Use Salesforce SOAP API with JavaHow do you connect to Salesforce from an external application, say, for example Java? If you Google for the information, you will quickly learn that Salesforce provides different methods and different APIs. But what you will probably not find is a step-by-step guide teaching you exactly how to do it. In this blog post, I have stitched together a complete step-by-step instructions with screenshots on how to download, install, configure and use Salesforce’s SOAP API to connect from a java program and execute some basic transactions (query, insert, update, delete records). In less than 60 minutes, you will have a fully functional java program that will connect to Salesforce and execute transactions in Salesforce.

The guide includes downloading necessary WSDLs from Salesforce, creating & packaging the required components in a JAR file, referencing the JAR file in your java program, logging on to Salesforce from the java program, querying and manipulating data. Here is an overview of steps that needs to be completed and is covered in the guide

  • Install Java
  • Install Eclipse
  • Install Force.com WSC (Web Services Connector)
  • Install Maven
  • Generate JAR Files
  • Download WSDL Files From Salesforce
  • Generate Java Stub File
  • Create Java Program
  • Execute Transactions using SOAP API

(Once you are done with this, you may also want to explore my other blog post Step-By-Step Guide to Get Started with Salesforce REST API using Java to learn how to get started with Salesforce REST API using Java or explore A 60 Minutes Step-By-Step DIY Guide to Salesforce REST API for Non-Developers to get started with REST API without going through the hassles of writing a Java program)

Even if you are not a developer, you should be able to follow the guide and have working java program at the end of it.  Sounds interesting? Download the following presentation and let’s get started…

Here is the URL to get the code used in this guide

  1. Java program to connect to test connecting to Salesforce 
  2. Java program to query, create, update & delete records in Salesforce

In these codes, I have used simple SOAP API calls like query(), create(), update() & delete() to give you a taste of how to use APIs. For complete reference on Salesforce SOAP API listing all calls, objects, fields and other details please refer to SOAP API Developer’s Guide

Not only this, you can go a step further and use other SOAP/WSDL based APIs that Salesforce provides to extract and manipulate data and metadata. For a list of different APIs along with a brief explanation on which API should be used when, please navigate to URL https://help.salesforce.com/HTViewHelpDoc?id=integrate_what_is_api.htm
