VQ_Reference_Sheet__c order by name limit 1000]) {
            if (j >= start) {
                if (i <= pageSize) {
                    jsonRecordsString += '{';
                //record info      
                    jsonRecordsString += '"label":' + '"'+v.name+'",';  
                    jsonRecordsString += '"use":' + '["'+v.Times_Referenced_Used_Total__c+'"],';
                    jsonRecordsString += '"hrd":' + '["'+v.Hardware_Platform__c+'"],';
                    
                //record id    
                    jsonRecordsString += '"sfdcid":' + '"'+v.id+'",';
                    jsonRecordsString += '},';
                    i++;
                }
            }
            vqr.add(v);
            j++;
        }
        
      //lets do some clean-up   
            jsonRecordsString = jsonRecordsString.replaceAll(' 00:00:00','');
            jsonRecordsString = jsonRecordsString.replaceAll(';','","');
            jsonRecordsString = jsonRecordsString.replaceAll('null','');
            jsonRecordsString = jsonRecordsString.replaceAll('"latlng":","','"latlng":""');
               
        string jsonString = 'sfdccallback({ types: {"Reference" : {pluralLabel: "References"}},"items":[' + jsonRecordsString + '], "properties" : {"rev" : {"valueType" : "number"}, "emp" : {"valueType" : "number"}}   })';
        jsonString = jsonString.replaceAll(',]',']');
        this.json = jsonString;

    }
}

I have started something like this just to see if I can get it to  work, but still not success: 

@isTest
private class ControllerTest {
    static testMethod void Json_Controller() {
        Json_Controller controller = new Json_Controller();
        System.assertEquals(json.substring(0, 12),'sfdccallback');
    }
}

Hello, 

I am looking to create a vf page within the account page that will show all related account records based on a field called Ultimate_Parent_ID__c. The idea being that it will show all the sites for a given company. 

I already have the latlng coordinates stored on the account object, and a controller to query the related accounts (see below) but I can't seem to get them to plot on a google map. I have been looking around the various tutorials, but they all seem to go over how to geocode them, or how to show only 1 point on the map. 

Any help would be greatly appreicated! 

public class mapController2 {
    public String address {get;set;}
    private List<Account> accounts;

    public void find() {
        accounts = [SELECT Id, Name, BillingStreet, BillingCity, BillingCountry, BillingLat__c, BillingLong__c FROM Account 
        WHERE Ultimate_Parent_ID__c = :ApexPages.currentPage().getParameters().get('Account.Ultimate_Parent_ID__c')];
        
    }

    public List<Account> getAccounts() {
        return accounts;
    }
}

I am working on a trigger that will populate longitude and latitude fields on the account object. I have a start on it, but I am getting an error:

"Error:Apex trigger AccountBeforeUpsert caused an unexpected exception, contact your administrator: AccountBeforeUpsert: System.LimitException: Too many script statements: 200001"

I have embed a google maps in one of my custom objects. Based on the customer's address, the map is being displayed on the page. But how can I generate geocode (latitude and longitude) for the address? Any suggestions please.

Thank you in advance!

i want to read values from the text box on visual force page is it possible  to read from visual force using java api. if yes then how can i do that??
