Salesforce Force.com Canvas SDK

Introduction

Force.com Canvas is a mechanism for consuming third-party applications within Salesforce. Its goal is to connect applications at a UI level instead of just an API level. The purpose of this GitHub repository is to provide third-party applications with a Java/JavaScript SDK and examples so you can easily integrate canvas-style applications into Salesforce, while developing in the technology and platform of your choice.

The best place to get started building canvas applications is the online developer guide.

Currently, we provide Java examples in this repository, but you can develop in whatever language you prefer. Most of the integration with Salesforce is through JavaScript and REST. You can also run and test your application locally from your own host, or from Heroku.

Examples

This SDK contains some basic Java examples. We recommend you explore the Heroku Quick Start, for additional examples in Java and Ruby.

For other examples and resources, check out the developer guide.

Prerequisites

Below are some useful commands and links for your convenience. Before you use them, you'll need to make sure you have the necessary software installed on your computer here.

How to clone the SDK repository

git clone git@github.com:forcedotcom/SalesforceCanvasFrameworkSDK.git
cd SalesforceCanvasFrameworkSDK
git submodule init
git submodule update

How to build canvas locally

If you prefer, you can build and test your application locally before you push to Heroku or any other server. If you decide to test locally, you'll also need to generate a local keystore so you can do SSL.

mvn package

First time keystore generation

This is only needed to support SSL (https) when running locally. Heroku uses piggyback SSL so it's not needed there.

  > keytool -keystore keystore -alias jetty -genkey -keyalg RSA
  Enter keystore password: 123456
  Re-enter new password: 123456

How to run canvas locally

If you're running and testing locally, this will start your Java Web server.

sh target/bin/webapp

Canvas URL

If you're running locally 
https://localhost:8443/examples/hello-world/index.jsp

Or if you're running on Heroku
https://<your-heroku-app>.herokuapp.com/examples/hello-world/index.jsp

Canvas callback URLs

If you're running locally
https://localhost:8443/sdk/callback.html

Or if you're running on Heroku
https://<your-heroku-app>.herokuapp.com/sdk/callback.html

How to push new changes to Heroku

To commit your changes into your local git repository and push those changes to Heroku, use these commands. Note that your repository name may be diffferent than 'heroku', use git remote -v to confirm.

  git add -A
  git commit -m "My change comments"
  git push heroku master

How to get Heroku logs
