Salesforce Connector for JAVA

In this article you will learn how to integrate Salesforce data in JAVA (live / bi-directional connection to Salesforce). Salesforce Connector can be used to extract/load large amount of data from/in Salesforce.com without any programming. You can use simple Table mode or Query mode with full SOQL query language support (SOQL=Salesforce.com Object Query Language)..

Using Salesforce Connector you will be able to connect, read, and write data from within JAVA. Follow the steps below to see how we would accomplish that.

Create Data Source in ZappySys Data Gateway based on ZappySys Salesforce Driver

  1. Download and install ZappySys ODBC PowerPack.

  2. Search for gateway in start menu and Open ZappySys Data Gateway:
    Open ZappySys Data Gateway

  3. Go to Users Tab to add our first Gateway user. Click Add; we will give it a name tdsuser and enter password you like to give. Check Admin option and click OK to save. We will use these details later when we create linked server:
    ZappySys Data Gateway - Add User

  4. Now we are ready to add a data source. Click Add, give data source a name (Copy this name somewhere, we will need it later) and then select Native - ZappySys Salesforce Driver. Finally, click OK. And it will create the Data Set for it and open the ZS driver UI.

    ZappySys Data Gateway - Add Salesforce Data Source

  5. Now, we need SalesForce Connection. Lets create it. ODBC SalesForce Driver - Create Connection

  6. Now, When you see DSN Config Editor with zappysys logo first thing you need to do is change default DSN Name at the top and Click on Preview Tab, Select Table from Tables Dropdown or you can enter or modify a SOQL query and click on Preview Data.
    This example shows how to write simple SOQL query (Salesforce Object Query Language). It uses WHERE clause. For more SOQL Queries click here.
    SOQL is similar to database SQL query language but much simpler and many features you use in database query may not be supported in SOQL (Such as JOIN clause not supported). But you can use following Queries for Insert, Update, Delete and Upsert(Update or Insert record if not found).

    SELECT * FROM Account WHERE Name like '%Oil%'
    ZappySys ODBC Driver - Select Table and Preview Data
  7. Click OK to finish creating the data source

Read data in Java from the DSN

  1. Java code to get the data:

    "jdbc:sqlserver://localhost:5000;databasename=SalesforceDSN;user=tdsuser;password=test"
    Java code to Make ZappySys Driver Data Source Call

  2. When you run the code it will make the API call and read the data:
    Java code ZappySys Driver Data Source Results

  3. Here is Java program's code in text format:

    
    //Step-1: Install ZappySys ODBC PowerPack and Configure Data Gateway
    
    //Step-2:Assuming the Microsoft SQL Server JDBC Driver is in below folder
    //C:\Program Files\Microsoft Jdbc Driver 6.0 for SQL Server\sqljdbc_6.0\enu\auth\x64
    package padaone;
    
    import java.sql.*;
    
    public class zappy {
    
        public static void main(String[] args) {
    
            // Create a variable for the connection string.
            String connectionUrl = "jdbc:sqlserver://localhost:5000;databasename=SalesforceDSN;user=test;password=test";
    
            // Declare the JDBC objects.
            Connection con = null;
            Statement stmt = null;
            ResultSet rs = null;
    
                try {
                    // Establish the connection.
                    Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
                    con = DriverManager.getConnection(connectionUrl);
    
                    // Create and execute an SQL statement that returns some data.
                    String SQL = "SELECT Country , SUM(UnitPrice * Quantity) Total " 
                               + "FROM value " 
                               + "GROUP BY Country "
                               + "WITH (SRC='https://services.odata.org/V3/Northwind/Northwind.svc/Invoices?$format=json')";
                    stmt = con.createStatement();
                    rs = stmt.executeQuery(SQL);
    
                    // Iterate through the data in the result set and display it.
                    while (rs.next()) {
                        System.out.println(rs.getString(1) + " " + rs.getString(2));
                    }
                }
    
            // Handle any errors that may have occurred.
            catch (Exception e) {
                e.printStackTrace();
            } 
            
            finally {
                if (rs != null) try { rs.close(); } catch (Exception e) {}
                if (stmt != null) try { stmt.close(); } catch (Exception e) {}
                if (con != null) try { con.close(); } catch (Exception e) {}
            }
        }
    }
