What is VMforce?

We run it for you in our cloud

Managed Java StackAutomatic Scalability

Backups and DR

Pre-integrated to Force.com database

Develop your Java app locally

EclipseSpring Framework

JPA

Your Java apps can leverage Force.com services

Relational cloud databaseSecurity & user management

Search & Chatter APIsReporting

Why VMforce?

We run it for you in our cloud

No complex HW and SW stacks to build,

tune, scale, patch and upgrade

Trusted performance, reliability, backup, and

disaster recovery

Develop your Java app locally

Leverage existing Java skills and assets

Your Java apps can leverage Force.com services

Centralize data managementCentralize user management

Faster time-to-value

But we’re Force.com developers,How can we take advantage of VMforce and Spring?

VMforce Multi-tenant JVM Cloud

JVM

Servlet Engine

It gets its own servlet engine and JVM

How VMforce Works

.war

You deploy a Java Web App

It connects to Force.com using existing APIs with JPA layer

Force.com

API

Force.com is the database for your Java app

Your app gets search, reporting, mobile and all other Force.com services out of the box

Integration Apps

VMforceApp app = new VMforceApp();Policies__c[] result =app.getPolicies(customerId);

public SObject[] getPolicies(String id) { return convert2SObject( soap.getPolicies(id));}

Force.com Java App On-prem

Delegate complex integration logic to Java tier

Reuse existing Java assets (e.g., mapping, parsing logic)

Delegate work to Java skilled people

Data Processing Apps

VMforceApp app = new VMforceApp();SObject[] result = app.process(sobjects);

public SObject[] process(SObject[] input) { return myMagician.performMagic(input);}

VMforceApp app = new VMforceApp();app.process(sobjects,callback);

public void callback(SObject[] result) { checkResults(result);}

Force.com VMforce App

sync

async

Delegate heavy-weight processing to Java tier

Reuse existing Java assets, libraries etc

Delegate dev work to Java skilled people

About SpringSource

SpringSource is the organization that develops the

Spring framework, the leading enterprise Java

framework

SpringSource was acquired by VMware in 2009

VMware and SpringSource are working with

salesforce.com to build a best-of-breed, next generation

cloud for Spring and Salesforce developers alike

Spring’s Aim: Bring Simplicity to Java Development

The Spring Framework (lay of the land)

Framework Description

Spring framework The foundation

Spring Security (a.k.a. Acegi) Extensible framework providing authentication, authorization and instance-level security

Spring Web Flow An excellent web framework for building multi-page flows

Spring Web Services Contract-first, document–centric SOAP and XML web services

Spring Dynamic Modules for OSGI Deploy Spring applications on OSGI

Spring Batch Powerful batch processing framework

Spring Integration Implements enterprise integration patterns

Spring BlazeDS integration Support for Adobe BlazeDS

SpringSource dm Server OSGI based application server

Spring AMQP Framework to interface with AMQP message brokers

At Its Core…Spring Framework is:

The de-facto standard in lightweight Java enterprise

applications

Unified Component Model – Plain Old Java Objects

(POJOs!)

(from day one!)

Inversion of Control / Dependency Injection

Aspect Oriented Programming

Best Practices-Oriented– N-Tier architectures

Demo 1

Here, we walk through getting STS

Creating a new preconfigured Maven project from STS

Writing a main() method and launching a Spring context– This live coding will go up until we have injected a

Map<String,Object> into a service impl

Demo 1: Recap for Force.com Developers

Spring Force.com

Java Language Syntax similar to Apex

STS Force.com IDE

POJOs Standard/Custom objects without DML

Develop Locally Develop in the Cloud

Dependency Injection Extract logic from code/app similar to meta-data

Spring’s Data Access APIs

Flexible– No vendor lock-in:

• Built on Standards like JPA (Java Persistence Architecture)

• Popular alternative implementations: Hibernate

• Simplifying APIs for straight JDBC

– Very clean APIs• You write the code that’s relevant for your business, leave

boilerplate to Spring

Demo 2

Walk through setting up JPA – (will demonstrate using the STS support to add Maven

dependencies)

Demo 2: Recap for Force.com Developers

Spring Force.com

Data Access API DML Operations

JDBC DB Connectivity handled by platform

JPA – Java Persistence Architecture– Preferred Java standard for data access

– VMforce will provide a JPA adapter to connect to Force.com DB

Spring’s Web Tier Support

Web Containers Offer Servlet API– Servlets are low level request/response handlers in a Java web

server (like Tomcat, or SpringSource’s tcServer)

Spring @MVC framework sits on top of Servlet API

Spring & MVC

Demo 3

Walk through using our existing CustomerService

from a simple web application and then

Demo 3: Recap for Force.com Developers

Spring Force.com

Annotations Operate the same as @future, @istest annotations

Web Container Force.com Org

Spring MVC Force.com MVC

Maven Builds handled by platform

Summary

VMforce enables Java developers to

reach the Cloud– And leverage Force.com Services

(search, reporting, mobile etc)

Force.com developers can leverage

VMforce– leverage Spring (existing apps, logic

etc)

– Will only require a JPA config change

Spring Simplicity– And leverage existing developer

skillsets
